This study compared the metabolic cost of ice skating and in-line skating in Division I collegiate hockey players. Heart rate and oxygen uptake were compared between the two conditions at three skating velocities: 12.5 km.h-1, 16.5 km.h-1, and 20 km.h-1. Twelve subjects were tested on two occasions: on ice (ice skating) and off ice (in-line skating). They skated for 3 min at each velocity, with heart rate recording and gas collection taking place during the final 30 s of each stage. A two-factor repeated measures ANOVA revealed that the chosen velocities affected the two conditions differently for heart rate (p < .01). No interaction between condition and velocity was found for absolute (p < .43) and relative (p < .15) oxygen uptake. In-line skating produced significantly greater heart rate values and absolute oxygen uptake values than ice skating at all three velocities (p < .05). In-line skating also generated significantly greater relative oxygen uptake values at 16.5 km.h-1 and 20 km.h-1. Results suggest that the metabolic cost of in-line skating is greater than that of ice skating for collegiate ice hockey players when skating at three velocities similar to those skated during game conditions.
本研究比较了一级大学冰球运动员滑冰和轮滑的代谢成本。在三种滑冰速度下（12.5公里/小时、16.5公里/小时和20公里/小时），比较了两种情况下的心率和摄氧量。12名受试者在两种情况下接受测试：在冰上（滑冰）和不在冰上（轮滑）。他们在每种速度下滑冰3分钟，在每个阶段的最后30秒记录心率并收集气体。双因素重复测量方差分析显示，所选速度对两种情况下的心率影响不同（p < 0.01）。在绝对摄氧量（p < 0.43）和相对摄氧量（p < 0.15）方面，未发现情况与速度之间存在交互作用。在所有三种速度下，轮滑产生的心率值和绝对摄氧量值均显著高于滑冰（p < 0.05）。在16.5公里/小时和20公里/小时时，轮滑产生的相对摄氧量值也显著更高。结果表明，对于大学冰球运动员来说，在与比赛条件下相似的三种速度滑冰时，轮滑的代谢成本高于滑冰。
