exercise fatigue
Introduction
Introduction At the 5th International Conference on Sports Biochemistry in 1982, exercise fatigue was defined as: "The physiological process of the body cannot sustain its function at a certain level or maintain its predetermined exercise intensity." Exhaustion is a special form of fatigue. Form, it is to continue to exercise when fatigue, until the muscles or organs can not maintain exercise, that is exhausted.
Cause
Cause
Decreased muscle exercise capacity is the basic sign and essential characteristic of exercise fatigue. Since the beginning of this century, researchers have done a lot of research on sports fatigue from different angles. It is suggested that the negative effect of exercise stress metabolism may be the root cause of exercise fatigue, such as the depletion of metabolic matrix and metabolites. Accumulation, acidification of the metabolic environment. They may cause changes in muscle fiber structural integrity, energy supply, neurohumoral regulation, etc. through various channels, leading to motor muscle contraction and diastolic dysfunction. Therefore, the decline in exercise capacity, that is, fatigue, is the inevitable result.

The location and changes of exercise fatigue:
Exercise fatigue can be divided into physical fatigue and psychological fatigue in the human body. These two different types of fatigue have different manifestations. Physical fatigue is mainly manifested in decreased exercise capacity; psychological fatigue is mainly manifested in behavioral changes. Fatigue can occur in all parts of the body, from central cerebral cortical cells to basic contractile units of skeletal muscle. According to the research results, physical fatigue is divided into central fatigue and peripheral fatigue. Central fatigue refers to a lack of motivation, changes in the transmission or recruitment of the central nervous system. Peripheral fatigue includes a decrease in the ability of joint transfer, muscle point activity, and muscle contraction activity. Only physical fatigue is described here.
Diagnosis
Differential diagnosis
Differential diagnosis of exercise fatigue:
1. Emotional fatigue: It refers to people who have been engaged in some monotonous and mechanical work activities for a long time. With the changes in the body's biochemistry, the central nervous cells in the central region are inhibited due to continuous tension, resulting in a significant decrease in people's enthusiasm and interest in life. Until you get bored. The main manifestation of emotional fatigue is behavioral change. Fatigue can occur in all parts of the body, from central cerebral cortical cells to basic contractile units of skeletal muscle.
2, tension fatigue: long-term stress, resulting in a sub-health state of fatigue, severe formation of tension sleep disorders.
