Overview

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.

Outcomes

Primary Outcomes

Flexibility

Flexibility was assessed using a modified stand-and-reach test. The participants stood with their feet shoulder-width apart and knees fully extended, then performed a forward bend, reaching as far as possible while maintaining straight legs. To measure the extent of their reach, a custom-built box was used. The box had the following dimensions: a length of 40 cm, a width of 45 cm, and a height of 35 cm. Each participant performed the test once. The same test was repeated after the 6-week intervention period to determine any improvements in flexibility.

Time frame: From registration to completion of the study, the duration is up to 8 weeks
