Dos'Santos, T, Thomas, C, Comfort, P, McMahon, JJ, Jones, PA, Oakley, NP, and Young, AL. Between-session reliability of isometric midthigh pull kinetics and maximal power clean performance in male youth soccer players. J Strength Cond Res 32(12): 3373-3381, 2018-The aim of the study was to determine the between-session reliability of isometric midthigh pull (IMTP) kinetics and maximal weight lifted during the power clean (PC) in male youth soccer players, and to identify the smallest detectable differences between sessions. Thirteen male youth soccer players (age: 16.7 ± 0.5 years, height: 1.80 ± 0.08 m, and mass: 70.5 ± 9.4 kg) performed 3 IMTP trials, whereas only 10 soccer players performed maximal PCs. These were performed twice, separated by 48 hours to examine the between-session reliability. Intraclass correlation coefficients (ICCs) and coefficient of variation (CV) demonstrated high levels of within-session (ICC = 0.84-0.98, CV = 4.05-10.00%) and between-session reliability (ICC = 0.86-0.96, CV = 3.76-7.87%) for IMTP kinetics (peak force [PF] and time-specific force values 30-250 ms) and maximal PC (ICC = 0.96, CV = 3.23%), all meeting minimum acceptable reliability criteria. No significant differences (p > 0.05, effect size ≤0.22) were revealed between sessions for IMTP kinetics and maximal PC performance. Strength and conditioning coaches and practitioners should consider changes of >6.04% in maximal PC and changes in IMTP kinetics of >14.31% in force at 30 ms, >14.73% in force at 50 ms, >12.36% in force at 90 ms, >12.37% in force at 100 ms, >14.51% in force at 150 ms, >11.71% in force at 200 ms, >7.23% in force at 250 ms, and >8.50% in absolute PF as meaningful improvements in male youth soccer players. Decrements in the IMTP kinetics greater than the aforementioned values could possibly be used as an indicator of neuromuscular fatigue and preparedness for training or competition.
多斯桑托斯、T、托马斯、C、舒适、P、麦克马洪、JJ、琼斯、PA、奥克利、NP 和杨、AL. 男性青年足球运动员等速大腿中部拉力动力学和最大力量清洁性能的组间可靠性。J 力量与条件研究 32(12)：3373-3381，2018 年-本研究的目的是确定男性青年足球运动员等速大腿中部拉力（IMTP）动力学和最大力量清洁（PC）期间最大举起重量的组间可靠性，并确定组间的最小可检测差异。13 名男性青年足球运动员（年龄：16.7±0.5 岁，身高：1.80±0.08m，体重：70.5±9.4kg）进行了 3 次 IMTP 试验，而只有 10 名足球运动员进行了最大 PC。这些在 48 小时内进行了两次，以检查组间的可靠性。组内相关系数（ICC）和变异系数（CV）显示了较高的组内（ICC=0.84-0.98，CV=4.05-10.00%）和组间可靠性（ICC=0.86-0.96，CV=3.76-7.87%）的 IMTP 动力学（峰值力[PF]和 30-250ms 时的特定时间力值）和最大 PC（ICC=0.96，CV=3.23%），均符合最小可接受的可靠性标准。IMTP 动力学和最大 PC 性能在两次测试之间没有显示出显著差异（p>0.05，效应量≤0.22）。力量和调节教练和从业者应考虑最大 PC 变化>6.04%和 IMTP 动力学力的变化>14.31%在 30ms 时，>14.73%在 50ms 时，>12.36%在 90ms 时，>12.37%在 100ms 时，>14.51%在 150ms 时，>11.71%在 200ms 时，>7.23%在 250ms 时，>8.50%在绝对 PF 中，这是男性青年足球运动员的有意义的提高。大于上述值的 IMTP 动力学衰减可能被用作神经肌肉疲劳和训练或比赛准备的指标。
