Patient Recruitment

"Break it up" Study

Do Periods of Activity Improve Metabolism and Attention in Children?

a group of children running and playing

Researchers at the National Institutes of Health (NIH) Clinical Center seek healthy children, 7-11 years old to participate in a study. This study wants to learn how breaking up periods of physical inactivity with short periods of activity improves children's metabolism and attention span. Our previous research has shown that brief, moderate activity does help with metabolism in children for a short time. More information is needed to see if multiple days of activity have a longer and lasting effect.

Your child may be eligible if he/she is:

  • 7-11 years old
  • In general good health

Study information:

  • One outpatient screening visit of about 5 hours.
  • 6 outpatient visits on consecutive days of about 3 hours each (Monday - Friday, early evening and Saturday morning).
  • Children will be performing activities such as sitting and walking.
  • Parents/guardians will be informed about possible procedures and must give consent for participation.
  • Compensation is provided.

Location: The NIH Clinical Center, America's research hospital, is conveniently located on the Metro Red Line (Medical Center stop) in Bethesda, Maryland. There is no charge for study-related tests or procedures. Compensation and travel assistance may be provided.
