Using an air-braked cycle ergometer, we sought to determine the relative contributions of the arms and legs in eliciting the maximal O2 uptake (VO2max). Ten healthy, non-arm-trained males did progressive exercise to exhaustion on the ergometer instrumented to partition the push-pull arm exercise from the cycling leg exercise. Exercise was done with arms only (100% arms), legs only (100% legs, with arms at sides), and in combinations of 10% arms/90% legs, 20% arms/80% legs, and 30% arms/70% legs. To approximate conventional bicycling, four subjects exercised to exhaustion doing leg cycling on the air-braked ergometer with the hands fixed to stationary bars. The maximal power output and VO2max were not significantly different (P greater than 0.05) for the 10% arms/90% legs and the 20% arms/80% legs combinations. Maximal power output and VO2max for 10% arms/90% legs was significantly greater than that for the 100% arms, 100% legs, and 30% arms/70% legs regimens (P less than 0.05). The highest VO2max measured in combined arm/leg exercise for four subjects using 10% arms/90% legs (N = 3) or 20% arms/80% legs (N = 1) was not significantly different from that measured in air-braked ergometer leg cycling with hands fixed to stationary bars (P greater than 0.05). We conclude that push-pull arm exercise of 10 or 20%, combined with leg cycling of 90 or 80%, respectively, or leg cycling with hands fixed to bars optimize the arm/leg contributions in eliciting VO2max. These findings suggest that the upper-body stabilizing effort in conventional cycling (legs cycling, hands fixed) contributes approximately 10-20% to inducing VO2max.(ABSTRACT TRUNCATED AT 250 WORDS)
我们使用一台配备空气制动的自行车测力计，试图确定手臂和腿部在引发最大摄氧量（VO₂max）方面的相对贡献。十名健康的、未经过手臂训练的男性在该测力计上进行渐进性运动直至 exhaustion，该测力计被设计用于区分手臂的推拉运动和腿部的骑行运动。运动分别仅使用手臂（100% 手臂）、仅使用腿部（100% 腿部，手臂放在身体两侧），以及 10% 手臂/90% 腿部、20% 手臂/80% 腿部和 30% 手臂/70% 腿部的组合方式进行。为了近似传统骑自行车的情况，四名受试者将手固定在固定杆上，在空气制动测力计上进行腿部骑行直至 exhaustion。10% 手臂/90% 腿部和 20% 手臂/80% 腿部组合的最大功率输出和 VO₂max 没有显著差异（P 大于 0.05）。10% 手臂/90% 腿部的最大功率输出和 VO₂max 显著大于 100% 手臂、100% 腿部和 30% 手臂/70% 腿部方案的相应值（P 小于 0.05）。四名受试者在使用 10% 手臂/90% 腿部（N = 3）或 20% 手臂/80% 腿部（N = 1）的手臂/腿部联合运动中测得的最高 VO₂max 与手固定在固定杆上进行空气制动测力计腿部骑行时测得的 VO₂max 没有显著差异（P 大于 0.05）。我们得出结论，分别为 10% 或 20% 的手臂推拉运动与 90% 或 80% 的腿部骑行相结合，或者手固定在杆上进行腿部骑行，可优化手臂/腿部在引发 VO₂max 方面的贡献。这些发现表明，传统骑行（腿部骑行，手固定）中上身的稳定作用对诱导 VO₂max 的贡献约为 10 - 20%。（摘要截短至 250 字）
