Fig. 1From: The importance of cardiorespiratory fitness and sleep duration in early CVD prevention: BMI, resting heart rate and questions about sleep patterns are suggested in risk assessment of young adults, 18–25 yearsa. Illustration of the correlation between cardiorespiratory fitness measured as estimated maximal oxygen uptake, VO2 max and resting heart rate (HR), (r = − 0.31, P < 0.01). b. Illustration of the correlation between insulin resistance measured as homeostasis model assessment of insulin resistance (HOMA-IR) and body mass index (BMI), (r = 0.48, P < 0.01).Back to article page
