This study was undertaken to determine whether levels of conditioning associated with conventional leg work are comparable to those associated with both arm and leg work. Six healthy men conditioned for 6 weeks using both arms and legs while a similar group of 5 men conditioned using legs alone. The subjects trained 3 times per week on a bicycle ergometer, and covered a distance of 3 miles (4.83 km) per session using interval training techniques. Oxygen consumption (VO2) and heart rate (HR) were the primary comparative measures. There were no differences in improvement of maximal aerobic power between the 2 groups. However, the arm and leg subjects were able to do more work at a lower HR during the conditioning program. This implies considerably less physical stress on the heart and skeletal muscle, and indicates that the feeling of stress is related to metabolic rate per square area of working muscle rather than to total metabolism. Since this type of conditioning provides high levels of improvement in aerobic power wit less demands on the myocardium, it is suggested that arm and leg exercise be incorporated in the rehabilitation of cardiac patients.
本研究旨在确定与传统腿部训练相关的体能训练水平是否与手臂和腿部联合训练的水平相当。六名健康男性使用手臂和腿部进行了6周的体能训练，而另一组由五名男性组成的相似群体仅使用腿部进行训练。受试者每周在自行车测力计上训练3次，每次训练采用间歇训练技术骑行3英里（4.83公里）。耗氧量（VO2）和心率（HR）是主要的比较指标。两组之间最大有氧能力的改善没有差异。然而，在体能训练计划中，手臂和腿部联合训练的受试者能够在较低的心率下完成更多的工作量。这意味着心脏和骨骼肌承受的身体压力要小得多，并且表明压力感与工作肌肉每单位面积的代谢率有关，而不是与总代谢有关。由于这种类型的体能训练在对心肌需求较少的情况下能显著提高有氧能力，因此建议将手臂和腿部运动纳入心脏病患者的康复训练中。
