야외 아동용 콤보형 자가발전 운동기구의 에너지소비량에 대한 연구

Abstract

This study is to find momentum of children's outdoor combo exercise equipment by measuring energy consumption and exercise intensity according to the exercise stage of the equipment. This children's outdoor combo exercise equipment is designed to fit children's standard body type and it is qualitatively different from a common exercise equipment that can be easily seen at neighborhood parks or city parks for repetitive weight training. 20 elementary school students who are living in capital area are selected as subjects. For understanding characteristics of the subjects, physical examination such as height, weight and body fat percentage is preceded. And blood pressure, heart rate, lactate level and fatigue degree are measured. To test graded exercise intensity application of children's outdoor combo exercise equipment, exercise tolerance test is done by setting 3 standards; low, medium and high intensity. The heart rate, oxygen uptake and energy consumption of the 20 subjects are measured and estimated through using children's outdoor combo exercise equipment for 2 minutes at 50 rpm. The results of this study are listed below. First, if boy students used the developed children's outdoor combo exercise equipment, low,medium and high intensity are corresponds to about 42W, 46W, 50W exercise intensity of a common bike and energy consumption 4.6kcal, 4.9kcal, 5.2kcal per minute. Second, if girl students used the developed children's outdoor combo exercise equipment, low,medium and high intensity are corresponds to about 40W, 50W, 55W exercise intensity of a common bike and energy consumption 4.5kcal, 5.1kcal, 5.4kcal per minute. As for the results described above, the exercise using children's outdoor combo exercise equipment requires 4.5 ~ 5.4 kcal energy consumption per minute. Therefore, the developed children's outdoor combo exercise equipment can be used outdoors for effective and enjoyable aerobic exercise of children who are short of exercise.
