Energy Requirements And Predictive Factors For Success In The Candidate Physical Abilities Test (CPAT) For Firefighters
Bibliographic record
Abstract
The Candidate Physical Abilities Test (CPAT) was developed by the International Association of Fire Chiefs (IAFC) and the International Association of Fire Fighters (IAFF) as a bona fide occupational requirement for the screening of potential recruits into the profession of fire fighting. PURPOSE: To measure the physiological responses during completion of the 8 item circuit that has a criterion completion time of 10min 20s, and to determine those characteristics associated with success. METHODS: 34 men (81.8 ± 12.2 kg, VO2max 53.0±7.4 mL/kg/min) and 23 women (64.0 ± 10.4 kg, 51.2±6.6 mL/kg/min) participated in the CPAT study after familiarization in accordance with CPAT guidelines. A portable breath-by-breath gas collection system measured oxygen uptake (VO2) during tests. Subjects completed an incremental treadmill running test to determine VO2max and strength tests of upper and lower body. RESULTS: 31 men and 4 women completed the CPAT under the 10-min 20-s criterion time. All subjects were encouraged to complete the circuit regardless of time, but 2 men and 8 women stopped due to fatigue. The energy cost of completing the circuit was correlated with VO2 in L/min (r2=0.60) but not for VO2 in mL/kg/min (r2=0.13); indeed VO2 measured during the test varied from ~30 to 47 mL/kg/min in individuals who completed the circuit in similar times. Respiratory exchange ratio exceeded 1.0 in men but not women. Backward stepwise regression revealed that the completion time could be predicted by the single variable of absolute VO2max expressed without consideration of body mass with all other variables dropped from the model (r2=0.65). VO2max expressed relative to body mass (r2=0.13) and total body mass (overall r2=0.25, men r2=0.07, women r2=0.01) were poor predictors of performance time. Women had considerably longer times for victim drag (71.3±66.6 vs. 24.8±7.4 s) and the breach and pull (109.5±55.8 vs. 52.0±15.1 s) components of the circuit. CONCLUSIONS: These results demonstrate the heavy demands of the CPAT circuit and the success of individuals with high absolute VO2max, although body size alone was not predictive of performance time.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
