Abstract: With the continuous development of the equine industry,the research on the athletic capabilities of horses has increasingly drawn attention.As an emerging research methodology,metabolomics technologies offer a novel tool for in-depth exploration of the metabolic alterations in horses during exercise.The metabolomics technologies mainly encompass nuclear magnetic resonance (NMR),gas chromatography-mass spectrometry (GC-MS),liquid chromatography-mass spectrometry (LC-MS),etc.,which have been extensively applied in horse sports-related research,covering multiple fields such as sports traits,exercise physiology,and sports-related diseases,which include revealing the dynamic adaptation mechanism of energy metabolism in sports types such as horse speed and endurance,studying the metabolic mechanism of improving the exercise performance of horses through training,identifying the characteristic metabolites of horse sports diseases and providing targets for diagnosis and treatment,and exploring the metabolic mechanism of nutritional intervention and antioxidant strategies on the exercise capacity and body recovery of horses.In the review,the authors systematically introduce the basic concepts and research methods of metabolomics,and focuse on the research results of horse exercise-related metabolomics.At the same time,the metabolic pathways of carbohydrates,proteins and amino acids,and lipids closely related to horse exercise,as well as their dynamic adaptive mechanisms during exercise are summarized.The integration of metabolomics and multi-omics is expected to lead to significant breakthroughs in horse sports-related research.
