Effect of two different types of exercise volumes on exercise capacity, physical activity and quality of life in subjects undergoing percutaneous coronary intervention: a pilot study
Bibliographic record
Abstract
Introduction Phase II of cardiac rehabilitation includes 36 sessions of exercise developed over 12 weeks, an intervention format that seems to be based on historical practice and not on scientific evidence. The objective was to evaluate the effect of two types of exercise volumes on exercise capacity, physical activity levels, and quality of life in subjects undergoing percutaneous coronary intervention. Methods A randomized controlled clinical trial was performed in 17 subjects, who were randomly assigned to two groups. The first (<i>n</i> = 7) was trained for eight consecutive weeks, and the second (<i>n</i> = 10) for 12 weeks. The six-minute walk test, the International Physical Activity Questionnaire, and the SF-36 were applied before starting the cardiac rehabilitation program at 8 and 12 weeks. Results No significant differences were found between the intervention groups. The rise of VO2max was only significant in the 8-week group. Both groups improved the distance walked and sedentary behaviour. The 12-week intervention group improved the quality of life, specifically in physical functioning, and the 8-week intervention group in the domains of social function, physical, and emotional role. Additionally, the percentage of participants meeting physical activity recommendations was higher in the 12-week cardiac rehabilitation group. Conclusions The implication for the practice is that the exercise traditionally used in cardiac rehabilitation shows early changes in exercise capacity and quality of life. The results of the levels of physical activity and sedentary behaviour improved after 12 weeks of rehabilitation without the presence of adverse events.

How this classification was reachedexpand
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.
