RF-274 Cardiorespiratory fitness of police recruits: Norm-referenced values and 14-year temporal trend.
Bibliographic record
Abstract
<h3>Introduction</h3> Many have highlighted the increased risk of cardiovascular diseases (CVD) among police officers. Because a low cardiorespiratory fitness (CRF) in young adulthood is associated with a higher risk of CVD incidence, the identification of police officers exhibiting low CRF upon entry in the profession could allow the implementation of targeted strategies for the primary prevention of CVD. Unfortunately, reference values for the CRF of Canadian police recruits are not yet available. <h3>Objectives</h3> This research aimed to provide reference standards for the CRF of police recruits in Québec (Canada) and to evaluate the trend in the CRF of recruits over a 14-year period. <h3>Methods</h3> This cross-sectional study was divided into two research phases. First, fifty-one police cadets performed both an indirect calorimetry assessment of their maximal oxygen consumption (&Vdot;O2max) and the Physical Abilities Test (PAT) used for the recruitment of police officers in the province of Québec. Using results from both tests, a model was developed to estimate &Vdot;O<sub>2</sub>max based on PAT results. The CRF of police recruits who completed the PAT from 2004 to 2017 was then retrospectively assessed using the previously developed model. <h3>Results</h3> Based on the analysis of 7234 PAT results, the average &Vdot;O<sub>2</sub>max was 53.33 ± 2.90 ml·kg<sup>-1</sup>·min<sup>-1</sup> for male recruits and 43.78 ± 2.89 ml·kg<sup>-1</sup>·min<sup>-1</sup> for female recruits. Furthermore, bivariate correlation analyses suggested small but significant increases in the &Vdot;O<sub>2</sub>max of both male (r<sub>s</sub> = .105, p < .001) and female recruits (r<sub>s</sub> = .125, p < .001) over the 14-year period studied. <h3>Conclusion</h3> Our results suggest that the CRF of police recruits in Québec is considerably higher than their North American peers. Furthermore, although clear conclusions cannot be drawn from our temporal trend analyses, our data suggest that the CRF of police officers from this population did not decline over the last decades as previously suggested by others.

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.
