摘要

目的:本研究的目的是评估静态拉伸对年轻和老年女性腘绳肌被动僵硬的急性影响。次要目的是比较两组的腘绳肌大小和质量测量(横截面积和回波强度)，并确定这些特征是否与基线时的被动僵硬有关。方法:15名年轻(23±4岁)和15名老年(73±5岁)女性接受了两种随机条件，包括对照治疗和实验性治疗，4次15秒的腘绳肌静态拉伸。使用被动膝关节伸展试验计算每次治疗前(前测)和后(后测)的被动僵硬度。超声成像测量腘绳肌横截面积和回波强度。结果:从拉伸治疗前到测试后，各组被动僵硬度下降(P=0.001)，但对照组没有(P=0.467)。老年妇女的横截面积(P=0.033)低于年轻妇女，基线(测试前)被动刚度(P=0.042-0.049)和回声强度(P=0.022)高于年轻妇女。此外，基线被动刚度与回波强度(r=0.430, P=0.018)显著相关，而与横截面积无关(r=-0.014, P=0.943)。结论:急性静态拉伸可降低年轻和老年妇女的被动僵硬。

Short-term Effects of Static Stretching on Hamstring Passive Stiffness in Young and Older Women.

Objectives: The objectives of this study were to assess the acute effects of static stretching on hamstring passive stiffness in young and older women. A secondary objective was to compare hamstring muscle size and quality measurements (cross-sectional area and echo intensity) between the two groups and to determine if these characteristics are related to passive stiffness at baseline.

Methods: Fifteen young (23±4 years) and 15 older (73±5 years) women underwent two randomized conditions that included a control treatment and an experimental treatment of four, 15-s static stretches of the hamstrings. Passive stiffness was calculated before (pre-test) and after (post-test) each treatment using a passive knee extension test. Ultrasound imaging was used to measure hamstring muscle cross-sectional area and echo intensity.

Results: Passive stiffness collapsed across group decreased from pre- to post-test for the stretching treatment (P=0.001) but not for the control (P=0.467). The older women had lower cross-sectional area (P=0.033) and greater baseline (pre-test) passive stiffness (P=0.042-0.049) and echo intensity (P=0.022) than the young women. Moreover, baseline passive stiffness was significantly related to echo intensity (r=0.430, P=0.018) but not cross-sectional area (r=-0.014, P=0.943).

Conclusion: An acute bout of static stretching decreased passive stiffness in both young and older women.

期刊介绍： The Journal of Musculoskeletal and Neuronal Interactions (JMNI) is an academic journal dealing with the pathophysiology and treatment of musculoskeletal disorders. It is published quarterly (months of issue March, June, September, December). Its purpose is to publish original, peer-reviewed papers of research and clinical experience in all areas of the musculoskeletal system and its interactions with the nervous system, especially metabolic bone diseases, with particular emphasis on osteoporosis. Additionally, JMNI publishes the Abstracts from the biannual meetings of the International Society of Musculoskeletal and Neuronal Interactions, and hosts Abstracts of other meetings on topics related to the aims and scope of JMNI.
