Ice sledge hockey is a popular paralympic team sport where players rely entirely on their upper body to propel themselves rapidly across the ice surface. The isolated and repetitive poling movements provide a good model for examining upper-body sprint ability and the related movement and strength characteristics. Therefore, the purpose of the present study was to investigate the relationship between upper-body maximal strength, power, and sprint performance in ice sledge hockey. Thirteen male ice sledge hockey players from the Norwegian national team performed three 30-m maximal sprint tests recorded by fixed light sensors. The best 30-m time for each subject was used for further analyses, and the sprint was analyzed more in detail for the first and last 10-m split times and kinematics (cycle length and rate) using photocells and 2-dimensional video analysis. One repetition maximum (1RM) strength and peak power were assessed in the bench press, bench pull, and pull-down exercises using a barbell and a linear encoder. Both 1RM strength and peak power for all the 3 strength exercises correlated significantly with the total sprint time (-0.75 < r < - 0.86, all p < 0.005), the first (0.60 < r < 0.72, all p < 0.05), and the last (0.74 < r < 0.83, all p < 0.05) 10-m split times in the 30-m sprint test. There were no significant relationships between sprint kinematics and 1RM strength and peak power. Overall, these results demonstrate that there are close relationships between upper-body strength, power, and sprint performance in highly trained athletes and that the ability to produce propulsion and high frequency in combination is important for the sprint abilities in ice sledge hockey.
冰橇曲棍球是一项流行的残奥会团队运动，运动员完全依靠上半身在冰面上快速推进。孤立的、重复的撑杆动作提供了一个很好的模型，可以用来检查上半身的短跑能力以及相关的运动和力量特征。因此，本研究的目的是探讨冰橇曲棍球运动员上半身最大力量、功率和短跑性能之间的关系。13 名来自挪威国家队的男性冰橇曲棍球运动员进行了三次 30 米最大冲刺测试，由固定光传感器记录。每位受试者的最佳 30 米时间用于进一步分析，并且对第一次和最后一次 10 米分段时间和运动学（周期长度和速度）进行了更详细的分析，使用光电管和二维视频分析。使用杠铃和线性编码器评估了卧推、卧拉和下拉练习中的 1 次重复最大力量（1RM）和峰值功率。所有 3 项力量练习的 1RM 力量和峰值功率与总冲刺时间（-0.75<r< -0.86，均 p<0.005）、第一次（0.60<r<0.72，均 p<0.05）和最后一次（0.74<r<0.83，均 p<0.05）10 米分段时间呈显著相关。冲刺运动学与 1RM 力量和峰值功率之间没有显著关系。总的来说，这些结果表明，在高度训练的运动员中，上半身力量、功率和短跑性能之间存在密切关系，并且产生推进力和高频的能力对于冰橇曲棍球的短跑能力很重要。
