The Effect Of Plyometric Training On Lower Body Explosive Power And Athletic Performance Of Youth Latin Dancers

In recent years,the dance technique of teenagers has improved a lot over the years,the lack of physical training is the major factors affecting the dance performance of youth Latin dancers on the competition.Explosive power play an vital role in Latin dance.In Latin dance competitions,explosive power affects the dance performance of dancers,the explosive power has a profound impact on the performance of action speed,the accuracy of music rhythm,the creativity of artistic effects,and the interpretation of inner emotions.so it is important to improve dancers’ explosive power.Therefore,The purpose of the present study was designed to examine the effect of plyometric training on lower body explosive power of the youth Latin dancers.This article is experimental research.26 Latin dancers from dance school in Beijing were volunteered to participate in this study.The plyometric training program was applied to the Latin dance class.Participants were tested CMJ by Smart Jump and dance performance by referees on pre-test.Participants were divided into either experimental group or control group according to the the result of explosive power test.Experimental group went through a 8-weeks plyometric training with dance technique training 3 times a week,90 minutes per day.Control group went through a 8-weeks traditional physical training with dance technique training 3 times a week,90 minutes per day.After 8 weeks of training,participants conducted the post-test,including CMJ test and dance performance test,the five indexes of dance technique were selected by experts and 3 national referees gave score to each participant by video of dance combination of participants.Finally,the test results of the CMJ score and five indexes of dance technique were analyzed statistically,A 2(Group)× 2(Test)factoral analysis of variance(ANOVA)with the repeated measures on the test and a follow test were conducted to examine the main and the interaction effect of the data.The findings were found:The results of the analysis revealed a significant main effect on the test and a significant Group x Test interaction effect.The experimental group of pre-test demonstrated significantly higher level of CMJ performance than pre-test(P<0.001).There is no significantly difference between experimental group and control group(P=0.158).However experimental group demonstrated higher level of CMJ performance than the control group on the post-test.explosive power of dance indicators: after training,5 indicators of foot movement,timing,rotation and spin,energy,Latin action have significant improvement(P<0.001).There was no interaction between the two groups,and the results of 5 indicators of the experimental group were higher than the control group.Conclusion: The researcher in the present study concluded that plyometric training is beneficial to improvement in explosive power of the lower limbs and dance performance of the youth Latin dancers.
