The aim of this study is to compare the immediate effects of lower extremity static stretching exercises on vertical jump in sedentary individuals based on gender.
The study was conducted on 10 female (Group 1) and 10 male (Group 2) university students. The vertical jump height (VJH) of the individuals who agreed to participate in the study was measured with a wireless jumping platform. After the initial evaluations, lower extremity static stretching exercises targeting the M. Gastrocnemious and M. Hamstring muscles were applied to the participants in both groups. The VJH of the participants was re-evaluated immediately after the application. Both pre-post evaluations and female-male comparison evaluations will be performed for the statistical analysis of the data.Statistical analysis will be performed with SPSS 24.0 program. If the data is parametric, paired sample t-test will be used for within-group evaluation; independent sample t-test will be used for between-group evaluation. If the data is non-parametric, Wilson test will be used for within-group evaluation and Mann Whitney U test will be used for between-group evaluation.

| Static streching exercise | Other | Static stretching exercises were applied to the M. Gastrocnemious and M. Hamstring muscle groups for both groups. The exercises were applied as a set, with three repetitions for 15 seconds on each leg, with a 20-second rest between repetitions. Static stretching was applied by slowly stretching the relevant muscle group to the point of sensitivity, without straining the pain threshold, and waiting in that position. All stretching exercises lasted an average of 6 minutes. |

| Vertical jump height | DSY was measured with a wireless jumping platform (Ezejump, Australia). Participants were subjected to three squat jump tests on this platform with free intervals between repetitions and the maximum value obtained from the test was recorded as the vertical jump height. | at baseline and immediately after the lower extremity static stretching exercise program |
