Summary

The study will be conducted in 2025. The methods used in the study are non-invasive methods. One study group will perform 2 series of static stretching of the posterior band once a week. The stretching time in each series will be 60s, and the duration of the intervention will be 6 weeks. The test subjects will maintain a maximum prone position with their knee joints straight for a specified period of time during the stretching. The second study group will perform full range of motion strength training in the form of 3 series of 10 repetitions of the Romanian Deadlift (RDL) once a week, with the intervention duration also being 6 weeks. Prior to the start of the study, participants will undergo a toe-to-floor test to assess posterior band flexibility. The test will be repeated again after the intervention.

Interventions

Type	Name	Description
OTHER	Strength training	The group will perform one workout per week consisting of 3 series of the "Romanian deadlift" exercise of 10 repetitions. Each repetition will be performed at a specific pace - 3s in eccentric contraction and 1s in concentric contraction. The aforementioned exercise, the Romanian deadlift, will be performed by the subjects on a platform (elevation) in order to achieve maximum range of motion.
OTHER	Streching group	The group performed one training session per week consisting of 2 sets of 60 seconds of static stretching
