Abstract
[Purpose] This study investigated the effect of push-up exercise with hip adduction on the COP deviation and SA and L1 spinal muscle activation. [Subjects] Twelve males aged 20–30 years were recruited. [Methods] We measured the COP deviation and SA and L1 spinal muscle activities during push-up exercise with and without hip adduction [Results] The COP deviation significantly decreased and the SA and L1 spinal muscles were significantly increased during push-ups with hip adduction when compared with push-ups without hip adduction. [Conclusion] We thought that the push-up exercise with hip adduction might help to selectively strengthen the SA.
