Data reduction was performed by Actlife software, version 6.11.7. For the validation data, at least 4 days of recording at least 8 hours per day (480 minutes / day) were considered 40. Of these 4 days, 2 days corresponded to the intervention and 2 without intervention (1 weekend day). The time of non-use was estimated based on periods of more than 20 consecutive minutes of zero. For data download, 15 seconds epochs were performed, based on recommendations to similar populations. The useful and non-time has been determined according to Troiano (2007). The cutoff points for determining the time spent on different intensities of PA followed the standards proposed by Evenson et al (2008). To determine time spent for physical activity /week in each of the intensities was necessary to perform a calculation to generate weighted averages in minutes / day, of PA intensities. Time spent in moderate-to-vigorous physical activity corresponded to the sum of moderate physical activity (AFM) and vigorous physical activity (AFV) values.
