The purpose of this study was to evaluate maximal oxygen uptake during treadmill running and double-poling with a ski ergometer twice during the competitive season. A progressive double-poling power test was also performed to measure maximal power output. The athletes were five male and five female cross-country ski racers. Testing was done in December and April. Results showed that for both male and female skiers, no difference was observed during the competition season. Athletes were then divided into two subgroups according to whenever they had their peaking period early (December-January) or late (March-April) during the season. Skiers peaking early had significantly higher values for all measurements during the upper-body VO2peak test in December compared to April. Values for the upper-body VO2peak test of the skiers peaking late significantly increased from December to April, in accordance with their fitness state. Furthermore, results of the upper-body power test showed that there was no difference for the skiers peaking early for both testing periods, while power output increased significantly from December to April for the skiers peaking late. Thus specific upper-body tests appear to be more related to the fitness state of cross-country skiers than a running VO2max test.
本研究的目的是评估在比赛赛季期间，越野滑雪运动员在跑步机跑步和使用滑雪测力计进行两次双杖滑雪时的最大摄氧量。还进行了一次递增式双杖功率测试，以测量最大功率输出。运动员为五名男性和五名女性越野滑雪选手。测试在12月和4月进行。结果显示，对于男性和女性滑雪运动员来说，在比赛赛季期间未观察到差异。然后，根据运动员在赛季中达到峰值期的时间是早（12月至1月）还是晚（3月至4月），将他们分为两个亚组。与4月相比，在12月进行上身VO2峰值测试时，峰值期较早的滑雪运动员在所有测量指标上的值均显著更高。峰值期较晚的滑雪运动员上身VO2峰值测试的值从12月到4月显著增加，这与他们的体能状态相符。此外，上身功率测试结果表明，峰值期较早的滑雪运动员在两个测试期内没有差异，而峰值期较晚的滑雪运动员的功率输出从12月到4月显著增加。因此，特定的上身测试似乎比跑步VO2max测试更能反映越野滑雪运动员的体能状态。
