This study examined sources of variability in habitual physical activity of children, and the minimum number of days required for estimating chil-dren’s habitual physical activity levels using pedometers. A total of 31 children wore two pedometers during five weekdays and four weekend days. A two random facet completely crossed design was conducted with two-way analysis of variances across weekdays, weekends, and weekdays and weekend days combined. Moderate/high generalizabili-ty coefficients were estimated across all days. Primary sources of vari-ability were variance components of the person and person by day in-teraction. Minimum numbers of days required for estimating habitual physical activity levels using a pedometer were five during weekdays. However, estimating habitual physical activity levels during weekends, and weekdays and weekend days combined was impractical.
