Background Green tea (GT) consumption may influence fat oxidation (FO), body composition and blood lipid profile in human subjects. Therefore, this study aimed to review the current literature regarding the interactive effect of aerobic and resistance training with GT ingestion on these parameters. Methods Electronic searches were performed in Google Scholar, PubMed, Elsevier, Science Direct, and national databases. Only studies on human subjects that included GT intervention and aerobic or resistance exercise from any date to May 30, 2021 were reviewed. Results Twenty-seven papers (n = 831 participants) were included. From these, 12 studies addressed the acute or short-term effect of GT consumption on substrate oxidation during exercise, 2 studies assessed the long-term effect of GT consumption and aerobic exercise on substrate oxidation during exercise, 9 studies examined the short-term or long-term effects of GT intake and aerobic exercise on substrate oxidation or cardiometabolic risk factors, and 4 studies investigated the long-term effects of GT consumption and resistance training on substrate oxidation or cardiometabolic risk factors. Conclusions Short-term consumption of GT may have positive metabolic effects during moderate-intensity exercise in inactive people or those who exercise recreationally. Likewise, a combination of moderate-intensity aerobic training and GT consumption for a minimum period of 8 to 10 weeks can increase FO during exercise in healthy individuals. Regular resistance training combined with GT consumption may have potential benefits in enhancing body composition, lowering triglyceride, and increasing high-density lipoprotein in sedentary obese/overweight people.
