THE LONG VIEW: COMPARING OUTCOMES OF CLASS- AND HOME-BASED PHYSICAL ACTIVITY PROGRAMS FOUR YEARS LATER
Bibliographic record
Abstract
Both class- and home-based (CB; HB) physical activity programs are effective in increasing functional performance, physical fitness and other health outcomes in older adults. Direct comparisons of program effectiveness have been equivocal and few have examined outcomes beyond the 12-month mark. 50+ in motion was a randomized clinical trial comparing the effectiveness of a CB and HB physical activity program for sedentary older adults with chronic health conditions. The intervention consisted of a 3-month intensive phase and a 9-month follow-up phase. Data were collected from 172 participants at baseline, 3-, 6-, 12-months, and then annually for a total of 48 months. Outcomes included cardiovascular fitness, functional performance, body composition, quality of life, and health services utilization. In both programs, improvements in most outcomes were sustained beyond 12-months with some extended through the entire follow-up period. There were no differences in health services variables between the programs until the final year.

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.
