To compare a novel sprint test on a cycle ergometer with a countermovement-jump (CMJ) test for monitoring neuromuscular fatigue after Australian rules football match play.
Twelve elite under-18 Australian rules football players (mean ± SD age 17.5 ± 0.6 y, stature 184.7 ± 8.8 cm, body mass 75.3 ± 7.8 kg) from an Australian Football League club's Academy program performed a short sprint test on a cycle ergometer along with a single CMJ test 1 h prematch and 1, 24, and 48 h postmatch. The cycle-ergometer sprint test involved a standardized warm-up, a maximal 6-s sprint, a 1-min active recovery, and a 2nd maximal 6-s sprint, with the highest power output of the 2 sprints recorded as peak power (PP).
There were small to moderate differences between postmatch changes in cycle-ergometer PP and CMJ PP at 1 (ES = 0.49), 24 (ES = -0.85), and 48 h postmatch (ES = 0.44). There was a substantial reduction in cycle-ergometer PP at 24 h postmatch (ES = -0.40) compared with 1 h prematch.
The cycle-ergometer sprint test described in this study offers a novel method of neuromuscular-fatigue monitoring in team-sport athletes and specifically quantifies the concentric component of the fatigue-induced decrement of force production in muscle, which may be overlooked by a CMJ test.
比较在自行车功率计上进行的新型冲刺测试与反向纵跳（CMJ）测试，以监测澳大利亚式足球比赛后的神经肌肉疲劳。
来自澳大利亚足球联赛俱乐部青训项目的12名18岁以下精英澳大利亚式足球运动员（平均年龄±标准差17.5±0.6岁，身高184.7±8.8厘米，体重75.3±7.8千克）在比赛前1小时以及比赛后1、24和48小时，在自行车功率计上进行了一次短距离冲刺测试，并进行了一次CMJ测试。自行车功率计冲刺测试包括标准化热身、6秒全力冲刺、1分钟主动恢复以及第二次6秒全力冲刺，记录两次冲刺中最高的功率输出作为峰值功率（PP）。
比赛后1小时（效应量=0.49）、24小时（效应量=-0.85）和48小时（效应量=0.44），自行车功率计PP和CMJ PP的赛后变化存在小到中等程度的差异。与比赛前1小时相比，比赛后24小时自行车功率计PP大幅下降（效应量=-0.40）。
本研究中描述的自行车功率计冲刺测试为团队运动运动员提供了一种监测神经肌肉疲劳的新方法，并且具体量化了疲劳引起的肌肉力量产生下降的向心成分，而这可能被CMJ测试忽略。
