A coffee replacement drink: from the home of kenneth jay

Today Kenneth Jay of ThreatModulation introduced some of us to a drink to which his partner had introduced him. He says one of the biggest effects of the beverage is that his high octane desire for coffee (can we say tripple shots) has gone way way down. I got to try it today, and yup, it was very satisfying as well as alleviating that urge to splurg on coffee coffee coffee.

here's the recipe as i understood it - and as kenneth generously let me practice is with some of his fresh ingredients:
  • fresh ginger, julienned
  • fresh lemon slices - i used about a half of a small
  • caynne pepper powder - i used a big pinch
  • honey - i used a tablespoon
  • hot water - i think it was a little better than a liter
  • steep for about three minutes - maybe it was five
Very very nice.

Variations in proportions suggest themselves, but with all the goodness of ginger (values, science)
that is
primarily used to prevent and relieve nausea, indigestion, heart rhythm irregularities, inflammation and pain. In patients with autoimmune disease, ginger is widely used to reduce arthritic symptoms, inflammation related to ulcerative colitis, and digestive disturbances. Ginger is also reported to lower cholesterol levels, inhibit replication of herpes simplex virus, and help prevent the formation of blood clots.

Add in the zing of the healing cayenne pepper and the fresh tartness of the powerful lemon against the sweetness of the honey, well it'll clean your pipes to be sure, and does have that satiating effect. I'm hoping to try this back home with manuka honey (the mystery of manuka - and more claims for its theraputic value). Indeed along with some other intriguing beverages, there's a manuka variant of this drink on a NZ wellness site. NZ is the home of that manuka bush that is the flower for this honey.

That recipe misses the pop of the cayenne and doesn't specify proportions. If one wanted a more intense experience - charleton heston seeing the face of god type intense - i'd contemplate simply adding in wasabi. Kenneth suggested one might also time travel with that combination. Which direction wasn't clear.

Anyway, recommended easy, fresh concoction for to have a go. Let me know what you find.

50% Lower cal MIXED carb with Moderate Protein better than Higher Carb alone for Greater Endurance

ResearchBlogging.org Want to stay out on your bike longer? There's a nice new study that has entered the energy drink fray, returning to the question of what's a ratio of protein to carbs that's optimal? In this case one measure of optimal is Time to Exhaustion or TTE. Also checked is optimal for what level of effort (below or near ventilatory threshold or VT). Turns out that half the calories (of the right blend of carb types with protein) can give greater, go longer, harder results.

The authors of this study manipulate a couple of variables in interesting ways. First, they decide they want to reduce the total amount of calories in the beverage - so lower the carbs in particular. But then, they want to look at a carb blend rather than just one carb type. So their target is a maltodextrin-dextrose-fructose blend. And then they want to add in some protein, since many studies have shown previously that throwing in some protein seems to have a better endurance effect than carb alone (a few recent examples cited below)

The authors say they were motivated by the desires of cyclists who actually want a lower cal beverage for restoration while on a ride. That makes the question simple: can a better blend of the basics achieve the same or better effect than a higher cal beverage for endurance?

That these authors are asking this question at two distinct ventelatory threshold percentages is also pretty unique.

Here's the abstract:
J Strength Cond Res. 2010 Oct;24(10):2577-86.
The effect of a low carbohydrate beverage with added protein on cycling endurance performance in trained athletes.

Abstract

Ingesting carbohydrate plus protein during prolonged variable intensity exercise has demonstrated improved aerobic endurance performance beyond that of a carbohydrate supplement alone. The purpose of the present study was to determine if a supplement containing a mixture of different carbohydrates (glucose, maltodextrin, and fructose) and a moderate amount of protein given during endurance exercise would increase time to exhaustion (TTE), despite containing 50% less total carbohydrate than a carbohydrate-only supplement. We also sought post priori to determine if there was a difference in effect based on percentage of ventilatory threshold (VT) at which the subjects cycled to exhaustion. Fifteen trained male and female cyclists exercised on 2 separate occasions at intensities alternating between 45 and 70% VO2max for 3 hours, after which the workload increased to ∼74-85% VO2max until exhaustion. Supplements (275 mL) were provided every 20 minutes during exercise, and these consisted of a 3% carbohydrate/1.2% protein supplement (MCP) and a 6% carbohydrate supplement (CHO). For the combined group (n = 15), TTE in MCP did not differ from CHO (31.06 ± 5.76 vs. 26.03 ± 4.27 minutes, respectively, p = 0.064). However, for subjects cycling at or below VT (n = 8), TTE in MCP was significantly greater than for CHO (45.64 ± 7.38 vs. 35.47 ± 5.94 minutes, respectively, p = 0.006). There were no significant differences in TTE for the above VT group (n = 7). Our results suggest that, compared to a traditional 6% CHO supplement, a mixture of carbohydrates plus a moderate amount of protein can improve aerobic endurance at exercise intensities near the VT, despite containing lower total carbohydrate and caloric content.
So, great, a lower cal (50% lower) blend of carbs and protein (about 2:1) of their mixed carb +pro beverage does just as well as a higher cal protein drink when  moseying along, BUT it kicks statistically significant butt when going near or at VT.

What's rather interesting to me is not only the lower calories but the carb/protein ratio. Previously, it was asserted that a 4 to 1 ratio of carbs to protein was best for endurance types doing post exercise recovery. Now, these folks aren't really assessing recovery; they're looking at being able to go longer and greater intensity on the bike. And for that a 2:1 ratio of their mixed carb blend is doing the job.

There was speculation back in a 2009 chocolate milk study (thomas09) that checking similar markers, the reason that choclate milk and just plain carb (gatorade) beverage did better than a 4:1 custom drink (endurox) is that chocolate milk has a diverse mix of carbs. Indeed, the authors site another relatively recent study  by Currell  and Jeukendrup (currell08) that looked at the role of blending carb types and saw an 8% boost in using blended rather than single source carbs for cycling time trials. Similarly a carb/protein blend seems to mean better muscle protection (saunders07).

So, that's good evidence to say let's just go with a blend rather than re-validating that carb blends are better.

