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.
