Swiss ball exercises employed in a prone position were as effective or more effective in generating core muscle activity compared to the traditional crunch and bent-knee sit-up. The roll-out and pike were the most effective exercises in activating the core muscles compared to all exercises. Lumbar paraspinal activity was relatively low for all exercises. The sitting march exercise generated the lowest core muscle activity compared to all exercises.
Swiss ball exercises provided a wide range of activation of the core musculature.
IMPLICATION Our findings can be used to help guide core stability training and rehabilitation, using a variety of Swiss ball and traditional abdominal exercises.
