Describe The Causes Of Fatigue During Exercise

Question

Describe The Possible Causes Of Fatigue During Exercise Bouts Of Ex Fatigue during exercise is a common phenomenon influenced by multiple physiological and psychological factors. One primary cause is energy depletion, where glycogen stores within muscles are exhausted, leading to decreased ATP production necessary for muscle contraction (Bishop et al., 2002). Additionally, the accumulation of metabolic byproducts, such as lactic acid, contributes to muscle fatigue by disrupting the normal function of muscle fibers and causing discomfort (Allen et al., 2008). Neurophysiological factors also play a role; central nervous system fatigue occurs when perceived exertion increases, reducing motor drive from the brain to muscles, which limits performance (Meeusen & De Meirleir, 1995). Furthermore, dehydration and electrolyte imbalances impair muscle function and thermoregulation, increasing exhaustion risk during prolonged physical activity (Sawka et al., 2007). Psychological factors like motivation and mental fatigue influence perceived effort, potentially causing premature fatigue even when physiological reserves are sufficient (Di domizio et al., 2018). Overall, fatigue results from a complex interaction of muscular, metabolic, neural, and psychological components that disrupt efficient physical performance during exercise bouts. My personal experience with fatigue during physical activity has involved feeling drained and experiencing muscle soreness after intense workouts, especially if I did not adequately hydrate, fuel, or warm-up. These sensations signal that my body is working beyond its current capacity, often due to accumulated metabolic byproducts and energy depletion. I have noticed that increasing rest periods and ensuring proper nutrition helps delay fatigue, allowing me to sustain activity longer. Additionally, listening to my body's signals and adjusting the intensity or duration of exercise can prevent excessive fatigue, thereby reducing the risk of burn
