CHANGES IN SUPPORT MOMENT AND MUSCLE ACTIVATION FOLLOWING HIP AND TRUNK NEUROMUSCULAR TRAINING: THE HIP AND ACL INJURY RISK
Keywords: GLUTEAL, UNPLANNED SIDESTEPPING, INTERVENTION
AbstractThis study investigated lower limb muscular activation strategies following an 8-week body-weight based training intervention focused on the dynamic control of the hip/trunk. Muscle activation, support moment and frontal plane knee moments of elite female hockey players (n=13) were measured during unplanned sidestepping pre/post training. Post-training, gluteal muscle activation increased (+10%;p=0.006). There was no change in support moment or frontal plane knee moments however, the contribution of hip extension to total support moment increased (+10%;d=0.56) following training. Hip/trunk neuromuscular training is effective in improving hip neuromuscular activation, allowing athletes to more effectively utilise their hip to generate their support moment, which may prevent dangerous ‘dynamic valgus’ knee postures during sidestepping sporting tasks.
