Abstract :

This review investigates the synergistic effects of aerobic physical activity and green tea supplementation on fat metabolism, particularly in overweight or obese adults. Several studies have shown that green tea can significantly improve thermogenesis and fat oxidation. This condition is because it contains many bioactive compounds, including caffeine and catechins. These effects are further exacerbated when combined with aerobic activities such as cycling, jogging, and swimming, which are commonly recognized for their ability to enhance cardiovascular health and increase energy expenditure. The current study delves into recent research on the interaction of green tea, particularly its catechin epigallocatechin gallate, with the body's metabolic processes. Green tea increases fat availability during exercise and prolongs fat decomposition by inhibiting enzymes such as catechol-O-methyltransferase. Additionally, caffeine enhances energy expenditure, which facilitates the prolonged oxidation of fat following exercise. Studies suggest that individuals who consume green tea before moderate-intensity aerobic exercise experience significantly enhanced fat burning compared to exercise alone. This combination offers a comprehensive, natural alternative to pharmacological interventions for weight management, promoting both fat loss and improved metabolic health. The potential cardiovascular protection, reduced inflammation, and enhanced insulin sensitivity of green tea are reviewed in relation to its broader health benefits. Furthermore, it investigates the implications for athletes, suggesting that green tea can boost endurance by optimizing fat utilization during extended aerobic activities. In conclusion, this review emphasizes the potential of integrating aerobic exercise with green tea supplementation as a successful approach to facilitating sustainable weight management, improving overall health, and enhancing fat metabolism.
