title: Physical activity in physical education: teacher or technology effects.
abstract: This study assessed if wearing a heart rate monitor influenced student activity levels in elementary physical education. Data were analyzed for 4 students using an alternating treatment design to assess differential effects between accelerometer activity counts obtained from students when wearing the heart rate monitor and when they were not wearing the monitor. Results show that (a) there was no difference in activity counts between the 2 conditions, (b) boys had higher means than girls, and (c) the variance between more and less active boys was greater than the variance among the girls.
