OBJECTIVE
To examine associations among objectively measured physical activity (PA), body mass index (BMI), waist circumference (WC), and cardiorespiratory fitness (CRF) in firefighters.
METHODS
Career firefighters (n = 29; male = 100%) wore accelerometers to assess PA. BMI and WC classified obesity. Each participant completed a stage-graded exercise test to determine maximal oxygen uptake ((Equation is included in full-text article.)).
RESULTS
Two linear regression models were used to investigate whether PA intensities, step count, BMI, or WC were predictive of "true" (Equation is included in full-text article.). Vigorous physical activity (VPA) was predictive of "true" (Equation is included in full-text article.)(F[1,27] = 7.89, R = 0.23, P < 0.01). Additionally, when BMI and WC were added, only WC was predictive of "true" (Equation is included in full-text article.)(F[1,27] = 11.76, R = 0.30, P < 0.01).
CONCLUSION
Fire departments should be cognizent of ways to increase PA levels, decrease excess weight gain, and maintain CRF to adequately perform job-specific tasks.
目的
探讨消防员的体力活动（PA）、身体质量指数（BMI）、腰围（WC）和心肺适能（CRF）的客观测量值之间的关联。
方法
职业消防员（n=29；男性=100%）佩戴加速度计来评估 PA。BMI 和 WC 用于分类肥胖。每位参与者都要完成分级递增运动测试，以确定最大摄氧量（（方程式包含在全文中））。
结果
使用两个线性回归模型来研究 PA 强度、步数、BMI 或 WC 是否可预测“真实”（方程式包含在全文中）。剧烈体力活动（VPA）可预测“真实”（方程式包含在全文中）（F[1,27]=7.89，R=0.23，P<0.01）。此外，当 BMI 和 WC 被加入模型时，只有 WC 可预测“真实”（方程式包含在全文中）（F[1,27]=11.76，R=0.30，P<0.01）。
结论
消防部门应该意识到增加 PA 水平、减少体重过度增加和维持 CRF 以充分执行特定工作任务的方法。