One might ask why there were only two treatment conditions in the study: a CHO only drink at 6%, a mixed carb plus protein drink at half the calories. What about the mixed carb drink at half the calories, since we see from related research that mixed is better than straight carbs? The researchers had already done the related studies. They state:
Martinez-Lagunas et al.  recently compared the effects of a 4.5% CHO plus 1.15% PRO, and a 3% CHO plus 0.75% PRO beverage, to a traditional 6% CHO beverage and found that there was no difference in the times to exhaustion between the treatments. This suggests that the efficacy of the supplements was maintained despite the reduction in total CHO and total energy content with the substitution of a small amount of protein (ml). Based on these findings, we sought to determine if a lower CHO, lower calorie beverage containing a moderate amount of protein could be optimized using a mixture of CHO sources (glucose [dextrose], maltodextrin, and fructose) rather than a single CHO (dextrose).
Another nice thing about the study is that the researchers used trained athletes, which means that we're not having to account for level of fitness as a variable.  Even food logs for the three days leading up to the trial were assessed. The finding - 50% fewer calories  - for extended time to exhaustion when working hard is compelling. As the authors note:
The present investigation demonstrates that consuming a beverage containing a mixture of different carbohydrates, a moderate amount of protein and fewer calories than a traditional, higher single-carbohydrate supplement during endurance exercise can extend exercise TTE, especially when exercising at or below the VT.
Sometimes less really is more.

Unpacking a mystery: when shoulder pain may be all (or largely) in the wrist (a t-phase assessment story)

Pavel tells the joke about asking people in a weight room "so those of you who have had a shoulder injury, raise your hands" - half the people raise their hands; the other half can't.

Various types of shoulder issues are super common, and the usual go-to place is that the cause must be a rotator cuff tendon issue. But at least in my case, turns out it may be something very different: a muscle imbalance. That is, some muscles getting overworked with others getting underworked, resulting in other muscles not doing their jobs, and other muscles and associated tendons getting a bit worn out from having to do another muscle's job to pick up the slack. What's remarkable is how much immediate relief there can be once this issue is identified and actively addressed. So this is a bit of a story of unpacking that mystery through a lens that says always remember the site of pain mayn't be the source of pain.

Personal Case Study
A while ago i did a few posts about the latest work on tendonopathies and healing them, and a festival of posts on the amazing shoulder as a system in the body ( shoulder girdle part 1, gleno-humeral joint part 2), and then there was one about stopping reps in a set before they stopped us. These posts were largely motviated by my ongoing ache in my arm/shoulder. And i must say i was getting just a wee bit frustrated that i wasn't getting anywhere. This is the story of finally getting somewhere.


In the beginning: Seeing the MD. back in may/june the doc i first saw when my pain was at peak suggested what i had was a supraspinatus (top rotator cuff muscle) tendinitis. Ok.

Now i'm studying anatomy, and from what i could tell, all that muscle does is assist lifting the arm up to the side (like making airplane wings with ones arms). The things that hurt however were putting my coat on, when the arm reaches back to stick the arm into the jacket, and then when going the entire other way - crossing arms over to pull off a sweater. Ok, so maybe that's from a puffy supraspinatus getting jammed into the acromium of the shoulder (shown right) when the arm extends or internally rotates when abducting (emptying a pitcher). That seems pretty classic. And a week's worth of nsaids DID let me put my coat on again. So there seems to have been something going on there. But that wasn't all. Cuz it still hurt.

The Post MD Analysis, July 2010
In July, i'd asked a very competent movement scholar and chiropractic student to take a look at me, and we were rather flumoxed. He got as far as suggesting, based on loads of assessments, that perhaps it was lower trap related as doing some lower trap work seemed to bring some relief - he suggested that i spend some time with some drills focusing on lower trap work from Secrets of the Shoulder, which i did.

Time Passes - things shift/get worse. Intriguingly,  the pain changed, but did not go away; my strength progress was bottoming out. My press was not only totally buggered on the left, the pain was getting triggered when doing my right press. Not good for a gal who wants to press a 24kg kettlebell for reps.

The other thing? Where it really seemed to hurt was at the top-ish of the arm. And then the pain radiated down into the biceps. Maybe supraspinatus pain refers into the arm, i wondered.


But here's another thing: both the insertion of the supraspinatus (the attachment point furthest away from the middle of the body) and the origin of the long head biceps tendon (the attachment point of the muscle closest to the middle of the body) are very close to each other.  The supraspinatus inserts at the superior facet of greater tubercle (or tuberosity) of the humerus (at the top of the upper arm bone).  The long head of the biceps brachii passes over a notch in the humerus to attach to the supraglenoid tubercle - a part of the surface of the scapula that the humerus abuts in the shoulder.

In other words the two tendons are almost right on top of each other, and both connect with with the upper arm/scapula, so if one's sore, perhaps the other is going to bloody feel it, too? Or perhaps they'll just be hard to discern from each other.
Why is this identification of tendon proximity important? It's going to play a role shortly.

Indeed, reading about biceps tendinitis certainly seems similar to "overhead overuse" injuries for the supraspinatus rotator cuff. Reading about it also sounds pretty dam fatal: wear and tear; doom and gloom.  And strengthening the the biceps doesn't seem to be the winner here.


So what we have here is pain in shoulder extension and external rotation and pain in shoulder flexion, adduction and internal rotation. Yuck. Easier to stay naked than put clothes on or off, but not functional, and not helpful athletically. Playing frisbee all summer was a great way mainly to keep my shoulder mobile-ish without load, but i more or less had to forget about my 24kg press work.

The Analysis Redux, Oct 2010
Now we come to the latest analysis this past week with a very experienced z-health movement performance specialist whom i'd been waiting to have an opportunity to see. 1st, we went over the issue,  reviewing a detailed history (any stomach upset? any elbow issues? any neck pain? etc). Second, there was a look/test of some muscles between left and right sides.

What i had noticed only recently came to view here: my posterior delt was not firing fully - lots of squishy bits in it - compared to how well the right side was firing, the left lower posterior delt was like a deflated tire. That can't be good. Indeed see this post on muscle firing through the whole of the muscle for more. From here,  we started to Assume the Postion(s) - the Positions of Pain and test these.

