This study investigated the kinematic (KmS) and kinetic (KnS) strategies integrating the trunk and lower limbs to achieve maximal kicking performance. Although strategies consisting of individual joint movements or moments are known, strategies combining joint movements or moments of the trunk and lower limbs have been less studied. Fifty adult amateur soccer players were assessed. Peak joint angles and moments of the trunk, the hip of the supporting limb, the hip and knee of the kicking limb, and the velocities of the foot and ball were recorded. Canonical Correlation Analysis evaluated relationships between sets of variables. A combination of greater hip extension and knee flexion of the kicking limb, as a KmS, correlated with better kick performance (Rc = 0.60, = 0.004). Furthermore, a combination of larger moments of trunk flexion and rotation, internal rotation of the supporting hip, hip flexion, and knee extension of the kicking limb, as a KnS, were associated with better performance (Rc = 0.74, < 0.001). The explained variance was 43% for the KmS and 59% for the KnS. In amateur players, the KmS for better kick performance involved greater hip and knee movement of the kicking limb, while the KnS involved greater moments at the trunk and both lower limbs.
本研究调查了整合躯干和下肢的运动学（KmS）和动力学（KnS）策略，以实现最大踢腿性能。虽然已知由单个关节运动或力矩组成的策略，但结合躯干和下肢关节运动或力矩的策略研究较少。评估了 50 名成年业余足球运动员。记录了躯干、支撑腿的髋关节、踢腿腿的髋关节和膝关节的峰值关节角度和力矩，以及脚和球的速度。典型相关分析评估了变量组之间的关系。作为 KmS，踢腿腿更大的髋关节伸展和膝关节屈曲的组合与更好的踢腿性能相关（Rc=0.60，p=0.004）。此外，作为 KnS，躯干屈曲和旋转的更大力矩、支撑髋关节的内旋、髋关节屈曲和踢腿腿的膝关节伸展的组合与更好的性能相关（Rc=0.74，p<0.001）。KmS 的解释方差为 43%，KnS 的解释方差为 59%。在业余运动员中，更好的踢腿性能的 KmS 涉及踢腿腿更大的髋关节和膝关节运动，而 KnS 涉及躯干和两个下肢更大的力矩。
