用不喜欢的腿踢球在澳大利亚足球中很重要，在橄榄球规则中也越来越重要。本研究的目的是为了检验偏好和非偏好的腿踢法之间的差异。17名优秀的澳大利亚足球运动员用首选腿和非首选腿进行踢球。Optotrak Certus收集了踢球腿和骨盆的运动学数据（200hz），从踢球腿的脚趾到球接触。脚部速度、膝关节和小腿接触球时的角速度以及骨盆活动范围均显著大于选择腿（P < 0.05）。相比之下，非首选腿的髋部和大腿接触球时的角速度和髋部活动范围明显更大。这表明了不同的运动模式，首选腿踢更多地利用骨盆、膝盖和小腿，而非首选腿踢相对更多地依赖于臀部和大腿（P < 0.05）。造成这种差异的原因可能是由于锁定自由度或非首选腿的次优排序。Ball（2008）确定的股骨-膝关节连续体在本研究中也很明显。研究结果对训练非偏好踢腿和预防伤害具有启示意义。
Kicking with the non-preferred leg is important in Australian Football and becoming important in the rugby codes. The aim of this study was to examine differences between preferred and non-preferred leg kicking in the drop punt kick. Seventeen elite Australian Football players performed kicks with the preferred and non-preferred leg. Optotrak Certus collected kinematic data of the kick leg and pelvis (200 Hz) from kick leg toe-off until ball contact. Foot speed, knee and shank angular velocity at ball contact, and pelvis range of motion were significantly larger for the preferred leg (P < 0.05). In contrast, hip and thigh angular velocity at ball contact and hip range of motion were significantly larger for the non-preferred leg. This indicates different movement patterns, with preferred-leg kicks making greater use of the pelvis, knee, and shank while non-preferred leg kicks rely relatively more on the hip and thigh (P < 0.05). Reasons for this difference might be due to locking degrees of freedom or sub-optimal sequencing in the non-preferred leg. The thigh-knee continuum identified by Ball (2008) was also evident in this study. Findings have implications for training non-preferred leg kicking for performance and injury prevention.
