Precision Metabolomics Reveal Dynamic Serum Metabolic Changes Driven by Exercise Intensity in Acute Swimming

This study explored the metabolic responses of 42 healthy adults to moderate-intensity continuous training (MICT) versus high-intensity interval training (HIIT) in swimming. Through an exhaustive metabolite analysis employing liquid chromatography-tandem mass spectrometry (LC-MS/MS), we characterized and quantified a vast array of metabolites across both exercise protocols.
