What is exercise physiology? It is the intricate study of how the human body responds to different levels of physical activity. This study closely monitors the body’s metabolic rate, the stability of fluid, circulation of oxygen as well as the muscle endurance. It is a very complex area of study, but it helps us gain better understanding of the inner athlete and its complexities.
Physiology is said to be a sub-divisional study of kinesiology. But unlike kinesiology, the study of exercising physiology is more focused on what happens inside the human body while it is under a constant regime of physical activity. While the body is in the state of cardiac activity (sprinting, intense cardio etc.), blood flow to the muscle will become essential as well as cause an increase in oxygen supplied from the heart. According to the British Journal of Anesthesia, the heart rate increases to approximately 90% of its ultimate strength when someone is performing in physically (Burton and Stokes, 185-188).
The most common chemicals present during this period, are Adenosine Triphosphate (ATP), Phosphocreatine (PCr) and Glycolysis. The role of ATP serves as a provider of energy and stores energy in complex chemical bonds, during muscle contractions. PCr works in a similar way to ATP, but the only difference is, PCr works to resynthesize ATP in order to provide additional energy to the body’s muscle. Glycolysis, on the other hand, stimulates the pathway for two sugar molecules, glycogen and glucose, which diffuse into two pyruvate molecules. This diffusion is essential for the body’s oxygen supply to the muscles. The acid from the pyruvate molecules called Pyruvate Acid becomes subsidized into a Lactic Acid molecule; which is commonly known to cause post-exercise stiffness. In order for the body to alleviate build up of Lactic Acid, the individual should withdraw from any physical activity for a couple days, until the build-up subsides. Another solution for lactic acid to be avoided, is by loading up on nutrients such as, electrolytes, Vitamins, etc.
Exercise physiology is one of the most interesting but yet difficult subject matter to comprehend. Once researchers have developed research about exercising physiology, they’ll be able to support moderately to severely injured patients and may even prevent muscle injuries for prospering athletes.
