Whole body vibration exercise is more-and-more popularly used in training athlete's strength and power. However, inadequate researches have been documented in the relationship between applied frequencies and their body resonance responses. Purpose: To investigate the response of athlete's body during different frequencies of vertical whole-body vibration. Methods: this study used the Motion Analysis System and Borg 10 points scale to collect and calculate the transmissibility of different parts of body and intensity of vibration by subject’s feel. Subjects included 55 athletes from weight-lifting, body building, Chinese Martial Arts, Wushu, Tai Chi, wrestling and Judo team. Results: we found that the knee and hip joint were used to damp the vibration and avoid the vibration to transmit to the upper body and head. There is a resonance of knee in 12 to 20Hz when subject kept the position that bent the knee and stood on the vibration platform. Therefore, subjects can't use the knee joint to damp the vibration. The vibration with 4mm amplitude and above 24Hz may be too strong for the subjects, below 12Hz was too weak to train. Concluded: The whole body vibration need to reduce the amplitude below 2mm and elevate the frequency above 20Hz to void the danger of resonance and to have training effect.
