Protein reduces endurance (in mice), food processing vs food refining & Schrödinger.

I saw the following study via Twitter. Dietary protein decreases exercise endurance through rapamycin-sensitive suppression of muscle mitochondria.
Mmm, protein!
Hmmm! In mice, a high protein diet significantly decreased the amount of muscle mitochondria, the mitochondrial activity and the running distance at 50 weeks, although it increased muscle mass and grip power.

A mouse's natural diet is fruit or grain from plants, though mice will eat virtually anything, including Kevlar insulation on wiring. Fruit & grains aren't particularly high in protein, so it's quite possible that eating a sub-optimal diet results in sub-optimal health.

If the results do translate to humans, we have a choice between endurance, and muscle mass & strength in our old-age. I know which I would choose. You'll have to prise the proteins from my cold, dead fingers!

More from Twitter:  A Major Communication Challenge of Our Times: What on Earth Do We Say About Processed Foods? The word "refine/refined" doesn't appear in the above article. I don't have a problem with food processing. What I do have a problem with is food refining. Just after the Mid-Victorian period, it became fashionable to eat foods that had been stripped of "impurities". Goodbye essential co-factors. Hello, degenerative diseases.

Finally, today is the 126th anniversary of Erwin Schrödinger's birthday. I have only one comment:-

Strength and insulin resistance

In all the discussions about how different diets may or may not promote insulin resistance, one thing that often gets missed out of the discussion is the role of the muscles.  Empty the muscles of glycogen through hard exercise and they will get more insulin sensitive to suck up the sugar out of the blood.  (Nigel has been trying to explain this but that is a different topic)

It is something that I talk about in Hillfit as a side benefit of strength training and an issue that Doug McGuff and John Little go into in Body by Science. 

Anyway, interesting to see this study come through this morning - at least some association between strength levels and markers of insulin sensitivity

Muscular strength and markers of insulin resistance in European adolescents: the HELENA Study

The aim of the study was to examine the association of muscular strength with markers of insulin resistance in European adolescents. The study comprised a total of 1,053 adolescents (499 males; 12.5–17.5 years) from ten European cities participating in the Healthy Lifestyle in Europe by Nutrition in Adolescence (HELENA) Cross-Sectional Study. Muscular strength was measured by the handgrip strength and standing long jump tests. Cardiorespiratory fitness was measured by the 20-m shuttle run test. Fasting insulin and glucose were measured and the homeostasis model assessment (HOMA) and quantitative insulin sensitivity check index (QUICKI) indices were calculated. Weight, height, waist circumference and skinfold thickness were measured, and body mass index (BMI) was calculated. In males, the handgrip strength and standing long jump tests were negatively associated with fasting insulin and HOMA (all P < 0.05) after controlling for pubertal status, country and BMI or waist circumference. When skinfold thickness was included in the model, the association became non-significant. In females, the standing long jump test was negatively associated with fasting insulin and HOMA (all P < 0.001) after controlling for pubertal status, country and surrogate markers of total or central body fat (BMI, waist circumference or skinfold thickness). Findings were retained in males, but not in females after controlling for cardiorespiratory fitness. The findings of the present study suggest that preventive strategies should focus not only on decreasing fatness and increasing cardiorespiratory fitness but also on enhancing muscular strength.

7 Psychological Reasons Why Experts will always argue

This is a guest post from Coach Nick Tumminello has built a reputation as the ‘Trainer of trainers” through his workshops at conferences and fitness club around the world. And, for his consulting work with pro/college sports teams and with exercise equipment/ clothing manufactures.
He’s the owner of Performance University international, which provides hybrid strength training & conditioning for athletes and educational programs for fitness professionals. Based in South Florida, Nick is a Fort Lauderdale personal trainer who works with a select group of athletes and exercise enthusiasts.

You can check out Coach Nick’s articles, DVDs, seminars schedule, mentorship program and very popular hybrid fitness training blog at http://nicktumminello.com/


7 Psychological Reasons Why Experts will always argue; Training Debates are a waste; and the Fitness industry will stay divided.


