Unformatted text preview: 6/11/11 1 Exercise, Training and Racing 34 The goal of these lectures is to discuss basic physiology associated with the control of exercise, training and racing. The sections for this lecture are: Life is a series of chemical reactions occurring in compartmentalized environments. The main purpose of life is to keep itself alive Physiology, the study of how life works, is based on the simultaneous occurrence of the following three concepts: levels of organization structure / function homeostatic regulation Basic physiological responses to exercise in the human athlete How great running athletes are horses Training horses for running events Stress and the horse and human athletes Exercise, Training & Racing Basic physiological responses to exercise in the human athlete How great running athletes are horses Training horses for running events Stress and the horse and human athletes Exercise and training are good models to review basic physiological responses 6/11/11 2 The Human Athlete Basic physiological responses to exercise in the human athlete How great running athletes are horses Training horses for running events Stress and the horse and human athletes Exercise and training are good models to review basic physiological responses The Human Athlete Basic physiological responses to exercise in the human athlete How great running athletes are horses Training horses for running events Stress and the horse and human athletes ATP for muscle contraction is continuously produced by aerobic metabolism of glucose and fatty acids. During short bursts of activity, when ATP demands exceeds the rate of aerobic ATP production, anaerobic glycolysis produces ATP, lactate and H ions. 6/11/11 3 ATP for muscle contraction is continuously produced by aerobic metabolism of glucose and fatty acids. During short bursts of activity, when ATP demands exceeds the rate of aerobic ATP production, anaerobic glycolysis produces ATP, lactate and H ions. The Human Athlete Basic physiological responses to exercise in the human athlete How great running athletes are horses Training horses for running events Stress and the horse and human athletes The Human Athlete Basic physiological responses to exercise in the human athlete How great running athletes are horses Training horses for running events Stress and the horse and human athletes At low-intensity exercise, muscles get more energy from fats than from glucose. During high-intensity exercise (levels greater than 70% of maximum), glucose becomes the main energy source. 6/11/11 4 The Human Athlete Basic physiological responses to exercise in the human athlete How great running athletes are horses Training horses for running events Stress and the horse and human athletes Oxygen supply to exercising cells lags behind energy uses, creating an energy de f cit....
