Effects of Interrupting Sedentary Behavior on Metabolic and Cognitive Outcomes in Children
In Brief
A Phase 2 clinical trial evaluating Walking on a Treadmill and Sedendary Activities Only for Healthy Volunteer. Completed, enrolled 89 participants across 1 site.
Detailed Summary
Background: \- Some studies in adults have found that insulin and glucose blood levels are lower when a long period of sitting is broken up with walking, compared to sitting without breaks. This means that the body can better process sugars when there are walking breaks during the day. Researchers want to know if this is also true for children. Some studies have found that children s attention and memory might be better after exercise. Researchers want to know if short walking breaks have the same effects. Objectives: \- To understand if breaking up sitting with walking helps children s bodies better use sugars and improves children s concentration. Eligibility: \- Healthy children ages 7 to 11. Design: * Participants will be screened with a physical exam, medical history, exercise test, picture vocabulary test, and medical tests including blood tests and X-rays. * Participants will return for two 7-hour visits. In the month before the visits, they will wear a physical activity monitor for one week so researchers know how active they are. Once they will take the sitting only test and once the sitting breaks test. * During the sitting only test, participants will sit for 3 hours. * During the sitting breaks test, they will sit for 3 hours with 3-minute walking breaks every 30 minutes. * Both days, they will drink sugar water. Then the participants will have blood drawn from a needle that is kept in place, and they will wear a heart monitor. They will take attention and working memory tests on a computer and answer questions about how they feel. They will eat a meal at the end of the test day.
