Height and mass were assessed to determine body mass index (BMI). The 20m multistage shuttle\u2010fitness test (MSFT) was used as an estimate of aerobic fitness. Capillary blood sampling was used to determine: total cholesterol, triglycerides, high\u2010, and low\u2010density lipoprotein. These were combined with measures of systolic blood pressure as <jats:italic>z<\/jats:italic>\u2010scores and summed to create a CVD risk score.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Analysis of covariance, controlling for sexual maturation, indicated a significant main effect for BMI as a result of fitness category (<jats:italic>P<\/jats:italic>\u2009=\u20090.0001).
