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

Aim: The purpose of this study was to investigate the relationship between NT-proBNP, galactin-3 and aldosterone variables in endurance skiers after endurance skiing in height.
Method: Twenty four elite endurance skiers (age: 25 years; body fat: 14%) were divided into two groups (Experimental, Control). The skiing program included a skiing route of 8.5 km, a mean time of 65 minutes, and an average intensity of 70-90% of the maximum oxygen consumption. The NT-proBNP values were evaluated by ELISA. A week after skiing, a ride on a treadmill was done with a slope and distance and a similar time with the ski resort. To examine the relationship between the variables studied, Pearson correlation coefficient was used at a significant level of 5% using SPSS version 22 software.
Results: : The results showed that only galatin-3 with NT-ProBNP and NT-ProBNP with aldosterone showed significant correlation in height (P<0.05).
Conclusion: Increasing physiological pressure on the heart caused by exposure to hypoxia and dehydration may lead to changes in the aldosterone and galactin-3 hormone as a fibrotic cell marker.

Aim: Clinical studies indicated that types of exercise might have different effects on cardiac health and function. The effect of strength and endurance exercises-induced cardiac release proteins on its health is no clear. Thus, the aim of the present study was to compare the Galectin-3 and NT-ProBNP levels in strength and endurance elite athletes.
Method: Fifteen elite body builders (mean ± SD age of 23.0 ± 1.4 years and BMI: 24.1 ± 1.4 kg/m2) and fifteen elite endurance runners (mean ± SD age of 21.4 ± 3.0 years and BMI: 21.7 ± 2.0 kg/m2) with at least 3 years of tournament playing were participated in this study as the subject. Anthropometric and body composition parameters were measured. Fasting blood sample was taken for galectin-3 and NT-ProBNP measurements. Data were analyzed by Mann-Whitney U test. Data analyses were performed using SPSS software for windows (version 17) and the level of significance in all statistical analyses was set at P≤0.05.
Results: The results indicated that galectin-3 and NT-ProBNP were higher in the strength elite athletes than the endurance elite athletes were (P<0.05).
Conclusion: In conclusion, it seems that type of exercise is effective on blood galectin-3 and NT-ProBNP concentrations.
