ReviewImpact of short bouts of physical activity on attention-to-task in elementary school children.
The study's objective was to describe the measurement of on-task behavior and review the research on the effects of short physical activity breaks on attention-to-task in elementary school students, with a particular focus on a promising approach to improving on-task behavior with short bouts of physical activity in the classroom setting. ⋯ Attention-to-task is a variable that directly relates to concerns of classroom teachers. The limited available research has demonstrated moderate to good evidence that physical activity during the school day improves attention-to-task in elementary school students. Because of the positive effects of physical activity on attention-to-task, it is recommended that elementary school teachers consider implementing physical activity sessions throughout the school day in the form of recess and classroom-based physical activities.

Estimating the potential of taxes on sugar-sweetened beverages to reduce consumption and generate revenue.
Beverage taxes came into light with increasing concerns about obesity, particularly among youth. Sugar-sweetened beverages have become a target of anti-obesity initiatives with increasing evidence of their link to obesity. Our paper offers a method for estimating revenues from an excise tax on sugar-sweetened beverages that governments of various levels could direct towards obesity prevention. ⋯ A modest tax on sugar-sweetened beverages could both raise significant revenues and improve public health by reducing obesity. To the extent that at least some of the tax revenues get invested in obesity prevention programs, the public health benefits could be even more pronounced.

ReviewA review of chronic and acute physical activity participation on neuroelectric measures of brain health and cognition during childhood.
A growing body of research has detailed the beneficial relation of chronic participation in--and acute responses to--physical activity on aspects of cognition that underlie scholastic achievement. Here, we review the relevant neuroelectric findings on this beneficial relation in children, providing support for the influence of physical activity on specific cognitive processes that comprise academic performance. ⋯ Physical activity may influence brain health and cognition in children, leading to enhanced scholastic performance and greater overall effective functioning across the lifespan.
