OBJECTIVE
High cardiorespiratory fitness (CRF) is associated with reduced markers of oxidative stress and cardiovascular disease (CVD) risk factors; however, this relationship has not been elucidated in firefighters. The purpose of this study was to examine differences in markers of CVD risk between firefighters who have either high or low levels of CRF.
METHODS
Forty-six firefighters participated in a maximal graded exercise test and a dual-energy x-ray absorptiometry scan and provided a fasted blood sample. V˙O 2max values were categorized based on American College of Sports Medicine guidelines to establish high- and low-fitness groups.
RESULTS
High fitness firefighters demonstrated significantly higher high-density lipoprotein cholesterol and lower markers of CVD risk: cholesterol, triglycerides, low-density lipoprotein cholesterol, insulin, homeostatic model assessment for insulin resistance, C-reactive protein, and advanced oxidation protein products concentrations.
CONCLUSION
Firefighters are encouraged to maintain high CRF to reduce risk of CVD.
目的
高心肺适能（CRF）与氧化应激标志物及心血管疾病（CVD）风险因素的降低相关；然而，这种关系在消防员中尚未得到阐明。本研究的目的是检查心肺适能水平高或低的消防员之间CVD风险标志物的差异。
方法
46名消防员参加了最大分级运动测试和双能X线吸收法扫描，并提供了空腹血样。根据美国运动医学学院的指南对最大摄氧量（V˙O 2max）值进行分类，以建立高适能组和低适能组。
结果
高适能消防员的高密度脂蛋白胆固醇显著更高，而CVD风险标志物更低：胆固醇、甘油三酯、低密度脂蛋白胆固醇、胰岛素、胰岛素抵抗的稳态模型评估、C反应蛋白和晚期氧化蛋白产物浓度。
结论
鼓励消防员保持较高的心肺适能以降低心血管疾病风险。
