12名平均年龄为37．12岁的女教职工在进行一套历时20min的群众性健美操运动后，平均心率为156次／min，操前音乐前奏时的心率比相安静时的心率高出一倍。操后心输出量比静态下增加一倍左右，全操总摄氧量相当于800m和1500m跑，氧债比800m和1500m低，仅相当于10000m跑的氧债百分数。运动后血乳酸值在4毫克分子／以上，运动强度达“无氧阈”水平，属于有氧代谢运动。
Twelve female college staff, average age of 37.12 years old, had an average heart rate of 156 beats / min after performing a mass aerobics exercise lasting 20 minutes. The premorbid music heart rate was higher than that when they were quiet Double Cardiac output after exercise than doubled about static, total operating oxygen uptake equivalent to 800m and 1500m run, the oxygen debt is lower than 800m and 1500m, only equivalent to 10000m running oxygen debt percentage. After exercise, blood lactate value of 4 mg / or more, exercise intensity of “anaerobic threshold” level, belonging to aerobic metabolism exercise.
