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.
