Brughelli, M、Cronin, J、Mendiguchia, J、Kinsella, D 和 Nosaka, K。曾有腿筋受伤的澳式足球运动员在跑步过程中，对侧腿部的动力学和运动学变量存在缺陷。 J Strength Cond Res 24(9): 2539-2544, 2010 - 运动过程中下肢之间的对侧腿缺陷被认为会增加受伤风险并影响表现。本研究的目的是量化未受伤和曾受伤的澳式橄榄球 (ARF) 运动员在跑步过程中腿部缺陷的严重程度。这些球员包括一组未受伤的 ARF 球员（n = 11）和一组之前受伤的 ARF 球员（n = 11；仅腿筋受伤）。受伤组（IG）的球员在过去2年中至少有1次急性腿筋损伤。未受伤球员（NIG）的腿被分为右腿和左腿，而受伤球员的腿被分为受伤或未受伤。运动员在非机动力量跑步机上以最大速度 (Vmax) 的 80% 左右运行。对于 NIG，右腿和左腿之间的任何变量都没有显着差异。对于 IG，受伤腿和未受伤腿之间唯一显着差异 (p < 0.001) 的变量是水平力（175 +/- 30 与 326 +/- 44 N）。此外，与 NIG 中的任何一条腿相比，未受伤腿 (IG) 中的水平力显着更大（19.2% 和 20.5%），而与 NIG 中的任何一条腿相比，受伤腿 (IG) 中的水平力显着较小（31.5% 和 32.7%）。在本研究中，以前腿筋受伤的运动员在以次最大速度跑步时，对侧腿部在水平方向上有缺陷，但在垂直方向上没有缺陷。
Brughelli, M, Cronin, J, Mendiguchia, J, Kinsella, D, and Nosaka, K. Contralateral leg deficits in kinetic and kinematic variables during running in Australian rules football players with previous hamstring injuries. J Strength Cond Res 24(9): 2539-2544, 2010-Contralateral leg deficits between lower limbs during athletic movements are thought to increase the risk of injury and compromise performance. The purpose of this study was to quantify the magnitude of leg deficits during running in noninjured and previously injured Australian Rules football (ARF) players. The players included a group of noninjured ARF players (n = 11) and a group of previously injured ARF players (n = 11; hamstring injuries only). The players in the injured group (IG) had at least 1 acute hamstring injury in the previous 2 years. The legs of the noninjured players (NIG) were classified as right and left, whereas the legs of the injured players were classified as injured or noninjured. The players ran on a nonmotorized force treadmill at approximately 80% of their maximum velocity (Vmax). For the NIG, there were no significant differences between right and left legs for any of the variables. For the IG, the only variable that was significantly (p < 0.001) different between the injured and noninjured leg was horizontal force (175 +/- 30 vs. 326 +/- 44 N). Furthermore, horizontal force was significantly greater in the noninjured leg (IG) in comparison with either legs in the NIG (19.2% and 20.5%) and significantly less in the injured leg (IG) in comparison with either legs of the NIG (31.5% and 32.7%). In the present study, athletes with previous hamstring injuries had contralateral leg deficits in horizontal but not vertical force during running at submaximal velocities.