 I often get asked why I don’t express my feelings about what other coaches are doing/saying, or why I no longer get involved in training debates with other coaches or on the fitness forums? My answer is always the same: “Because I now have a better understanding of human psychology.”  I then follow that answer with this advice, “if you’re asking me this because you’re hoping for someone to actually “win” one of these training arguments so you can finally have an answer. Or, you’re thinking that any of these highly debated training topics will soon reach a generally agreed upon consensus – get ready to die as a very confused and frustrated trainer… because those training arguments aren’t even about training to begin with. That’s why no one ever seems to change their mind even when their views are eroded by science. These debates aren’t about information, they’re about the mind games we’ve all played on ourselves and we don’t even know it.”

Turning A Negative into a Positive!


I know all this is sounding awfully negative. And, negativity just ain’t my style. But, this post isn’t about my usual innovative, solutions-based hybrid training concepts. Instead, it’s about  7 Psychological facts, which are an unavoidable part of human nature that, although negative in nature, we all must accept and work to better understand.

That said, the positive outcome is that becoming aware of and learning to embrace these factors has really helped me to better understand myself, my clients, my fellow colleques; and helped to to better maximize my time and mental energy in a more productive manner. And, I know they’ll do the same for you too. That is, if you’re willing to first embrace and address them within yourself before everyone else.

You’re about to discover why one of my favorite old punk-rock bands: The Descendents, were right on (back in the early 90s) with what they say in the beginning of their classic punk song Cool To Be You - “I don’t believe in unity. It’s just one more abandoned dream. Once the people get together it’s easy to see. It’s just a matter of time before they come after me.”


 Why Arguments About Training have Little to Do With Training

 Think about it! Have you ever seen a forum of facebook debate about training where one coach said “you know what, you’re right and I’m wrong – I’ll do it your way from now on.” Usually if something like that is said, its more likely said in a passive aggressive style because one person simply got sick of arguing.

Have you also noticed that in these debates people assume a great deal, often filling in the blanks and putting words in each other’s mouths? Or, coaches often seem to take the same rebuttal stance regardless of the challenging information that gets posed to them? Better yet, have you seen how trainers often take it personally and get all defensive when you simply show them scientific evidence that may have found results, which challenge they’re views, as if you just trash-talked their mother. I could go on, but you get the point!

The fact is, in theses coaches vs. coaches debates, both parties can present logical, rational and even scientifically backed evidence in favor of their thought process. Yet, often times, all involved end up calling the other “stupid” or accuse one another of using “flawed logic” and seem to end up personally not liking one another simply because they have different professional outlooks. How can this be?

How can so many passionate and motivated fitness professionals who all incorporate both science and common sense,  and who all have success still remain so separated and at opposite sides of the track?

These 7 Psychological Facts will explain why these on-going intra-industry issues have little (if anything) to with how we train. Instead, they have to do with how we think.

 1. Ad Hominem


According to David McRaney, author of You Are Not So Smart, “It’s a misconception that if you don’t trust someone, you should ignore their claims. The Truth is: What people say and why they say it should be judged separately.”  - “This knowledge is is based on the Ad Hominem fallacy. It comes into play when you judge people based on who they are, not what they have to say.” – “An Ad Hominem attack occurs when you criticize the person rather then their claims. It happens when, in the midst of a heated discussion, someone points a finger and say “You’re stupid!.”



McRaney adds, “You see it in politics all the time. if you can’t taint the character of a person, it’s easy to taint whatever he’s bringing to the table.”

Fitness Industry Example of an Ad Hominem: My great friends Bret Contreras and Brad Schoenfeld recently wrote a research review paper called To Crunch or Not to Crunch, which most have probably read by now.

Brad and Bret did not actually conduct any of the studies they provided in their paper. All they did in their paper was review the related scientific evidence and provide simple recommendations based on the science. But, those who felt the paper refuted their personal beliefs & biases fought back by taking personal pot-shots at Bret and Brad themselves… while basically ignoring the actual scientific evidence they provided.

When all you do is look at the people who simply put the information in one place for us to read, instead of looking at the information itself, it insults the researchers who actually did perform the studies. And, it directly undermines the scientific information gained from theses studies.

