Objective:
Despite the physical demands of their job, firefighters often experience declining health, a trend that has worsened with coronavirus infection. We investigated the correlation between physical activity (PA) and metabolic syndrome (MS) risk factors in male firefighters following COVID-19 recovery.
Subject And Methods:
Pre- and post-COVID-19 MS risk factors were analyzed in 31 male firefighters. Pearson correlation was used to determine the relationship between PA and MS risk factors following recovery.
Results:
Postrecovery PA showed a moderate negative correlation with low-density lipoprotein ( r = -0.39, P = 0.04). Statistically significant reductions were observed in weight, body mass index, cholesterol, and waist-hip ratio (all P < 0.05). In contrast, glucose, triglycerides, and low-density lipoprotein showed statistically nonsignificant increases.
Conclusions:
Clinicians should monitor cardiovascular risks in firefighters, as subtle changes postrecovery may indicate increased heart disease risk.

Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
