A laboratory test was developed to study the metabolic and gas exchange effects of arm, leg and combined arm and leg work. The test incorporated movement patterns similar to those used in cross-country skiing. The work rate for the arm test at maximal effort was 33% (125 watts) and the leg test was 81% (302 watts) of that for the combined test (375 watts). The maximum oxygen uptake (VO2 max) was not significantly different when comparing the leg test to the combined test, but VO2 at submaximal work levels was significantly less during the combined test. The anaerobic threshold (AT) occurred at 68, 73 and 76% of VO2 max for the arm, leg, and combined test, respectively. Although there were no significant differences in VO2 and percent of VO2 max, at the AT between the leg test and the combined test, AT was significantly delayed with respect to time and work rate in the latter condition. Application of these results to cross-country skiing supports the proposal for greater upper body involvement in skiing.
开发了一项实验室测试，以研究手臂、腿部以及手臂和腿部联合运动对代谢和气体交换的影响。该测试采用了与越野滑雪中使用的类似运动模式。手臂测试在最大努力时的工作强度为联合测试（375瓦）的33%（125瓦），腿部测试为81%（302瓦）。将腿部测试与联合测试相比较时，最大摄氧量（VO2 max）无显著差异，但在次最大工作强度水平下，联合测试期间的VO2显著更低。手臂、腿部和联合测试的无氧阈（AT）分别出现在VO2 max的68%、73%和76%时。尽管腿部测试和联合测试之间在VO2及VO2 max百分比方面，在无氧阈时无显著差异，但在联合测试中，无氧阈在时间和工作强度方面显著延迟。将这些结果应用于越野滑雪，支持了在滑雪中增加上半身参与度的提议。