Assessment Process, close up. After setting some global baselines, we moved through many of the muscles of the shoulder, either offering them an assist or taking them out of the equation to see what helped or did not through those movements. By this careful process of elimination, we got down to a few interesting findings:

1) pain in the biceps: there's that biceps tendon going into the shoulder - address that, and guess what - pain HUGELY reduced.
2) help out the brachioradialis/extensors (esp carpi radialis perhaps) overlapping tendon/musle area, there's more relief (nerve work for the radial nerve included).
3) muscle test some of those extensors and there's squishy bits - get that fixed so the whole extensor is firing, more relief.
4) pay attention to the axilary nerve that fires the deltoids, and the posterior delt starts to come back on line (have some more work to do there but heck it's work i know how to do).
5) do a wee bit of hybrid minimal t-phase style kinesio taping around the long head bicpes tendon area,  matched up with active dynamic joint mobility drills for the shoulder, elbow and extensors, and things start to simmer down
6)  work out some of the fascial stickiness around the extenors with v.light hybrid t-phase fascial work
7) get some exercises for working the extensors in particular,

And ta da, muscles start to re-balance, pain be much more gone; i can press again.

How could this issue come to be?
It's often just a best guess with what causes anything, but one proferred explanation for my stuff especially with the wrist/finger extensors is that kettlebelling offers a lot of opportunities for loaded wrist/finger flexion, not so much for loaded wrist/finger extension work. As in anything, balance is important. So who knows? Perhaps when doing a ton of double kb work, i pushed my less strong side to follow with my stronger side and things went sufficiently out of whack to build up an inflamation and ongoing pain.  This fits more of the facts than a supraspinatus diagnosis alone.

Rehab'ing
Beyond the above mentioned mobility and nerve drills, i'm doing some specific strength work. For the extensors i'm using two props: a mini jump stretch band with very light tension focusing on only enough load that i can get full to end range of motion wrist extension and wrist circles for the extension. I'm also using ironmind finger bands to practice finger extension reps. For mobility, i'm doing a lot of finger waves.


Master Class in Test/Re-assess. 
This whole suit of components listed above stemming from this assessment was very much for me a master class in what we learn in z-health t-phase (about z-health): take a great history; test and retest EACH step of an analysis (i haven't detailed all the stuff that was tested that did not get a result); apply one's understanding of muscle interaction, muscle function and nerve interaction; check function to bring it back on line; when locked in, apply dynamic joint mobility and loaded dynamic joint mobility as appropriate.

Test, re-test continuosly. Analysis is a process. And as things change/improve, retesting and refining in rehab remains important.

Analysis is also a process that follows where the path leads: despite the fact that this kind of pain is supposed to be indicative of a SITS/rotator cuff injury, it may not be. I'm also intrigued to learn about how the extensors relate to balancing the shoulder in rotation. Not something that seems obvious taking a shoulder-only focus. Likewise that working the area of the biceps tendon can be so impacted by rotation when it itself is not a rotator - makes sense looking at how rotation may stretch it, but again that's following the path and testing - and also having some faith. I *knew* i felt pain through the biceps, but just never conencted this with the biceps tendon.

A note on pain and perfromance: 
One of the effects of finding these muscle imbalances and nerve issues was an immediate and pretty signficiant improved range of motion. Like way - 15-20 degrees of extension in the shoulder that i didn't even know i had. 

What this experience reiterates for me is that pain is a performance signal; that having pain reduces performance, and perhaps especially that optimizing what we need for performance not only reduces that pain signal but also, as a connected process, opens up performance. The two are intimitaley and it seems inextricably related.

As i've suggested before, pain it seems is just another performance inhibitor indicator like tight muscles that restrict range of motion can be. When we take time to work with a movement performance coach to walk through the process, work the problem, both relief and performance pour in. I know this all intellectually - it makes sense in terms of what we know neurologically - but from time to time a demonstration of same is a pretty vital reminder of these issues.

In my case, the focus was on identifying performance issues: squishy muscle bits in extensors; impingement of some kind around muscles/tendons; looking at strategies to help bring performance back on line, lots of active work. Et voila: pain significantly reduced.



Coda It's only been a week since i've had this assessment but the performance improvment (and consequent pain reduction) is legion in comparison to what it's been. I'm being very gentle with working back into arm and shoulder strength work, but that i can get into these ranges of motion sans pain/ROM issues is pretty fab after months of pain/limitation.

What seems to have happened is that there is a path of unpacking/unwinding a problem going on towards addressing it. What is exciting to me is that the movement principles i've been studying for the past two and  a half years keep working - even for difficult cases. The nervous system is a remarkable thing.

It's rewarding to get to a place of really starting to see how the application of these principles continually opens up new opportunities to support healing without creating more pain first and with such immeidate effect.

Self-critique. I am also somewhat kicking myself for not working these patterns myself: nothing was really done in this assessment that i haven't been trained to do myself - that's the plus side. The down side is that i didn't take the time to work through this for myself. I remember moaning over the phone to one of the z-health master trainers how frustrated i'd been that i couldn't see a z-health solution to this problem, and his calm reply was "did you do all of the assessments"? i figured out that there were literally about 14 thousand possible combinations of assessments and that i guess i really hadn't.  It's a good thing we're not our own healers, and i'll say again, everyone needs a coach.

And one more time: analysis is an iterative process. Sometimes it will take more than one hour to get to the heart of a gnarly problem. In my case, it took two. Gosh. I'll also say that the confidence i have that this approach will help find a path through even gnarly performance problems elegantly has gone way up. As said, i see it in clients reguarly, but there's nothing like personal and direct experience to reenforce a value proposition, eh?
Personal Practice So suggestion? If you're having hinky performance/pain issues, check in with a movement performance specialist. Here's a trainer listing. If you'd like a referal, call the office, and let them know mc suggested you ask them.
Best with your practice,

Making the Ordinary Precious: revisiting the cup of coffee

The common practice/addictions often become common because they are accessible private or social pleasures around which we celebrate our days. What's problematic of course is when we're so wedded to such practices we can't seem to function without them. What's worse is when we find out that what we begin to call "functioning" isn't functioning - at least not optimally. Does that mean that these pleasures are evil? Can they be redeemed?

Recently, for example, i wrote about the effect of caffeine on our sleep quality. In sum, it can really really disrupt the restorative phase of sleep, the deep sleep cycle. Does that make coffee evil? 

At the time i wrote the above post, i was actually *really* tired, heading into the last leg of a long business road trip. The airline had lost my bag, didn't know where it was and i was sitting in a workshop with a colleague saying to me "i've never seen you look so tired." Super.

