The purposes of this study were (a) to determine the measurement device and jumping protocol most appropriate for testing the leg power of elite hockey players and (b) to assess the relationship of leg power measurements to hockey playing ability as indicated by draft selection order. Comparisons were made of leg power measurements from the top 95 players entering the National Hockey League Entry Draft using 2 devices (Vertec and Just Jump) and 2 jump protocols (countermovement and squat). Players' leg powers were ranked from highest to lowest power using each device and protocol and were correlated with draft selection order. Vertec leg power measurements were highest (5,511-5,631 W), but there were no significant differences in power between the 2 jumping protocols on either device. Vertec squat jump provided the highest correlation (0.47) between leg power ranking and selection order and was judged to most closely approximate the full-body coordinated movements involved in hockey. The Vertec device using a squat jump protocol is most appropriate for coaches and fitness specialists to use when evaluating hockey potential based on the off-ice leg power measurements of elite hockey players.
(a)确定最适合测试精英曲棍球运动员腿部力量的测量设备和跳跃方案;(b)根据选秀顺序评估腿部力量测量值与曲棍球比赛能力之间的关系。使用两种设备(Vertec和Just Jump)和两种跳跃方案(反向移动和深蹲),对进入国家曲棍球联盟选秀大会的前95名球员的腿部力量测量值进行了比较。使用每种设备和方案,将球员的腿部力量从最高到最低进行排名,并与选秀顺序进行关联。Vertec测量的腿部力量最高(5511 - 5631瓦),但两种设备上的两种跳跃方案之间的力量没有显著差异。Vertec深蹲跳在腿部力量排名和选秀顺序之间提供了最高的相关性(0.47),并且被认为最接近曲棍球中涉及的全身协调运动。当根据精英曲棍球运动员的冰上腿部力量测量值评估曲棍球潜力时,使用深蹲跳方案的Vertec设备最适合教练和体能专家使用。
