BackgroundPrevious research has shown that muscle imbalances may be an important risk factor for lower limb injuries in runners. No studies have evaluated hip musculature imbalance in sprinters. Identifying pre-season strength and imbalances of the hip gluteal musculature can have an important impact on injury prevention within this population.ObjectiveTo describe the muscle performance and imbalances between limbs related to the hip extensor, external rotators and abductors muscles in sprinters.DesignAthletes were assessed during the pre-season period. Muscle function performance of the hip extensors, external rotators and abductors were tested.ParticipantsAll participants (n=69) were federated at the Spanish athletics federation and involved in high-level track and field training sessions (minimum 5 sessions per week) for at least the last 3 years. All of them had undertaken similar training demands in the past.InterventionsWe measured the maximum number of repetitions without compensatory movements of each leg during the straight knee bridge exercise (test 1), hip external rotation in prone (test 2) and hip abduction in side-line (test 3). Data analysis and comparison in between limbs were calculated.ResultsNo significant differences in between limbs were observed in all three tests (p
