Rapid weight loss practices and methods among Mongolian judo athletes.
Article in Physical activity and nutrition, 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
purposeRapid weight loss is prevalent and potentially hazardous in combat sports; however, evidence among Mongolian athletes remains limited. This study characterized rapid weight loss practices among Mongolian judo athletes and compared behavioral practices and social influences between Limited-Method-Use and Combined-Method-Use profiles.
methodsThis cross-sectional study included 100 competitive Mongolian judo athletes. Of the 81 athletes who reported rapid weight loss, hierarchical cluster analysis classified 57 as Limited-Method-Use and 24 as Combined-Method-Use based on 12 weight-cutting modalities.
resultsPre-competition rapid weight loss was reported by 81.0% of participants. Compared with the Limited-Method-Use group, the Combined-Method-Use group had greater body mass reduction (6.86% vs. 5.25%, p = 0.001) and post-competition body mass regain (6.62% vs. 5.04%, p = 0.001). The Combined-Method-Use group relied heavily on multifaceted dietary restrictions and thermal dehydration methods [sauna, fluid restriction, and plastic suit training (all p < 0.05)]. Regression analysis identified total body mass reduction percentage as the sole significant predictor of weight regain (β = 0.647, p < 0.001). Coaches and teammates were the primary social influences, whereas healthcare professionals had limited influence.
conclusionRapid weight loss is deeply embedded as a normative practice within the Mongolian judo community, with many competitors adopting aggressive, dehydration-driven methodologies. The strong association between weight cuts and severe weight regain highlights the hazardous nature of these practices. These insights underscore the critical need for evidence-based sports nutrition education and preventative screenings targeting athletes and coaching staff.
