Abstract

BACKGROUND: The effects of a long-term static stretching program on physical performance parameters have not been elucidated completely, although the effects on muscle flexibility have a consensus. OBJECTIVE: This study aimed to investigate the effect of a long-term static stretching program on physical performance and muscle properties. METHODS: Participants performed a 2-min static stretching for the ankle joint 5 times per week for 4 weeks. Physical performance and muscle properties was measured before and after the static stretching program. RESULTS: Results showed that range of motion (ROM), dynamic postural stability, and muscle hardness were positively changed, whereas other variables i.e. maximal isometric plantar flexion moment, jump heights, muscle-tendon junction displacement and its angle, were not. CONCLUSIONS: Four-week of SS program may improve ROM, dynamic postural stability, and muscle hardness without decreasing physical performance.

足底屈肌4周静态拉伸计划对身体表现和肌肉特性的影响

背景：长期静态拉伸计划对身体性能参数的影响尚未完全阐明，尽管对肌肉柔韧性的影响已达成共识。目的：本研究旨在研究长期静态拉伸计划对身体表现和肌肉特性的影响。方法：参与者每周进行5次2分钟的踝关节静态拉伸，持续4周。在静态拉伸程序前后测量身体表现和肌肉特性。结果：结果显示，运动范围（ROM）、动态姿势稳定性和肌肉硬度呈正变化，而其他变量，即最大等长跖屈力矩、跳跃高度、肌腱连接位移及其角度，则没有变化。结论：四周的SS程序可以在不降低体力的情况下改善ROM、动态姿势稳定性和肌肉硬度。

期刊介绍： Isokinetics and Exercise Science (IES) is an international journal devoted to the study of theoretical and applied aspects of human muscle performance. Since isokinetic dynamometry constitutes the major tool in this area, the journal takes a particular interest in exploring the considerable potential of this technology. IES publishes studies associated with the methodology of muscle performance especially with respect to the issues of reproducibility and validity of testing, description of normal and pathological mechanical parameters which are derivable from muscle testing, applications in basic research topics such as motor learning paradigms and electromyography. The journal also publishes studies on applications in clinical settings and technical aspects of the various measurement systems employed in human muscle performance research. The journal welcomes submissions in the form of research papers, reviews, case studies and technical reports from professionals in the fields of sports medicine, orthopaedic and neurological rehabilitation and exercise physiology.
