Abstract

ABSTRACT
           Background and objectives: The present study was designed to determine the effect of blood flow restriction training (BFRT) on follistatin to myostatin ratio, body composition and anaerobic power of trained volleyball players.
           Methods: Eighteen trained volleyball players were randomly assigned into two study groups: resistance training with blood flow restriction (BFRT; n=9) and resistance training without blood flow restriction (WBFRT; n=9). The subjects performed trainings three sessions a week, for eight weeks. In each session, barbell squat, leg extension, leg curl and dumbbell lunges were performed in three sets of 15 repetitions, with rest intervals of 30 seconds. Serum follistatin and myostatin concentrations, body composition and anaerobic power were assessed before and after the study. Data were analyzed using the paired sample t-test, Wilcoxon test, independent sample t-test and Mann-Whitney U test. All statistical analyses were done in SPSS (version 22), and a P-value of less than 0.05 was considered statistically significant.
           Results: Follistatin levels increased significantly (P=0.001), while myostatin levels decreased significantly in both groups (P=0.001). Follistatin to myostatin ratio increased significantly in both groups (P=0.001). Although body fat percentage decreased in both groups, it did not differ significantly between the two groups (P=0.28). Moreover, anaerobic power increased significantly in both groups (P=0.001), but this increase was more profound in the BFRT group (P=0.001).
           Conclusion: Based on our findings, blood flow restriction can be applied as remarkable approach to boost body adaptation responses to resistance training.
           KEYWORDS: Resistance training, Myostatin, Follistatin, Blood flow restriction.

Abstract

Background and objectives: Previous investigations have shown that physical activity can improve insulin sensitivity and body composition by reducing the concentration of inflammatory biomarkers. The study aimed at evaluating effects of eight weeks of resistance training and high-intensity interval training on adropin, blood glucose markers, and body composition in overweight females.
Methods: sixteen overweight females (mean age: 30 ± 4.3 years and body mass index= 29 ± 2.6 kg/m2) were randomly assigned to a resistance training group (n=8) and a high-intensity interval training group (n=8). Participants in both groups trained three times a week for eight weeks. Body composition and serum level of blood markers were determined at baseline and after the last training session.
Results: Body mass, body fat percentage, and waist-hip ratio decreased significantly in both groups (p<0.05). VO2max significantly increased in both groups, while the changes in the resistance training group were greater than in the high-intensity interval training group (p<0.05). Insulin and HOMA-IR concentrations decreased significantly in the resistance training group (p<0.05).
Conclusion: Eight weeks of both training procedures could significantly decrease body composition markers. However, the training duration was not sufficient to alter fating blood sugar or adropin concentrations.
