Effect of Television Viewing and Exercise on Appetite, Satiety, and Food Intake in Children

Study Overview
=================
Brief Summary
-----------------
The purpose of this study was to describe the effect of 30 min TV viewing with or without simultaneous moderate exercise using a treadmill on subsequent subjective appetite, satiation, and food intake in normal weight 9 to 14 year old children. It is hypothesized that TV viewing during exercise immediately before mealtime affects food intake regulation through its effect on the control of appetite and satiation.
