유산소 운동시 운동수행 방법에 따른 평균심박수와 에너지소비량 비교 = Comparison on Energy Expenditure and Mean Heart Rate according to Exercise Performance Methods during Aerobic Exercise

다국어 초록 (Multilingual Abstract)

The purpose of this study was to compare on energy expenditure and mean heart rate according to the exercise ways of self paced exercise, self perceived THR exercise and personal trainer helping THR exercise during bicycle aerobic exercise for 30 minutes. 10 male college students(23±1.0 year. 174±1.4 cm, 70±5.2 kg, 17.7±3.36 %BF) participated voluntarily on this experiment. They were to engage in a 30-min bout of bicycle aerobic exercise(5 min: warm-up, 20 min: main exercise, 5 min: cool down). All participants measured their heart rate reserved(HRR). And then figured target heart rate(THR) with their respective % 70 HRmax respectively. They performed with 3 exercise ways. There were the self paced exercise(SPE), the self perceived THR exercise(SPTE), and the personal trainer helping THR exercise(PTTE) methods in the same amount of time, repeatedly. Subjects were measured energy expenditure(EE) and mean heart rate(mHR) at the point of warm-up, main exercise, and cool down. We analyzed it using oneway repeated measures ANOVA with SPSS/PC ver. 24. Statistical significance was defined as p<.05. In the main exercise section, EE and mHR in PTTE method was markedly higher than SPE and SPTE. It showed significant difference(p<.001).
Meanwhile, in the whole 30-min exercise, mHR in PTTE way was the highest. It demonstrated a statistically noticeable difference(p<.001). On the basis of these results, we have to be assisted with personal trainer, when aerobic exercising. These findings indicate that the exercise using the optimal THR under the personal trainer is expected to be more efficient than SPEM and SPTE.
