Various exercise tests are used to check the physical ability of each individual person before determining a exercise prescription in health check centers. The physical ability of each person is highly dependent on aerobic capacity. Then, we have employed a graded exercise test using bicycle ergometers to know the maximal oxygen consumption. The result of the aerobic capacity was expressed as METS value. In addition to the exercise test, each person was required to have a exercise of which energy was 100 kcal.
　The users of the facilities for exercise of our health check center were required to record the exercise (heart rate during aerobic exercise, time for aerobic exercise, energy requirement, body weight etc.) in this center. We recommend the following formula to calculate a working calorie.
　1) walking exercise (kcal)= distance (km)×body weight (kg)×1/2
　2) running exercise (kcal)= distance (km)×body weight (kg)
　3) aerobic exercise (kcal)= HR (beats/min)×time (min)×constant
　　constant= METSmax×body weight (kg)×0.015/HR.
　　HRmax= -0.8×age+216
　The users who did not have medical check were required to conduct the step test, which was originally developed in our center, to estimate METSmaX.
　This exercise test system works well and users can calculate the working calorie.
