Faculty Research and Creative Activity
To compare core muscle activity during resistance exercises performed on stable ground vs. the BOSU Balance Trainer. Methods: Twelve trained men performed the back squat, dead lift, overhead press, and curl lifts. The activity of the rectus abdominis, external oblique abdominis, transversus abdominis/internal oblique abdominis, and erector spinae muscles was assessed. Subjects performed each lift under three separate conditions including standing on stable ground with 50% of a 1-RM, standing on a BOSU Balance Trainer with 50% of a 1-RM, and standing on stable ground with 75% of a 1-RM. Results: Significant differences were noted between the stable 75% of …