Normally, at times like this i would have fled to the nearest coffee pot and tried to jack up. It then occurred to me that perhaps what my body was telling me was that i needed some sleep, and wouldn't it be nice, rather than interfering with the quality of that process, i actually let myself *get* some sleep that evening. So i opted not to get the coffee. And i didn't touch any coffee for the next four days. Alas i didn't have my zeo on this trip to check the shifts in deep sleep cycle, but i know how i felt with a four day java break. What happened on day four?

The Best Cup.  When i was gigging my way through grad school, our band's drummer, Burt Harris, had a simple heuristic: no beer for the band till the last set break.

I was reminded of that on the last day of the workshop as  a colleague, Jen Waak, and i went for lunch and decided to go for coffee at the neighboring starbucks where i had whatever passes for a small latte. i asked them please (a) to make it with love and (b) not to scald the milk, as this was a precious, rare coffee. It was fabulous. For which i was really grateful since not all starbucks experiences are equivalently  dandy.

I know it had only been four days, but that coffee was *so* nice.

Considering how i'd felt getting my recovery back while not being on coffee, and how good that single latte tasted, well it got me thinking: maybe there are benefits to rare-ing out the common into the precious. That way perhaps even our simple pleasures can become exquisite ones - affordably, wonderfully, easily. 


Fave Places for Precious Blends? Please let me know if you've given such a strategy a go and how it's working. Also, if you have a fave non-chain coffee place - what is it and why is it a fave. For me, when i'm in Edinburgh around the eScience Center, i make a pilgrimage to Black Medicine. Awesome

ps:
my gratitude to Heidi Rothenburg for the zipfizz on that first day off the plane with no luggage and no sleep.

We're Walking Here - and feeling much better as a result: walking to rep in performance improvements

ResearchBlogging.org
Walking is an action most of us take for granted. It's such an automatic, effortless, thoughtless practice that we tend to forget it's actually a learned, practiced, skill. But it's this natural effortlessness of this deeply rep'ed & acquired practice that makes it so valuable for locking in better movement practice - what we practice when say working with a coach to tune dynamic joint movements (like those in z-health's R-Phase (overview) and  I-Phase (overview) drills) into our lives.

Indeed, walking is a huge component of Z-Health (overview). Folks familiar with Z-Health assessments know that they usually begin and end a session with a walk – and often walk in between various drills done within a session. But folks are also encouraged to walk on their own immediately after their own practice to help dial in the work they do during their session. It’s this part of the role of the walk ithat is the focus of this article, but to get at that part, we need to understand a little bit more about why the walk is so valuable in general.

Thoughtless Action – in a good way. Walking is a powerful communicator: it tells us a lot about our movement for a two key reasons we've touched on above: it’s autonomous, and its reflexive. Autonomous, from  the greek auto, means can act on its own. So we can walk while we do other things. Like chew gum and talk all at the same time.

Walking, as noted, is not innate; it is rather like riding a bicycle: a learned skill. Indeed, research shows two interesting things (at least) about this skill acquisition: (1) that when we begin to acquire the skill has been pretty steady for us for hundreds of millions of years (Garwicz09) but (2) that this motor skill acquisition is also affected by cultural practices (Karasik10).

Once we do get going, we learn and practice this skill millions of times (each step is a practice) it becomes not only autonomous but  reflexive. Reflexive means that the function moves from an act where we are thinking about it to something that is pre-cognitive – happens without having to think consciously about what to do. So with these two related qualities – autonomous and reflexive – we have an action that gives us a pretty good picture of how a person actually moves when they’re not thinking about it vs how a person may perform a less familiar action that requires their cognition and concentration.  Something that is, in effect, thoughtless, therefore seems to give us a more accurate picture of the quality of a person’s movement

From this picture of the walk, Z-Health practitioners starting at an R-Phase certification level (the first cert, overviewed here) have a repertoire of drills available to help address the performance issue identified. Kinaesthetically, the person themselves also get feedback from the walk: it’s not unusual for the person walking to volunteer comments at the end of a session like “that feels more open” or “that’s looser” or “something’s easier.” In this respect, the walk forms a kind of assessment/reality check for the person to see how all those little z-drills have had not only a local but a more systemic effect on their performance.

Loading Action More than just a self-check, because of its very systemic nature, walking is a great way to begin to enpattern (to coin a phrase) the better-ness being experienced in that self-check.
 In other words, our walking at the end of a session begins to practice the new way we are moving as a result of the drills we practiced to move better. By checking to see if we are moving better, rather ironically, when we are moving better (shown in the better walk), we are helping to practice the better-ness. That’s why if we’re not moving better after a drill and a re-walk, we keep working out more drills until there is a betterness. And then we practice betterness – not by doing the drills that helped open up the paths – or not them alone – but by putting the positive effect of the drill into a real and fundamental movement. Thereby improving the movement (which is what we care about really more than an isolated gesture) into a positive feedback loop.

Making Music vs Playing Scales Walking post session or for that matter after doing our own mobility practice is rather like after doing scales on an instrument, playing the real piece; the real piece benefits not because the piece is playing scales, but because the scales give us skills that are useful in playing real pieces – any piece - better. But then, the magic is likewise that by playing the tune with these enhanced skills, the tune playing is itself also practice of the specific movement – as a whole. Feedback loop. Thus drills give us skills that improve movement such as the very familiar autonomous walking, and walking itself with this practice makes walking better. That post-session walk-in is a rather Magic Walk that captures and integrates into the Real Movement the experience built from the (corrective) drills.

But wait! There’s more. This practice of engraining drill practice, as it were, within the real movement – translating the skills of the scales to enhancing the quality of the performance – that work itself changes the shape of the movement.

That change in the walk is a physical thing: those physical changes are effectively structural. Consider if to improve the walk, the walk shows us that ankle work may help; we do ankle drills; re-walk. Better. That improved movement in the ankle is practiced within the walk itself. Improved movement means improved function; improved function, with many reps, leads quickly to fundamentally enhanced structure. Thus function creates structure.

 This cycle of improving function to create improved structure occurs because we are plastic people. Woolf’s law demonstrates this effect with bone tissue (Frost01). Davis’s law shows this with our other tissues, like skin and fascia. And the SAID principle (specific adaptation to imposed demand) (Wallis & Logan) suggests this process of adaptation begins as soon as we introduce a demand upon the system. 

