abstract = {Background: This study aims to examine the relationship between resting vagal-related
heart rate variability (HRV) parameters
and heart rate (HR) with resting metabolic rate (RMR) and respiratory exchange ratio (RER) in young adults.
Methods: A total of 74 young adults (22 ± 2 years old, 51 women) were included in this cross-sectional
study. HRV was assessed
using a HR monitor, whereas RMR and RER were determined by indirect calorimetry.
Results: Linear regression analyses showed a positive association between HR and RER in women (standardized β = 0.384,
p = 0.008), while negative associations were observed between vagal-related
HRV parameters and RER in women (β ranged from
−0.262 to −0.254, all p ≤ 0.042). No significant association was found between the abovementioned physiological parameters in men.
Conclusion: Here, we show that HR is positively associated with RER in young women but not in men, while vagal-related
HRV
parameters are inversely related to RMR, therefore suggesting a potential sexual dimorphism between cardiac rhythm and its
relationship with markers of cardiometabolic health status.},
