Fatigue can be defined as either emotional or physical tiredness. A primary goal of sports nutrition is to prevent fatigue during training or competition, in order to maximize fitness and athletic peformance. Fatigue can be produced by a variety of mechanisms and has the potential to hinder performance by many means. For example, in skill sports such as tennis, fatigue may reduce the athlete’s ability to accurately strike the ball.224 Another fatigue-induced hindrance to performance is a decrease in physical work capacity, which could affect performance in most sports.

Mental or physical tiredness, following prolonged or intense activity. Muscle fatigue may be due to the waste products of metabolism accumulating in the muscles faster than they can be removed by the venous blood. Incorrect or inadequate food intake or disease may predispose a person to fatigue.
A physiological state in which muscles become fatigued by the lactic acid accumulating in them as a result of their activity. Oxygen is required to remove lactic acid in the recovery phase of muscular contraction and, if the supply of oxygen is not plentiful enough, or cannot keep pace with the work the muscle is doing, then lactic acid accumulates and fatigue results. There is also a nervous element in muscular fatigue: it is diminished by stimulation of the sympathetic nervous system.
A n overwhelming sustained sense of exhaustion and decreased capacity for physical and mental work at the usual level.
