Muscle activity is expressed as a percentage of a maximum voluntary contraction (%MVC). A * indicates a statistically significant difference (p < .05) between the exercises using a Swiss ball or bench as the support surface (PUHands = Push up with hands on bench/ball, PUFeet = push up with feet on ball/bench and PUPHands = push up plus exercise with hands on ball/bench). | ||||||||
