The aim of this study was to investigate the effect of training intensity on maximal aerobic power on the basis of the subjects lean body mass. Seven sedentary adult females aged 23-40 years participated in a 44-week training experiment. They trained on a bicycle ergometer at progressive intensities of 60, 75, and 90% VO2 max for 13, 18, and 13 consecutive weeks, respectively. The total amount of work was between 9,000 and 12,000 kpm a day and frequency between 2 and 4 days a week, keeping both factors approximately constant for each subject throughout the 44-week training period. Mean VO2 max increased significantly during 60 and 90% VO2 max training. The increase during 75% VO2 max training was not significant. The final values during the three training periods were not necessarily the highest ones. Keeping the effect of age statistically constant, a significant partial correlation developed between the initial values and the total gains (%) of VO2 max, VE, and O2 pulse, expressed per lean body mass (LBM). The final attained values of VO2 max per LBM were significantly correlated with age. Therefore, if training intensity is sufficiently effective, it might be assumed that everyone has the same capacity for the improvement of cardiorespiratory function corresponding to their lean body mass, which is related to the magnitude of muscle mass. Furthermore, it might be said that the attainable level of aerobic power is greatly limited by the effects of age.
本研究的目的是基于受试者的瘦体重，探讨训练强度对最大有氧能力的影响。7名年龄在23 - 40岁之间久坐不动的成年女性参与了一项为期44周的训练实验。她们分别在自行车测力计上以60%、75%和90%最大摄氧量（VO2 max）的递增强度进行训练，持续时间分别为13周、18周和13周。每天的总运动量在9000至12000千帕米之间，每周训练频率为2至4天，在整个44周的训练期间，每个受试者的这两个因素大致保持不变。在60%和90%最大摄氧量训练期间，平均最大摄氧量显著增加。在75%最大摄氧量训练期间的增加不显著。三个训练阶段的最终值不一定是最高值。在年龄影响在统计学上保持不变的情况下，以每瘦体重（LBM）表示的最大摄氧量、每分钟通气量（VE）和氧脉搏的初始值与总增益（%）之间产生了显著的偏相关性。每瘦体重的最大摄氧量最终达到的值与年龄显著相关。因此，如果训练强度足够有效，可以假设每个人都有与其瘦体重相对应的改善心肺功能的相同能力，而瘦体重与肌肉量的大小有关。此外，可以说有氧能力的可达到水平受到年龄影响的极大限制。
