Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
A stretch with a lower extremity was analyzed by an expert physiotherapist. This stretch was performed in conventional hip extension, in a half-knee position, but adding a posterior pelvic tilt position (posterior pelvic tilt group). Stretching was performed in two sets of 30 seconds with 30 seconds of rest between sets, performed individually for each subject (one-on-one) at the research center. Intervention throughout the study.

Summary
Brief summary
Achieving optimal hip extension mobility and hamstring flexibility is crucial for overall musculoskeletal health and functional movement. Limited hip extension can impact daily activities and athletic performance, while inadequate hamstring flexibility is associated with an increased risk of injury. As such, investigating effective stretching techniques to enhance hip extension and hamstring flexibility is of paramount importance. This study aims to contribute valuable insights into the comparative effectiveness of posterior pelvic tilt and hip extension stretches, with the anticipation that one of these techniques may prove superior in promoting improved hip extension and hamstring flexibility. The primary objective of this study is to compare the effects of two stretching techniques, posterior pelvic tilt and hip extension, on enhancing hip extension mobility and hamstring flexibility. We hypothesize that the posterior pelvic tilt technique will yield greater improvements in hip extension mobility and hamstring flexibility compared to the hip extension technique.
