Regression Analysis of PAEE of Different Wearing Sites with SVM in the Low, Moderate, High Speed Exercise Categories

PAEE, physical activity-related energy expenditure.

All values are from linear regression analysis. Low represents <3.00 METs, 2-4 km/h. Moderate represents 3.00≤METs<6.00 METs, 5-7 km/h. High represents ≥6.00 METs, 8-10 km/h.

^*PAEE, represents energy expenditure (kg/kcal/min) at each speed, which calculated from the equation 'Oxygen consumption by exercise-Resting Metabolic Rate', and then transformed under the assumption '1 liter of oxygen produce 5 kcal'.

^†Signal Vector Magnitude (SVM) is the total value of vector of three axes (x, y, z cm/s²) measured using Fitmeter triaxial accelerometers.
