Obesity is one of the epidemic problems in the all over the world, which has had crucial effects on various aspects of the lives communities. Therefor noticeable part of resent researches has been associated with obesity, related diseases, and prevention and treatment strategies. The purpose of this study was the effect of short-term green tea (matcha) supplementation on fat oxidation rate during exercise in obese women.
This quasi-experimental study was carried out as pre-test and post-test. Subjects were 10 obese and non-active women with an average age of 36.8 ± 4.7 years old, 160.1 ± 4.7 mm high, 83.5 ± 15.3 kg weight and 32.6 ± 5.9 kg/m2 in BMI respectively.
Participants consumed a daily dose of 1000 mg per day for 7 days. Before and after the supplementation with 12 hours of fasting, plasma glycerol were measured. Furthermore, in order to measure the maximum lipid oxidation, subjects completed a progressive exercise test before and after supplementation. During the test, the volume of oxygen and carbon dioxide was measured. Then, with the assumption that the amount of urine nitrogen is negligible, the fat and carbohydrate oxidation rate was calculated using the equation analysis. Statistical analysis was performed using SPSS software and Shapiro Wilk test and to compare intra-group mean t and correlation analysis of variance with repeated measure. The significance level was considered as P≤0.05.
The results of this study showed that the short-term use of Macha supplement not significant effect on FATmax, (p= 0/481) and MFO(p= 0/587). Macha supplementation alone did not have a significant effect on plasma glycerol levels but exercise alone reduced plasma glycerol levels. The findings showed that short-term consumption of green tea in the amount of 1 gm per day cannot lead to increases lipolysis and Fat oxidation rate of obese women.
