Exercise physiology defines the nature of physiological processes underlying physical activities, comprehensive delivery of the treatment programs related to the analysis, improvement and the rehabilitation of heart disease and other diseases. The difference between exercise physiology and sports physiology is that sports physiology is a specific discipline which focusses on studying the impacts of training on the various athletes (Plowman and Denise 234) In contrast, exercise physiology is the general study of understanding the physiology of physical exercise. Unlike exercise physiology, sports physiology focusses on the physiology relating to the training of the specific sport.
Learning acute reactions to a single fit of exercise means the investigation of the human reactions to a specific exercise. For example, a resistance exercise uses an increase in the acute pressure of blood flow and increase secretion of hormones. The study will analyze the level of expanding hormone secretion relating to the resistance exercise. Thus, the assessment of the acute reactions of hormones relating to blood pressure about resistance exercises. It explains the nature of understanding the acute reactions to a single fit of exercise.
The three energy system includes the anaerobic A lactic (ALA) system, glycolysis, and aerobic system. Anaerobic a lactic (ALA) system provides a higher level of startup energy for events that can only last for few seconds (Shephard 198). The sprinters and weightlifters depend on ALA system as they require faster acceleration. The ALA energy system does not develop energy adequate for a long time. The Glycolytic energy systems produce energy ranging from medium to high level of activity which could last for more than ten seconds. Soccer players and middle distance runners rely on this system. They do not depend on oxygen for the production of fuel. Finally, the aerobic system is the highly used system of energy. The energy system produces the energy required for the low-intensity events which could last for few hours. They include continuous activities such as long distance running and swimming.
