서킷 트레이닝이 비만 아동의 뇌기능관련변인과 뇌파에 미치는 영향

Abstract

This study examined the effect of circuit training on brain fucntion-related factor and brain wave in obese children. Eleven children between 10~13years of age were randomly assigned to either circuit trainign(CT; n=5) or aerobic training(AT; n=5). Participants participated in circuit or aerobic training program 3 times a week for 6 weeks. Exercise intensity was set at 65~85% HRR for CT and 40~60% HRR for AT while caloric expenditure per training session were approximately 350 kcal in both groups. Body composition, cardiorespiratory fitness, blood analysis and resting brain wave were measure pre and post the 6 weeks intervention period. As a result, no significant differences in exercise time or caolric expenditure was found between groups. CT and AT were effective for height, body weight, fat free mass, serotonin and resting brain wave(theta wave, SMR/theta ratio). In conclusion, as well as aerobic training, circuit training ddi improve body composition, cardiorespiratory fitness and cognitive ability. The data suggests that circuit training is an effective exercise modality to reduce body fat in obese children who are bored participating in a prolonged monotonous exercise. In further study, it needs to determine the effect of various intensity, time and modality of exercises on BDNF and brain wave in obese children.
