TRACKING OF PHYSICAL FITNESS FROM CHILDHOOD TO ADULTHOOD
Bibliographic record
Abstract
The purpose of the present study was to investigate tracking of physical fitness: muscular strength (handgrip), endurance (sit-ups), and aerobic fitness (PWC/kg) from childhood to middle age. A sub-group of 95 women (57 experimental and 38 control subjects) and 96 men (56 experimental and 40 control subjects) was randomly selected from original participants in the Trois-Rivières growth and development study. Data was gathered during the period 1970–1977 and during a recall performed in 1996–1997. Tracking between 10, 11, 12 and 35 years was measured by correlation analysis. Correlation coefficients for grip strength increased slightly at each interval 10–35, 11–35 and 12–35 years from 0.56 to 0.63 in women and from 0.45 to 0.61 in men (P < 0.001). Tracking for sit-ups was less consistent, increasing from 0.29 to 0.38 for women and 0.23 to 0.54 for men (P < 0.05), respectively, over the same intervals. Tracking of PWC/kg between 11 and 35 years was significant but low, both in women (r = 0.24) and in men (r = 0.34) (P < 0.05). We conclude that physical fitness components continually used over lifetime, such as grip strength, are relatively stable. However, components that are less likely to be used continually, such as cardiorespiratory fitness and abdominal endurance show less consistent tracking. The latter fitness components should be targeted for lifetime intervention programs. Supported by CFLRI #951R110

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.
