Aerobic Training Restores Arterial Baroreflex Sensitivity in Older Adults With Type 2 Diabetes, Hypertension, and Hypercholesterolemia
Bibliographic record
Abstract
OBJECTIVE: Lowered baroreflex sensitivity (BRS) predicts mortality and occurs with increasing age and diabetes. We examined whether aerobic exercise could restore arterial BRS in adults at high cardiovascular risk (diabetes, geriatric age group, hypercholesterolemia, and hypertension). DESIGN: Randomized, controlled, single-blind study. SETTING: VITALiTY (Vancouver Initiative to Add Life to Years) Research Laboratory. PARTICIPANTS: Thirty-nine older adults (mean age, 71.5 +/- 0.7 years) with diet-controlled or oral hypoglycemic-controlled type 2 diabetes, hypertension, and hypercholesterolemia. INTERVENTIONS: Subjects were recruited to each of 2 groups: an aerobic group (3 months of vigorous aerobic exercise as defined by 80% to 85% of maximal heart rate), and a nonaerobic (no aerobic exercise) group. Exercise sessions were supervised by a certified exercise trainer 3 times per week. MAIN OUTCOME MEASURES: : Baroreflex function was assessed using the spontaneous baroreflex method. Main outcome measures included BRS, BRS(up), BRS(down), and [latin capital V with dot above]o(2)max. RESULTS: The aerobic group demonstrated an increase in BRS that was not demonstrated in the nonaerobic group (+60.9 +/- 23.5 vs +2.2 +/- 7.9%; P = 0.010). CONCLUSIONS: Our findings indicate that a relatively short aerobic exercise intervention can reverse functional impairments of the arterial baroreflex function in older adults at high cardiovascular risk.

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.
