Comparison of the effect of one session of resistance training with and without blood-flow restriction of arm on changes in serum levels of growth hormone and lactate in athlete females
Background:¬ Exercise trainings with blood-flow restriction have been effective in improving various physical factors and can be a unique and beneficial method in the field of medicine. Therefore, the current study aimed to compare the effects of one session of resistance training with and without...

Iran.Background:¬ Exercise trainings with blood-flow restriction have been effective in improving various physical factors and can be a unique and beneficial method in the field of medicine. Therefore, the current study aimed to compare the effects of one session of resistance training with and without blood-flow restriction of arm on changes in serum levels of growth hormone and lactate in athlete females. Materials and Methods: To perform the current clinical trial, 30 basketball players aged 23-30 years were randomly divided into three groups: traditional resistance training (intensity of 80% 1RM), resistance training with blood-flow restriction (intensity of 30% 1RM) and control group. Training started with one set of 30 repetitions and ended with two sets up to fatigue with the rest time of 30 seconds. Blood samples were taken before and immediately after completing exercise training. Results: Post-test findings indicated a significant increase in the serum levels of growth hormone in two training groups compared to pre-test, but the amount of lactate ion in all three groups significantly reduced compared to the pre-test (P<0.05). Also, growth hormone levels in groups with and without blood-flow restriction increased significantly compared to the control group (P=0.001 and P=0.026, respectively). conclusion: The pattern of growth hormone and lactate changes in both groups, with and without blood-flow restriction are similar to each other. It seems that for those who are not able to lift heavy weight, low intensity resistance training with blood-flow restriction can be replaced with traditional high-intensity training.http://feyz.kaums.ac.ir/article-1-3493-en.htmlResistance trainingAthlete femalesBlood-flow restrictionLactateGrowth hormone |
