Stress and Immune Mediators In The Canadian Armed Forces: Association Between Basal Levels and Military Physical Performance
Bibliographic record
Abstract
Purpose: This study aimed to determine if an association exists between basal levels of stress and immune mediators and military physical performance among Canadian Armed Forces members (CAF). \nMethods: Blood samples from 219 CAF members (86 women and 133 men), were analysed for levels of cortisol, C-reactive protein (CRP), Adiponectin, INF-γ, TNF-α, IL-1β, IL-2, IL-6, IL-8 and IL-18. Grip strength, aerobic capacity and performance on six military physical performance tests (sandbag fortification, escape to cover, picking and digging, picket and wire carry, stretcher carry and vehicle extrication) were also assessed. A composite score for total performance was computed, based on rank scores from the six tasks. \nResults: The results from the linear regression analysis showed that higher CRP values were associated with lower total performance scores (slope -23.0,p≤0.05), a slower picking and digging time (slope 45.75,p≤0.05), lower aerobic capacity (slope -71.81,p≤0.05) and shorter plank time (slope -21.82,p≤0.05). A positive association between IL-2 values and grip strength was also observed (slope 20.83,p≤0.05). Adiponectin values were positively associated with plank time (slope 21.42,p≤0.05), but negatively associated with grip strength (slope -8.27,p≤0.05). \nConclusion: The results from this study suggest that high levels of immune mediators (like CRP) could be a marker of decreased military physical performance.

How this classification was reachedexpand
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.
