Neurophysiology plays an important role in terms of physical strength and sporting performance. Fatigue among sportspersons is a major limiter of performance. Therefore, the mechanism and the nature of the exercise associated fatigue should be well understood. The paper will touch on the some theories that attempt to explain the nature of fatigue.
Brief Background and Findings of Previous Literature
Several physiologists have attempted to explain the complex associations between fatigue and dynamic sports performance (Hargreaves, 2008). Several models in effect have been developed such as the peripheral fatigue model, the central governor model and lately being the task dependency model (Weir, et al., 2006; Swart, et al., 2009).

According to Weir and colleagues (2006), the lactic acid model had been a widely accepted model, which explained the nature of fatigue during an exercise. Lactic acid phenomena were a major descriptor of the principles of governing the peripheral fatigue model. Peripheral fatigue model was also termed as the limitation, the cardiovascular, the anaerobic, or the catastrophic model of fatigue justification (Weir, et al., 2006). However, Weir, et al. (2006) points out that the peripheral fatigue model does not explain the nature of fatigue in a complete manner. Noakes and colleagues (2005) argued that peripheral fatigue or the catastrophe fatigue does not explain the nature of exercise associated …show more content…
(2006), the subconscious mind seems to regulate the manner in which the body utilizes available energy during strenuous sport with respect to maintenance of normal body homeostasis. Comparatively, Swart and colleagues (2009) admitted that the central nervous system (CNS) is involved in power regulation during prolonged exercises. Similarly, Noakes and colleagues (2005) wrote in support of the central governor model. The brain and the body works as a complex integrated system during an exercise. The degree of skeletal muscle recruitment during an exercise is controlled by the central nervous system as a component of a continuously changing pacing strategy (Noakes, et al.,
