Physiological demands and physical performance determinants of a new firefighting simulation test

Area of Science:

• Sports Science
• Occupational Physiology
• Firefighter Performance Analysis

Background:

• Firefighting demands significant physical exertion, necessitating robust physiological capabilities.
• Assessing firefighter fitness is crucial for operational safety and effectiveness.
• The development of standardized tests is essential for evaluating job-specific physical demands.

Purpose of the Study:

• To evaluate the physiological responses of firefighters during a firefighting simulation test (FST).
• To identify the relationship between physical fitness parameters and performance in the FST.
• To establish minimum physical requirements for firefighter recruitment and safety.

Main Methods:

• 37 firefighters (21 professionals, 16 volunteers) underwent physical fitness assessments (aerobic, strength, endurance, anaerobic).
• Participants completed the FST, with measurements including performance, respiratory gas exchange, heart rate (HR), perceived exertion, and blood lactate.
• LASSO regression was used to predict FST performance based on fitness parameters.

Main Results:

• The FST significantly challenged both aerobic and anaerobic energy systems in male and female firefighters.
• While males were faster in FST tasks, final scores, HR, and perceived exertion did not differ significantly between sexes.
• Aerobic capacity and maximal strength were key predictors of FST performance.

Conclusions:

• The FST is a valid and demanding test for assessing firefighter physiological capacity.
• Cardiorespiratory fitness and muscular strength are critical determinants of success in firefighting roles.
• Minimum physical standards, informed by tests like the FST, are vital for firefighter and public safety.
