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

Öz

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.

Ritmik Cimnastikte Pasif Alt Ekstremite Esnekliği ve Split Sıçramanın Kinematik Belirleyicileri Arasındaki İlişki

Öz

Ritmik cimnastik önemli derecede esneklik ve kuvvet gerektirir. Bu iki beceri cimnastikçilerin sıçrama ve atlamaları daha iyi yapmalarını sağlar. Son kurallara göre, sıçramalar/atlamalar iyi tanımlanmış şekle ve ilgili şekli gösterecek yüksekliğe sahip olmalıdır. Split sıçrama (SpL), ritmik cimnastikte sıklıkla kullanılan elementlerden biridir. Çalışmanın amacı, Split sıçramanın kinematik komponentleri ile öne (FSF) ve arkaya (BSF) uygulanan pasif esneklik arasındaki ilişkiyi belirlemektir. Çalışmaya 11 ritmik cimnastikçi katılmıştır. FSF için el yardımı olmadan öne split denge uygulanmış ve BSF penché pozisyonunun gerçekleştirilmesi ile belirlenmiştir. Cimnastikçiler tercih ettikleri bacakları ile SpL elementini uygulamışlardır. Tüm testler saniyede 120 kare çeken kamera ile kaydedilmiştir. Değişkenler arasındaki ilişkileri açıklamak için Spearman korelasyon analizi kullanılmıştır. FSF ve BSF istatistiksel olarak anlamlı ilişki göstermiştir (r=0.629; p=0.038), BSF ve uçuş açısı arasında anlamlı ilişki bulunmuştur (r=0.692; p=0.018). Sonuç olarak, daha başarılı SpL tekniği/performansı için antrenörlerin antrenmanlarda esneklik ve pliometrik antrenmanlara yer vermesi önerilir.
