Substrate Oxidation Changes During Exercise After White Tea Consumption in Obese Men

The purpose of this study was to evaluate the changes in substrate oxidation during exercise with white tea consumption in obese men. Ten obese young men (age 19.00 ± 0.47 years, height 181.80 ± 4.32 cm, weight 104.20 ± 8.84 kg, BMI 31.20 ± 1.93 kg/m2, body fat percent 25.80 ± 2.62 %), take 500 ml of water or 500 ml of white tea one week apart after 8 h fasting in crossover and counterbalance model. One hour after use, while the gas analyzer was connected to them, they carried out an incremental exercise to exhaustion on a treadmill. The rate of fat and carbohydrate oxidation during exercise test were measured using indirect calorimetry. For each subject, the maximum fat oxidation (MFO) and the intensity of the MFO occurs (FATmax) were determined. Paired Sample t test showed that MFO (p = 0.011), and fat oxidation in the third stage (p = 0.023) in terms of white tea consumption was significantly higher than water intake. There was no significant difference in FATmax, time to exhaustion, maximum heart rate and maximum oxygen consumption between the two conditions. It seems that taking white tea one hourbefore exercise can increase fat oxidation in obese men.
