Lumbar stabilization exercises are aimed at control of forces that may cause postural instability and at maintenance of normal spinal posture for maximum conscious or unconscious adaptation in response to external loads. Keywords : Abdominal oblique muscles, Electromyography, Exercise, Hip, Lower extremity These findings may be applicable within the clinical field for selective trunk and lower extremity muscle activation and advanced rehabilitation purposes. ConclusionsĮS and BF muscle activity increases were observed with hip adduction and increased GM activity was observed with hip abduction. For left EO, a significant increase was observed in the IHAD condition compared to the general bridge condition ( p<0.05). For bilateral GM, there was a significant increase in muscle activity in the IHAB condition compared to the general bridge condition ( p<0.05) and there was a significant increase in muscle activity in the IHAB condition compared to IHAD condition ( p<0.05). Resultsįor bilateral ES and BF, there was a significant increase in muscle activity in the IHAD condition compared to the general bridge and IHAB condition ( p<0.05). Subjects performed each of the three bridge conditions three times in random order and mean values were obtained. The muscle activities of bilateral erector spinae (ES), gluteus maximus (GM), biceps femoris (BF), and external oblique (EO) muscles during the bridge exercises were measured using sEMG. All subjects randomly performed three different bridge conditions as follows: general bridge exercise, isometric hip abduction (IHAB) with a blue Thera-band (Hygenic Corp., USA), and isometric hip adduction (IHAD) with a Swiss ball (Hygenic Corp.). DesignĪ total of 20 healthy young adults (10 males, 10 females) voluntarily participated in this study. To investigate the effect of performing three different bridge exercise conditions on the activities of four different muscles using surface electromyography (sEMG) in healthy young adults.
