Resting Heart Rate
General Information
Measure Name: Resting Heart Rate
Measure Type: Single Item
Construct: Cardiorespiratory Fitness
Primary Content Area: Obesity
Secondary Content Area: Cardiovascular
Brief Description: Heart rate when at rest measured in beats per minute (bpm)

Cardiorespiratory fitness (CRF) varies significantly between individuals and may modify responses to obesity treatment either directly or via compliance with exercise recommendations (1). CRF is also significantly correlated with mortality and comorbidity risk, independent of body fatness (2). Though the gold standard for CRF is an ergometric VO2max test, an approximation can be made from resting heart rate or an alternative submaximal fitness test. Resting heart rate is easy and inexpensive to perform and has been reported to explain about 20% of the variance in CRF (3) using multiple different equations and calculations. The 3-minute step test has been reported to explain 50% to 90% of the variance in fitness by treadmill testing but may not be practical for larger studies or patient populations.
This step test could provide a reasonable alternaive under some circumstances (4,5). There is also a simpler version using a corridor walk for those who are unable to perform the step test because of orthopedic or fitness issues (6).
