Abstract

Stretching is common, yet little work has explored the influence of stretch intensity and sex differences in response to stretching. We investigated the acute effect of static pectoral stretching at two intensities (110 and 120%) on pectoralis minor length, horizontal abduction range of motion (HA-ROM), and pectoralis major and minor stiffness using shear wave elastography in males and females. Twenty-four participants (N=24, 12 female; age: 25±4.6) attended two sessions where they received three sets of a randomized stretch for 30s with 30s rest between. There were no differences in pectoralis minor length, HA-ROM, or pectoralis minor or major stiffness between males and females following stretching. These findings suggest that the sexes respond similarly to static pectoral stretching. Further stretching research exploring potential sex-differences with different doses are needed
