Aim: The aim of study was to effect of short-term consumption of green tea on metabolic cost and substrate oxidation during acute exercise with Fatmax intensity in healthy overweight or obese men.Methods: Fifteen men were studied as cross-examined in one group. First, on the treadmill connected to the gas analyzer, a sports protocol was performed at a speed of 3.5 km/hour, a slope of 1%, for 3 minutes, and after a 2-minute break (first stage), the activity was performed at a speed of 4 km/hour with a slope of one percent (second stage); and then at a speed of 5 km/hour (third stage); and then at a speed of 6 km/hour (fourth stage); And finally, it was implemented at a speed of 6.5 km/hour (4 minutes). Next, the participants consumed 1000 mg/day green tea for a week and came to the laboratory for the second time. Then they consumed placebo for a week and came to the laboratory for the third time. The maximum of fat oxidation (MFO) and the intensity of activity at which MFO occurs (Fatmax) were determined. Results: Between fat oxidation, respiratory exchange ratio, oxygen consumption and energy expenditure in two cases of 7 days green tea consumption and placebo; there was no significant difference (p>0.05).Conclusion: Short-term consumption of green tea before acute exercise at Fatmax intensity has no effect on energy expenditure, oxygen consumption and fat reduction, and its consumption period and dosage should be studied further.