Heck, after the paper came out all you heard was Contreras vs. McGill. It wasn’t about information, it was about people. Then of course coaches said, I’ll go with McGill because Bret is younger and less experienced. That my friends is a glaring example of an Ad Hominem fallacy.

Judge the information for only what it is: INFORMATION… NOT the person or people providing it!

  2.  Illusory superiority



The generally used definition of Illusory superiority is a cognitive bias that causes people to overestimate their positive qualities and abilities and to underestimate their negative qualities, relative to others.



You may have heard the quote, “The average person thinks they aren’t.” Well, the science proves that to be true!

In a survey done at the University of Nebraska, 68% of the faculty rated themselves in the top 25% for teaching ability.(1)

In a another similar survey done at Stanford University, 87% of MBA students rated their academic performance as above the median. (2)

Paul C. Price, author of the paper Are You as Good a Teacher as You Think?, did a great job of describing  why teachers and coaches should understand Illusory superiority: ”Unfortunately, the most appropriate reaction—concern—is also the least likely, because people’s tendency to think of themselves as better than average extends to their ability to avoid such biases; “Sure other people overestimate their traits and abilities, but I would never do that.” See the problem? Concern is appropriate, however, because there is a great deal of evidence from social-cognitive psychology that pretty much anyone who isn’t clinically depressed systematically overestimates his or her own traits and abilities in a wide variety of domains. Furthermore, the nature of  teaching makes it especially prone to such overestimation for reasons that I describe in this paper. A second reason that we, as teachers, should be concerned by this result is that recognizing our shortcomings is a prerequisite for improvement and, perhaps surprisingly, can be tremendously motivating.”

 Fitness Industry Example of Illusionary Superiority: We all know that controversy gets attention. Well, there are two reasons one would create controversy: to get attention, or to provide new information that shows us we may need to change.

You’ll find the same coaches who accuse other trainers of creating controversy simply to get attention, are the very same ones who’ve created controversy themselves. That’s because they obviously believe that THEY caused a stir because they were smart enough to realize something everyone else had yet to uncover and they simply wanted to enlighten the rest of us. But, to them anyone else who challenges current beliefs has devious intentions because they’re not smart enough to find something the rest of us have yet to see. That is a great example of Illusionary superiority.

Note: The next 2 Psychological Factors on my list below are actually the two (out of 5) main mechanisms proposed by Alicke and Govorun (2005) (3), in attempt to explain why illusory superiority (which they refer to as the better-than-average effect) occurs. (The info for #3 & 4 has been taken directly from this Wikipedia page.)

3.  Selective recruitment


This is the idea that when making a comparison with a peer an individual will select their own strengths and the other’s weaknesses in order that they appear better on the whole.

Perloff and Fetzer (1986) suggested that when comparing themselves to an average peer on a particular ability or characteristic an individual would choose a comparison target (the peer being compared) that scored less well on that ability or characteristic, in order that the individual would appear to be better than average.

However these results are not completely reliable and could be affected by the fact that individuals like their close friends more than an “average peer” and may as a result rate their friend as being higher than average, therefore the friend would not be an objective comparison target.(4)

Fitness Industry Example of Selective recruitment: There are some many different training styles and systems in our industry. All of which have their strengths and weaknesses. Yet, many of the zealot members of these systems argue why THIER way is best and why their fellow members of the group “get it”, while others don’t. They like to bring to light the strengths of their system while focusing on the limitations of other’s systems.

4.  Egocentrism


This is the idea that an individual places greater importance and significance on their own abilities, characteristics and behaviors than those of others. Egocentrism is therefore a less overtly self-serving bias.



According to egocentrism, individuals will overestimate themselves in relation to others because they believe that they have an advantage that others do not have, as an individual considering their own performance and another’s performance will consider their performance to be better, even when they are in fact equal. Kruger (1999) (5)

Fitness Industry Example of egocentrism: Have you ever met a yoga instructor who has told you that you DON’T need yoga. How about a powerlifter who said that you were already strong enough. Or, a corrective specialist that told you that your posture was fine and that you had zero muscle imbalances or asymmetries? Or course not! That’s egocentrism at work!

