Maximal Oxygen Uptake and Coronary Artery Calcium Scores in Firefighters.
Objective: This study investigates the association between maximal oxygen uptake (VO 2 max) and coronary artery calcium (CAC) scores in Indiana firefighters across different age groups.
Methods: Using cross-sectional data, multivariable linear regression was conducted to examine the relationship between VO 2 max and CAC, stratified by age (<45 and ≥45 years), with adjustments for cardiovascular risk factors.
Results: Higher VO 2 max was significantly associated with lower CAC scores in firefighters aged ≥45 years (β = -7.30; 95% CI: -11.41, -3.18; P < 0.001). No association was detected in firefighters under 45 years. Differences may reflect unique occupational physical demands and age specific cardiovascular risk profiles.
Conclusions: Higher aerobic fitness is linked to reduced subclinical atherosclerosis in older firefighters, underscoring the importance of maintaining fitness to mitigate cardiovascular risks in this high risk group.
