摘要：The addition of mechanical vibration to resistance training (RT) has been shown to have a positive influence on strength gains and muscle power. The purpose of this study was to determine the influence of local vibration on muscle hypertrophy. The sample included 20 untrained males who were randomly placed into 2 groups. The Vibration Group (VG) trained with the local application of vibration during RT. The Non-Vibration Group (NVG) trained without the application of vibration. Both groups performed resistance training (RT) for 12 wks, 3 times•wk~(-1) . The training protocol was: 4 sets of 8 to 10 repetition maximums of unilateral elbow flexion on a Scott-type bench with 120 sec rest between sets. Parameters of vibration: frequency of 30 Hz and amplitude of 6 mm. Although both groups exhibited significant increases in cross-sectional area from the distal and middle parts of the arm (NVG = 21.04 ± 6.88% and 19.03 ± 8.49%; respectively) at the end of the RT program (VG = 20.90 ± 4.74% and 19.16 ± 10.67%; respectively), the cross-sectional area of the distal arm was higher in the NVG versus the VG (17.41 ± 4.64%; P<0.05). Therefore, the findings indicate that application of local vibration does not need to be included in the RT program of untrained individuals.
