This study assesses whether the specific duties of a police officer or aerobic fitness influences blood pressure (BP) and cardiac autonomic modulation.
Police officers (n = 161) were divided into administrative and operational (34.72 ± 5.98 vs. 33.95 ± 5.61 years old) groups, and subsequently divided into lower and higher aerobic fitness (35.49 ± 4.32 vs. 45.39 ± 13.10 mL·kg-1·min-1).
Higher SBP (125 ± 10 vs. 121 ± 10 mmHg; P = 0.02) and aerobic fitness (42.10 ± 5.57 vs. 38.51 ± 6.67 mL·kg-1·min-1; P < 0.01) were observed in the operational group. On the other hand, lower obesity indicators and higher heart rate variability (HRV) indices (SD1: 26.67 ± 14.19 vs. 20.98 ± 9.12; SD2: 54.04 ± 19.81 vs. 47.32 ± 18.85; RMSSD: 36.50 ± 18.78 vs. 29.90 ± 12.51; SDNN: 42.80 ± 16.05 vs. 36.85 ± 14.23 ms; pNN50: 17.32 ± 17.54 vs. 10.60 ± 10.77 %) were observed in the higher aerobic fitness group (P ≤ 0.05).
In summary, although the operational occupation had shown a negative influence on SBP, the HRV was not impaired in police officers. Additionally, aerobic fitness was related to differences in obesity indicators and HRV regardless of police duties. Our findings encourage the inclusion of BP and HRV measurements in routine health checks to screen for early hypertension and autonomic dysfunction.
本研究旨在评估警察的具体职责或有氧适能是否会影响血压（BP）和心脏自主调节。
将 161 名警察分为行政组（34.72±5.98 岁）和执勤组（33.95±5.61 岁），并进一步分为低有氧适能组（35.49±4.32ml·kg-1·min-1）和高有氧适能组（45.39±13.10ml·kg-1·min-1）。
执勤组收缩压（SBP）（125±10 与 121±10mmHg；P=0.02）和有氧适能更高（42.10±5.57 与 38.51±6.67ml·kg-1·min-1；P<0.01）。另一方面，低肥胖指标和更高的心率变异性（HRV）指数（SD1：26.67±14.19 与 20.98±9.12；SD2：54.04±19.81 与 47.32±18.85；RMSSD：36.50±18.78 与 29.90±12.51；SDNN：42.80±16.05 与 36.85±14.23ms；pNN50：17.32±17.54 与 10.60±10.77%）在高有氧适能组中更为常见（P≤0.05）。
总之，尽管执勤工作对 SBP 有负面影响，但警察的 HRV 并未受损。此外，无论警察职责如何，有氧适能都与肥胖指标和 HRV 的差异有关。我们的研究结果鼓励将 BP 和 HRV 测量纳入常规健康检查中，以筛查早期高血压和自主神经功能障碍。
