Comparison of the Effects of Static Stretching and Full Range of Motion Strength Training on Posterior Band Flexibility

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.

Inclusion Criteria: Participants were required to be ≥18 years of age and free from musculoskeletal injuries or surgical procedures involving the lower extremities or trunk within the previous six months. Exclusion Criteria: Participants were excluded if they were \
