摘要：
Engagement in regular exercise or physical activity (PA) is known to protect against cardiovascular disease. Evidence for this strong association comes from both epidemiologic studies in which individuals self-report their level of PA and randomized controlled trials in which individuals increase their level of PA to a pre-defined level for a specific duration. Misclassification biases associated with self-reported PA may underestimate the true reduction in cardiovascular disease (CVD) risk obtained through regular engagement in PA, particularly at high levels. Given the strong dose-response relationship observed between objectively measured PA and changes in CVD risk factors in randomized controlled trials, the estimated risk reduction associated with high levels of PA (> 2,000 kcal/wk) would be predicted to be larger than current estimates (30% risk reduction) derived from epidemiologic studies. Self-reported PA may underestimate the true risk reduction in CVD produced through engagement in high levels of PA, although definitive evidence is not available. © 2010 Springer Science+Business Media, LLC.
