The Effects of Physical Activity Enjoyment on Sedentary Older Adults' Physical Activity Attitudes and Intentions1
Bibliographic record
Abstract
This pilot study examined the effects of 2 types of acute physical activity bouts on enjoyment and subsequent change in attitudes and intentions regarding physical activity. Participants were 41 sedentary, older men and women (M age = 75.4 years) randomized to a single bout of walking plus either (a) 2 sets of a resistance‐training circuit performed on weight machines (Weights); or (b) 1 set of the resistance circuit plus 1 set of strength‐based activities of daily living (Weights + ADL). The Weights condition enjoyed their bout more, and enjoyment mediated subsequent changes in attitudes. Both conditions increased their physical activity intentions. However, contrary to the tenets of the theory of planned behavior, increased intentions were not mediated by improved attitudes toward physical activity. These findings suggest that single bouts of activity can differentially affect sedentary older adults' thoughts toward being active in their daily lives.

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.
