The purpose of this study was to compare skating economy and oxygen uptake (VO2) on-ice and on the skating treadmill (TM). Male varsity hockey players (n = 15, age = 21.0 yr) performed skating tests on a TM and on-ice. The subjects skated for 4 min at each of 3 submaximal velocities (18, 20, and 22 km . h(-1)), separated by 5 min of passive recovery. A VO2max test followed the submaximal tests and commenced at 24 km . h(-1) with the velocity increasing by 1 km . h(-1) every minute until volitional fatigue. VO2 was 39.7, 42.9, 46.0, and 53.4 ml . kg(-1) . min(-1) at 18, 20, 22, and maximum speed (km . h(-1)) on the TM. VO2 was significantly lower (p < .05) 31.5, 36.9, and 42.7 ml . kg(-1) . min(-1) at 18, 20, and 22 km . h(-1) on-ice. The on-ice VO2max (54.7 ml . kg(-1) . min(-1)) was similar to TM. Stride rate, stride length and heart rate (HR) were significantly different on-ice compared to TM. These results show that at submaximal velocities, VO2, HR, and stride rate are higher on TM compared to on-ice. VO2max was similar while HRmax was higher on the skating treadmill compared to on-ice
本研究的目的是比较冰上和在滑冰跑步机（TM）上的滑行经济性和摄氧量（VO₂）。男子大学曲棍球队员（n = 15，年龄 = 21.0岁）在TM上和冰上进行了滑行测试。受试者在3个次最大速度（18、20和22 km·h⁻¹）下各滑行4分钟，中间间隔5分钟的被动恢复。次最大测试后进行VO₂max测试，从24 km·h⁻¹开始，速度每分钟增加1 km·h⁻¹，直至自愿疲劳。在TM上，速度为18、20、22和最大速度（km·h⁻¹）时，VO₂分别为39.7、42.9、46.0和53.4 ml·kg⁻¹·min⁻¹。在冰上，速度为18、20和22 km·h⁻¹时，VO₂显著更低（p < 0.05），分别为31.5、36.9和42.7 ml·kg⁻¹·min⁻¹。冰上的VO₂max（54.7 ml·kg⁻¹·min⁻¹）与TM上相似。与TM相比，冰上的步频、步长和心率（HR）有显著差异。这些结果表明，在次最大速度下，与冰上相比，TM上的VO₂、HR和步频更高。VO₂max相似，而与冰上相比，滑冰跑步机上的HRmax更高。
