Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Group 1

10 sedentary women

Group Type EXPERIMENTAL

Static streching exercise

Intervention Type 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.

Group 2

10 sedentary men

Group Type EXPERIMENTAL

Static streching exercise

Intervention Type 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.
