Effects of exercise modalities on cognitive and muscle function in older adults with cognitive impairment: a systematic review and meta-analysis.
Synthesis in Scientific reports, 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
This study examined the effects of different exercise interventions on cognitive and muscle function in older adults with mild to moderate cognitive impairment or dementia. Randomized controlled trials published up to May 2025 were identified from four databases (Cochrane Library, PubMed, EMBASE, and Web of Science). Aerobic, resistance, and combined exercise interventions were included. Study quality was assessed using the Cochrane RoB 2 tool, and random-effects meta-analyses were conducted. Fourteen studies involving 1,097 participants were included. The meta-analysis indicated that aerobic exercise was mainly associated with improvements in cognitive outcomes, whereas resistance exercise primarily enhanced muscle strength and physical performance. Interventions combining aerobic and resistance components showed benefits across both cognitive and muscle function domains. Although the included studies were few and heterogeneous, the overall pattern suggests potential modality-specific effects, whereby aerobic exercise may support cognitive function, resistance exercise may enhance muscle strength and physical performance, and combined exercise may provide benefits for both cognition and muscle function in older adults with mild to moderate cognitive impairment or dementia. However, the certainty of evidence ranged from low to very low, and these findings should therefore be interpreted with caution. These findings highlight the value of selecting exercise modalities based on targeted functional goals.PROSPERO registration: CRD420251051222
