Anthony.Walker@canberra.edu.au @walks547 Background Results Firefighting is physically demanding, with emergency responses conducted under difficult and hot operating conditions. It is well established that high levels of fitness are crucial to operational safety and effectiveness(1). Retirement ages in Australia are increasing and the effects of older firefighters on the operational response capabilities of services is unknown. Safely completing firefighting tasks requires a minimum VO2 max of 42 ml.kg-1.min-1(2). Australian fire services conduct physical abilities testing (PAT) during recruitment requiring 9.6 on a beep test (equivalent to 45 ml.kg-1.min-1). Work specific tasks are also undertaken but are not common between fire services. No Australian urban fire service tests fitness post-recruitment Research into the effects of ageing on the physical standard of Australian firefighters is lacking. Thus, this study aimed to understand changes in physical fitness, power and concurrent body composition as firefighters age.

Figure 2 (right)Predicted Aerobic Capacity by 10-year age groups. The dotted line represents VO2 of 42 ml.min-1.kg-1 required to safely complete firefighting operations. ^ Represents a significant decrease between age groups (p<0.001). * And ** represent a significant decrease (p<0.05). Methods • 73 male firefighters (age 38.9 ± 9.0 years, height 180.6 ± 6.6 cm, weight 84.2 ± 9.2 kg, service time 10.2 ± 8.8 years) underwent body composition and physical tests over two testing sessions within a 10 day period. • Testing consisted of • Session 1 - Body Composition – DEXA • Session 2 - Predicted aerobic capacity – YYRT1, and • - Work specific power testing • 77 kg Dummy Drag (60 m) • 50 m Hose Drag (25 mm charged hose) • Participants were grouped into 10 year age groups for analysis. A one-way ANOVA was conducted to compare test results according to the age groups. Figure 3:. Results of (A) Hose Drag and (B) Dummy Drag by 10- year age groups. The dotted lines represent the recruitment benchmark for ACT Fire & Rescue. * And ** represent significant increases in the time taken to complete the testing. Ageing is resulting in significant physical declines, possibly leading to reduced safety of older firefighters Conclusion • This study has shown that significant age related physical declines are occurring within Australian urban fire services. These declines are likely being exacerbated by a lack of cohesive health and fitness programming within the service and as a result have remained largely undetected. • With the mean age of firefighters increasing, it is important that firefighters can safely complete work tasks regardless of age. Therefore, we recommend that all Australian fire services implement evidence-based workplace health and fitness programs and monitoring to ensure that all firefighters are fit-for-duty at all ages. • Acknowledgements • Thanks to ACT Fire & Rescue for providing funding and operational firefighters and officers for this study.
