The purpose of the present study was to investigate the effects of stimulative (energizing) and sedative (relaxing) music on grip strength. A 2 x 3 (gender x condition) repeated-measures analysis of variance and post hoc tests showed that participants (N = 50) evidenced higher grip strength after listening to stimulative music (M = 43.94 kg.force) than after sedative music or a white noise control condition. Sedative music yielded lower scores than white noise. Men evidenced higher grip strength than women, but there was no interaction between gender and music condition. It was concluded that a simple motoric task such as grip strength provides a sensitive measure of psychophysical responses to music.
