Effect of push-up variations performed with Swiss ball on muscle electromyographic amplitude in trained men: A cross-sectional study.

Purpose: To compare the use of three variations of push-ups: traditional (stable surface), performed with hands on the Swiss ball (Swiss ball-hands), and performed with feet on the Swiss ball (Swiss ball-feet) on surface electromyography activity (sEMG) in the agonist and stabilizer muscles.

Methods: Ten trained men (26 ± 5 years, 76.8 ± 8.
