The purpose of this study was to develop and assess the reliability of a repeated anaerobic power cycling test designed to mimic the repeated sprinting nature of the sport of ice hockey. Nineteen female varsity ice hockey players (mean X +/- SD age, height and body mass = 21 +/- 2 yr, 166.6 +/- 6.3 cm and 62.3 +/- 7.3) completed 3 trials of a repeated anaerobic power test on a Monark cycle ergometer on different days. The test consisted of "all-out" cycling for 5 seconds separated by 10 seconds of low-intensity cycling, repeated 4 times. The relative load factor used for the resistance setting was equal to 0.095 kg per kilogram body mass. There was no significant difference between the peak 5-second power output (PO), mean PO, or the fatigue index (%) among the 3 different trials. The peak 5-second PO was 702.6 +/- 114.8 w and 11.3 +/- 1.1 w x kg, whereas the mean PO across the 4 repeats was 647.1 +/- 96.3 w and 10.4 +/- 1.0 w x kg averaged for the 3 different tests. The fatigue index averaged 17.8 +/- 6.5%. The intraclass correlation coefficient for peak 5-second, mean PO, and fatigue index was 0.82, 0.86, and 0.82, respectively. This study reports the methodology of a repeated anaerobic power cycling test that was reliable for the measurement of PO and calculated fatigue index in varsity women ice hockey players and can be used as a laboratory-based assessment of repeated anaerobic fitness.
本研究旨在开发和评估一种重复的无氧功率循环测试，该测试旨在模拟冰球运动的重复冲刺性质。19 名女子大学冰球运动员（平均 X +/- SD 年龄、身高和体重=21 +/- 2 岁、166.6 +/- 6.3 厘米和 62.3 +/- 7.3）在不同的日子里在 Monark 功率自行车上完成了 3 次重复无氧功率测试。该测试由 5 秒的“全力”骑行和 10 秒的低强度骑行组成，重复 4 次。用于阻力设置的相对负荷系数等于每公斤体重 0.095 公斤。在 3 次不同的试验中，峰值 5 秒功率输出（PO）、平均 PO 或疲劳指数（%）之间没有显著差异。峰值 5 秒 PO 为 702.6 +/- 114.8 w 和 11.3 +/- 1.1 w x kg，而 4 次重复的平均 PO 为 647.1 +/- 96.3 w 和 10.4 +/- 1.0 w x kg，这是 3 次不同测试的平均值。疲劳指数平均为 17.8 +/- 6.5%。峰值 5 秒、平均 PO 和疲劳指数的组内相关系数分别为 0.82、0.86 和 0.82。本研究报告了一种重复的无氧功率循环测试的方法，该方法在大学女子冰球运动员中测量 PO 和计算疲劳指数是可靠的，可以作为重复无氧适应性的实验室评估。
