Abstract

PURPOSE:: Cardiovascular disease (CVD) accounts for 44% of on-duty deaths among U.S. firefighters with a markedly higher event risk during strenuous duties compared to non-emergencies. Sedentary persons are most susceptible to such CVD "event-triggering" due to irregular bouts of vigorous physical activity (PA). Conversely, regular PA and increased levels of cardio-respiratory fitness (CRF) protect against CVD triggering. Therefore, the present study evaluates PA measures in structural firefighters and their relationship to CRF and CVD risk factors. METHODS:: Cross-sectional cohort study of 527 Midwestern career firefighters. PA frequency, duration and intensity measures from a questionnaire along with total weekly aerobic exercise were analyzed. CRF was measured by maximal exercise tolerance testing. CVD risk parameters included body composition, blood pressure and metabolic profiles. Group differences were compared using general linear models. RESULTS:: Measures of increasing frequency, duration, intensity of PA and total weekly exercise (minutes) were significantly associated with higher CRF (p
