Article Synopsis
- The study aimed to compare the effects of video game breaks versus intermittent exercise breaks on math performance in preadolescent children aged 7-11.
- A total of 39 children participated in four different conditions involving either low, moderate, or high-intensity exercise breaks or sedentary video game breaks during an 8-hour sitting period.
- Results showed no significant differences in math scores based on the type of break taken, but overall performance decreased by the end of the day, indicating that time of day affects math performance, which could have implications for classroom activities.
Background: Short-term and long-term exposure to prolonged sitting is associated with excess food intake and weight gain in children. Interrupting prolonged sitting with low-intensity activity has been shown to not alter hunger, satiety, or food consumption in children, however it is unclear whether interrupting sitting with high-intensity activity will alter appetite regulation in children.
Purpose: The purpose of this study was to examine the acute effects of interrupting prolonged sitting with intermittent activity performed at varying intensities on hunger, satiety, prospective food consumption (PFC), and food intake in preadolescent children.
Background: The purpose of this study was to examine the acute effects of intermittent physical activity (2-min 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: A total of 39 children (healthy weight, n = 26; overweight/obese, n = 13) completed 4 experimental conditions in random order, which consisted of 8 hours of sitting interrupted with 20 two-minute low--, moderate-, or high-intensity activity breaks or 20 two-minute screen-time breaks. Mood was assessed using the Feeling Scale immediately following each break.
Article Synopsis
- The study aimed to understand how different types of short, intense physical activities versus sitting for a long time affect children's overall physical activity levels.
- Conducted with 33 children aged 7-11, the research involved several conditions where kids alternated between sitting and engaging in low-, moderate-, or high-intensity activity breaks, as well as breaks playing sedentary computer games.
- Results showed that only high-intensity activity significantly increased total daily energy expenditure, while low- and moderate-intensity activities, as well as prolonged sitting, had little to no effect on children's spontaneous physical activity outside of the lab, suggesting activity breaks might not lead to increased overall movement.
