Background: Uncertainty persists regarding the dose–response association between exercise exposure and blood pressure (BP) control in chronic kidney disease (CKD). This dose–response network meta-analysis examined whether different exercise modalities and model-estimated metabolic-equivalent exposure levels were associated with changes in systolic BP (SBP) and diastolic BP (DBP). Methods: Exercise dose was estimated as metabolic equivalents of task minutes per week (MET-min/week) from reported session duration, frequency, and intensity. Primary outcomes were changes in SBP and DBP, with exploratory subgroup analyses by dialysis status, baseline BP, and intervention duration. Results: The analysis included 26 randomized controlled trials (1218 participants). Aerobic exercise was associated with lower SBP, with the greatest model-estimated reduction at 880 MET-min/week (MD, −7.73 mm Hg). Resistance and mind–body exercise also showed model-estimated reductions, whereas combined aerobic-resistance training was not statistically significant. Dose–response estimates differed by dialysis status and intervention length, but several subgroup estimates were based on sparse data and wide uncertainty. Evidence certainty ranged from very low to high (CINeMA). Conclusions: Exercise interventions may be associated with BP reduction in CKD, but the identified MET-min/week ranges should be interpreted as exploratory, model-derived estimates rather than validated therapeutic thresholds. Better reported randomized trials are needed to confirm dose ranges, safety, adherence, and tolerability in dialysis and non-dialysis CKD populations.

Objective: This study assessed the blood-pressure effects of various exercise regimens in middle-aged and older adults with type 2 diabetes, considering baseline levels, to clarify dose–response relationships for personalized exercise guidance. Methods: We conducted a dose–response network meta-analysis. Systematic searches were performed in Web of Science, EMBASE, PubMed and Cochrane Library. Baseline blood pressure was modelled as an explanatory variable via meta-regression. Thirty-six eligible RCTs of physical-activity interventions in older adults with type 2 diabetes reporting blood-pressure outcomes were included. Results: In stage 1–2 hypertension, mind–body activities were associated with the greatest systolic blood-pressure reduction and appear to be the most effective intervention based on available evidence. For diastolic blood pressure, combined aerobic-resistance training was effective in stage 1 hypertension. Dose–response analysis indicated that clinically meaningful reductions occur at modest volumes (668 and 657 MET-min/week for systolic and diastolic pressures, respectively), aligning with the lower end of international activity guidelines. Conclusions: Individualized exercise prescription based on baseline blood pressure may offer a useful non-pharmacological strategy for hypertension management in older adults with type 2 diabetes. By quantifying the required activity dose, this work provides an evidence base for integrating structured exercise into precision care for this high-risk population.
