The aim of this study was to examine biomechanical variables relating to the force production of men's Lightweight (LW) and Heavyweight (HW) rowing pairs. Seven HW and seven LW coxless pairs were studied under a range of stroke rates, from 20 spm to race rating (average of 33.7 spm for the HWs and 33.9 spm for the LWs). Each crew was equipped with biomechanical apparatus allowing the measurement of gate force, horizontal oar angle, and boat velocity. The HW crews exhibited significantly higher (p < 0.05) values for all variables examined, at all rates. Peak handle force was 26.2% to 30.2% higher in the HW group. Average handle force ranged from 18.7% to 22.1% higher than the LW group. Work per stroke was found to be 26% to 28% higher for the HW crews, and Power Per Kilogram was also greater for the HW crews, from 24.0% to 29.2%. The LWs were observed to be consistently, but not significantly, slower than the HWs (from 96.9% at the race situation, to 98.7% at 28 spm). These observations are important when considering biomechanical performance indicators in rowing, as significant changes in performance indicators may lead to only minimal alteration in boat velocity.
本研究旨在探讨与男子轻量级（LW）和重量级（HW）赛艇双人艇划桨力量产生相关的生物力学变量。在 20 个划桨频率至比赛评级（HW 的平均频率为 33.7 个，LW 的平均频率为 33.9 个）的范围内，对七对 HW 和七对 LW 无舵双人艇进行了研究。每支队伍都配备了生物力学仪器，可测量桨架力、水平桨角和船速。HW 艇手在所有测试速度下的所有变量都表现出显著更高的（p < 0.05）值。HW 组的桨手峰值手柄力高出 26.2%至 30.2%。平均手柄力比 LW 组高出 18.7%至 22.1%。HW 组的每次划桨做功量比 LW 组高 26%至 28%，而每公斤功率也比 LW 组高，从 24.0%到 29.2%。LW 组的船速始终比 HW 组慢，但没有显著差异（从比赛情况下的 96.9%到 28 个划桨频率时的 98.7%）。这些观察结果在考虑划船的生物力学表现指标时很重要，因为表现指标的显著变化可能只会导致船速的微小改变。
