Effect of the ingestion of green tea on the fat oxidation in the sedentary and the exercise
Abstract
The green tea, wide consumed for the eastern population, is gotten from leaves not leavend of the plant, Camellia sinensis. This tea is rich in structures called catechins, that are phenolic composites (flavanols) with antioxidant action and related to the found therapeutical effect in this tea. The catechins come being searched for assisting in the maintenance and reduction of body weight, in decreasing of visceral fat, the reduction of diet intake, the increase of the resting energy expenditure, in the stimulation of fat oxidation and control of triglyceride, cholesterol, glucose, insulin and leptin in plasma. Studies show that the thermogenesis effect of the green tea not only seems to be exerted by the caffeine of the green tea, but also, the catechins too, exerting a synergic effect when associates these two substances. The physical exercise and supplementation of green tea in set seem to increase the fat catabolism skeletal muscle in rats, with lesser using of muscle glycogen, thus contributing, for the increase of performance in the exercise of endurance. This revision has for purpose to indirectly present the studies most recent of the effect of the green tea in the fat oxidation and parameters associates to this in the sedentary and the exercise. The results are controversial, being necessary more research in this field to consolidate the findings until today joined.
