About

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.

51 participants in 3 patient groups

Control group

No Intervention group

Description:

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

Streching group

Experimental group

Description:

The group performed one training session per week consisting of 2 sets of 60 seconds of static stretching

Treatment:

Other: Streching group

Strength training group

Experimental group

Description:

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.
