Background:­ Exercise  training with blood flow restriction is effective in improving various physical factors and can be a unique as well as beneficial method in the field of medicine. The aim of the current study was comparison the effect of one session of resistance training with and without blood flow restriction of arm on serum levels changes of growth hormone and lactate of athlete females. 
Materials and Methods: The present study is a Clinical trial with pretest-posttest type. 30 basketball players aged 23-30 years were randomly divided into three groups: traditional resistance training (intensity 80%) resistance training with vascular occlusion (intensity 30% 1RM) and control group. Training with one set of 30 reps Started and with two sets repeated until exhaustion ended. The rest time was 30 seconds. Blood sampling prior to and immediately after the workout took place. Paired t-test for comparisons within group changes and one-way analysis of variance was used to compare between group changes. 
Results: Post-test findings in the intra-group changes indicated a significant increase in the serum level of growth hormone in the two training groups, but the amount of lactate ion in all three groups significantly reduced compare to the pre-test (P<0.05). In between group comparsion, only the growth hormone levels in the two training groups were significantly increased (P=0.001) and (P=0.026) respectively in group with and without blood flow restriction compared to the control group (P=0.001).
conclusion: The results suggest that the pattern of growth hormone and lactate changes in both training groups are similar to each other. It seems that low intensity resistance training with blood flow restriction can be an alternative to traditional high-intensity training in those who do not have the ability to lift heavy weights or during rehabilitation.
