Aerobic endurance, also called aerobic capacity. Refers to the ability to work with long-term aerobic energy supply. The load intensity is 75%-85% of the maximum load intensity of human body, and the heart rate is generally 1 10- 150 beats/min. The time is at least 5 minutes, generally more than 15 minutes. The physiological factors that determine the aerobic endurance of the body are mainly the supply of oxygen during exercise and the content of glycogen as an energy substance.
Extended data:
Maximum oxygen uptake of aerobic endurance and its physical exercise. Maximum oxygen uptake refers to the amount of oxygen consumed by tissues and cells per minute when the body exerts its maximum functional level. Maximum oxygen uptake is the basis of aerobic metabolism. The average person's maximum oxygen intake is 2-3 liters/minute, and people who often participate in physical exercise can reach 4-5 liters/minute.
In aerobic endurance exercise, the maximum oxygen uptake can be used as a reference index to determine the exercise intensity. For young adults with good physical function, the exercise intensity can be equivalent to 80% of the maximum oxygen uptake; For the elderly, it is more appropriate to use 40-60% of the maximum oxygen intake intensity to develop aerobic endurance.
