The acute and prolonged effects of 20-s static stretching on muscle strength and shear elastic modulus.

ABSTRACT: INTRODUCTION:Static stretching (SS) is commonly performed as part of warm-up routine. However, only few previous studies have reported on the effects of short-duration SS, which is often used in the sports field. The purpose of this study was to investigate the acute and prolonged effects of 20-s SS on isokinetic contraction muscle strength, range of motion (ROM), and the shear elastic modulus. METHOD:Twenty male volunteers participated in this study. The ROM and both concentric and eccentric contraction muscle strengths were measured using a dynamometer. In addition, the shear elastic modulus of medial gastrocnemius muscle in dominant leg was measured by ultrasonic shear wave elastography. The participants visited the laboratory on four occasions each separated by >3 days. The first visit
