Participation in physical activity, exercise, or sports causes physiological changes to an individual’s body. In particular, physiological changes entail the alteration of normal body functioning.
First, participation in physical activity increases the heartbeats, which means that more blood is pumped to different body organs. Specifically, while at rest, the skeletal and skin muscles get approximately 20% of oxygen. During exercise, these muscles receive around 80% of the oxygen (CDC, n.d.). In other words, the increase of blood flow in the body contributes to the supply of oxygen in various parts to foster endurance to physical activity.
Second, the rate of metabolism increases when one is performing physical exercises. Notably, the metabolic rate involves the use of energy by the body. Participation in sports increases metabolism, which means that a person must consume more food than when he or she is resting. That is the reason why an individual is advised to take food rich in carbohydrates before exercising and vitamins afterward.
Third, the endocrine system, su...