But wait! There’s Even More.

Keeping it Real; Keeping it Cool
Another aspect of the walk to dial in the drills we do for our performance improvement is that it may well also be neurologically soothing . The dynamic joint mobility drills in R-phase for instance help open up new signalling to the nervous system to say that a joint is moving better; a muscle is firing better and so we can move better.

To walk means to move. To move helps reduce stress (overview of why in 10 tips to de-stress); to move well means that a familiar, autonomous, reflexive act – something that therefore is in itself very low threat to the nervous system - is becoming better, easier, even less threatening – especially if there’s been any pain in the walk that’s lessened from our practice.. This better-ness amplifies all the positive benefits of movement. Easier, better, too, means less stress. We learn quickly from our body's responses that better movement means inner peace, happiness and perhaps improved prospects for a better incarnation: feeling better means easier to be nice rather than grumpy. And who wants to be grumpy and go to hell? Or reincarnate in a nasty place?

So we practice our drills, and then we walk them in. Beautiful music; beautiful movement.

PS - running and practicing running gait to reduce pain in running
Recent research (Noehren10) considered that gosh, knee pain in runners (Patellofemoral pain syndrome) seems to be connected to hip mechanics. The approach to address this problem was to wire up study participants not unlike the way folks are wired up to map computer animation to human movement. In this case markers were placed on areas of the hip, low back, knee, shin and foot.

Runners were then asked to run on a treadmill and look at their movement performance data against a Normal Curve (shown below). Participants were asked over the course of 8 sessions of running on a treadmill to get their movement curve (the white line) to match the normal curve of treadmill running (the white line in the grey band). The amount of feedback given was tailed off over time to see how well the training was being internalized. Participants were also retested a month after the trial to see if the new patterns had stuck.

 
While the results were not statistically significant (but very close to being so), they showed that hip mechanics did change/improve, and that most importantly, knee pain went down. The paper is free and worth reading.

From a neurological/SAID principle lens, there are a couple of points here. First, if someone is having hip issues, is that all that's going on? sometimes hip issues are the result of low back stuff, upper back stuff and in particular foot/ankle stuff. Focusing on the hip alone may be part of why the results in improvement were not significant. One might argue, though, that in order for the person to "move their curve" as shown above, perhaps they were also working on the ankle and back position issues to achieve the hip effect.

Second, running on a treadmill is a kind of weird thing relative to normal running or walking gait. When we run we choose our pace and stride length - it varries. On a treadmill, there's not much room for those subtle variations; the vestibular/visual dissonance also seems to create a performance hit vs land running/walking (ever feel a bit dizzy coming off a treadmill?)

Third of course, these folks all seem to be running with squishy largely not bendy heal-striking shoes. How about just thinking about getting out of those shoes or perhaps learning to get up into more natural/barefoot running type gait??

So what i wonder to myself is that if some of these folks with knee pain had come to see a Z-Health person with even just an R-Phase cert under their belts, and they'd been asked by said Zed folks to go for a walk (rather than step on a treadmill) to look at how they move at their own pace, in their own way, what might have been seen? Would a few reps with a few simple but very precicise R-Phase drills, followed by the Magic Post Session Walk have helped set up this better function sooner, faster, easier, and potentially have even greater benefit since the practice is located in the every day of the walk (using the SAID principle of specific adaptation) rather than the artifice of the treadmill? Just a question, but i'm guessing based on practice the answer is "uh huh."

And the beat goes on.
pps - if you're interested in the R-Phase cert, or in checking out zed (via the essentials of elite performance dvd or course) here's more info about z-health and the approaches here; if you do decide to take a cert, please consider indicating you came in via mc (that's me). We don't get paid money for any referals, but we do get some money off our own continuing ed with zed. Which is cool. And appreciated.

Squish your Eyes - and Relax

A while ago over at iamgeekfit, i posted ten tips to destress - very much related to hormone responses and ph balance. Well, recently learned there's one more thing we can do to relax that's pretty durn neural: squish our eyes.  With little circles.

How do it? As eric cobb puts it, imagine you're picking up a grape (using all your fingers). Take that position to the eye and press/massage for about 30seconds.

Yes, closing eyes and massaging around the eye, pushing gently on the eyeball through the lid, will help calm us down based on something called the "oculocadiac reflex"

In other words, the eyes, via a big nerve group in the head/face (the trigeminal nerve) are connected to this great big vagus nerve; the vagus nerve goes through touching our heart, our lungs and importantly our guts.

Doing a little eye squishing massage will help trigger the calming wonder that is the provinence of the valgus nerve.

If you dig these kind of tips there's way more eyeball wonderfulness covered in the Complete Athlete Vol 1 DVD. Turns out our eyes are important for more than vision.

Doing eye squishing daily - may make more of a difference than just feeling relaxed. If you give it a go for two weeks, daily, please let me know what you notice changes in your well being/performance.

Caffeine makes us Crazy - or at least messes with our sleep

ResearchBlogging.org i *love* good coffee. You? Do you know how you react to coffee? Do you find caffeine keeps you awake/alert? Yes? or maybe you find it doesn't affect your getting to sleep? We know that the magic in coffee is caffeine. Guess what? apparently whether or not we can fall asleep with caffeine is less of an issue than what it does to our sleep quality, in particular, our deep sleep state. That is, it screws it up.

So yes, we might be able to get to sleep (or not) with caffeine in our systems (caffeine genetics is cool), but once we are asleep - based on what's happening in our brain - we just mayn't have enough signaling in the presence of caffeine to tell us to get to DEEP sleep. Wild, eh?

So what's caffeine doing to us? There's a great detailed write up of the  chemistry of caffeine and the brain (calmly titled "Is caffeine a health hazard?") by Ben Best. If i can summarise that article without wrecking it, here's the simplified version, and it's so cool, it just makes sense.

Energy. All or our systems require ATP to do work. Adenosine Triphosphate. Folks into performance are v. familiar with ATP in terms of energy system work, and how Fat for instance is our biggest but slowest generating source of ATP. ATP produces energy by being broken apart into two parts: adenosine  and adenosinediphosphate. The work of energy production is a cycle of putting a and adp together again to from new ATP.

