The ability of muscle tissue to abs

The ability of muscle tissue to absorb and utilize oxygen in the blood is closely related to aerobic endurance. The quality of aerobic endurance is not only related to cardiovascular function or oxygen transport system, but also closely related to the utilization capacity of oxygen, namely the composition of muscle fibers and their aerobic metabolism ability Neuroregulatory ability. The stability of neural processes in the cerebral cortex and the coordination between different centers directly affect the development of endurance quality. Improving neural regulation ability can improve the mechanical efficiency of muscle activity, save energy consumption, and maintain long-term muscle activity Energy supply characteristics. The aerobic metabolic capacity of the body is closely related to the quality of aerobic endurance. Endurance exercise has a long duration and low intensity, with the vast majority of energy provided by aerobic metabolism. (2) The factors that affect the development of anaerobic endurance depend on the ability of muscle glycolysis to provide energy, the tolerance of brain cells to changes in blood pH, and the ability to buffer lactate The ability of muscle anaerobic glycolysis to provide energy. The ability of muscle anaerobic glycolysis mainly depends on the content of muscle glycogen and the activity of anaerobic enzymes. Therefore, the anaerobic glycolytic ability of muscles is closely related to the quality of anaerobic endurance The tolerance of brain cells to changes in blood pH values. Although the buffering substances in the human body can neutralize some of the lactic acid entering the blood, due to the large amount of lactic acid entering the blood, the pH value of the blood will also develop towards acidity. In addition, the accumulation of metabolic products due to insufficient oxygen supplyFatigue can affect the working ability of brain cells and promote the occurrence of fatigue. Therefore, the tolerance of brain cells to these negative factors is also an important factor affecting anaerobic endurance The ability to buffer lactic acid. When lactic acid produced during anaerobic muscle fermentation enters the blood, it can have an impact on the pH value of the blood. However, due to the buffering effect of the buffering system, the pH value of the blood does not undergo significant changes, which is beneficial for the development of training and anaerobic endurance. （2） The foundation of endurance training mainly refers to the biological factors that affect the development of endurance. The development of endurance quality is mainly influenced by the stability of neural processes, reserve of energy substances, maximum oxygen uptake level, proportion of red muscle fibers, and the ability of the human body to withstand oxygen debt
