Activity Breaks for Brain Health in Adolescents

Summary

The main aim for this study is to investigate to what extent physical activity of moderate or low intensity, relative to prolonged inactivity, may acutely alter neural activity-related prefrontal cortex oxygenated hemoglobin during a cognitive demanding task in 13- 15 year-old adolescents. The study is primarily focused on investigating these effects in ecologically valid conditions, i.e. activity patterns that closely resemble a typical day in school and using activity modes that are suitable in a school setting.

Interventions

BEHAVIORAL

Prolonged sitting (social breaks)

Participants are required to sit for 80 minutes doing schoolwork, with a toilet break in between. Every twenty minutes participants will have a short social break. Test day begins at 8:00 with pretest measures, followed by the intervention at about 9:00, which will end around 12:00, with subsequent posttest measures.

BEHAVIORAL

Prolonged sitting with step-up exercise break

Participants are required to sit for 80 minutes doing schoolwork, with a toilet break in between. Every twenty minutes participants will have a physical activity break, where they will perform a simple moderate-intensity step-up exercise for three minutes at a predetermined pace. Test day begins at 8:00 with pretest measures, followed by the intervention at about 9:30, which will end around 12:00, with subsequent posttest measures.

BEHAVIORAL

Prolonged sitting with simple resistance activity breaks

Participants are required to sit for 80 minutes doing schoolwork, with a toilet break in between. Every twenty minutes participants will have a physical activity break, where they will perform simple resistance activities following a video for about three minutes. Test day begins at 8:00 with pretest measures, followed by the intervention at about 9:30, which will end around 12:00, with subsequent posttest measures.