Fatigue. Fatigue is a really interesting process. All we're going to look at here is one tiny tiny bit. When we get fatigued and need rest, the adenosine that gets generated from ATP being broken down, rather than being reassembled into new ATP actually just builds up around the cells and doesn't get used. That's a really good thing. Adenosine on it's one is a brain signaller. As adenosine builds up in this fluid around the cells a bunch of things happen, including effectively signaling the brain to shift down, and when asleep to fasciliate deep, slow wave sleep. As the presence of adenosine goes up, brain wave activity goes down, deep sleep can happen.


Caffeine the Disruptor. An amazing property of caffiene is that it is a Master of Disguise. It connects with adenosine receptors (getting across the blood brain barrier) so that adenosine can't get to those receptors (A1 in particular), and effectively means that the brain doesn't perceive the degree of adenosine build up, and so the signaling to slow the heck down can't happen. All sorts of tests show that with caffeine folks do better in various kinds of tasks, and has been tested with soldiers and athletes rather a lot. But even more recently with soldiers, there's an effort to get away from "stimulants" and think more about scheduling.

Bottom line is that caffeine a way to fake out our system into believing its less tired than it is. There are costs. It's pretty easy to see that while coffee'ing up will give most of us a jolt, we're still actually fatigued, and we are artificially asking our bodies to work beyond what they require for optimal function.

The effects are at least in two ways:

  1. compromised deep sleep quality means our recovery is compromised, and if as athletes we're trying to build physical function, deep sleep is where that building takes place, so we've just screwed the efficacy of our build phase; 
  2. because we're actually still fatigued, and not getting sleep, sleep deprivation effects kick in. Stress goes up, fucntion goes down, ability even to process food, have sex, do anything gets screwed up. Irony eh? we take caffeine to perk up and it ends up actually screwing up our sleep recovery.

The other thing is that caffeine can actually take awhile to flush from our systems. Yesterday in talking about the value of darkness at night for sleep quality, i mentioned zeo as a tool to see how one's sleep quality changes. We use zeo in our lab for "self-monitoring." We can see that deep sleep quality seems to stay effected for days after even with single doses of caffeine. Bummer.

As zeo sleep researcher Stephan Fabregas has said previously at b2d, using caffeine in extremis for the occaision we need it, it can be great and useful. As a regular practice, maybe not so good. Bummer again. But that turns out to be the same for athletes using caffeine to help perk performance too.

The worst part of caffeine apparently is coming off it. Get through that, and sleep gets better, and we need caffeine less. How about that?

Break the cycle (of dependence); improve sleep quality, improve recovery and quality of life.

If you are a big starbucks mega coffee drinker, and you try going from Really Big to Not Quite So Big to maybe one less a day, let me know if you notice a difference over time of being on less or none of the stuff.

Good luck on your caffeine control mission.

Cover your eyes - better sleep in one night

Here's a very very simple thing you can do to get a better night's sleep. Really. Seriously: eye covers.

If you do not have a totally dark, pitch black room to sleep in - and i mean any fricking electrical light - then consider giving eye covers a go.  You may *think* you have a dark room, but if you can see your hand easily when the lights are off, maybe not.

Why is total darkness important? My understanding from Zeo Sleep Research Stephan Fabregas is it's hormonal: darkness triggers melatonin to come on which helps put us nighty night. Any light starts to tell melotonin to turn off the hormonal pipe to la la land and that means we start to wake up.

In my personal experience with the eye covers - especially in the summer when i have not wanted to get up with the sun - i have found that using these covers means that i sleep longer, better, deeper with less wakeful states. How do i know this? besides how i feel, i do use a Zeo to track my sleep (discussed here and here with Stephan), so i know. Yes i'm the type of person that if someone asks "how did you sleep" - i check the zeo.

ANYWAY cheap experiment: try a few nights without; a few nights (give yourself a chance to get used to the eye patches), and see if you feel more rested avec le mask. Let me know how it goes. Expecially travelling, this thing is a life saver.

Here's to your better night's sleep, fast.

Vibram FiveFingers Smartwool Classic for Warmer Winter Toes (preview)

UPPER - SmartWool Cozy with
67% Merino Wool, 33% Nylon
SOLE- EcoStep 2 rubber with 50% recycled content
FOOTBED- SmartWool Felt 2mm with
95% Merino Wool, 5%Polyester
My feet turn blue even on summer evenings. Doesn't bother me. Much. I like going barefoot, and socks just mean slipping on wood and tile floors in the house. But it would be nice to be less blue of foot. I think vibram may have developed a solution: make their classic slipper like version with smartwool upper and felt liner. Voila, the smartwool classic. So here's a wee preview of this new vff, with a few notes on fit.

Wool: it's lovely Now i dig smartwool as a company. It uses marino wool for everything from toques to socks. I love my smartwool toque that i got in Santa Fe nearing on 10 years ago. Durable without looking aged (ie, ratty) and very cozy.  The shoes have the same sort of feel. In fact the feel very soothing just stepping into them. Performance, but with an emphasis on the kind of comfort only wool brings.

Recycled Sole Another thing about the shoe that's interesting is that the sole is 50% recycled rubber.  That's nice.

Pull Tab. And i dunno why but i can actually use the pull tab elastic on this version of the classic and not feel it biting into my ankle. Many folks actually cut the cord as it were when using classics because of this. For some reason, - maybe the back rubber behind the pull is a bit thicker - it's a functional device on these ones.

Testing Fit. I'm happy to trial these out - i had hoped for a similar result with the performa, but that shoe and i just haven't been a strong and happy mix. Not that that driver's glove for one's feet that the performa/moc is, is not a lovely shoe; the fit just didn't come together perfectly for me. But my cousin now loves me even more for having passed them on to her. So i'm hoping the smartwools that i have on right now will work - the toasty feeling in this cool room is just what i've been seeking.

The Longer Toe Issue: Where's the hesitancy in my voice? Fit. The smartwool is the same sizing as the the classics. That said it's not the exact same fit. Speaking with the kind folks at City Sports in Boston about the differences, Alison said "It's the big toe, isn't it?" yes, i said, exactly. The big toe (sorta like the performas were). You may find that where you usually have some extra room on a regular classic, ya just don't in the smartwool - especially if you are sizing from a longer than big toe toe. If you order these online, be sure to check your vendor's return policy as you might want to get your usual classic and one up to make sure.  These are wool uppers: they're going to stretch, that's true. But they'll stretch wide, not long.


