Spessato, Barbara Coiro; Gabbard, Carl; Valentini, Nadia C. – Journal of Teaching in Physical Education, 2013
Our goal was to investigate the role of body mass index (BMI) and motor competence (MC) in children's physical activity (PA) levels during physical education (PE) classes. We assessed PA levels of 5-to-10-year old children ("n" = 264) with pedometers in four PE classes. MC was assessed using the TGMD-2 and BMI values were classified…
