The Relationship between Vibration Combined with Weight-load Stimulation and fatigue on the Specialized Strength Training of Latin Dance

Abstract

The aim of this study was to investigate the relationship between four kinds of vibration combined with weight-load stimulation and the fatigue of the inner gastrocnemius muscle,an important muscle of Latin dance in the lower limbs,and to find an appropriate combination mode of vibration frequency and weight-load intensity.Taking 10 college students who have been involved in Latin dance for a long time as the research objects,they completed 10 half squat heel raises exercises for one minute in each group,a total of 3 groups,and the rest interval between each group was 3 minutes.Four kinds of vibration combined with weight-load stimulation were added respectively,and the interval between each stimulation was more than 48h,and the surface EMG fatigue analysis results of the three groups of exercise processes of each stimulation were collected. The data were calculated using the curve fitting straight line formula, and the JASA method was used to compare and analyze the data.In the combination of 45Hz 50Hz,451RM and 601RM,the medial gastrocnemius had better adaptability to the combination of” same loading intensity+vibration with lower frequency” and the combination of “same vibration frequency +load with lower intensity”, which resulted in weaker fatigue and more stable myoelectric discharge frequency,which Provides a “quantity” guide for Latin dancers to combine vibration with weight training.
