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.

Background and Aim: The aim of this study was to investigate the effect of 6 weeks of CXWORX training along with nettle supplement consumption on lipid profile, C-reactive protein and some body composition indicators of overweight and obese women. Methods: The current research was semi-experimental with a pre-test and post-test design. For this purpose, 48 overweight and obese women with an age range of 20-40 years and a body mass index (BMI) between 25-34 kg/m2 were purposefully selected and divided into 4 groups: exercise + nettle, exercise + placebo, nettle and Placebo was divided. All measurements were done one stage before the start of the course and another stage after the course was finished. After collecting the data, the data were analyzed with SPSS software, and Shapiro-Wilk, T-correlated tests and one-way analysis of variance were used at a significance level of p<0.05. Results: The results showed that after 6 weeks of intervention, the levels of triglycerides (p=0.105), total cholesterol (p=0.995), high-density lipoprotein (p=0.112), and low-density lipoprotein (0.506) p = ) and C-reactive protein (p = 0.965) did not show any significant difference between the research groups. But there was a significant difference in body weight (p=0.004), body mass index (p=0.010) and ratio of waist circumference to hip circumference (p=0.000) among research groups. Conclusion: 6 weeks of CXWORX training along with nettle supplementation can reduce body weight, body mass index and waist to hip ratio.
