Abstract :
the purpose of this research was to compare the effect of resistance training with vascular obstruction on ghrowth hormone, Strength, Muscular endurance, power and body fat percentage in male bodybuilders. For this research twenty-four bodybuilders with at least two years of training experience and the age average was 25.6 ± 1.9 years and the weight was 79.28 ± 6.28 kg and the BMI was 24.69 ± 1.8 kg / m2 were chosen and were divided into two groups;one group, resistance training with vascular obstruction and the other group, resistance training without vascular occlusion. Both groups performed an exercise program consisting of five sessions per week, two of which were dedicated to training the arm muscles for six weeks. before and after the six weeks training plan a blood test was taken from volunteers;the body fat percentage was also measured with caliper. Muscular strength and endurance were assessed using weights and bodybuilding equipment and hand muscle strength was assessed using the Madison Ball throw test with both hands forward.The results said showed that resistance training with vascular obstruction had significant effect on the muscular endurance of biceps(P=0/005) and triceps(P=0/007) but had no effect on growth hormone (P=0/607), strength(P=0/674), power(P=0/41) and body fat percentage(P=0/382). Due to the fact that increasing strength and muscle volume in bodybuilding is considered by athletes in this popular field, The use of blood flow obstruction is not recommended for athletes with experience in this sport in training design.
