Effects Of Different Rhythm Music On Autonomic Function Of Resistance Motor

Objective:Music can regulate the psychology and physiology of athletes in dynamic aerobic exercise.However,few studies have focused on the effects of different music rhythms on cardiovascular responses before and after dynamic resistance exercise.Dynamic aerobic exercise and dynamic resistance exercise have different cardiovascular response and adaptation modes.The purpose of this study is to explore the effects of different music rhythms on the autonomic nervous function of College fitness enthusiasts before,during and after dynamic resistance exercise.Method:13 subjects completed three random resistance exercise with different musical rhythm interventions,including the use of fast-paced,slow-paced and non-musical methods.The experiment was divided into 5 stages,namely,10 minutes of rest before exercise,15 minutes of warm-up,resistance movement,30 minutes of walking recovery after exercise and 30 minutes of flat sleep recovery.Anti-resistance movement movements are barbell squatting,reclining leg lift,sitting leg flexion and flexing leg hard pull,weight of 60% of the individual 1RM,each action needs to complete 3 groups,each group 12 repetitions,group rest time is 90 seconds,action break time is 2 minutes.Using Firstbeat heart rate monitoring devices to record the entire R-R interstitial period of the subject's experiment and perform heart rate variability(HRV)analysis,indicators include time domain indicators(heart rate(HR),R-R inter-period difference mean square root(RMSSD)and frequency domain indicators(low band power HFms2),high band power(LFms2),LF/HF ratio).In addition,blood pressure data were collected at various stages of the experiment.Results:(1)HR,RMSSD,LFms2,HFms2,LF/HF,DBP,SBP baseline indicators were not significantly different(P>0.05).(2)The peak heart rate of fast-paced music groups during exercise was significantly higher than that of slow-paced music groups and non-music groups(P<0.05).(3)Warm-up stage,fast-paced music group heart rate,LF/HF value is significantly higher than slow-paced and no music group.(4)In the course of exercise,fast-paced music has the most obvious effect on the heart rate improvement of sitting leg flexion action.(5)In the post-exercise recovery phase,there was no significant difference between heart rate and LF(ms2)between different intervention regimens,and the fast-paced music groups HF(ms2)and LF/HF were significantly higher than the slow-paced and musicless groups(P<0.05)20 minutes after exercise.(6)There was no significant difference between different blood pressure schemes at each stage during the experiment.Conclusions:1.Using fast-paced music to warm up before exercise can enhance the excitability of the sensory nerve and help to improve the warm-up effect.2.In the case of fast-paced music,slow-paced music and no music,there was no significant difference in heart rate during resistance exercise,but the use of fast-paced music can make the peak heart rate reached during exercise higher.3.Music can change the heart rate variability in the recovery period after exercise,using slow-paced music to help anti-resistance movement after recovery,but in contrast to no music,the effect is not obvious.
