Abstract
Resting heart rate (RHR) has been widely recognized as a potential indicator of cardiovascular health. Aerobic fitness is an essential component of overall physical fitness and is inversely associated with cardiovascular disease risks. However, the relationship between RHR and aerobic fitness in young adults remains a subject of interest. Objective: To determine the correlation between resting heart rate and aerobic fitness in young adults. A cross-sectional study was conducted among 500 young adults aged 18-30 years. Participants' RHR was measured after a 10 min resting period using a digital heart rate monitor. Aerobic fitness was assessed using the maximal oxygen uptake (VO2 max) test on a treadmill. Correlation analysis was used to determine the relationship between RHR and VO2 max values. There was a significant inverse correlation between RHR and VO2 max (r = -0.65, p<0.001). Participants with a lower RHR demonstrated higher aerobic fitness levels. The regression analysis also indicated that for every 1 beat min‾1 increase in RHR, there was a decrease of 0.40 mL kg‾1 min‾1 in VO2 max. This study confirms an inverse relationship between resting heart rate and aerobic fitness in young adults. Lower RHR may be an indicator of better aerobic fitness, which can serve as a non-invasive marker for cardiovascular health in this population. Further studies are recommended to understand the underlying mechanisms and potential implications for interventions.
