Regular physical activity is associated with lower CHD and diabetes risk.7 Self-reported physical activity is inversely related with CRP concentrations.8,9Cardiorespiratory fitness (“fitness”), assessed with maximal exercise testing, is stronger than self-reported physical activity as a predictor of several health outcomes.7,10 We showed higher fitness correlates with lower CHD risk factors.11–13 Blair and associates observed lower cardiovascular mortality14 and type 2 diabetes15 rates with higher fitness, irrespective of obesity status. Data on fitness and health parameters are particularly sparse among women and minorities.7,10,12,13 In the present study, we describe the cross-sectional association between fitness and CRP in a tri-ethnic sample of healthy women.
