An ecologically valid, reliable and sensitive method of quantifying punch force variables would be useful for coaches and practitioners monitoring combat-specific performance. The present study utilised a vertically mounted force plate to quantify the peak punch force and rate of force development (RFD) of amateur boxers. Ten male senior elite amateur boxers performed maximal jab, cross, and hook punches across two separate days. The force plate showed excellent within-day and good-to-excellent between-day reliability for peak punch impact force and RFD (ICC 0.89-0.99). The CV% for all punch force variables were similar on day 1 (3-9%) and day 2 (4-10%). Standard error of measurement (SEM) and smallest worthwhile changes (SWC) revealed the force plate can detect small-to-moderate changes in punch performance. The greatest impact forces and RFD were found in the rear hook (2624 ± 581 N, 296448 ± 101823 N.s-1), followed by the lead hook (2524 ± 532 N, 256813 ± 81735 N.s-1), cross 2425 ± 545 N, 193004 ± 62671 N.s-1) and jab (1645 ± 537 N, 116675 ± 41577 N.s-1). The vertically mounted force plate is a reliable and sensitive test of punch performance, thus may be useful in determining the efficacy of training interventions.
一种生态有效、可靠且敏感的定量击拳力变量的方法，对于监测特定战斗表现的教练和从业者将非常有用。本研究利用垂直安装的测力板来量化业余拳击手的最大刺拳、直拳和勾拳的最大击拳力和力发展速率（RFD）。10 名男性高级精英业余拳击手在两天内分别进行最大刺拳、直拳和勾拳的击打。测力板显示出出色的日内和良好至优秀的日间可靠性，用于峰值击拳力和 RFD（ICC 0.89-0.99）。所有击拳力变量的 CV%在第 1 天（3-9%）和第 2 天（4-10%）相似。测量误差（SEM）和最小有意义变化（SWC）表明测力板可以检测到击拳表现的小到中等变化。后勾拳的最大冲击力和 RFD 最大（2624 ± 581 N，296448 ± 101823 N.s-1），其次是前勾拳（2524 ± 532 N，256813 ± 81735 N.s-1）、直拳 2425 ± 545 N，193004 ± 62671 N.s-1）和刺拳（1645 ± 537 N，116675 ± 41577 N.s-1）。垂直安装的测力板是一种可靠且敏感的击拳性能测试方法，因此可能有助于确定训练干预措施的效果。
