Comparison of Metabolic Some Hormones Response to Resistance Training with Different Intensity with and without Blood Flow Restriction in Active Girls

The purpose of this study was to compare metabolic hormone responses to resistance exercise with alternative levels and with and without blood flow restriction in active girls. The research methodology was semi-experimental with cross design, 11student from the university of Esfahan (19 years old) were chosen and were posited in 3 different exercise conditions: low intensity resistance training with blood flow restriction, the same condition without blood flow restriction and high intensity resistance training without blood flow restriction, all of the training was conducted within a week interval. Practice sessions include flexion and extension for arm and knee in 3 periods with 15 repetitions. In blood flow restriction group, while training, the proximal of the intended organ with tourniquet (100-120 mmhg) was closing. The blood sample, before and immediately after extreme training was collected in order to determining the growth hormone density, Insulin-like growth factor, Testosterone, Cortisol and lactate. The repeated measure analyze of variance was used to analyze data. According to results the growth hormone and lactate in all three training conditions had a significant increase in comparison to pre-test (P