Another example is that coaches often down other (younger) coaches of whom have less experience than they do. Interestingly, 5yr coaches say 2-3yr coaches don’t have enough experience. The 10yr veterans say the 5yr coaches aren’t experienced enough. The 20yr coaches say…

It always seems to be the # of years experience YOU have is the “optimal #” of experience. And, isn’t it funny that when someone has been in the game for a very longtime, much longer than us, we just call them a “dinosaur” who’s stuck doing things the “old” way.

5. Humans are Tribal oriented!




Just look at politics and you’ll see glaringly obvious example of how us humans are tribal oriented creatures. Put simply, we like to bond with like-minded folks. And, we like to make fun of the people (in other tribes) who don’t think like us.

The fitness training world is just like the political world. In that, we have the Kettlebell party (and various divisions of that), the Pilates Party, the Yoga Party, the Strength Party (and various division of that like bodybuilding, powerlifting, strongman), the corrective exercise (aka., wanna be PTs), the functional 3D training party, and so on.

Within these parties we have moderates and we also have the extremists, who’ve pledged their allegiance to their chosen style or system.

Now, we all know nothing ever gets agreed upon in politics. Although we all have the same goals, which is  to solve problems, the politics of fitness seem to prevent us from agreeing on the appropriate solutions.

Plus, it doesn’t help that the extremists continually cultivate a gang-like environment, and always seem ready to wage war to “prove” their way is “the right way”.


6. Conforming to the Norm




Studies shows that many of us will deny our own senses just to conform with others. (the below is taken directly from this post from PSYBlog)
“We all know that humans are natural born conformers – we copy each other’s dress sense, ways of talking and attitudes, often without a second thought. But exactly how far does this conformity go? Do you think it is possible you would deny unambiguous information from your own senses just to conform with other people?

Have a look at the figure below. Compare the line on the left with the three lines on the right: A, B & C. Which of these three lines is the same length as the lonesome line on the left?


It’s obviously C. And yet in a classic psychology experiment conducted in the 1950s, 76% of people denied their own senses at least once, choosing either A or B. (6)

The results were fascinating, and not at all what you’d expect:

  • 50% of people gave the same wrong answer as the others on more than half of the trials.
  • Only 25% of participants refused to be swayed by the majority’s blatantly false judgement on all of the 12 trials.
  • 5% always conformed with the majority incorrect opinion (we all know people like that, right?!)
  • Over all the trials the average conformity rate was 33%.
Intrigued as to why participants had gone along with the majority. They were interviewed after the experiment. Their answers are probably very familiar to all of us:

  • All felt anxious, feared disapproval from others and became self-conscious.
  • Most explained they saw the lines differently to the group but then felt the group was correct.
  • Some said they went along with the group to avoid standing out, although they knew the group was wrong.
  • A small number of people actually said they saw the lines in the same way as the group.
Fitness Industry Example of conformity: I’ve often heard trainers who challenge the group-think being called “contrarians.” (I’m one of them) Interestingly enough, that’s actually a compliment to a non-conformist type, as the alternative to an individual of that mind set is to be a spineless conformist who acts like a shadow and changes their position every time someone else does.


7. Confirmation Bias


“Confirmation bias refers to a type of selective thinking whereby one tends to notice and to look for what confirms one’s beliefs, and to ignore, not look for, or undervalue the relevance of what contradicts one’s beliefs. For example, if you believe that during a full moon there is an increase in admissions to the emergency room where you work, you will take notice of admissions during a full moon, but be inattentive to the moon when admissions occur during other nights of the month. A tendency to do this over time unjustifiably strengthens your belief in the relationship between the full moon and accidents and other lunar effects.” (taken directly from this post at Skepdic.com)

Another great explanation for Confirmation Bias comes from Paul Ingram, who’s website I really enjoy reading – “Confirmation bias explains a lot about human nature. Most people know it best as “selective hearing” or “selective memory” — hearing and remembering only what you want to hear. Confirmation bias is a whole lot more: a dazzling array of devious and largely unconscious mental tactics and thinking glitches that lead people to confirm their beliefs and pet theories. We not only tend to ignore, deny and overlook anything that contradicts our point of view, but we also invariably notice, inflate and or even fabricate anything that supports it. Confirmation bias is one of the main reasons that The Truth is so slippery, and both amateurs and experts alike are prone to significant thinking errors. There are people who strive to eliminate confirmation bias from their thinking — the best scientists and journalists, for instance — but it’s really difficult. Everyone has confirmation bias: it’s just how minds (don’t) work!”

