Serum metabolomic profiling of exercise response and hyperuricemia status in athletes: a two-part exploratory study.
Article in BMC sports science, medicine & rehabilitation, 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
backgroundWhile high-intensity training improves physiological functions, it also induces significant metabolic stress, leading to a higher incidence of hyperuricemia among athletes compared to the general population. However, existing metabolomic studies on the association between high-intensity exercise and hyperuricemia remain limited, lacking mechanistic exploration of the link between acute exercise stress and chronic disease risk. This study aimed to investigate the potential metabolic associations between acute exercise stress and chronic hyperuricemia through using untargeted metabolomics, while identifying disease-related biomarkers.
methodsThis study employed LC-MS-based untargeted metabolomics. First, a self-controlled intervention was conducted in 41 normouricemic judo athletes to analyze immediate changes in serum metabolites before and immediately after high-intensity resistance exercise. Subsequently, a validation study was performed in a specific cohort to compare the resting metabolomic profiles between athletes with hyperuricemia and normouricemic controls.
resultsHigh-intensity resistance exercise induced significant alterations primarily in glycerophospholipid metabolism. Specifically, lysophosphatidylcholines (LysoPC) were markedly upregulated, whereas phosphatidylcholines (PC) were significantly downregulated immediately after exercise. LysoPC levels showed significant correlations with multiple clinical indices, and a subsequent comparative analysis between hyperuricemic and normouricemic athletes further identified differential metabolites closely associated with hyperuricemia risk.
conclusionsThis study explored the potential metabolic associations between acute exercise stress and chronic hyperuricemia. Key lipid metabolites, represented by LysoPC, hold promise as potential biomarkers. However, owing to the absence of recovery-phase data, the long-term relationship between these transient post-exercise changes and chronic hyperuricemia requires further validation.
