Whole-body vibration (WBV) has emerged as an exercise modality that is safe for most adults with and without clinical conditions. The aims of this research study were to investigate the effects of WBV on vertical acceleration transmission during WBV and counter-movement jump height after WBV in typically developing children ages 6-11 years old. Seventeen subjects were recruited (10M/7F) for our study. We used a side-alternating Galileo WBV and presented a total of six conditions with the combination of three vibration frequencies (20, 25, and 30 Hz) and two vibration amplitudes (1 and 2 mm). Subjects stood for one minute on the platform under each condition. We used reflective markers to register the body motion and calculate the transmission of vertical acceleration during WBV. We used a force plate to collect ground reaction force during vertical jump after WBV and calculated jump height. Results showed that vertical acceleration significantly decreased from the ankle to the head. While vertical acceleration and its transmission ratio (with respect to the platform acceleration) increased with frequency and amplitude at the ankle, body segments superior to the ankle and knee were less affected by the vibration conditions. Counter-movement jump height maintained its value after all vibration conditions. It was concluded that WBV is a safe intervention paradigm for children as little acceleration is transmitted to the head, and a single bout of WBV may not be adequate to improve jumping performance in children.
