Association Between Metabolic Syndrome and Physical Fitness in Firefighters in Cape Town, South Africa

Abstract

Objective To assess the relationship between metabolic syndrome (MetS) and physical fitness in firefighters. Methods Firefighters (n = 309) were systematically recruited to participate in this study. A questionnaire and physical measures were used to collect data on firefighters’ cardiometabolic health and physical fitness levels. Data were analyzed using binary and multinomial logistic regressions. Results The prevalence of MetS was 23.0%, which was most prevalent in station and platoon commanders. Multivariable analysis showed that age (P < 0.001), lean body mass (P < 0.001), absolute aerobic capacity (P < 0.001), and leg strength (P < 0.001) was significantly associated with MetS. In addition, relative aerobic capacity (P < 0.001), push-ups (P = 0.016), and sit-ups (P < 0.001) were inversely associated with MetS. Conclusions Firefighters with MetS had a higher absolute aerobic capacity and strength, and healthier fighters had a higher relative aerobic capacity, muscular endurance capacity, and flexibility.
