Key result
Cardiorespiratory fitness and high-intensity activity correlate with resting heart rate variability in male firefighters.
Why the study?
The study aimed to measure the association between physical activity levels, cardiorespiratory fitness, and resting cardiac autonomic function in firefighters at the fire station.

Are physical activity levels and cardiorespiratory fitness associated with resting cardiac autonomic function in firefighters?
Higher cardiorespiratory fitness and high-intensity physical activity are associated with improved resting cardiac autonomic function in firefighters.
Marcel‐Millet et al. (2024) conducted a cross-sectional in Healthy (Firefighters) (n=98). Physical activity levels and cardiorespiratory fitness was evaluated on Cardiac autonomic function (heart rate variability indices) at rest. Cardiorespiratory fitness and high-intensity physical activity were significantly correlated with resting heart rate variability indices in male firefighters.
