| Popis: | Ebing, J, Gast, U, Hauptmann, C, Felsenberg, D, and Belavý, DL. Hypertrophy and explosive-reactive functioning in sedentary men after 10 weeks of whole-body vibration. J Strength Cond Res 32(1): 27-36, 2018-The objective of this study was to determine the impact of vertical (Power-plate; POW) and side-alternating (Galileo; GAL) whole-body vibration exercise on muscle mass and lower-limb neuromuscular function. Forty-three sedentary male subjects (18-30 year) randomized into 3 groups underwent 2 upper-body exercise sessions per week for 10 weeks. Two groups of subjects underwent additional squat exercises on the GAL (N = 15) or POW (N = 14) devices. The third group was control. On magnetic resonance imaging, volume of the thigh muscles was measured. Countermovement jump, multiple one-leg hopping, drop jump, landing test, 15-m sprint, and grip strength were performed. Measurements were performed at baseline, and at 5 and 10 weeks. Significantly greater increases in vasti volume were seen in the GAL (+4.15%; p = 0.00076 vs. control) and POW (+4.81%; p = 0.0074 vs. control) groups than in the control group (-1.22%) at 10 weeks. The adductor magnus volume increased in the GAL (+2.24%; p = 0.00038 vs. baseline) and POW (+2.33%; p = 0.00038 vs. baseline) groups at 10 weeks, but this was not significantly different from the control (-0.67%; p = 0.54 vs. baseline). Hamstring volume decreased in GAL (-1.85%; p = 0.00038 vs. baseline) at 5 weeks with the reduction in the POW group at 5 weeks (-1.73%; p = 0.17 vs. baseline) not reaching significance. There were no significant differences between the POW and GAL groups (p ≥ 0.084) and no significant changes in neuromuscular performance. Twice weekly squat exercises with whole-body vibration, progressing from 3- to 5-minute time under tension, lead to thigh muscle hypertrophy but no improvements in explosive-reactive function. |
