OBJECTIVE
To analyze the relationship between reaction time (RT), level of physical activity (PA), and anthropometric indicators in police officers in Special Operation Units.
METHODS
Twenty-two police officers (34.5 ± 9.1 years old) from Santa Catarina, Brazil, who were members of a Special Operation Coordination Unit. RT was measured by the Vienna Test System. Were obtained values of body mass index (BMI), body fat (BF), and waist-to-hip ratio. PA was investigated using the Physical Activity Evaluation Questionnaire.
RESULTS
Younger police officers (less than 34 years) and BF less than 15% presented better performance in RT when compared with older, and BF more than 15%, respectively. RT was negatively related to PA (rho = -0.48, P < 0.05), and positively related to BF (rho = 0.76, P < 0.01) and to BMI (rho = 0.46, P < 0.05).
CONCLUSIONS
Participants from the group with greater BF and insufficient PA reacted significantly slower than others.
目的
分析特警人员的反应时（RT）、身体活动（PA）水平与人体测量指标之间的关系。
方法
巴西圣卡塔琳娜州的 22 名警察（34.5±9.1 岁），他们是一个特别行动协调单位的成员。使用维也纳测试系统测量 RT。获得了身体质量指数（BMI）、体脂（BF）和腰臀比的数值。使用身体活动评估问卷调查 PA。
结果
与年龄较大（超过 34 岁）和 BF 超过 15%的警察相比，年轻（小于 34 岁）和 BF 小于 15%的警察在 RT 方面表现更好。RT 与 PA 呈负相关（rho = -0.48，P < 0.05），与 BF（rho = 0.76，P < 0.01）和 BMI（rho = 0.46，P < 0.05）呈正相关。
结论
BF 较大且 PA 不足的参与者反应明显较慢。