Lessons & Take away for Fitness Pros


  •  The above Psychological factors make us ALL a little full of BS  Yes, even YOU, ME, and your favorite leaders, experts, gurus, teachers, etc.
  • When coming to judgements and conclusions, first look inward at yourself and ask yourself WHY you came to this conclusion. Ask yourself what are the counter arguments? And, ask yourself HOW you came to this conclusion? Is it based on emotion, science, following a leader…
  • We all have strong beliefs in our training philosophies, which is great because it shows we’re passionate. But, we can’t fool ourselves into believing that we’ve put more thought into what we do than anyone else has, whether they agree with us or disagree.
  • We must embrace our differences, have the discipline to accept our own weaknesses, and understand that we are only half as smart as we’ve tricked ourselves into believing we are.
  • Understand that when we feel someone needs to “learn more” or “use better logic/ common sense”, they’re most likely thinking the exact same thing about us!
  • Accept that we’re probably not as special as our moms told us we were.
  • Understand that arguing about fitness training and trying to prove why your way is best is probably not the best use of your time and mental energy, unless you like to be frustrated and/or hear yourself talk.
  • Rarely will training subjects reach a generally accepted expert consensus. So, waiting for one will keep you lost and confused. To get answers, we must take things into our own hands by searching for our own truth, which involves using our own better-judgement, common sense and scientific knowledge.

You’ll never be Right!


We all must choose whether we’d rather work to be “effective” or try to be “right.” I choose to be effective! And, understanding the 7 Psychological realities I’ve listed above have empowered me with knowledge to be a more effective learner and teacher. I hope you’re able to use this knowledge to do the same for you!

How does having weak muscles affect walking?

This study looks interesting.  We often tell people that strength will let them do al things better, being stronger makes everything easier (well I say that in Hillfit anyway)

This abstract is of a study that wanted to test the impact of weak muscles on gait.   They did it through various simulations, but it is still instructive.  Note that you can apparently get away with weak hip and knee extensors but when the plantar flexors (feet), hip abductors, and hip flexors get weak then your walking will be in trouble. 

Think about elderly people if we just got them doing some basic training for these muscles to strengthen them then we could really get their function up. 

How robust is human gait to muscle weakness?

Abstract
Humans have a remarkable capacity to perform complex movements requiring agility, timing, and strength. Disuse, aging, and disease can lead to a loss of muscle strength, which frequently limits the performance of motor tasks. It is unknown, however, how much weakness can be tolerated before normal daily activities become impaired. This study examines the extent to which lower limb muscles can be weakened before normal walking is affected. We developed muscle-driven simulations of normal walking and then progressively weakened all major muscle groups, one at the time and simultaneously, to evaluate how much weakness could be tolerated before execution of normal gait became impossible. We further examined the compensations that arose as a result of weakening muscles. Our simulations revealed that normal walking is remarkably robust to weakness of some muscles but sensitive to weakness of others. Gait appears most robust to weakness of hip and knee extensors, which can tolerate weakness well and without a substantial increase in muscle stress. In contrast, gait is most sensitive to weakness of plantarflexors, hip abductors, and hip flexors. Weakness of individual muscles results in increased activation of the weak muscle, and in compensatory activation of other muscles. These compensations are generally inefficient, and generate unbalanced joint moments that require compensatory activation in yet other muscles. As a result, total muscle activation increases with weakness as does the cost of walking. By clarifying which muscles are critical to maintaining normal gait, our results provide important insights for developing therapies to prevent or improve gait pathology.

