Obesity is recognized to be a risk factor for heart failure (HF), and adversely impacts on cardiac structure and function. Therefore, it is not surprising that obesity markedly increases the prevalence of HF and causes to reduce serum levels of Irisin and KLF15. Studies have indicated association between serum Irisin and KLF15 with many major chronic diseases including cardiovascular diseases (CVDs). Clinical studies have demonstrated that both KLF15 and irisin are related to HF.

This study aims to the effect of combined training on Adipolin and Myostatin serum levels and reduction of HF risk factors.
Twenty obese men (age = 34.8 ± 3years) were divided into 2 groups: combined training (CT [strength + aerobic], n =10), and control group (CG, n =10). Aerobic section included of 8 weeks (3 sessions a week) training from 50% maximum heart rate progressed gradually to 70% and time from 7.5 minutes to 22.5 minutes. Strength group performed 3 sessions per week for 8 weeks (3 sets with 10 repetitions, 30-70% 1RM). All values were measured 24 hours before start and 48 hours after the end of training period. The findings analysed by independent t-test and ANOVA in SPSS software (v.22) .
The results showed that 8-week CT training significantly increase KLF15 (p=0.036), Irisin (p=0.001) and HDL (P=0.016) and significantly decrease Insulin resistance (p= 0.006), TG (P=0.001), VLDL (P=0.017), fat percentage (P=0.001) and weight (P=0.008). But LDL (P=0.077) levels were not significantly reduced compared to pre-test and CG group.
Our results have showed that 8 weeks combined training has an important role in increase and adjustment of prevent risk factors of cardiovascular diseases in obese men.
