This study investigated body composition and fitness test relationships from firefighters participating in a health and wellness program and categorized firefighters according to population norms relative to sex and age. Data from 270 firefighters (men = 258, women = 12) were analyzed, including body composition (body mass index [BMI], body fat percentage [BF%], waist circumference [WC], waist-to-hip ratio) and fitness (sit-and-reach, grip strength, leg press, crunches, push-ups, maximal aerobic capacity [V̇O]) tests. Mann-Whitney U-test analysis ( < 0.05) showed that male firefighters had a greater WC, WHR, grip strength and leg press. Female firefighters had a greater BF% and better sit-and-reach. Partial correlations controlling for sex indicated 22/24 correlations between body composition and fitness were significant ( = -0.143--0.640). ~52% of firefighters were overweight, and 25% were Obesity Class I-III. ~76% had an increased risk of cardiovascular disease (CVD) considering BMI and WC. ~22% were fatter than average-to-overfat considering BF%. Most firefighters (73-94%) were good-to-excellent in sit-and-reach, grip strength, and push-ups; average-to-well above average in crunches; average-to-above average in leg press; and had good-to-superior V̇O. Although most firefighters had better fitness compared to the general population, many had increased CVD risk. The data highlighted the need for comprehensive approaches to improving firefighter health and decreasing CVD risk.
本研究调查了参加健康和健康计划的消防员的身体成分和体能测试关系,并根据性别和年龄与人口正常值相对应的方式对消防员进行了分类。分析了 270 名消防员(男性=258,女性=12)的数据,包括身体成分(体重指数[BMI]、体脂肪百分比[BF%]、腰围[WC]、腰臀比)和体能(坐-伸手、握力、腿压机、仰卧起坐、俯卧撑、最大有氧能力[V̇O])测试。曼-惠特尼 U 检验分析(<0.05)表明,男性消防员的 WC、WHR、握力和腿压机更大。女性消防员的 BF%更高,坐-伸手距离更好。控制性别因素的偏相关分析表明,24 个体成分与体能之间的 22/24 个相关性具有统计学意义(=-0.143--0.640)。约 52%的消防员超重,25%为肥胖 I-III 级。考虑 BMI 和 WC,约 76%的消防员患心血管疾病(CVD)的风险增加。考虑 BF%,约 22%的消防员比平均至过胖。大多数消防员(73-94%)在坐-伸手、握力和俯卧撑方面表现良好至优秀;仰卧起坐方面平均至高于平均水平;腿压机方面平均至高于平均水平;V̇O 方面表现良好至优秀。尽管大多数消防员的体能比一般人群更好,但许多消防员的 CVD 风险增加。这些数据强调了需要采取综合方法来改善消防员的健康状况并降低 CVD 风险。
