Abstract

Static stretching routines may have the potential to increase power, flexibility, and speed. Therefore the purpose of this study is to determine whether or not performing static stretching over a six-week period will improve 40-yard dash time, vertical jump height, and range of motion in lower extremities for collegiate men’s lacrosse players. To test for this relationship, this study implemented a six-week static stretching routine for male collegiate lacrosse players. Participants in the experimental group were instructed to perform a lower-leg stretching protocol three times a week while the control group did not participate in any stretching. Speed was assessed via a 40-yard dash, power was assessed via a vertical-jump test, and flexibility assessed via a sit and reach test and joint flexibility via goniometer measurements. It was hypothesized that improved power, flexibility, and speed would be seen in the experimental group (six-week static stretching routine) compared to the control group (no stretch). Following the six-week experimental condition treatment, no significant results were found between the two groups. Main effects were found in the vertical jump (p=0.052, pre: 25.5±2.7, post: 24.6±2.9) and the 40-yard dash (p=0.000, pre:5.20±.29, post:5.31±.26). Sit-and-reach showed marginally significant results with an increase in flexibility for the experimental group and a decrease in flexibility in the control group. These results demonstrated the benefit to flexibility a longitudinal static stretching routine has as well as demonstrated that longitudinal static stretching does not improve performance on high power activities.
