Gillen, ZM, Miramonti, AA, McKay, BD, Jenkins, NDM, Leutzinger, TJ, and Cramer, JT. Reliability and sensitivity of the power push-up test for upper-body strength and power in 6-15-year-old male athletes. J Strength Cond Res 32(1): 83-96, 2018-The power push-up (PPU) test is an explosive upper-body test performed on a force plate and is currently being used in high school football combines throughout the United States. The purpose of this study was to quantify the reliability of the PPU test based on age and starting position (knees vs. toes) in young athletes. Sixty-eight boys (mean ± SD; age = 10.8 ± 2.0 years) were tested twice over 5 days. Boys were separated by age as 6-9 years (n = 16), 10-11 years (n = 26), and 12-15 years (n = 26). The PPU test was performed on a force plate while rotating from the knees vs. the toes. Measurements were peak force (PF, N), peak rate of force development (pRFD, N·s), average power (AP, W), and peak power (PP, W). Intraclass correlation coefficients (ICC2,1), SEMs, coefficients of variation (CVs), and minimum detectable changes (MDCs) were calculated to quantify reliability and sensitivity. Peak force from the knees in 10-15-year-olds, PF from the toes in 12-15-year-olds, and pRFD from the knees and toes in 12-15-year-olds were comparably reliable (ICC ≥ 0.84). Neither power measurements (AP or PP) for any age group, nor any measurements (PF, pRFD, AP, or PP) for the 6-9-year-olds were comparably reliable (ICC ≤ 0.74). When considering the reliable variables, PF was greater in the 12-15-year-olds than in 10-11-year-olds (p ≤ 0.05). In addition, in 12-15-year-olds, PF and pRFD were greater from the knees than from the toes (p ≤ 0.05). For reasons largely attributable to growth and development, the PPU test may be a reliable (ICC ≥ 0.80) and sensitive (CV ≤ 19%) measure of upper-body strength (PF), whereas pRFD was also reliable (ICC ≥ 0.80), but less sensitive (CV = 30-38%) in 10-15-year-old male athletes.
吉尔伦,ZM,米拉蒙蒂,AA,麦凯,BD,詹金斯,NDM,勒图森,TJ,克拉默,JT。6-15 岁男性运动员上肢力量和功率的功率俯卧撑测试的可靠性和敏感性。J 力量与调节研究 32(1):83-96,2018-功率俯卧撑(PPU)测试是一种在力量板上进行的爆发力上肢测试,目前正在美国各地的高中足球综合测试中使用。本研究的目的是根据年龄和起始位置(膝盖与脚趾)量化年轻运动员中 PPU 测试的可靠性。68 名男孩(均值±标准差;年龄=10.8±2.0 岁)在 5 天内进行了两次测试。男孩按年龄分为 6-9 岁(16 名)、10-11 岁(26 名)和 12-15 岁(26 名)。PPU 测试在力量板上进行,同时从膝盖到脚趾旋转。测量指标为峰值力(PF,N)、峰值力量发展率(pRFD,N·s)、平均功率(AP,W)和峰值功率(PP,W)。计算了组内相关系数(ICC2,1)、SEM、变异系数(CV)和最小可检测变化量(MDC),以量化可靠性和敏感性。10-15 岁儿童从膝盖处的 PF、12-15 岁儿童从脚趾处的 PF 和 12-15 岁儿童从膝盖和脚趾处的 pRFD 具有可比性(ICC≥0.84)。没有任何年龄组的功率测量值(AP 或 PP),也没有任何测量值(PF、pRFD、AP 或 PP)在 6-9 岁儿童中具有可比性(ICC≤0.74)。考虑到可靠的变量,12-15 岁儿童的 PF 大于 10-11 岁儿童(p≤0.05)。此外,在 12-15 岁儿童中,从膝盖处的 PF 和 pRFD 大于从脚趾处的 PF 和 pRFD(p≤0.05)。由于主要归因于生长和发育,PPU 测试可能是一种可靠的(ICC≥0.80)和敏感的(CV≤19%)上半身力量(PF)测量方法,而 pRFD 也是可靠的(ICC≥0.80),但在 10-15 岁男性运动员中,敏感性较低(CV=30-38%)。
