Affective Responses to Intermittent Physical Activity in Healthy Weight and Overweight/Obese Elementary School-Age Children

BACKGROUND:The purpose of this study was to examine the acute effects of intermittent physical activity (2-minute bouts of varying intensities) on psychological mood and enjoyment in elementary school-age children and to examine the effect of weight status on these psychological outcomes. METHODS:Thirty-nine children healthy weight (HW), n=26; overweight/obese (OW/OB), n=13] completed four experimental conditions in random order which consisted of 8 hours of sitting interrupted with 20, 2-minute low-, moderate- or high-intensity activity breaks or 20, 2-minute screen-time breaks. Mood was assessed using the Feeling Scale immediately following each break. Enjoyment was assessed using the Physical Activity Enjoyment Scale immediately following 10 and 20 breaks. RESULTS:Mood was significantly higher during the sedentary vs. active conditions (p<0.01). OW/OB children reported lower mood scores compared to HW children at the initiation of the low- (p<0.05), and high-intensity conditions (p<0.001), but experienced improvements in mood throughout the day in all three active conditions (p=0.02). Enjoyment was significantly higher after completing the active vs. sedentary conditions (p=0.02). CONCLUSIONS:These findings suggest both HW and OW/OB children felt better immediately after engaging in screen-time breaks, but subsequently rated the activity breaks as more enjoyable compared to screen-time breaks.; BACKGROUND:The purpose of this study was to examine the acute effects of intermittent physical activity (2-minute bouts of varying intensities) on psychological mood and enjoyment in elementary school-age children and to examine the effect of weight status on these psychological outcomes.
