Physical and Cognitive Effects of High-Intensity Interval or Circuit-Based Strength Training for Community-Dwelling Older Adults: A Systematic Review
Bibliographic record
Abstract
ABSTRACT Background High-intensity interval or circuit-based strength training utilizes brief intense periods of strengthening exercises interspersed with rest/light activity or performed in a continuous circuit. The physical and cognitive effects of this time-efficient approach in community-dwelling older adults have not been systematically reviewed. Objectives To determine the effects of high-intensity interval or circuit-based strength training interventions on physical and cognitive functioning for community-dwelling older adults, and the associated adherence, retention, and adverse event rates. Methods Six databases will be searched from inception to November 2021; MEDLINE, EMBASE, CINAHL, AgeLine, SPORTDiscus, and Web of Science. To assess physical and/or cognitive functioning effects, randomized and quasi-randomized controlled trials (RCTs and Q-RCTs) of high-intensity interval or circuit-based strengthening interventions in community-dwelling older adults, utilizing any comparator, will be included. The above criteria will be extended to include non-randomized study designs to assess adherence, retention, and adverse events. All screening, data extraction and risk of bias will be assessed by two independent reviewers. Risk of bias will be assessed utilizing the Cochrane RoB 2 tool for randomized and ROBINS-I for non-randomized studies. Qualitative synthesis will be used to present information on adherence, retention, and adverse event rates. Qualitative and/or quantitative synthesis will be used to present physical and cognitive functioning effects depending on which method is deemed appropriate for the various outcomes. Conclusion This systematic review will be the first to summarize the physical and/or cognitive effects, adherence, retention, and adverse events reported in high-intensity interval and circuit-based strengthening interventions for community-dwelling older adults.

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.
