A 3-Minute Work Capacity Test Predicts Simulated Firefighting Performance.

Area of Science:

• Sports Science
• Occupational Health
• Physiology

Background:

• Firefighting demands high physical capacity.
• Predicting on-the-job performance is crucial for firefighter selection and training.
• Existing fitness tests may not fully capture the demands of firefighting tasks.

Purpose of the Study:

• To identify key fitness tests for predicting simulated firefighting performance.
• To develop a predictive model for firefighter task success.
• To assess the role of work capacity and maximal oxygen uptake in firefighting.

Main Methods:

• Thirty-six firefighters completed strength and work capacity tests.
• A simulated firefighting task course evaluated performance.
• Backward linear regression analyzed predictors including fitness tests, demographics, and oxygen uptake.

Main Results:

• The 3-minute pyramid test alone predicted 59% of performance variance.
• Including body mass increased predictive power to 71%.
• A model with the pyramid test, body mass, and maximal oxygen uptake (V̇o2 max) explained 81% of performance variation, with V̇o2 max being the primary predictor (69% variance).

Conclusions:

• Maximal oxygen uptake is the most significant factor in firefighter task performance.
• The 3-minute pyramid test is a time-efficient tool for assessing work capacity and predicting performance.
• Regular use of the pyramid test can guide firefighter training to improve essential physical abilities.
