Abstract

Accelerations and deceleration are key elements of random intermittent multidirectional sports, including Rugby League. Deceleration performance has received far less investigation than acceleration, leaving its biomechanical and neuromuscular determinants underexamined. Contributions from hip musculature are unknown hence, the purpose of this study was to investigate the relationship between maximal horizontal deceleration performance and hip musculature strength. Thirteen female high performance rugby league athletes (mean ± SD: age = 18.92±1.93 years, height = 164.23±5.46 cm, body mass = 70.21±11.27 kg) completed a 30-meter maximal sprint followed by a maximal linear deceleration test. Maximal deceleration test consisted of a 20-meter maximal acceleration followed by a maximal horizontal deceleration and backpedal to the 20-meter line and was assessed by the time and distance (TTS and DTS, respectively) athletes needed to come to a complete stop. Hip flexors and extensors and hip abductors and adductors were tested in concentric and eccentric motion using an isokinetic dynamometer. Isokinetic dynamometry tested both, dominant and non dominant legs, at 60º/s for the hip flexion and extension test and at 30º/s for the hip abduction and adduction test. Pearson’s correlation coefficients were calculated together with coefficient intervals (90%) to determine if relationships exist between hip strength and deceleration performance. No correlations were found between any of the strength measurements and maximal horizontal deceleration metrics providing novel insights into hip mechanics while maximally decelerating. In conclusion, hip strength might not play a pivotal role within maximal linear deceleration performance specifically, but hip musculature must be trained to support the knee joint leading to an effective and safe deceleration performance.
