To assess the validity of the SenseWear Pro2 Armband in determining the energy costs of various physical activities in children.
Energy cost was measured using SenseWear Pro2 Armband and Oxycon Mobile in 20 healthy children aged 11-13 years.
Activities included resting, playing mobile games, stepping, bicycling, jumping, playing basketball, and walking/running on a treadmill at various speeds.
Statistical analysis was performed to compare energy costs from both measurement methods.
SenseWear Pro2 Armband significantly underestimated energy costs during most activities, particularly at higher intensities (P < 0.001).
The discrepancy ranged from -0.7 to -14.8 kJ x min(-1), indicating increased underestimation with higher activity levels.
A detailed table of MET values for physical activities in children was provided based on indirect calorimetry results.
