摘要静态拉伸（SS）是一种有效的干预措施，以减少肌肉僵硬，也进行髂腰肌。髂腰肌由髂肌和腰大肌组成，其中髂肌具有较大的生理横截面积和髋关节屈曲力臂，不同肌肉降低肌肉刚度所需的静态拉伸时间不同，髂肌所需的时间尚不清楚。本研究的目的是调查所需的时间，以减少髂肌僵硬。26名健康男性参与了这项研究。进行5次1分钟髋关节伸展SS。剪切弹性模量，肌肉刚度的指数，髂肌使用超声剪切波弹性成像测量前SS和后立即每个SS。单因素重复方差分析表明，剪切弹性模量的时间的统计效果。经配对t检验和霍尔姆校正后发现，1-5个SS后的剪切弹性模量显著低于SS前。此外，5个SS后的剪切弹性模量显著低于1个SS后的剪切弹性模量。结果表明，髂肌僵硬度随SS的增加而降低，SS的增加使髂肌僵硬度进一步降低。
ABSTRACT Static stretching (SS) is an effective intervention to reduce muscle stiffness and is also performed for the iliopsoas muscle. The iliopsoas muscle consists of the iliacus and psoas major muscles, among which the former has a greater physiological cross-sectional area and hip flexion moment arm. Static stretching time required to reduce muscle stiffness can differ among muscles, and the required time for the iliacus muscle remains unclear. The purpose of this study was to investigate the time required to reduce iliacus muscle stiffness. Twenty-six healthy men participated in this study. A 1-min hip extension SS was performed five times. Shear elastic modulus, an index of muscle stiffness, of the iliacus muscle was measured using ultrasonic shear wave elastography before SS and immediately after each SS. One-way repeated analysis of variance showed a statistical effect of time on the shear elastic modulus. A paired t-test with Holm adjustment revealed that the shear elastic moduli after 1–5 SS were statistically lower than that before SS. In addition, the shear elastic modulus after 5 SS was statistically lower than that after 1 SS. The results suggested that the stiffness of the iliacus muscle decreased with 1-min SS and further decreased with 5-min SS.
