Research conducted within the Victoria Police has previously highlighted problems in the area of employee health and fitness. Officers of law enforcement agencies require a level of health and fitness which will enable them to effectively carry out their daily duties. While much of a police officer's shift is sedentary in nature, intermittent bursts of physical activity require enhanced levels of physical fitness. Despite these physical requirements, after a brief probationary period, police officers are not normally required to undergo any form of medical or fitness assessment for the rest of their careers. A project was conducted within the Victorian Police Force entitled "Operation Physicop" over a twelve month period in a geographical area called 'Y' District (now 'F' and 'G'). The project aimed to measure the effectiveness of workplace health promotion within the Victoria Police Force by measuring changes in several health and fitness parameters as a result of interventions aimed at influencing health behaviour and the workplace environment in a positive way.