Now when i one upped the size with the performa for the toes to fit better, the rest of the foot was just too loose. Hence the gift to cousin. For those of us with longer than big toe toes - this shoe  (like the performa) *may not work*  But that may depend as well on just how much longer the toe is: the one on my left is not as much longer than the one on the right, and the left feels perfect, beautiful, lovely. But the right foot is likely bigger than the left, too along with the longer toe, and it is both the big toe and the longer toe where - all i can say is i'm "aware" of those toes.  Will this sensation go away? i don't know.

With no other VFF to date have i had any issues with toe sizing. The bikilas (my huge concrete running, good looking fave) are just awesome. KSO's same thing. Sprints, yes. Standard classics fine, flow, fine. What's with the revised classics (performan/smartwools) that the toes feel a little - well - something.

It was a show stopper on the performa; don't know if it will be here.

And here's the other weirdness: i have put the soles of these smartwools right up against the standard classics and matched them groove against groove. THey are - as far as i can tell - exactly the same length on everything. So how weird is that?? I just know when i put on the regular classics i have no toe awarenes on the right - indeed i can squish the big toe cap a bit - there's room at the top of the toe; put on the smartwools - no squish and toe awareness. Will it go away?? Or will these shoes just go back?

And here's the funny thing: wearing socks feels pretty good too! Dunno what's going on. These are wild and crazy shoes.

UPDATE - le recherche: well, after wearing them back and forth indoors for hours, testing with and without socks, alas that right foot shoe feels like it's just not making happy with both the big toe and the long toe, so i've had to return them. Sigh. Just like the performa. I'll try to find out why these fit differerntly than the other classics.

Recommendation:  for folks with no toe issues looking for a cozier shoe for kicking back at home - or just something kinda funkier for dress wear - these are a goodie.

PS - the Sport Trek - quick overivew
Also tried on a TrekSport today. Maybe it was the black, but i just didn't go for it. Here's why: it has a KSO'ish upper (tho different material - still mesh) and the trek's sole. That may be perfect for hiking about in the summer - the mesh is really really nice on these - but coming into the fall, i'm not sure they'd be a much used shoe.

Here's the thing. The bikila's (discussed here) have become my fave running-on-concrete/frisbee playing/looking fine shoe. I really LOVE these shoes (tho they sure pick up a stink more than any of the other VFFs. Wow).

Compared with the KSO, the kso have a 2mm insole and a 3.5 mm outsole. The Bikilas have just a wee bit more sculted love with a 3mm insole and 4mm "anatomical pod" outsole. That's just about as thick as i want to go for what i do in the city and on the grass. The advantage of the slight treading on the grass is that unlike the standard vff soles, these do not slip about. Nice effect for stop and start movement.

Now the TrekSport has a 4mm eva midsole and a 4mm outsole with the nobly tread. I feel like i noticed that extra thickness. And again, for what i do, not needed. If i were living close to a trail and running in the woods in warm/hot weather, these would likely ROCK.

In the interim, i am still keen to try a woman's KSO Trek for fall/winter - just for foot warmth - to extend outdoor season. And the lovely thin SportTrek Uppers just won't do that.

Aren't all these new models wild?

Anyway there's new good stuff (and familiar stuff) at Vibram FiveFingers. Hope you'll check it out.

FIT in general
And if you're keen to learn how to fit these things, and what they fit like with sock, here's an overview, and here's a way to test any shoes for foot health. PLUS a whole lot more articules on the VFF experience over - gosh - approaching two years of living in VFF's.

The fine art of the Nudge - optimizing exercise to support body comp change - the more of less

Have you heard this one or perhaps felt this way "I work out and then i feel so sore the next day, i just don't feel like doing it again." I've heard this response frequently this past week when putting together some research strategies with tech experts on the subject of wellbeing.

It's interesting to explore why most of us who don't currently work out or do so infrequently feel we have to work until we need a bucket for the experience to have value. The weird thing is that when asked, we don't necessarily have a reply. Isn't that what we're supposed to do? Turn on the TV and see ads for 6 or 12 week programs where the goal is by the end of the workout to collapse in a puddle, one might think that that was indeed the case (i've written before about some issues with these approaches).


All we need is (a) Nudge Dan John talks about just needing to "nudge" our workouts to get exceptional returns in strength . I'd suggest that we see value in applying that approach across the board for well being. Why? It turns out that the way we're wired, nudging our progress may be more effective and beneficial for the long haul that anything else - body comp changes included.  So let's look a little bit at this exercise myth of working out "hard" vs working out "well"

UnFit Myth #1 for Body Comp Change: Non Stop Intensity

1) Have to work out "really hard" - to the point of collapse from fatigue to get results (but i hate how i feel the next day).

Let's assume results mean burning fat, dropping fat mass. What does all this frenetic activity mean? If we're just getting into working out, fatigue comes from a lot of places. First of all, our bodies haven't adapted to the demands of working out. We get "gassed"  or "winded" No kidding. We just don't have the capacity in our bodies - yet - to work out either long or hard.  We run out of available energy.  Literally.

A Nudge is All that's Required
SO what's the point of exercise? It's to engage and extend a process of change; it's all the words ending in  "-er." Like go fast-er, lift strong-er, run long-er, jump high-er. Exercise is literally *changing* us as our bodies adapt to the new loads. Let's consider a few of the changes that occur

Breathing For instance, when we're out for a light run and our hearts are at about 60% of whatever their 100% capacity to beat in a minute is, but we still feel initially like that's pretty taxing - we can only do it for a few minutes at a time - here's part of what our bodies are doing: they're creating MORE of a particular part of our cell - the mitochondria - that chews fat and turns it into energy. More mitochondria means that we can take more fat in and convert it into energy so we can keep going. That's great.

Muscle Likewise when we lift weights - also really great for body comp - if the load is even a bit of a challenge for us - we do even a few reps, regularly, our very muscles change. The theory (sliding filament) goes that they have components that almost like a tug of war that grab onto each other and pull to contract or the muscle. This growth is part of why, over time, we get stronger; the once heavy weight feels lighter.


Learning/Nervous system One more really critical change is in our wiring. When we do anything physically, we are learning how to do it; our muscles are likewise learning how to perform a particular technique. When we feel ourselves shaking when we hold a new posture that's usually our nervous system rapidly trying to figure out in this new move what muscles need to fire when to support this movement. Repetitions are really important for that.


