Brief Summary

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

The study is planned to be conducted in 2025. The methods used in the study are non-invasive methods. The study groups will perform 1 to 3 static stretching sessions per week. The number of series per session will be from 1 to 3. The static stretching time of the back band in the series will be from 20 s to 60 s. The total stretching time per week will be from 45 s to 135 s. The break between series will be 45 s, and the duration of the intervention will be from 6 to 8 weeks. During stretching, the subject maintains a maximum bend with straight knee joints for a specified time. Before starting the study, participants will undergo a toe-to-floor test to assess the flexibility of the back band. The test will be repeated after the intervention. The aim of the study is to determine the minimum effective dose of static stretching. Currently, anecdotal evidence suggests that this dose is 90 seconds of static stretching per week.

The study does not involve any likelihood of harm to study participants as a result of participating in the study.

Study Groups

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

Streching group

The group performed one training session per week consisting of 2 sets of static stretching

Group Type EXPERIMENTAL

Training - static streching

Intervention Type OTHER

The intervention group performed one training session per week. Each training session consisted of 2 series of static stretching of the back band. The rest time between series was 45 s. The intervention lasted 6 weeks.

Control group

Only tests were performed in the group, no intervention was introduced

Group Type NO_INTERVENTION

No interventions assigned to this group
