摘要
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。
12 women with the average age of 37.12 were examined in this test. After performing a set of popular aerobic exercises for 20 minutes their average heart rate (HR) was 156. During the prelude it was twice as many as at rest, and after exercise their cardiac output was doubled. The total oxygen uptake was qual to that of 800m. race or 1500m. race, but the percentage of oxygen debt was lower, just as many as that in 10,000 m. race. After exercise the blood lactate level was above 4mmol/l, which showed that the imtensity was at the anaerobic threshold (At) level. It belongs to aerobic metabolic movements.
