Plain English Summary
Background and study aims
Physical activity (exercise) isnt just good for a child's health. Research has shown that physical education (PE) and physical activity can also improve academic performance. However, to date, there have been few studies looking into the effects of physical activity on the cognitive functioning (for example thinking, remembering, judging, and problem-solving) in children. Furthermore, the effects of prolonged sitting on the cognitive functioning of children has never been properly investigated, or indeed how physical activity (or prolonged sitting) affects childrens cardiometabolic health (i.e. their risk of developing heart disease or diabetes). Here, we are going to look into how feasible it is to set up a study to measure the effect of physical activity on the cognitive functioning of children when at school.
Who can participate?
Dutch speaking, healthy children between the ages of 10 and 13.
What does the study involve?
All participating children eat the same breakfast in the morning. They are then randomly allocated into one of three groups. Those in group A sit for a prolonged period in their classroom at school (all morning). Those in group B also sit in their classroom, but with an active break (where the children do a physical activity) halfway through the morning. Those in group C start the day with a physical activity, then sit down in their classroom with an active break halfway through the morning. Blood samples are taken from all the children just before they eat their breakfast and then at the end of the morning. They all take part in cognitive functioning tests at various times throughout the morning.
What are the possible benefits and risks of participating?
There is very little risk to taking part in this study. Blood samples are collected using a fingerprick method, a commonly used technique with few risks.
Where is the study run from?
Department of Public and Occupational Health, VU University Medical Centre, Amsterdam (Netherlands)
When is the study starting and how long is it expected to run for?
June 2013 to June 2014

Acronym
Study hypothesis
We hypothesized that both one as well as two bouts of moderate-intensity physical activity would enhance childrens selective attention, with larger effects for repeated bouts, when compared to sitting the whole morning.
