Six Danish male cross-country skiers were studied during the end-of-summer and winter seasons. Their maximal oxygen uptake was measured while running on a treadmill and using a ski ergometer incorporating the double-poling technique. Maximal oxygen uptake during treadmill running and double-poling was correlated with performance, expressed as a ranking score during 10 ski races. The tests were undertaken in September, December and April. Upper body maximal oxygen uptake increased 5.8% from September to December, decreasing to 2.3% above the September level in April. Upper body work output (2 min at maximal intensity) increased 11.8% from September to December (P less than 0.05). The relationship between upper body and leg maximal oxygen uptake--the upper body/leg ratio--was 89.4% in September. In four skiers, both treadmill and upper body tests were undertaken on each test occasion. The upper body/leg ratio changed from 87.7% in September to 95.7% in December. In April, the ratio was 91.0%. The maximal oxygen uptake measured using the ski ergometer during double-poling was significantly correlated with performance (P less than 0.05). It is concluded that the upper body ski ergometer can be used in the evaluation of elite cross-country skiers.
对六名丹麦男子越野滑雪运动员在夏末和冬季进行了研究。在跑步机上跑步以及使用采用双杖技术的滑雪测力计期间，测量了他们的最大摄氧量。跑步机跑步和双杖运动期间的最大摄氧量与表现相关，表现以十场滑雪比赛中的排名分数表示。测试在九月、十二月和四月进行。上身最大摄氧量从九月到十二月增加了5.8%，到四月降至比九月水平高2.3%。上身工作输出（最大强度下两分钟）从九月到十二月增加了11.8%（P小于0.05）。上身与腿部最大摄氧量的关系——上身/腿部比率——在九月为89.4%。在四名滑雪运动员中，每次测试时都进行了跑步机和上身测试。上身/腿部比率从九月的87.7%变为十二月的95.7%。在四月，该比率为91.0%。双杖运动期间使用滑雪测力计测量的最大摄氧量与表现显著相关（P小于0.05）。得出的结论是，上身滑雪测力计可用于评估优秀越野滑雪运动员。
