운동습관이 줄넘기 운동 후 맥박수 회복 시간과 운동자각도에 미치는 영향

Jump rope is a the most common exercise for the healthy people. However, few studies have been shown how the exercise habits effect on heart rate and perceived exertion scale after jump rope with 100 repetitions. This study aimed to compare the time of heart rate recovery and perceived exertion scale after jump rope with a hundred repetitions between the excercise group and non-exercise group, and also to figure out responding metabolic equivalent of task same as the jump rope with a hundred repetitions. Thirty two healthy university students (male=16, female1=16) were participated in this study and were allocated two groups by excercise habits (exercise group=at least enjoy the sports activity 3 times per a week, over 30 minutes per a time). The pulse oximeter and stopwatch were used to measure time of heart rate recovery and the Borg s scale was used to measure perceived exertion scale after jump rope with a hundred repetitions. Metronome was used to apply the same rhythm of jump rope with a hundred repetitions. Independent t-test was used for statistical analysis (α=.05) There were significant differences in the time of heart rate recovery and perceived exertion scale between the excercise group and non-exercise group. The time of heart rate recovery of exercise group is shorter than that of non-exercise group (p=.001). The perceived exertion scale of exercise group is lower than that of non-exercise group (p=.001). These results suggest that the jump rope with a hundred repetitions could be perceived exertion scale as ‘light exercises’ or ‘fairly hard exercises in Borg s scale in healthy people. Hence, when applying jump rope in clinical setting, it should be considered to be physical exercise which is more than ‘fairly hard exercise
