The effects of static and dynamic stretching exercises on the lower extremity performance

The research study aimed to investigate the effects of static and dynamic stretching exercises on lower extremity performance. The study involved a sample of participants divided into two groups: five in the static stretching group and five in the dynamic stretching group. Specifically, the research aimed to (1) determine the mean lower extremity performance (vertical jump height) of the participants before and after the intervention of static and dynamic stretching; (2) identify the significant difference between the pre-test and post-test outcomes of lower extremity performance when static stretching is applied; and (3) identify the significant difference between the pre-test and post-test outcomes of lower extremity performance when dynamic stretching is applied. Participants performed specific stretching routines before engaging in lower extremity exercises, and measurements of maximum performance—including strength, power, and flexibility—were recorded before and after the interventions. The results were analyzed to assess the impact of both stretching types on lower extremity performance. Static stretching showed positive effects on strength, power, and flexibility, which can enhance overall performance. In contrast, the findings suggest that dynamic stretching may negatively impact lower extremity performance when performed before activities that require explosive movements or high-intensity efforts. Therefore, it is advisable to limit the use of dynamic stretching in pre-exercise routines and instead incorporate it into post-exercise or cooldown sessions.
