Measuring parameters vs embodied exercise

Sports are dominated by all kinds of machinery that measure body parameters to improve and control performance. More and more devices are construed to give more and more detailed information about our body’s condition. Nevertheless body sense is a term that in the end always comes into the game if parameters are not conclusive, and in many ways they are not.
I found an article in the Psychology Today Blog that underlines the importance of the body sense and the ability to assess the condition of well-being. It goes very much along with an article I myself wrote about this topic, and may encourage you to a less structured training program that takes the body sense more into consideration.

One of the sentences that athletes and coaches love to say is: “The most important thing you can do to recover quickly is to listen to your body. If you are feeling tired, sore or notice decreased performance you may need more recovery time or a break from training altogether. If you are feeling strong the day after a hard workout, you don’t have to force yourself to go slow. If you pay attention, in most cases, your body will let you know what it needs, when it needs it.”

The problem for many of us is that we don’t listen to the warnings of overreaching or over-training as there are general malaise, fatigue, mood instability, lack of motivation, loss of appetite, fragmented sleep, delayed muscle soreness, disturbed body temperature regulation etc… or that we are misinterpreting body signs.

The good thing about this post is that it brings body sense into the loop of understanding exercise physiology. Body sense herewith is accepted as a biological and not only psychological phenomenon. We know a lot about metabolism and muscle during and after exercise but less focus is placed on how exercise feels in our bodies. Learning to feel the body during any type of activity enhances the body’s ability to most effectively marshal its resources to enhance health and well being.

More muscles help to burn more fat …

Currently Ross Tucker is writing about this topic on the Science of Sport blog. I want to pick up this topic very briefly, because as we know even among lean athletes weight is a crucial issue of discussion all the year through. The gossip around training your metabolism to burn more fat is fairly noisy, controversial and not very profoundly based on evidence. This has got to do with the fact that reliably measuring parameters of energy consumption and moreover to measure the kind of energy used is not trivial. While the procedures are very time-consuming and possibly invasive (e.g. muscle biopsies), the results for the individual are volatile, and contribute more to statistics than giving you advise on a very personal level. The data you get on an individual basis depend so much on your training, your diet regimen, the actual time of measuring that results can only give a rough guideline and may vary from individual to individual and intra-individually as well.

Energy use and loss follow the rules of macro-physics, at least we don’t know any better until now. The thought concept behind still seems to be applicable: you only lose weight, if your energy balance is negative regardless of the energy source your body uses. Of course, this does not indicate that you cannot train and optimize your metabolism. It only may say that low-intensity workouts don’t make you lose more weight than high-intensity ones. If you burn fewer calories than your intake may be then weight loss remains a dream, and weighing a shear frustration.

It is known that athletes have more effective fat burning capacities compared to sedentary individuals. This I think is easy to explain. Sedentary people are reaching the point, at which the energy contribution from carbs becomes greater than that from fat a lot earlier than well-trained athletes. This cross-over point (named by George Brooks, a very famous exercise physiologist) is relative to a person’s training condition. The conclusion is straight forward: If your body is well trained, you enter the zone in which mainly carbs are burned later than an untrained person.

Therefore workout and increasing your muscle instead of your adipose tissue brings about burning more calories and more fat. Obese persons are often disappointed, that they don’t lose weight despite reducing the calorie intake. Maybe they don’t have the muscles that help them burn more fat? Therefore one advise among thousand others may be to work more on an intensity program than remaining in the cardio or fat burning zone as many coaches and machines ;-) in gyms recommend.

Beneficial effects of exercise other than weight loss

Currently biestmilch is supporting a weight loss program of two of its friends. My view on this topic was from the beginning that the guys should not focus on weight loss only, should not put the scale into the center of concern as other health aspects may be even more important and significant, as there are blood pressure, aerobic capacity and resting heart rate.

Today I found confirmation in the current issue of the British Journal of Medicine. Dr. N. King and his co-workers from the Institute of Health and Biomedical Innovation, School of Human Movement Studies, Queensland University of Technology in Brisbane, Australia published a study that underlines the approach that weight loss is not the one and only health benefit of exercise. Their study group of 58 overweight sedentary individuals undertook the effort of physical workouts 5 times a week for 12 weeks. Energy expenditure was 500 kcal per session. It is interesting and important to know that weight loss was less than expected for the majority of the participants. But they showed other positive changes which are of great significance for the health condition of an individual. (more…)

Symmetry: a principle of perfection and surrogate parameter to adjust exercise and training?

Recently, I have been training with my personal coach as I do twice every week, and it came that we were discussing the topic of symmetry. I enjoy this luxury of having a coach since I am suffering from pains in my foot that I cannot not control anymore. The pain keeps me away from running which really influences my mood negatively ;-) … sorry, I am zoning out!

Analyzing my body we found out that over decades I have developed a kind of a patchwork of asymmetry that disturbs economic and efficient movements. Compensatory actions and postures added up. The result is a mess that is extremely difficult to tackle.  Symmetry, so my hypothesis, is an ideal state of a biological organism that facilitates optimal functionality, and is rarely achieved or never, as it would mean complete perfection.

Today I found a talk by Marcus du Sautoy about symmetry that just fits into my current deliberations.

Marcus Peter Francis du Sautoy (born in London, 26 August 1965) is a Professor of Mathematics at the University of Oxford. His academic work concerns mainly group theory and number theory. (more…)

Heat stroke: A problem of physiology, not fluid or environment

This post refers back to the one from yesterday that outlines the scientific approach to proove a cause by a »post-hoc assumption of a cause-effect relation«. Conclusions drawn like this are fairly arbitrary and result in data that drift and seem incorrect as soon as the standpoint of observation changes.
Under whatsoever extreme environmental conditions heat stroke is a rare event that funnily enough occurs under conditions that would never let us assume it to happen. The proof of concept is easily performed by a mathematical equation that should not be applied to real life, to real persons, because of its over-simplification.
But mathematics clearly shows that heat loss even in extreme situations like hot temperature over 35°C, no wind, high humidity, bright sunshine and low running efficiency exceeds heat storage.

The example:

Theoretically this runner cannot experience a heat stroke, no, he is even able to evaporate more heat. To keep his body temperature exactly the same, he would have to evaporate 1.5 L of sweat per hour. The calculation also reveals that it would be possible for him to evaporate 1.6 L of sweat per hour. This means that he has no problem loosing the heat he produces, and should not develop heatstroke

But the story of real life turns out to be completely different:
This runner, running in these conditions, was pulled out of the race after only 16 minutes, with a rectal temperature of 40.8°C!
Therefore, despite the fact that there were no limitations in the environment, and the fact that he COULD have lost all the heat he produced, he failed. And the result was that he developed heat stroke after less than 4km of running!

At first sight it looks funny, but it is serious!

These days the discussion about exercise in hot and humid conditions is prevailing. This video shows how hard it can be to coordinate the movements of your body once your brain doesn´t work adequate any more.
