Abstract
Blood flow restricted training useful and effective training exercises for increased is athletes performance level.The aim of this study was to evaluate the effect of acute on a treadmill training with BFR on serum levels of growth hormone (GH), insulin like growth factor 1 (IGF-1) and cortisol in inactive girls student.Thirty healthy girls student with an age range of 19-24 years who volunteered to participate in the study were selected as samples and randomly divided into three groups: 1) training on a treadmill BFR (intensity: 2 miles/hour, 5 sets of 2 minutes with one minute of rest in between each set), 2) training on a treadmill without BFR (with the samevolume of BFR) and 3) control (BFR and without exercise). The level of hormones in fasting was measured before and immediately after exercise. At The end of the study, data were analyzed with one-way ANOVA and Tukey test and for to compare the differences before and after the exercise of the Paired-Samples t test was used in the level of p< 0.05. Data were analyzed showed serum GH, IGF-1 and cortisol levels significantly increased in post exercise in BFR group compared to pre-exercise (P<0.05). The results of one-way ANOVA showed Between Average serum GH , IGF-1 and cortisol levels Three groups after exercise a significant difference (P<0.05).In conclusion, acute walking on a treadmill with BFR could increases in anabolic and catabolic hormones in inactive young girls. So in terms of practical, seem limited blood flow in the training on a treadmill is an important factor in the creation of acute hormonal responses and there are executive limitations lower compared with high-intensity resistance training and realization the expected goals of the high-intensity training and is applicable for wider range of people, including inactived individuals, disabled, sick and elderly.
