The Functional Movement Screen has been a very popular tool for assessing athlete’s movements and predicting future risk of injury. In the hierarchy of this screen, the active straight leg raise reigns supreme. They have shown that improvements in this movement correlate to improvements in other movements but not vise versa. It is important to find a way to quickly improve this functional movement, so it can be utilized in group settings to help potentially reduce the risk of injury in athletes. The findings of this study will serve to be valuable in sports injury and improvement in performance. The study investigated two ways of improving the active straight leg raise, a partner assisted passive stretch and an active stretch. The active straight leg raise was assessed three times on the right leg and then a stretch was performed. The active straight leg raise was then assessed three times again. The change between the pre and post stretch active straight leg raise was analyzed. When analyzed against the control group both stretch groups showed statistically significant improvements in the active straight leg raise. When both stretch groups were analyzed against each other, it was shown that there was no significant difference between the two. These findings are impactful because the active straight leg raise has been a good predictor of the likelihood of lower body injuries. Finding a way that can quickly improve this screen may have an impact on athlete health. These two stretches were shown to be effective in just one session. Two future areas of study would be looking towards the lasting effect of the stretches and if the stretches are performed consistently what are their effects.
