Abstract
The main objective of this study was to determine the optimal vibrating platform frequency and amplitude to stimulate increases in EMG muscle activity in the pectoralis major (PM), latissimus dorsi (LD), triceps brachii (TB), and bicep brachii (BB) during pushups. Fifteen subjects performed pushups with no vibration (NV), or random frequency (25, 35, 45 Hz) and amplitude (2 or 4 mm) combinations. Ratings of perceived exertion (RPE) and heart rate (HR) were collected following each condition. RPE data did not consistently demonstrate that vibration was significantly different from NV, and HR did not vary between conditions. The only statistically significant (p<0.05) increase in EMGRMS muscle activity over NV was demonstrated at the 45Hz, 4mm condition in the TB (4.37 ▒ 1.48 %MVE), and BB (7.64 ▒ 2.5%MVE). No other vibration conditions had an effect on PM, LD, TB, or BB muscle activty.
