Introduction: This study aims to explore the impact of aerobic exercise and green tea extract consumption on cardiac prognostic markers in men diagnosed with type 2 diabetes.Method: The study involved 32 male participants with type 2 diabetes, aged 50 ± 10.9 years, divided into four groups: 1) green tea (GT), 2) green tea combined with aerobic training (GT+AT), 3) placebo (PL), and 4) placebo combined with aerobic training (PL+AT). Over an 8-week period, the AT protocol was performed for 60 minutes at an intensity of 55-65% of maximum heart rate (MHR) on a treadmill. Green tea extract was consumed at a dosage of 800 mg daily. Serum levels of cardiac markers, including GDF-15 and NT-proBNP, were assessed through blood sampling before and after the intervention. Data were analyzed using ANOVA with repeated measures and Bonferroni's post hoc test.Results: The results indicated a significant decrease in serum levels of GDF-15 and NT-proBNP in the post-test compared to the pre-test in the GT, GT+AT, and PL+AT groups (P

Introduction: The aim of the present study was to investigate the effect of MCT1 A1470T polymorphism (rs 1049434) on one repetition maximum muscle strength in young athletes of the speed and endurance strength group in the chest press and squat-smith tests.Methodology: 49 young trained male athletes with average age (24.22±5.54 years), height (178.57±8.91 cm), and weight (75.32±13.31 kg) were included in this research with the entry criteria. Muscle strength was calculated during one session using a maximum repetition test in two parts of the upper body (chest press test) and lower body (squats) for each subject. ARMS-PCR method was used to determine the genotype of the samples.Results: The results showed that there is a significant difference between the genotypes of the MCT1 polymorphism in one repetition of the maximum muscle strength of the Scott-Smith test in athletes (F=51.3, p=0.038) that the TT genotype with the highest strength in the test Scott Smith was with him. LSD post hoc test showed that subjects with genotype (TT+AT) have more strength compared to subjects with genotype (AA+AT). In the strength group between genotypes (AA and TT) in one repetition of maximum Scott-Smith muscle strength, the difference It was significant (p=0.047, F=3.54) and people with TT genotype had the highest strength in the Scott-Smith test.Conclusion: The TT genotype of the MCT1 polymorphism has been associated with the lower body muscle strength of athletes and the effect of this genotype was evident in the athletes of the strength group.

Aim: Adipokines are molecules secreted from adipose tissue that are related to insulin resistance, metabolic syndrome, diabetes and cardiovascular diseases. Therefore, the effect of 8 weeks of resistance training along with green tea extract (GTE) supplementation on the concentration of adipokines apelin and chemerin in obese women was investigated.Method: Thirty untrained women with a body mass index (BMI) above 30 kg/m2 were selected from among obese women using a randomized, double-blind, placebo-controlled design method and were divided into three groups including training and green tea extract (GT), training and placebo consumption (PT) and green tea extract consumption (G). GT and G groups took 600 mg.kg-1 of GTE daily and PT group also took 600 mg of placebo for 8 weeks. The resistance training program consisted of 3 sessions per week for 8 weeks (60-70 minutes with an intensity of 65% to 80% of a one repetition maximum). Serum level of adipokines was measured using ELISA method.Results: The results of ANOVA with repeated measures indicate a significant decrease in serum levels of apelin and chemerin in GT and PT groups compared to G. Also, a significant decrease in the level of these adipokines was observed in the post-test compared to the pre-test in all three groups. Conclusion: 8 weeks of GTE intake and resistance training decreased inflammatory adipokines in obese women, and the combinatory effect of resistance training with GTE was more effective than the other two conditions.
