Abstract

Objective: The aim of this study is to understand the effect of strength training on muscle group activation.
Methods: Experiments were conducted with 20 track and field athletes. Muscle group activation data were collected by means of surface electromyography (EMG) equipment. Strength training was performed on a vibration table with the movement of half-squat and rise, and the frequency was controlled at 0 Hz, 30 Hz, 40 Hz, and 50 Hz. The EMG root-mean-square (EMGrms) (%MVC) of muscle groups at different frequencies were
compared.

Results: In the thigh muscle group, the EMGrms (%MVC) increased with the increase of vibration frequency; compared with 0 Hz, the EMGrms (%MVC) of the thigh muscle group increased significantly at the frequency of 50 Hz (p < 0.05). In the calf muscle group, the EMGrms (%MVC) increased with the increase of the vibration frequency; the EMGrms (%MVC) of the thigh muscle group under a frequency of 50 Hz was significantly different from that under 0 Hz.

Conclusion: Vibration strength training has a significant effect on the activation level of muscle groups and can be applied in practice.
