The objective of this study was to explore the effects of static and dynamic hamstring muscles stretching on kinematics and esthetics of grand battement (high velocity kicks) in adolescent recreational dancers. Sixteen participants were assessed before and immediately after both stretching modalities. Kinematics of movement was measured by an optoelectronic system and esthetics was scored by a jury of professional dancers. Both stretching modalities led to significant kinematic differences compared with without stretching. Significant linear correlations between kinematic parameters and esthetic scores have been observed: improving dancers' physical performances has noticeable impact on the perception of their movements.

青少年静态和动态腿筋伸展后大发力的运动学和美学。

这项研究的目的是探讨静态和动态绳肌拉伸对青春期休闲舞者大发力运动（高踢腿）的运动学和美学的影响。在两种伸展方式之前和之后立即评估了十六名参与者。运动的运动学是由光电系统测量的，而美学是由专业舞者组成的评审团进行评分的。与未拉伸相比，两种拉伸方式均导致明显的运动学差异。运动参数和美学分数之间存在显着的线性相关性：提高舞者的身体表现对他们的动作感知有显着影响。
