title: Physical activity in police beyond self-report.
abstract: OBJECTIVE
  Police officers have a higher risk for cardiovascular disease. Reductions in occupational physical activity may contribute to the risk, yet there have been few efforts to characterize the physical demands of police work beyond self-report.
  
  
  OBJECTIVE
  To compare measured physical activity between work and off-duty hours and assess the effects of stress on physical activity.
  
  
  METHODS
  Officers (n = 119) from six departments wore a pattern recognition monitor for 96 hours to measure total energy expenditure (kilocalorie per hour) (1k/cal = 4184 joules), activity intensity, and step count per hour.
  
  
  RESULTS
  Participants were more active on their off-duty days than at work; the effects of stress on physical activity seemed moderated by sex.
  
  
  CONCLUSIONS
  Police work is primarily a sedentary occupation, and officers tend to be more active on their off-duty days than during their work hours.
