Comparative effects of light or heavy resistance power training for improving lower extremity power and physical performance in mobility-limited older adults.
Trial report in The journals of gerontology. Series A, Biological sciences and medical sciences, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04762342 (Power Training in Older Multiple Sclerosis Patients), which is not on this map. Cited by 50 papers, 7 of them syntheses that pooled it.
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.

Abstract
backgroundWe compared the effects of two uniquely different lower extremity power training interventions on changes in muscle power, physical performance, neuromuscular activation, and muscle cross sectional area in mobility-limited older adults.
methodsFifty-two subjects (78±5 years, short physical performance battery score: 8.1±1) were randomized to either 16 weeks of progressive high velocity resistance training performed at low external resistance (40% of the 1-repetition maximum [1-RM] [LO]) or high external resistance (70% of 1RM [HI]). Both groups completed three sets of leg and knee extension exercises at maximum voluntary velocity, two times per week. Neuromuscular activation was assessed using surface electromyography and muscle cross sectional area (CSA) was measured using computed tomography.
resultsAt 16 weeks, LO and HI exhibited significant and similar within-group increases of leg extensor peak power (~34% vs ~42%), strength (~13% vs ~19%), and SPPB score (1.4±0.3 vs 1.8±0.3 units), respectively (all P < .03). Improvements in neuromuscular activation occurred in LO (P = .03) while small gains in mid-thigh muscle CSA were detected in LO (1.6%, P = .35) and HI (2.1%, P = .17). No significant between-group differences were evident for any measured parameters (all P > .25).
conclusionsHigh velocity resistance training with low external resistance yields similar improvements in muscle power and physical performance compared to training with high external resistance in mobility-limited elders. These findings may have important implications for optimizing exercise interventions for older adults with mobility limitations.
