Boosting Executive Function With Real-class Exercise

The goal of this study is to examine the effects of acute pre-class physical exercise on executive function in real classroom settings. The main question it aims to answer is, "Does acute pre-class exercise enhance executive function compared to sedentary conditions?" Participants were students from primary school assigned by class to engage in one of several pre-class conditions: mentally passive sitting, mentally active sitting, 5-minute physical exercise, or 10-minute physical exercise. A cluster-randomized trial design was used to ensure ecological validity in authentic classroom environments. Cognitive tasks measuring inhibitory control were administered at baseline and pre-/post-class. The results indicate that pre-class exercise leads to greater improvements in inhibitory control than sedentary conditions, suggesting that integrating brief exercise sessions before lessons may be an effective strategy to optimize learning in educational contexts.

Smoothie Program for Achieving and Resilient Kids

The proposed study will examine whether eating yogurt every day can improve brain and gut health in children. Prior research suggests that yogurt may support cognitive functions like self-control, but more studies are needed to confirm this. The study will follow 60 children from Central Pennsylvania, ages 7 to 9, who will be randomly assigned to drink either fruit juice (control group) or yogurt smoothies once or twice a day for four weeks. Researchers will compare how different amounts of yogurt affect children's thinking skills (like memory and focus), brain activity, and gut bacteria. These changes will be measured through brain scans, computer-based thinking tasks, surveys, and stool samples. The study will also collect information about children's overall diet. The goal is to find out if yogurt can support healthy brain and gut development and to determine the right amount to include in a child's daily diet. Results will help guide future research on how nutrition supports children's health.