Strength training for stroke survivors

When it comes to strength training I am an enthusiast.  More than that I aspire to be an evangelist.  I want people to understand and realise the benefits that come to everyone from basic strength training.  Yes, athletes benefit but so do non athletes, the office worker, the elderly and the sick.   Strength training can be simple but will benefit in so many ways - improved balance, fewer falls, better insulin sensitivity, better leptin sensitivity, better energy metabolism.  Yet all these benefits are a mystery to the average person.  Exercise is a brisk walk when some modified pushups and squats could do so much.

That was one of the ideas I am trying to get across in the Hillfit book - basic, simple strength training for hiking and backpacking.

This is another study that highlights the benefits of strength training for stroke survivors:

Maximal Strength Training Enhances Strength and Functional Performance in Chronic Stroke Survivors.

After training, leg press strength improved by 30.6 kg (75%) and 17.8 kg (86%); plantarflexion strength improved by 35.5 kg (89%) and 28.5 kg (223%) for the unaffected and affected limbs, respectively, significantly different from the control period (all P < 0.01). The 6-min walk test improved by 13.9 m (within training period; P = 0.01), and the Timed Up and Go test time improved by 0.6 secs (within training period; P < 0.05). There were no significant changes in walking economy, peak aerobic capacity, Four-Square Step Test, or health-related quality-of-life after training.

Maximal strength training improved muscle strength in the most affected as well as in the non affected leg and improved Timed-Up-And-Go time and 6-min walk distance but did not alter Four-Step Square Test time, aerobic status, or quality-of-life among chronic stroke survivors.
While this study did not look say quality of life improved, the Get up and Go test and the walk distance certainly indicate improvements in function. 

There is a similar study here (full pdf available)  High-Intensity Resistance Training Improves Muscle Strength, Self-Reported Function, and Disability in Long-Term Stroke Survivors

Walking, getting out of a chair, climbing stairs...these are skills for which we need strength as we get older and as we get injured.

D is for balance

An interesting review on the impact of Vitamin D supplementation on muscle strength, gait and balance in older adults

Effect of vitamin D supplementation on muscle strength, gait and balance in older adults: a systematic review and meta-analysis.

Supplemental vitamin D with daily doses of 800 to 1,000 IU consistently demonstrated beneficial effects on strength and balance. An effect on gait was not demonstrated, although further evaluation is recommended.

So one to give the old people....

You have a brain so you can move



This came via a very good post from Marc Keys. He talks about skill development.  As we have said before strength is one thing, skill development is another.  Get strong and then apply it to your chosen skill, something I talk about in Hillfit

Natural Messiah had a great discussion of this video a few months ago

Strength training increases efficiency

Just a  quick post just pointing out an abstract that I have noticed over the weekend.   Top of the list is this one:   Heavy Strength Training improved efficiency in cyclists.

Cyclists Improve Pedalling Efficacy and Performance After Heavy Strength Training.

It was tested whether heavy strength training, including hip flexion exercise, would reduce the extent of the phase in the crank revolution where negative or retarding crank torque occurs. Negative torque normally occurs in the upstroke phase where the leg is lifted by flexing the hip. Eighteen well-trained cyclists either performed twelve weeks of heavy strength training in addition to their usual endurance training (E+S; n = 10) or merely continued their usual endurance training during the intervention period (E; n = 8). The strength training consisted of four lower body exercises [3×4-10 repetition maximum (RM)], which were performed twice a week. E+S enhanced cycling performance by 7%, which was more than in E (P = 0.02). Performance was determined as average power output in a 5-min all-out trial performed subsequent to 185 min of submaximal cycling. The performance enhancement, which has been reported previously, was here shown to be accompanied by improved pedalling efficacy during the all-out cycling. Thus, E+S shortened the phase where negative crank torque occurs by ~16° corresponding to ~14%, which was more than in E (P = 0.002). In conclusion, adding heavy strength training to usual endurance training in well-trained cyclists improves pedalling efficacy during 5-min all-out cycling performed following 185 min of cycling.


Nice to have a bit more ammunition in my battle to get every athlete strength training.
