 note = {Subjects were 15 female university track and field athletes. In an attempt to improve athletic performance， subjects were instructed to throw a medicine ball and put a shot with and without vocalization. In addition，grip strength was measured in order to clarify the effects of vocalization on throwing. The results showed that significant differences between with and without vocalization were observed for the standing shot put，front medicine-ball throw，and chest medicine ball throw. A significant difference between with and without vocalization was observed for the grip strength of the nondominant hand. Furthermore，among the subjects with shot put and medicine ball throwing distances shorter than the median value，there was a correlation between grip strength and distance: the greater the grip strength，the longer the throwing distance. These findings suggest that vocalizing during routine practices improves athletic performance.},
