The objective of this investigation was to compare isokinetic strength, countermovement jump and drop jump variables between high-contributors and low-contributors within NCAA Division I Men's and Women's lacrosse athletes. Men's (N=36) and Women's (N=30) NCAA Division I lacrosse athletes completed strength testing of the quadriceps and hamstring across three speeds (60°·s, 180°·s, 300°·s), countermovement and drop jumps. To determine the discriminative ability of select lower-limb strength and power characteristics participants were categorized as high-contributors (Males N=18, age=20.3±0.4 yrs, height=183.9±5.5 cm, mass=90.8±5.8 kg; Females N=15, age=20.8±0.8 yrs, height=169.3±6.7 cm, mass=64.1±7.2 kg) or low-contributors (Males N=18, age=19.5±0.2 yrs, height=184.1±5.6 cm; mass=87.9±8.1 kg; Females N=15, age=19.7±0.2 yrs, height=169.8±7.0 cm, mass=62.9±7.7 kg ) based upon the number of games the participants competed in during the regular season. Within the male cohort, moderate significant (p<0.05) differences were observed between high-contributors and low-contributors in isokinetic hamstring strength of the left leg at 300°·s (d=0.69) and peak power in countermovement jump (0.68). Within the women's cohort a large (0.87) significant difference (p<0.05) in isokinetic strength of the left hamstring was observed between high-contributors and low-contributors at 60°·s. Hamstring strength and lower-limb power are important strength measures for lacrosse performance and should be prioritized in training prescription for lacrosse athletes.
本研究的目的是比较美国大学体育协会（NCAA）一级男子和女子长曲棍球运动员中高贡献者和低贡献者之间的等速肌力、反向运动跳跃和纵跳变量。NCAA一级男子（N = 36）和女子（N = 30）长曲棍球运动员完成了股四头肌和腘绳肌在三种速度（60°·s、180°·s、300°·s）下的力量测试、反向运动和纵跳测试。为了确定所选下肢力量和功率特征的判别能力，根据参与者在常规赛中参加的比赛场次，将参与者分为高贡献者（男性N = 18，年龄 = 20.3±0.4岁，身高 = 183.9±5.5厘米，体重 = 90.8±5.8千克；女性N = 15，年龄 = 20.8±0.8岁，身高 = 169.3±6.7厘米，体重 = 64.1±7.2千克）或低贡献者（男性N = 18，年龄 = 19.5±0.2岁，身高 = 184.1±5.6厘米，体重 = 87.9±8.1千克；女性N = 15，年龄 = 19.7±0.2岁，身高 = 169.8±7.0厘米，体重 = 62.9±7.7千克）。在男性队列中，高贡献者和低贡献者之间在300°·s时左腿的等速腘绳肌力量（d = 0.69）和反向运动跳跃中的峰值功率（0.68）方面观察到中度显著（p<0.05）差异。在女性队列中，高贡献者和低贡献者之间在60°·s时左腘绳肌的等速肌力方面观察到较大（0.87）显著差异（p<0.05）。腘绳肌力量和下肢功率是长曲棍球表现的重要力量指标，在长曲棍球运动员的训练处方中应予以优先考虑。
