Study hypothesis
|
There is increasing concern that modern children lead very sedentary lives. An inactive lifestyle increases risks of obesity and metabolic disease, but may also have adverse effects on cognitive function. Two recent systematic reviews/meta-analyses have concluded that there is a need for a Randomised Controlled Trial (RCT) to test the hypothesis that exercise can affect cognition in children, and to determine dose-response relationships. The aim of this study is:
1. To test the hypothesis that chronic aerobic exercise has effects on attention and working memory in children
2. To pilot for a larger scale future RCT