Enter the Nudge
What Do We Need For Adaptation?
Some of us think we exercise to lose weight. Fair enough. That's almost another myth though. Exercise isn't really about weight loss. It's actually a secondary component to diet - how much that component contributes to  fat burning really depends on how much we do, and somewhat on what kind of work we do when we're doing it.

The primary effect of exercise is to help us become more robust, and, as i've pointed to before, become smarter (another "-er) as well. Seriously. This bullet proofing occurs by pushing our system to adapt, to make those changes described above, to support what we're doing while being less taxing.

That's an important point for us to get: we need to do something in such a way that our bodies need to change to support that demand physiologically and neurologically.

Just Enough.
So our bodies can only change so much physiologically at once. Figuring out that amount is part of an ongoing debate, but one of the toughest things for many people to get is that usually what we actually need to do to promote an adaptation is a lot less than we think. A. Lot. Less.

But what does less mean? Less can happen over
  • time: how long an action is carried out - like the length of a workout
  • volume how much work is done within that time - volume of something
  • intensity how much effort the work takes, or how heavy a load is relative to how much one can lift once
So we can vary any of these components. Some programs have folks working  for long workouts (over an hour), for medium to high effort (intensity) for many sets (volume).

Some workouts focus on taking a long time to lift heavy loads (intensity) 2 or 3 times (volume), taking a long time (5 minutes or more) between doing maybe five sets (volume) .

Each of these approaches does different things to the body and each has particular costs. From the long, intense, multi-set workout, people feel fatigued and also often sore. Intriguingly the heavy workouts with few reps, few sets and long rest breaks can have very similar effects without inducing fatigue.

What's going on?  Muscle Fibers and Oxidative capacity
Without going into a lot of detai, there's two things at least at play in getting body comp change without killing oneself
- aerobic adaptation - more mitochondria
- muscle fiber type - hitting the sweet spot for muscle response

Aerobic Adaptation By doing ANYTHING that will elevate our hearts above 60% of max - the classic working hard but can still carry on a conversation - we are causing a performance related adapatation to take place in our bodies - we are causing more mitochondria to get built so that more fat can be utilized to produce more energy to keep us going longer and harder without putting us in the ground.

Muscular Adaptation The main thing about adaptation is that we need to keep nudging our current state. That may mean one day if out for a run, going a few seconds longer or a wee bit harder for a little bit, a few times throughout the run. That means in lifting we might use waves of loads so that in a week we have a lighter, medium and heavy day with what we're doing - doing the same lifts each day. As long as there's a *bit* of a challenge, and adaptation occurs. There are many ways to do this kind of waving of loads, but the main thing is that by waving the loads we challenge our muscle fibers to have to respond to get stronger so that we can do more - and doing more also requires more energy, which means more fuel gets burned.

Recovery - the Sweet Spot of Adaptation. If we are fatigued and can't rest, our efforts can go for not because our recovery sucks. So, one way to ensure great adapatation is to go just to the place of getting that adaptation demand - the nudge on our current level - and getting good rest since it's in the recovery that the adaptation occurs - while our bodies figure out what they need to do to support loads like we've given them

Food - optimizing fuel intake
Another aspect of suppoprting exercise is fuel. Just because we have fat to burn for fuel, doesn't mean that we don't need to eat. There's stuff we need every day in our bodies to be efficient. In fact it's sometimes harder to burn fuel without the presence of food. But again what we need is usually less than we think - but less of the right stuff. Precision Nutrition makes figuring out what when very easy with its habits based approaches. Here's a free overview.

Take Away: Less of the Right Work =  More of the Right results
So the point of exercise is to create an adaptation in the body: to help it become progressively more robust, and a better burner of fuel (fat in particular) to become that lean mean machine.

The main thing is - and this is what's really hard to get - is that adaptation can be, to use Dan John's phrasing "nudged" - in fact it's better for us to nudge the adaptation than to try to crush ourselves. Why? our nervous system can get really stressed if every workout is super intense. Ironically, working out like that can make us sick.

This doesn't mean we can't work out hard. It means we don't have to workout THAT hard ALL the time. That means deliberately backing off in order to gain more strength, gain more adapatation.

We'll come back another time to examples of such approaches, but the point is that gains will happen consistently effectively and too easily for anyone to believe in terms of strength and aerobic capacity.

DIET: Combine this nudging approach with good nutrition practices, like Precision Nutrition, and you're away.

TIME
One thing that seems to have the best effect is daily practice: find a way to do something every day.

The people who are most happy with their body comp it seems, seem to be doing something that is causing an adaptation for at least 5 hours a week. This 5 hour approache includes anything that is getting the heart rate up for five hours a week.

We can Play frisbee or five a side football (rated most effective for ex-coach potatoes) with our pals for a couple hours a week; lift some weights (go ligher than you think - half the load you can lift once); push some weights; pull some weights; swing some weights pretty much every day when it's something that's not going to kill us.  THere are loads of great programs available. Sources i trust and have written about here are by Pavel Tsatsouline and Dan John because on the weights side, they are masters of the Nudge. Indeed take a look at the record setting results Dan got with Pavel's 40 day way less is way more approach. Look as well at how Asha Wagner got tremendous strength PR's practicing with half the loads she would use in competition.

On the cardio/endurance side, i like a mix of steady state, play, and intervals. There's nice research on how to optimize fat burning outside intervals and within intervals.But again, these can all be achieved in a huge variety of ways that enhance well being, sense of joy and more robust us-ness.

Summing Up
Adaptation. That's what exercise is about. So we really do need to be kind to ourselves. We adapt readily; it's how we're wired. We adapt to change best and for the long haul it seems by Nudging. So do something that gets the heart up more of the time; super intensity being valuable, but less of the time. This way we can always urge the nudge on. Last month the nudge meant i lifted X; this month it's X+y. THat y might be more sets; more load; more time.

Killing ourselves to feel better? Not on. In fact, it's counter productive. Sure we can do it for three months but the cost on day 91 isn't often pretty. And then what on day 92?

Good Exercise Practice is about sustained adaptation towards a better, stronger, leaner us. That better is better when it's a Nudge: progressive, allows for excellent recovery and is accompanied by good nutrition habits.
