Key result
Higher aerobic fitness in police officers was associated with higher heart rate variability (SDNN 42.80 vs 36.85 ms; P≤0.05) regardless of specific duties.
Why the study?
It was unknown whether the specific duties of a police officer or aerobic fitness influences blood pressure and cardiac autonomic modulation.
Does aerobic fitness or specific duty type influence blood pressure and cardiac autonomic modulation in police officers?

Absolute Event Rate: 42.8% vs 36.85%
p-value: p=≤0.05
Higher aerobic fitness is associated with better cardiac autonomic modulation and lower obesity indicators in police officers, independent of their specific duties.
Supports fitness promotion for autonomic health in officers; leaves open causality and intervention effects.
PURPOSE: This study assesses whether the specific duties of a police officer or aerobic fitness influences blood pressure (BP) and cardiac autonomic modulation. METHOD: 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). RESULTS: 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). CONCLUSION: 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.

Santos et al. (2021) conducted a cross-sectional in Cardiac autonomic modulation and blood pressure (n=161). Higher aerobic fitness vs. Lower aerobic fitness was evaluated on Heart rate variability (SDNN) (p=≤0.05). Higher aerobic fitness in police officers was associated with higher heart rate variability (SDNN 42.80 vs 36.85 ms; P≤0.05) regardless of specific duties.
