摘要

导言：年龄引起的关节不灵活可能会导致严重的活动障碍和幸福感下降。然而，软组织的结构和机械特性与关节伸展性之间的关系仍不清楚。本研究旨在调查腘绳肌不灵活的老年男性的柔韧性、肌腱单位（MTU）硬度、肌肉超声波特征、肌力和腘绳肌柔韧性预测之间的相关性。结果结果显示，直腿抬高（SLR）与股二头肌筋膜长度（FL）伸长率（r = 0.222）、MTU 硬度（r = -0.401）和偏心力量（r = 0.219）之间存在适度相关性（均为 p < 0.05）。总之，SLR 的增加与 MTU 硬度降低、FL 拉长和偏心强度增加有关。在腿筋紧绷的老年男性中，SLR 主要受 MTU 硬度的影响，而 FL 拉伸和膝关节屈肌偏心力量的影响较小。

Correlations among flexibility, stiffness, strength and muscle ultrasound parameters in older males afflicted with hamstrings tightness

Introduction

Age-induced inflexibility may lead to significant mobility impairments and declines in well-being. However, the relationship between the structural and mechanical properties of soft tissue and joint extensibility remains unclear. This study aimed to investigate the correlation between flexibility, muscle tendon unit (MTU) stiffness, muscle ultrasound characteristics, muscle strength, and hamstring flexibility prediction in older males with hamstring inflexibility.

Methods

A hundred retired old males (mean age: 67.2 ± 4.9 years) participated in this investigation. Muscle ultrasound, flexibility, MTU stiffness, and knee flexors strength were measured in a single visit.

Results

The results revealed a modest correlation between straight leg raise (SLR) and biceps femoris fascicle length (FL) elongation (r = 0.222), MTU stiffness (r = -0.401), and eccentric strength (r = 0.219) (all p < 0.05). MTU stiffness, eccentric strength, and FL elongation collectively explained 24.8% of the variance in SLR prediction, while deep fascia thickness predicted MTU stiffness with a variance of 6.4%.

Conclusion

In summary, increased SLR was associated with lower MTU stiffness, lengthened FL, and higher eccentric strength. SLR was primarily predicted by MTU stiffness, with lesser contributions from FL elongation and knee flexor eccentric strength in older males experiencing hamstring tightness.
