Is There An Optimal Whole-Body Vibration Exposure ‘Dosage’ For Performance Improvement?, R Hugh Morton, Darryl J. Cochrane
Is There An Optimal Whole-Body Vibration Exposure ‘Dosage’ For Performance Improvement?, R Hugh Morton, Darryl J. Cochrane
International Journal of Exercise Science
International Journal of Exercise Science 7(3) : 169-178, 2014. Whole-body vibration exposure has been shown to improve performance in vertical jumping and knee extensions. Some studies have addressed the question of dose optimality, but are inconclusive and inappropriately designed. Our purpose was to more thoroughly seek an optimum combination of duration, amplitude and frequency of exposure to side-alternating whole-body vibration. We used experimental designs constructed for response surface fitting and optimisation, using both blocked and unblocked second order central composite designs with 12 participants. Immediately after each exposure a discomfort index was recorded, then peak and average torque, peak and …
