Abstract :The aim was to examine the muscle activation levels of Gluteus Medius and Adductor Longus during non-weight-bearing exercises with and without core activation. 13 healthy participants (20.23±1.71 years) were included in the study. Surface EMG (Noraxon Ultium USA, Inc., Scottsdale, AZ) was used to measure maximum voluntary isometric contraction. Muscle activation measurements were made during external thrust for the Gluteus Medius and internal thrust for the Adductor Longus with and without core activation. The exercises were performed in supine and crawling positions. Each measurement was made for 5 seconds and in 3 repetitions. The average of 3 measurements for each position and exercise was calculated and used in statistical analysis. Moderate muscle activation was found in the Gluteus Medius in the supine (29.84±17.48%) and crawling (30.47±12.72%) positions, while high muscle activation was found in the Adductor Longus in the supine (59.15±21.83%) and crawling (58.99±25.35%) positions. Core activation decreased the activity of the Gluteus Medius and Adductor Longus in both positions (p 0.05). Core activation decreased Gluteus Medius and Adductor Longus muscle activation regardless of position. According to this study, adding core activation to exercises to increase hip strength is not appropriate.
