The purpose of the present investigation was to determine RMR, work intensity and Ea of various physical activities of healthy senior high school students and adults in Nagasaki. RMR was computed from energy expenditure during exercise and recovery period: 1) 15 min-run, indoor circuit training, outdoor circuit training(13 activities), aerobic dancing and 13 activities for senior high school students, 2) stepping up and down on a bench, bicycle pedaling, sit-ups, chest stretch, squat thrust (Burpee test), push ups and seven activities for male and female adults. The expired air was collected in Douglas bags during exercise and recovery. Fractions of O_2 and CO_2 were analyzed with San-ei gas analyzer (1 E21). Heart rate (HR) was measured with ECG (NIHON KODEN RM-5). Mean RMR obtained was 8.0 for 15 min-run, 5.9 for indoor circuit training, 7.8 for outdoor circuit training and 5.9 for aerobic dancing for students. RMR for male adults was 7.1 (female: 7.0) for stepping up and down, 4.5 (female: 10.6) for bicycle pedaling. 16.6 (female: 16.3) squat thrust, and 5.1 (female : 4.5) for sit-ups. Mean heart rates (HR) for three female students, during aerobic dancing, were respectively 150.9, 154.5 and 189.8 beats per minute (bpm) and those of 15 min-run for three male students were 176.0, 185.4 and 186.8 bpm. Work intensity (% V_O2 max.) was 49-57 % V_O2 max. for 15 min-run, 38-45 % V_O2 max. for outdoor circuit training for male students. Mean Ea (kcal/kg/min) for students was 0.169 for 15 min-run, 0.147 for outdoor circuit training, 0.131 for indoor circuit training, 0.120 for aerobic dancing, and for adults 0.133 (female : 0.132) for stepping up and down, 0.092 (female : 0.191) for pedaling.
