Nine Minutes to Better Grades: Simple Classroom Exercise Could Boost Thai Test Scores
A simple 9-minute movement break before tests may improve Thai students’ verbal comprehension and reduce anxiety-related brain patterns, new research suggests. The study, conducted with children aged 9-12, found that brief in-class high-intensity intervals improved performance on verbal tasks while decreasing neural signals linked to worry over mistakes.
Researchers from a leading university conducted six bodyweight exercises—such as high-knee marching, jumping jacks, air squats, and lunges—for 30 seconds on, 30 seconds off, in a typical classroom setting with no equipment. After the movement, students completed verbal comprehension tests while EEG monitored brain activity. Results showed faster, more accurate responses and lower error-related negativity, a brain marker associated with attentional lapses and anxiety during testing.
