Task: Answer Verification
Input (English): Question: Does an unstable support surface increase scapulothoracic stabilizing muscle activity during push up and push up plus exercises?
Answer: The unstable surface used in this study is not a sufficient condition to generate an increase in muscle activity in select scapulothoracic and glenohumeral muscles during push up exercise variations. Elevating the feet above the hands appeared to have a greater influence on shoulder stabilizing musculature amplitude than the addition of a Swiss ball.
Output (English): no
