In this study, the Power-I handheld vibration strength training apparatus is used to do the static and dynamic vibration tests on upper limb muscles of 26 healthy college students, and the Mega8 channel surface myoelectrical measurement instrument is adopted to collect myoelectrical data of related upper limb muscles for analysis. The study shows that the effects of vibration training device on the discharge of upper limb’s working muscles are significantly higher than those without applying vibration stimulation. The average discharge of upper limb muscles has very significant differences at the moment of applying vibration stimulation with respect to without applying it. The maximum discharge (except active muscles) has significant differences. And MPF values are significantly enhanced. Myoelectrical levels produced by vibration stimulation on the forearm muscles are significantly better than that of the upper arm muscles. The closer the muscles to the source of the vibration stimulation the more obvious they accept its effect.
