Physiological Demands of Common Occupational Tasks among Australian Police Officers: A Descriptive Analysis

Abstract

ObjectivesThe aim of this study was to investigate the physiological demands placed on Australian police officers carrying out common operational tasks.MethodsForty participants (n = 40) from an Australian police force (mean age = 33.58 ± 7.78 years, mean height = 177.70 ± 7.28 cm, mean weight = 85.68 ± 14.52 kg, mean years of service: 6.74 ± 6.29 years) were recruited through preidentified local area commands. Spanning nine police stations from the same Australian state, volunteers wore monitoring devices to collect physiological measures (heart rate, respiratory rate, and skin temperature) throughout the course of four consecutive shifts (two day shifts and two night shifts). Descriptive data were recorded and analyzed by task and changes in physiological measures.ResultsOf the 345 duty calls attended by participants, the four most commonly reported tasks were as follows: ‘check bona fides’ (n = 76; 22%), ‘driving urgently’ (n = 45; 13%), ‘attending a domestic incident’ (n = 37; 10%), and ‘attending a concern for welfare’ (n = 30; 8%). Mean percentages of maximum heart rates (%HRmax) were considered of very light exercise intensity and ranged from 47.11 (± 7.18) to 50.15 (± 9.35) % for checking bona fides through to driving urgently respectively. Fifteen percent of tasks attended had officers exceed 100 %HRmax (near maximal to maximal exercise intensity). Mean skin temperatures varied little (36.02–36.27°C) between tasks, while mean respiratory rates were lowest when attending a domestic incident and highest when driving urgently (22.56 ± 3.83 and 24.72 ± 6.12 breaths/min, respectively).ConclusionPolice officers experienced numerous physiological challenges ranging from an intensity of very light exercise through to near maximal and maximal exercise throughout their working day with occasions where their heart rates exceeded 100 %HRmax. These findings highlight the physiological stress associated with common occupational policing tasks, highlighting the importance of cardiovascular health in police officers and the need for cardiovascular monitoring and conditioning.
