The effects of a moderate physical activity program on heat tolerance in men
Bibliographic record
Abstract
Moderate intensity training induces health benefits, however its influence on heat tolerance is unclear. Twelve inactive males (mean +- SD) (age = 24 +- 6 yrs, BMI = 25.3 +- 3.2 kg/m2, V02peak = 40.2 +- 8.1 ml/kg/min) performed work-heat tolerance and V02peak tests pre and post a moderate training intervention. All subjects were initially below the guidelines for physical activity set forth by the US Surgeon General, Health Canada, and CSEP. Eight randomly assigned subjects underwent the 12-week program, participating in activities such as cycling, walking, and recreational sports. Subjects were instructed to train at 50% V02Reserve, and gradually increased energy expenditure to reach a mean of 2158 kcal/week, which is beyond the above mentioned recommendations. Four control subjects remained sedentary. In the training group, V02peak increased 19% (p < 0.01), and resting peripheral blood flow during heat stress increased (p < 0.01), indicating some initial thermoregulatory benefits. No significant differences were observed in esophageal temperature or sweat threshold. Health benefits associated with heat adaptations may require more vigorous exercise than recommended by current physical activity guidelines.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
