Mean values (±SD) in min/day (A-above) and in %-of-wear-time (B-below) for the exercise group (Exerc) and the control group (Contr) for various accelerometer parameters.

A significant difference (p1 ϴ; and between End and either of the two pre-tests (marked at each pre-test) with a star (*) both for the exercise group and the control group. The control group performed only one pre-test. The effect size (ES) of the interaction effect comparing the exercise group versus the control group over time (Pre-1-to-End), measured with partial eta-squared, with significance level (p2-value), are presented below the End-tests´ average values.
