The Effect of Eight Weeks Resistance Training With and Without Vascular Occlusion on Physical Fitness Indexes, Growth Hormone, and Insulin-like Growth Factor in Male Judokas

Purpose: The present study was conducted to investigate the effect of 8 weeks resistance training with and without vascular occlusion on physical fitness indexes, growth hormone, and Insulin-like Growth Factor 1 (IGF-1) in male judokas. Methods: In this quasi-experimental study, 20 male judokas were divided into two groups: 1. Traditional resistance training along with judo training without blood vascular occlusion (n=10); and 2. Resistance training group along with judo training with blood vascular occlusion (n=10). Resistance training schedule included 3 sessions per week, each session lasting 45 to 60 minutes for 8 weeks. The comparison of means within and between groups was done by paired sample t test and ANCOVA test, respectively. All statistical analyses were performed with SPSS V. 20. Results were significant at P≤0.05. Results: Results showed that cardio respiratory endurance, anaerobic power, speed, agility, muscular endurance and power, changed significantly in both resistance groups with and without vascular occlusion. Growth hormone and insulin-like factor growth changed significantly. Concerning intergroup means changes in variables of cardio respiratory endurance (P=0.03), anaerobic ability (P=0.02), speed (P=0.03), agility (P=0.03), muscular endurance (P=0.007), power (P=0.01), growth hormone (P=0.01) and insulin-like growth factor(P=0.03), there was a significant change between two groups of resistance training with vascular occlusion and without vascular occlusion. Conclusion: Eight weeks of resistance training with and without vascular occlusion, improved motorphysical fitness indexes and increased growth hormone and insulin-like growth factor in male judokas.
