Pre-activity stretching is commonly performed by athletes as part of their warm-up routine. However, the most recent literature questions the effectiveness of pre-activity stretching. Some literature suggests that pre-activity stretching hinders athletic performance, while others suggest that stretching does not affect performance. Since a clear answer has not yet been determined on pre-activity stretching, this study was designed to investigate the acute effects of static vs. ballistic stretching on vertical jump performance, and torque and power output of the quadriceps and hamstrings, and to compare the effects of stretching between genders. The goal was to determine if pre-activity stretching is beneficial or detrimental to sports performance. The results of this study revealed that a practical duration of 90 seconds of stretching did not affect VJ or torque output of the quadriceps and hamstrings. The results of this study will allow strength coaches to properly advise their athletes on pre-activity stretching.
