Resting Heart Rate Predicts Fitness Level
The inverse relation between resting heart rate and maximal oxygen consumption is directly correlated with physical fitness and adiposity. Resting heart rate is a biomarker for fitness and, therefore, a predictor of cardiorespiratory health. An increase in resting heart rate has been linked to an increase in all-cause mortality from chronic diseases, such as type 2 diabetes and cancer. Resting heart rate can be used as a low-cost, noninvasive way to assess risk for cardiovascular disease and the effectiveness of interventions related to physical activity.
@bipin Mean resting heart rate while seated was 67 beats per minute, while supine was 64 beats per minute, and while sleeping was 57 beats per minute. An increase of one beat per minute in supine heart rate was associated with a decrease in fitness level of 0.23 mL/min per kg.
