Table 2. Mean and standard deviation of different PAs detection (time duration, min), specified-types of EE (kcal/min), and a 12 h total EE (kcals) measured with Fibion devices (FT and FP), compared to criterion 1 (direct observation) and criterion 2 (K4b2). (95% Confidence Interval).

Notes:

PA, physical activity; EE, energy expenditure; FT, Fibion worn on the thigh; FP, Fibion worn in the pocket; LSit, Long sitting (sitting periods over 30 min); LPA, light intensity PA (MET < 3, excluding sitting); MPA, moderate PA (3 < MET < 6); VPA, vigorous intensity PA (MET > 6); TD, total duration; 12 h EE, total EE during 12 h measurement protocol. ICC, Intra-class correlation coefficient; p-values refer to the Student’s t-test or the Wilcoxon signed-rank test.

p-Value = FT vs. FP.

The bold p-values indicating significant differences between the compared two groups.
