DB Bornstein, MW Beets, W Byun, K McIver - Journal of Science and …, 2011 - Elsevier
Objectives: This study synthesized the published estimates of daily moderate-to-vigorous
physical activity (MVPAd− 1) of preschooler-age children (3–5years). Design: Meta-analysis
of previously published studies reporting accelerometer-derived estimates of daily MVPA of
preschoolers. Methods: A comprehensive literature review was conducted to identify studies
published by March 2010 that reported daily minutes of accelerometer-derived MVPA in
preschool-age children (3–5years). Random effects point estimates and 95% confidence …
