Effect of strength training with vibration on bilateral force and impulse difference
Journal Title: Antropomotoryka. Journal of Kinesiology and Exercise Sciences - Year 2011, Vol 21, Issue 55
Abstract
[b]Aim of the study.[/b] The purpose of the present research was to verify the chronic effects of vibration during bilateral strength training on the force and impulse difference among contralateral limbs obtained in the vertical jump.[b]Material and methods.[/b] Fifty-one untrained male volunteered to participate in this study. Volunteers were randomly distributed in 4 groups: the Isometric group (n = 13), the 8-Hz group (n = 13), the 26-Hz group (n = 13) and the Control group (n = 12). Volunteers were submitted to 4-week of isometric training (Isometric group), isometric training associated with the application of 8 Hz (8-Hz group) and 26 Hz (26-Hz group) frequency of vibration. This training was done three times a week and made up of 12 maximal voluntary contractions (MVCs) in a semi-squatting position. The Control group did not execute any kind of training and was instructed not to execute any kind of systematic physical activity during the period of the research.[b]Results.[/b] Only the group submitted to 8-Hz vibration frequency had a significant decrease in force (p = 0,005) and impulse (p = 0.017) difference among contralateral limbs. The 26-Hz frequency, unlike imagined, did not reduce de force (p = 0,261) and impulse (p = 0,925) difference among contralateral limbs.[b]Conclusions.[/b] In conclusion, exposure to 4-week isometric training, when applying vibrations with frequencies of 8 Hz in the direction of the resultant muscle forces’ vector addition, was able to significantly decrease the force and impulse difference between limbs. Conventional isometric training and exposure to vibration frequencies of 26 Hz did not produce the same effects.
