The purpose of this study is to discuss the mechanism of vibration training in improving muscle strength from the perspective of sports biomechanics. 60 male rats of 3 months old are randomly divided into quiet control group, 25Hz training group, 35Hz training group, 45Hz training group. The biomechanical parameters of gastrocnemius are measured by AGIS-MS material testing machine of the SHIMADZU Corporation. The results show that: in 25Hz training group, the maximum load, the energy absorbed to maximum load, elastic modulus and maximum stress increase very significantly (P<0.01), while the strain to maximum load decrease significantly (P<0.05). In 35Hz training group, the biomechanical parameters of rat gastrocnemius are of no statistical significance (P>0.05). In 45Hz training group, the maximum load, the energy absorbed to maximum load, elastic modulus and maximum stress increase significantly (P<0.05), while the strain to maximum load indicates no significant change (P>0.05). It concludes that elastic elements in muscle mechanical model play the main role in vibration training.
