VO2 Max Formula 130818

By Danny M. O’Dell, M.A. CSCS*D

Interested in what your VO2 Max may be?

Here is a quick method to find out without using high priced equipment. It is equated to how far you are able to run in 12 minutes. K. H. Cooper, of the famed Cooper Institute came up with this equation for aerobic fitness.

The protocol is to warm up efficiently as it will be a maximum effort. Warm up and run on a level course. The course selected should have markings in meters so you know how far you have gone at the conclusion.

The equation:
VO2 max= 33 + 0.17 (x-133)
X is the distance (in meters) covered in one minute

060818 Building Athletic Movement

Physical athleticism requires precise mastery and powerful execution of specific sport movement/motor system patterns. In order to accomplish these multifaceted demands on the body each of the interacting sequential muscle groups within the kinematic chain and kinematic system have to be functioning and producing their peak tension at the exact right time.

In the beginning stages of learning a new skill or exercise the dynamic elements are weak, which makes the law of facilitation immediately relevant. This law states that each time a movement is performed wrong it becomes easier to repeat and harder to execute the right pattern in the future. With each repetition the movement becomes more difficult to correct. Fortunately these early mistakes don’t have long lasting effects on the system-if they are continually modified in closer approximations of the exact movement.

As the pattern becomes closer to perfect the body automatically finds more effective ways to reconcile the discrepancies of the motor unit’s interrelationships. These changes are the result of differentiations in, and increases within the emphasis of neuromuscular output at the varying times necessary to produce maximum power when needed in the chain of events.

It is at this time in the training sequence that performance of correct repetitions begins to take hold. The relationship between the movement strength amplitude curve and the execution time decreases indicating approaching movement perfection.

Once this takes place the process is complete and the movement is performed technically correct with little to no wasted energy.

Summary:

Continual training in the techniques of your sport at the closest equivalent to perfection requires constant attention to the detailed execution of each movement pattern.

Physical athleticism requires precise mastery and powerful execution of specific sport movement/motor system patterns. In order to accomplish these multifaceted demands on the body each of the interacting sequential muscle groups within the kinematic chain and kinematic system have to be functioning and producing their peak tension at the exact right time.

Each exercise or sport movement is formed by and evolves from a cause and effect relationship with the individual elements making up the pattern. The line of force which is developed to successfully complete these movements depends on the efficiency of the neuromuscular system. The relationship between these mechanisms is constantly changing in an effort to find the most balanced response to the required movement pattern. Meanwhile additions to the dynamic element are being added to the equation.

This latter represents the ‘rigid framework’ i.e. the determination of the spatial time parameters and the working effect of the movement. It is this dynamic concept that is vitally important to the athlete and their coach.

The dynamics of the patterns depend on the interaction with the sport implement; in the case of the lifter, the loaded barbell of dumbbell. This interaction is further divided into concentration and the dynamic reaction to the load.

Expanding on this interactive process leads one to the conclusion that we are not just discussing the physical expressions of the movement but also the process that evolves during the active accentuation of the motor unit’s responses to the external stimuli, i.e. the load.

In order to accomplish these multifaceted demands on the body each of the interacting sequential muscle groups within the kinematic chain and kinematic system have to be functioning and producing their peak tension at the exact right time.

Acknowledgment of the forgoing leads to these observations:

  • The body determines the most rational activation of the individual kinematic chains.
  • The individual parts that make up the chain will be integrated into this arrangement in a high powered flowing state of continuity.
  • Perfection in training continuously alters the organism’s responses.

While the successful intelligent athlete trains and continues to develop more highly defined skills the body is adapting by forming complex engrams within the neuromuscular system. These neural changes make major contributions to the rapid and fluid movements that are a necessary part of all sports.

It comes as no surprise that if you are addicted to something there are going to be changes in brain activity that clearly shows up on brain scans. Nora D. Volkow, M.D. the director of the national Institute on Drug Abuse analyzed dopamine levels in obese adults. The results of these scans advanced the theory of potential addiction to food.

Even though investigation into the theory of food addiction is continuing, there have been only a few studies on its prevalence. Recently investigators at Yale University developed a questionnaire that helps identify people showing signs of addiction to high fat and sugar foods.

Their research is leaning towards a comparatively small percentage of individuals within a wide range of weight categories that may actually be addicted to food. This 2011 study found that just about 11% of college students in the normal weight ranges may be considered addicted to food. Contrast this study with one recently conducted in Germany that found of the 750 people studied using the Yale University questionnaire nearly 38% of the obese participants and 14% of those overweight were addicted to food. They went so far as to say that 10% of the underweight participants and 6% in the normal weight categories in the study were also addicted to food.

As far as Kelly Brownell, PhD., Director of the Yale Rudd Center for Food Policy and Obesity is concerned ” there’s no longer any question about that in my mind” when asked about the concept of food and addiction being a viable source contributing to the obesity situation currently exploding in our nation.

If you feel that you may be addicted to food or any other substance, take time to set up an appointment with your healthcare provider and get help.

Volkow, M.D. the director of the national Institute on Drug Abuse analyzed dopamine levels in obese adults. The results of these scans advanced the theory of potential addiction to food.

In October of 2011, researchers at the Oregon Research Institute in Eugene, Oregon updated the original 2001 research. They noticed during MRIs, that regions of the brain directly related to reward and the senses were brighter in obese who anticipated a chocolate milkshake more so than when they were actually drinking the milkshake. This was not the case with the MRIs of those leaner girls participating in the study.

This would indicate that people who find food to be exciting are more likely to eat more, which results in weight gain. Going back to the original research findings in October 2011, the results of the MRIs clearly show that the more you eat high-fat and high sugar foods the less your brain responds to these foods. The outcome of such a situation is a greater internal demand for these types of foods, which ultimately results in eating more to achieve the same feeling of pleasure.

At this point is important to note that not all members of the American Psychiatric Association subscribe to the food addiction theory and it has not been formally recognized as such by this association. The objective evidence that food addiction exists is presently lacking, which leads us down the road to a question of whether not the possibility of food addiction contributes greatly to the epidemic of obesity in our nation or not.

020718 Avoiding Exercise Rhabdomyolysis

Avoiding Exercise Rhabdomyolysis

A classic case of too much, too often, and too soon is seen in those who suffer the ill and sometimes fatal after effects of working out far beyond their physical capacity.

Rhabdomyolysis in much simpler terms means that the exercise has been so extensive and strenuous that the muscle fibers themselves have not only broken down but have separated from the main fiber itself. This leads to these wayward fibers entering the circulatory system.

Some of these bits of tissue are toxic to the body and can result in kidney damage.

The person most at risk for this condition is inexperienced in exercise and is pushed either by themselves or an incompetent coach far beyond their limits. Others who may be put in the danger zone are military recruits in basic training, those who are dehydrated or suffering from heat related issues, and the circuit trainee under the supposed guidance of a personal trainer and of course the ultra marathon and triathlon athletes.

The clues of this dangerous condition are found in the abnormal and dark colored urine of the individual. This urine will have a dark, red or cola color to it.

This is a danger sign that should not be dismissed. If rhabdomyolysis is suspected, take immediate steps to have the symptoms and potential life threatening condition expertly evaluated by a physician.

Saving the life of another may be at stake here.
