Although the kicking skill is influenced by limb dominance and sex, how a previous hamstring injury affects kicking has not been studied in detail. Thus, the objective of this study was to evaluate the effect of sex and limb dominance on kicking in limbs with and without a previous hamstring injury.
Forty-five professional players (males: N.=19, previously injured players=4, age=21.16±2.00 years; females: N.=19, previously injured players =10, age= 22.15±4.50 years) performed 5 kicks each with their preferred and non-preferred limb at a target 7m away, which were recorded with a three-dimensional motion capture system. Kinematic and kinetic variables were extracted for the backswing, leg cocking, leg acceleration and follow through phases.
A shorter backswing (20.20±3.49% vs. 25.64±4.57%), and differences in knee flexion angle (58±10º vs. 72±14º) and hip flexion velocity (8±0 rad/s vs. 10±2 rad/s) were observed in previously injured, non-preferred limb kicks for females. A lower peak hip linear velocity (3.50±0.84 m/s vs. 4.10±0.45 m/s) was observed in previously injured, preferred limb kicks of females. These differences occurred in the backswing and leg-cocking phases where the hamstring muscles were the most active. A variation in the functioning of the hamstring muscles and that of the gluteus maximus and iliopsoas in the case of a previous injury could account for the differences observed in the kicking pattern.
Therefore, the effects of a previous hamstring injury must be considered while designing rehabilitation programs to re-educate kicking movement.
尽管踢球技巧受肢体优势和性别影响，但既往腘绳肌损伤如何影响踢球尚未得到详细研究。因此，本研究的目的是评估性别和肢体优势对有或无既往腘绳肌损伤肢体踢球的影响。
45名职业球员（男性：N = 19，既往受伤球员 = 4，年龄 = 21.16±2.00岁；女性：N = 19，既往受伤球员 = 10，年龄 = 22.15±4.50岁）用其优势腿和非优势腿向7米外的目标各踢5次，并用三维运动捕捉系统进行记录。提取后摆、腿部预摆、腿部加速和随球动作阶段的运动学和动力学变量。
在既往受伤的女性非优势腿踢球中，观察到后摆较短（20.20±3.49% 对 25.64±4.57%），以及膝关节屈曲角度（58±10° 对 72±14°）和髋关节屈曲速度（8±0 rad/s 对 10±2 rad/s）存在差异。在既往受伤的女性优势腿踢球中，观察到髋关节线性速度峰值较低（3.50±0.84 m/s 对 4.10±0.45 m/s）。这些差异出现在腘绳肌最活跃的后摆和腿部预摆阶段。既往受伤情况下，腘绳肌以及臀大肌和髂腰肌功能的变化可能是踢球模式差异的原因。
因此 在设计用于重新训练踢球动作的康复计划时，必须考虑既往腘绳肌损伤的影响。
