Six male and six female elite speed skaters were tested during two bicycle ergometer tests: a 30 s sprint test and a 2.5 min supra maximal test. During the 2.5 min test oxygen consumption was measured every 30 s. The males showed 30-31% higher mean power output values both during the sprint test (1103 versus 769 Watt) and during the 2.5 min test (570 versus 390 Watt). Maximal oxygen consumption was 31% higher for the males than for the females (5.10 versus 3.50 1.min-1). However, when expressed per kilogram lean body weight (LBM), power output and oxygen consumption was equal for both sexes. Differences between present and previous results are most likely due to methodological problems with the estimation of load during the supra maximal test. Subjects appear to experience difficulties in distributing their power output over the 2.5 min if they are tested for the first time. For experienced skaters and cyclists, fixed levels of 19 W.kgLBM-1 as initial load setting for the sprint test and 8 W.kg LBM-1 for the 2.5 min test are recommended.
一次30秒的冲刺测试和一次2.5分钟的超最大测试。在2.5分钟的测试中,每隔30秒测量一次耗氧量。男性在冲刺测试(1103瓦对769瓦)和2.5分钟测试(570瓦对390瓦)中的平均功率输出值均高出30 - 31%。男性的最大耗氧量比女性高31%(5.10对3.50升·分钟⁻¹)。然而,按每千克瘦体重(LBM)计算时,两性的功率输出和耗氧量是相等的。当前结果与先前结果之间的差异很可能是由于超最大测试中负荷估计的方法学问题。如果受试者是首次接受测试,他们似乎在2.5分钟内分配功率输出方面存在困难。对于有经验的速滑运动员和自行车运动员,建议将冲刺测试的初始负荷设定为19瓦·千克LBM⁻¹,2.5分钟测试的初始负荷设定为8瓦·千克LBM⁻¹。
