To determine the effect of leg dominance on trunk muscle activity during bridging exercises on the floor and a gym ball. Perturbation training including bridging exercises and unstable surfaces have been shown to increase trunk activity. Trunk muscle activity increases on the contralateral side to the stabilising leg during bridging, however, no studies exist on the effect of leg dominance on trunk muscle activity during bridging exercises. This study will investigate whether trunk muscle activity differs when stabilising on the dominant versus non-dominant leg.Purpose
