CAL = RATIO * C RATE ; where : RATIO – user coefficient – number of calories, consumed per 1 step with the movement rate of 60 steps per minute. It is entered by the user in the entry mode of the user settings. Range of values is from 5.00 to 25.00; C RATE – coefficient of movement rate. It is calculated automatically during walk depending on the movement rate by each 5 steps in compliance with the table: Table .1 Movement rate, steps/min C RATE – movement rate coefficient 0065 5 6675 8 7685 11 8695 15 96105 19 106115 23 116125 28 126135 32 136145 36 Over 145 38 For instance: STEPS S4 t=4sec Rate= (5 steps/4 seconds)*60 seconds=75 steps per minute, C RATE=8; User coefficient RATIO is selected in dependence on height, weight and male/female identification of human.
