Abstract

Objectives: This study investigated the acute effects of dynamic stretch (DS) duration on the muscle stiffness of the ankle plantar flexor using shear wave ultrasound elastography.

Methods: Eighteen healthy young participants were enrolled in this study. DS with one set (DS1) or four sets (DS4) of 30 s each was performed randomly. Shear wave velocity in the medial gastrocnemius (MG) was measured before and after DS to assess muscle stiffness of the MG.

Results: Two-way repeated-measures analysis of variance (condition × time) showed a significant interaction with the shear wave velocity (p = 0.02). Shear wave velocity significantly decreased after the DS4 than before (before:3.09 ± 0.59 m/s; after: 2.86 ± 0.43 m/s). However, no significant differences were observed in shear wave velocity between before and after DS1 (before: 2.96 ± 0.56 m/s; after: 3.19 ± 0.56 m/s). There were no significant differences in shear wave velocity at baseline condition. After the intervention, significantly lower shear wave velocity was observed in DS4 than in DS1.

Conclusions: The results of this study demonstrate that DS with four sets of 30 s effectively decreased the muscle stiffness of the MG.

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.
