Abstract: BACKGROUND: At present, reducing fat and losing weight has become an eternal topic. Exercise is an important means of lowering fat, and exploring the factors that affect fat metabolism during exercise has become a research hotspot.
OBJECTIVE: To explore the effects of exercise style, exercise intensity, and exercise time on the kinetic characteristics of fat oxidation, summarize the biological mechanism of exercise regulating fat oxidation, explore the application enlightenment of reasonable exercise prescriptions in the prevention and treatment of obesity and other metabolic diseases, and look forward to future research directions in the field.
METHODS: Literature retrieval was conducted in Chinese and English databases such as China Knowledge Network (CNKI), Bailian Cloud Library, PubMed and EBSCO Sports Science Full Text and Researcher and ResearchGate academic social platforms. The search terms included “exercise; fat metabolism; fat energy ratio; fat oxidation rate” in Chinese and English. After initial search, relevant documents were classified, summarized, and refined.
RESULTS AND CONCLUSION: Fat oxidation kinetics is a complex non-linear process, which mainly includes two aspects - fat energy supply ratio and fat oxidation rate, and is affected by exercise intensity, exercise time, exercise mode, exercise level, exercise habits, and body composition. The above-mentioned factors are interrelated and interacted, which experience changes in stages. The molecular biological mechanism of exercise regulating fat oxidation is relatively mature, but the biological mechanism of lactic acid inhibiting fat oxidation is not fully understood. To strengthen the weight loss effect, it is recommended to increase the amount of daily exercise. However, due to the influence of energy protection mechanism, a longer exercise does not indicate a better effect on weight loss. Further studies should be strengthened on the basic application of exercise to control fat oxidation. With the help of proteomics, genomics, and immunoomics tools, we can search for scientific evidence and explore relevant biological mechanisms at the organ system and cell molecular levels, in terms of neuromodulation, immune system control, skeletal muscle metabolism, mitochondrial adaptation, intestinal flora activity and exosomal release.
Key words: exercise, energy metabolism, fat metabolism, fat energy ratio, fat oxidation rate
