其他摘要：The training effect for aerobic work capacity was investigated in eight healthy women at ages of 34 to 50 years through ten weeks of training by 10 minutes bicyle pedaling every other day. The 80 percent of the pretraining maximal oxygen intake was loaded in dividually as training work intensity. As a result, the mean maximal bicycling time at a given constant load increased 234% at the end of training period. The mean maximal oxygen intake increased from 1.3 to 1.6 l/min (20%) or 25.4 to 30.1 ml/kg/min (19%) by training. The cardio-respiratory variables were shown by increased pulmonary ventilation from 50 to 61 l/min (22%) and oxygen pulse from 7.2 to 9.2 ml/beat (22%) while maximal heart rate did not change. The mechanical efficiency was improved. Therefore, the training work intensity corresponding to 80% of Vo_2max before training induced the improvement of aerobic work capacity on the middleaged women.
