An exercise-associated gut microbiota signature enhances endurance performance: A study combining a human cohort and a mice FMT model.
Article in PloS one, 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
backgroundThe gut microbiota is closely related to exercise, but the interrelationship between the two remains elusive. In this study, we aimed to explore differences in the gut microbiota between young adults with exercise and sedentary lifestyles. In addition, we evaluated the effects of gut microbiota from these different lifestyle populations on endurance exercise capacity.
methodsThe exercise status and nutritional characteristics of young adults were evaluated by PARS-3 and food frequency questionnaires. The gut microbiota of young adults from exercise and sedentary lifestyle groups was analyzed by 16S rRNA analysis. Subsequently, we performed fecal bacteria transplantation (FMT) from the human donors into mice and evaluated the effects on their endurance exercise capacity.
resultsThe exercise group exhibited significantly higher gut microbiota diversity compared to the sedentary group. Several beneficial bacteria, including Veillonella, Faecalibacterium, and Bacteroides, were enriched in the exercise group. The FMT experiment confirmed that mice receiving microbiota from the exercise group showed significantly improved endurance exercise capacity.
conclusionYoung people who exercise regularly possess a more diverse gut microbiota enriched with beneficial bacteria. This exercise-associated microbiota has the potential to directly improve exercise capacity.
