When the load of fitness exercise exceeds the body's bearing capacity, it produces a temporary decline in physiological function, which is the change of body function caused by athletes' heavy exercise and high-intensity training in order to improve their sports performance. This is usually called exercise fatigue.
Fatigue is a normal reaction to training. Fatigue is generally divided into muscle fatigue, visceral fatigue and nerve fatigue. The degree of fatigue can generally be judged by athletes' self-feeling and some external manifestations.
