Description
Summary:[Purpose] The aim of this study was to reveal the effect of using hand-grips and a labile surface during push-up exercise. [Subjects] We recruited 12 male subjects. [Methods] Push-up exercises were performed under four different conditions on a multi-function balance board: a stable surface with and without hand-grips, a labile surface with and without hand-grips. Muscle activities of the upper trapezius (UT), serratus anterior (SA), extensor carpi radialis (ECR), and flexor carpi ulnaris(FCU) muscles were recorded. [Results] Push-ups on the labile surface tended to increase greater activation of the SA, and significantly increased both UT and FCU activities compared with the same exercise on the stable surface regardless of hand-grip usage. Push-ups on the labile surface with hand-grips condition caused significantly increased in ECR activation compared to other conditions. [Conclusion] Usage of hand-grips is recommended when push-ups are performed on a labile surface to reduce muscular imbalance in the wrist.
