Abstract

The purpose of this study was to examine the reliability of the acute effect of stretch on vertical jump performance. Twenty-four subjects completed eight trials. In each trial warm-up, three pre-stretch jumps, stretching, and three post-stretch jumps were completed. Intraclass correlation coefficients (ICC) were used to evaluate the reliability of the stretch impact on vertical jumping across trials. While pre-stretch and post-stretch jumps were highly reliable (ICC=0.99), the difference from pre-stretch to post-stretch was not (ICC=0.07). The stretch impact on vertical jump may not be reliable for subjects across trials.
