The Relationship between Passive Lower Limb Flexibility and Kinematic Determinants of Split Leap Performance in Rhythmic Gymnastics

Abstract

Rhythmic gymnastics requires use of a considerable degree of flexibility and strength. These two abilities allow gymnasts to perform better jumps and leaps. According to recent rules all jumps/leaps must have a defined and fixed shape and height of the jumps /leaps should be sufficient to show corresponding shape. Split leap (SpL) is one of the most preferred elements in rhythmic gymnastics. Purpose of current study was to identify the relationships among kinematic components of SpL and passive flexibility applied during forward split (FSF) and backward split (BSF). 11 rhythmic gymnasts participated in current study. Split balance without help of the hands were performed to evaluate FSF and to evaluate BSF gymnasts hold their penché position. Gymnasts performed SpL with their preferred leg. All tests recorded with a camera (120 frames per second). Spearman Correlation Analysis were performed to explain the relationships between variables. FSF was found to be significantly correlated to BSF (r=0.629; p=0.038), BSF and flight angle showed significant correlation (r=0.692; p=0.018). As a result, it can be reported that to have a better SpL performance trainers should include flexibility and plyometric exercises in the trainings.
