Stretching in the warm-up was been shown to decrease several muscular performance variables, but the dose-response of this effect is unknown. This study documented the change in isometric grip strength over ten trials in a convenience sample of young adults randomly assigned to control (n=22) or repeated bouts of 10-s static stretches of the wrist flexors (n=35). There was a significant (P<0.05) difference="" in="" the="" change="" in="" mean="" normalized="" grip="" strength="" between="" the="" control="" and="" stretching="" groups="" that="" was="" not="" significantly="" different="" across="" gender.="" grip="" strengths="" in="" the="" control="" group="" were="" consistent="" with="" a="" linear="" trend,="" while="" the="" grip="" strengths="" in="" the="" stretching="" group="" declined="" in="" a="" logarithmic="" fashion="" to="" 88.8%="" with="" 100 s="" of="" stretching.="" statistically="" significant="">P<0.05) differences="" in="" normalized="" grip="" strength="" between="" the="" two="" groups="" appeared="" after="" 40 s="" of="" stretching.="" meaningful="" decreases="" in="" isometric="" grip="" strength="" following="" static="" stretching="" are="" likely="" to="" appear="" in="" young="" adults="" following="" 20–40 s="" of="" static="">
