Peak power output (PPO), also known as "peak work rate" is a common measure of exercise intensity.For example, researchers may ask subjects to complete an incremental exercise test where VO 2 max is measured while the person cycles at increasingly difficult power generation levels as measured by a cycle ergometer.
These findings suggest that warm-up is an unimportant factor in peak power levels, but if mean power is the variable of interest it is important to standardize the warm-up. Since the Wingate test stresses the anaerobic metabolic systems glucose consumption pre-testing can be another influential factor.
Exercise physiology is the physiology of physical exercise. It is one of the allied health professions , and involves the study of the acute responses and chronic adaptations to exercise. Exercise physiologists are the highest qualified exercise professionals and utilise education, lifestyle intervention and specific forms of exercise to ...
Scott Powers is an American physiologist, focusing on investigating the effects of muscular exercise and inactivity on both cardiac and skeletal muscle. He is currently the UAA Endowed Professor at University of Florida .
V̇O 2 max (also maximal oxygen consumption, maximal oxygen uptake or maximal aerobic capacity) is the maximum rate of oxygen consumption attainable during physical exertion. [1] [2] The name is derived from three abbreviations: "V̇" for volume (the dot over the V indicates "per unit of time" in Newton's notation), "O 2" for oxygen, and "max" for maximum and usually normalized per kilogram of ...
The Harvard Fatigue Laboratory is one of the many institutions responsible for the organisation of exercise physiology as a legitimate academic discipline. [5] 20% of the Academic material produced by the laboratory was specifically related to exercise physiology, and another 41% was associated with exercise in some way. [5]
Power training frequently specifically utilises two physiological processes which increase in conjunction with one another during exercise. These are deep breathing, which results in increased intra-abdominal pressure; and post-activation potentation, which is the enhanced activation of the nervous system and increased muscle fibre recruitment.
As the intensity level of the activity being performed increases, breathing becomes faster; more steadily first and then more rapid as the intensity increases. When breathing surpasses normal ventilation rate, one has reached ventilatory threshold. For most people this threshold lies at exercise intensities between 50% and 75% of VO 2 max. A ...
