The lateral medicine ball throw (LMBT) test is used to evaluate the throwing action, involving the entire kinetic chain and the principle of force transfer, with association between the strength of the lower limb and trunk muscles and the lower limb kinematics. The LMBT to investigate the association between lower limb kinematics and hip and trunk muscle strength.
This was a cross-sectional study with 84 healthy and physically active young people. Determinations were made of the maximum isometric strengths of the hip abductor, lateral rotator, extensor, and flexor muscles, and the trunk lateral flexors and extensors. Kinematic analyses (2D) of the hip, knee, and ankle in the sagittal and frontal planes were performed during the countermovement phase of the LMBT, together with quantification of LMBT. Statistical analysis of the associations employed multiple linear regression, with α = 5%.
There were significant associations between the LMBT and the independent variables hip extensors strength, trunk flexors strength, valgus angle, and knee flexion angle and gender. The regression model presented adjusted R = 0.622.
LMBT was influenced by the trunk flexor and hip extensor muscle strengths, knee flexion kinematics, lower limb valgus in the countermovement phase, and gender.
侧向药球投掷（LMBT）测试用于评估投掷动作，涉及整个运动链和力传递原理，与下肢和躯干肌肉力量以及下肢运动学之间存在关联。LMBT 用于研究下肢运动学与髋关节和躯干肌肉力量之间的关联。
这是一项横断面研究，共有 84 名健康且活跃的年轻人参与。确定了髋关节外展肌、外侧旋转肌、伸肌和屈肌以及躯干侧屈肌和伸肌的最大等长力量。在 LMBT 的反向运动阶段，对髋关节、膝关节和踝关节在矢状面和额状面进行了运动学分析（2D），并对 LMBT 进行了量化。采用多元线性回归分析了关联，α=5%。
LMBT 与独立变量髋关节伸肌力量、躯干屈肌力量、外翻角度和膝关节屈曲角度以及性别之间存在显著关联。回归模型的调整 R=0.622。
LMBT 受到躯干屈肌和髋关节伸肌力量、反向运动阶段膝关节屈曲运动学、下肢外翻、性别等因素的影响。
