PHYSICAL ACTIVITY LEVELS AND NUMBER AND DURATION OF UPPER RESPIRATORY INFECTIONS IN UNDERGRADUATE STUDENTS
Bibliographic record
Abstract
The common cold, also known as an upper respiratory tract infection (URTI) is the world's most prevalent illness. It has been suggested that URTIs are the world's most expensive illness caused by excessive numbers of lost workdays, physician visits, medications and complications; unfortunately researchers have not yet been successful in finding a cure. PURPOSE To examine the relationship between physical activity and the number and duration of upper respiratory tract infections. METHODS Undergraduate university students (n=200) completed the Paffenbarger Physical Activity Questionnaire, and a questionnaire which asked the number and length of URTIs within the previous year. Pearson product-moment correlation coefficients were used to examine the relationship between physical activity and URTIs. RESULTS Mean energy expenditure was 2674 ± 548 Kcal per day. Mean number and duration of URTIs was 2.9 ± 2.1 and 6.3 ± 4.4 days respectively. Physical activity level was significantly related to the number of URTIs (r= −0.153, p = 0.03) but not with the duration of URTI (r= −0.101, p = 0.11) CONCLUSION Given the results, it is prudent to recommend moderate participation in physical activity for optimal health benefits.

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.
