Abstract：
Ice hockey requires two levels of specific agility, involving different abilities, where the level of agility and their constraints might vary by the performance level. Therefore, this study aimed to compare the relationship level between on-ice and off-ice change of directional speed (COD) of youth hockey players at two performance levels. The study was conducted during the hockey season, including U16 elite players (n = 40) and U16 sub-elite players (n = 23). Both groups performed specific on-ice fitness tests (4-m acceleration, 30-m sprint, and 6 x 54-m tests, an on-ice Illinois agility test with and without a puck) and off-ice tests consisting of non-arm swing countermovement jumps (CMJs), broad jumps, and pull-ups. Pearson correlation showed that the acceleration performance of elite players was related to the CMJ (r = -0.46) and the broad jump (r = -0.31). Sub-elite players showed stronger dependence of the 30-m sprint on the CMJ (r = -0.77) and the broad jump (r = -0.43), the relation of pulls ups (r = -0.62) and the CMJ (r = -0.50) to the 6 x 54-m test, yet no association to acceleration. Elite players differ between off-ice and on-ice performance constraints, where their skating sprint is less related to their vertical and horizontal take-off abilities than in sub-elite players. Sub-elite players\' off-ice power determines their sprint and repeated sprint performance. COD performance of elite and sub-elite players is based on different conditioning constraints.
摘要：
冰球需要两个级别的特定敏捷性，涉及不同的能力，其中敏捷性水平及其约束可能因性能水平而异。因此,本研究旨在比较青年曲棍球运动员在两个成绩水平上的冰上和非冰上方向速度（COD）变化之间的关系水平。这项研究是在曲棍球赛季进行的，包括U16精英玩家（n=40）和U16次精英玩家（n=23）。两组都进行了特定的冰上适应性测试（4-m加速度，30米冲刺,和6x54-m测试，有和没有冰球的伊利诺伊州冰上敏捷性测试）和非冰上测试，包括非臂摆动反向跳跃（CMJ），广泛的跳跃，和引体向上。皮尔逊相关性显示，精英球员的加速表现与CMJ（r=-0.46）和跳远（r=-0.31）有关。次精英球员表现出对CMJ（r=-0.77）和跳远（r=-0.43）的30米冲刺的更强依赖性，拉升(r=-0.62)和CMJ(r=-0.50)与6x54-m试验的关系，但与加速度无关。精英玩家在非冰上和冰上性能限制之间存在差异，与次精英选手相比，他们的滑冰冲刺与垂直和水平起飞能力的关系较小。亚精英玩家\'冰外力量决定了他们的冲刺和重复冲刺表现。精英和次精英玩家的COD表现基于不同的条件约束。
