The study was designed as a single-blinded, before-and-after clinical trial. Main outcome measures included pain, functional ability, hip range of motion (ROM), hip abductor and adductor muscle strength, and successful return to sports activity.Results Eleven athletes (78.57%) returned to their sports activities in a mean time of 14.2 weeks (range, 10-20 weeks). Visual analogue scale pain score, hip abductor and adductor muscles strength, and function scores improved significantly. Although hip abduction ROM did not show any significant changes (p = 0.609), the extent of progress in the hip internal rotation ROM was significant (p = 0.001). The ratio of hip adduction to abduction strength did not change significantly (p = 0.309 for the isometric and p = 0.957 for the eccentric ratio).Conclusions Exercise therapy according to the Holmich programme may be an effective treatment for LSAGP. However, more emphasis should be paid to the hip adductor muscles’ eccentric strength.Trial registration number IRCT2016080829269N1.
