Abstract: Sport events and fitness activity are the result of interaction between human action and the environment or sports equipment. The various tissues and structures in humans as well as different equipment and apparatus have natural and imposed frequencies under the effect of external forces. Athletes can change a wobbling mass to a stiffness mass by increasing their muscular stress and then modifying their movement frequency to adapt to the equipment’s vibration frequency, and so achieve resonance effects. Thus it is necessary to measure the natural frequency of the human body and sports apparatus, as well as to obtain resonance between them through an athlete’s skill. We describe the application of vibration in sports training. Since the mechanism of the body’s reaction to vibration is not yet fully understood, the role of vibration in sports training needs to be studied in greater depth.
