탈진 운동 후 회복 중 선호 및 비선호 음악 청취가 회복기 심박수, 혈중 젖산 및 타액 코티졸 농도에 미치는 영향

Abstract

Purpose: After exercise, the effects of music listening during recovery have been previously evaluated. However, the effects of preferred and non-preferred music listenign during recovery are not yet clear. Therefore , the purpose of this study is to investigate the effect of preferred and non-preferred music listening on recovery heart rate, blood lactate and saliva cortisol during recovery after exhaustion exercise. Method: The subjects of the study were 7 undergraduate students who were each exposed to three conditions at the interval of one week. Three conditions were contrlo treatment (CT), preferred music treatmen t (PMT), non-preferred music treatment (NMT). Recovery heart rate, lactate, and saliva cortisol were measured to identify the physiological response by music listening after maximum exercise. Using the SPSS 21.0 program, the data was analyzed by using repeatedly measured ANOVA. The igsnificant level of hypothesis verification was set up as α=.05. Results: The results of this study showed the following: 1) The recovery heart rate showed a significant difference in interaction effect (p<.05). As a result of the post-hoc analysis, the PMT was statisctally significantly lower than that of CT at 5 minutes of the recovery period (p<.05). 2) Lactate showed a significant difference in interaction effect (p<.05). As a result of the post-hoc analysis, the PMT and NMT were statistically significantly lower than that of CT at 10 minutes of the recovery period p(<.05). Also, PMT was statistically significantly lower than that of CT at 20 minutes of the recovery period (p<.05). 3) Salivary cortisol did not show a significant difference (p>.05). Conclusion: In conclusion, as one of the ways to recover after exerciseli,s tening to preferred music affects the autonomic nervous system, and helps relieve muscle tensionto reduce heart rate, and remove lactic acid . Therefore, this study suggests that listening to preferred music during recovery has a positive effect. And it can be utilized as a part of the fatigue recovery method after exercise.
