项目摘要

In the present research project, I defined flexibility as the range of motion (ROM) of the joint, and carried out a series of studies with the following three aims, i.e., 1) to elucidate determinants of ROM, with respect to musculotendinous properties, 2) to clarify gender differences and effects of growth and aging on ROM and their determinants, and 3) to investigate the plasticity of ROM. For these aims, I developed a system with which passive ROM was measured in a well-controlled loading condition and extensibility of the muscle-tendon unit was measured in vivo. Throughout the series of studies, I focused on ankle plantar-and dorsi-flexion ROM by studying behavior of the triceps surae and tibialis anterior muscles. The following findings were obtained. 1) It was shown that ROM should be evaluated both in passive and active conditions, and that muscle size, strength, and elastic properties of the muscle-tendon unit were selected as determinants of passive and active ROM. 2) There was a gender difference in ROM (women larger than men) that was related particularly with extensibility of the tendon, but the relationship was a function of age. 3) Static stretching of the muscles resulted in an increase in ROM that was accompanied by further elongation of tendon but not of muscle fibers. Bed rest induced similar changes in ROM and tendon properties. Furthermore, the interdependence among muscle size, strength, architecture, and musculotendinous mechanical properties was studied in detail. Studies on the relationship between deformation of the muscle-tendon unit induced by passive lengthening, active contractions and joint torque indicated the possibility of plasticity of musculotendinous mechanical properties, suggesting potentials of these procedures as the way to improve ROM.

在本研究项目中，我将灵活性定义为关节的运动范围（ROM），并进行了一系列研究，以下三个目标（即1）进行了一系列研究，以阐明ROM的决定因素，以阐明肌肉齿状性能，2）阐明了ROM及其对确定性的生长及其对塑料的性别差异和影响的性别差异和效果。对于这些目的，我开发了一个系统，该系统在该系统中以良好的控制载荷条件进行了测量，并在体内测量了肌肉弯曲单元的可扩展性。在整个研究中，我通过研究三头肌和胫骨前肌的行为来关注脚踝足底和背屈肌。获得了以下发现。 1）结果表明，应在被动和主动条件下对ROM进行评估，并选择肌肉刺激单元的肌肉大小，强度和弹性特性作为被动和主动ROM的决定因素。 2）ROM的性别差异（女性大于男性）尤其与肌腱的可扩展性有关，但这种关系是年龄的函数。 3）肌肉的静态拉伸导致ROM的增加，伴随着肌腱的进一步伸长，但没有肌肉纤维。床休息引起了ROM和肌腱特性的类似变化。此外，详细研究了肌肉大小，力量，结构和肌肉齿状机械性能之间的相互依赖性。关于被动延长，主动收缩和关节扭矩引起的肌肉弯曲单位变形之间的关系的研究表明，肌肉座的机械性能的可塑性可能表明这些程序的潜力是改善ROM的方式。
