Aerobic physical activity, cardiorespiratory fitness, and non-communicable diseases risk in older adults: a systematic review.
Synthesis in BMC geriatrics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundNon-communicable diseases (NCDs) account for an estimated 80% of the healthcare burden among older adults globally. Aerobic physical activity (PA) contributes to functional mobility, increased bone and muscle strength, prevention of illness and quality of life; however, PA is not yet a fully realised aspect of geriatric care.
objectiveTo review recent evidence for the impact of aerobic PA and cardiorespiratory fitness (CRF) on mortality and NCD outcomes in adults aged ≥ 65 years.
methodsFollowing PRISMA guidelines, we performed a systematic search of the Scopus, Cochrane Library, PubMed and Web of Science databases, published between 2016 and February 2024.
resultsThe 94 included studies (reported in 104 individual manuscripts) included 46 cross-sectional, 24 longitudinal, 7 cross-sectional/longitudinal, 1 intervention/cross-sectional, and 16 interventions studies. PA and CRF were consistently associated with reduced all-cause mortality in longitudinal studies. Most included studies reported inverse associations between measures of PA and cardiovascular disease (CVD, n = 14 of 16 studies) risk and measures of dysglycaemia (n = 12 of 16 studies). Obesity/adiposity, blood pressure, lipids, and metabolic syndrome (MetS) were not consistently associated with aerobic PA. While aerobic PA interventions generally improved depression outcomes, longitudinal studies showed inconclusive results. Observational evidence suggests an association between PA and frailty, but less consistently with falls.
conclusionThis review suggests a beneficial association between aerobic PA and all-cause mortality, CVD, dysglycaemia, and frailty, with inconsistent evidence for associations with obesity, dyslipidaemia, hypertension, MetS, depression, and falls. Given the inconsistent findings for key metabolic outcomes, future research is needed to address outstanding and understudied questions around risk reversibility and time to benefit for PA interventions, as well as identifying target groups who benefit more from PA and tailoring interventions to these groups. Further longitudinal studies are also needed to determine the optimal frequency, duration, and intensity of aerobic PA for mitigating NCD risk in older adults.
