Arm and leg work was performed on bicycle ergometers in sitting position by fourteen women and sixteen men. Heart rate, minute volume of ventilation (VE), and oxygen consumption (VO2) were measured. Arm exercise was performed until (muscular) exhaustion, leg exercise up to a heart rate of circa 170 beats/min. At comparable work loads arm exercise evoked higher VO2, VE, and heart rate than leg exercise irrespective of sex. At comparable VO2, the heart rate and VE were higher during arm work in both sexes, VE more so among the men. With the same limbs working, the mechanical efficiency was equal in both sexes. The regression coefficients of heart rate on load or VO2 was higher for the women irrespective of work type. A close correlation was obtained between working capacity at a heart rate of 170 beats/min (W170) during leg and arm exercise and between W170 of leg exercise and W150, similarly calculated during arm work. Thus W170 of leg exercise could be calculated from either a maximal or submaximal arm work.
14名女性和16名男性坐在自行车测力计上进行手臂和腿部运动。测量了心率、每分通气量（VE）和耗氧量（VO2）。手臂运动持续到（肌肉）力竭，腿部运动则持续到心率约为170次/分钟。在相当的工作负荷下，无论性别，手臂运动引起的VO2、VE和心率均高于腿部运动。在相当的VO2水平下，男女在手臂运动时的心率和VE均较高，男性的VE更高。在相同肢体运动时，男女的机械效率相同。无论工作类型如何，女性心率对负荷或VO2的回归系数更高。在腿部和手臂运动时心率为170次/分钟时的工作能力（W170）之间，以及腿部运动的W170与手臂运动时类似计算的W150之间，均获得了密切的相关性。因此，腿部运动的W170可以通过最大或次最大手臂运动来计算。
