Physiological profile of professional fire fighters

Area of Science:

• Occupational Health
• Sports Science
• Human Physiology

Background:

• Firefighting is a physically demanding profession requiring high levels of physical capacity.
• Assessing the physical characteristics of firefighters is crucial for understanding occupational demands and potential health risks.
• Age-related changes in physical function can impact job performance and safety.

Purpose of the Study:

• To evaluate the physical characteristics, functional capacities, and body composition of professional firefighters.
• To determine the relationship between age and various physiological and performance metrics in this cohort.
• To establish baseline data for comparison with general population norms.

Main Methods:

• Cross-sectional study involving 45 professional firefighters aged 23-49 years.
• Assessment of maximum oxygen uptake (VO2 max) and recovery oxygen uptake.
• Measurement of arm and leg strength, hand grip strength, and body composition (percent body fat).

Main Results:

• A negative linear relationship was observed between age and VO2 max, recovery oxygen uptake, and arm/leg strength.
• Percent body fat increased with age, ranging from 18% to 21%.
• Hand grip strength remained relatively constant across all age groups, showing no significant decline.

Conclusions:

• Professional firefighters exhibit age-related declines in key physical capacities and an increase in body fat.
• While grip strength remained stable, other functional measures suggest a need for age-appropriate fitness maintenance.
• Implementing targeted training programs could help firefighters develop and sustain higher levels of personal fitness, potentially improving occupational performance and health outcomes.
