Investigating the changes of some growth factors following eight weeks of combined exercises with and without blood flow restriction in young women
The aim of this research was to investigate the changes of some growth factors following twelve weeks of combined exercises with and without blood flow restriction in young women.
The statistical population of this research was the inactive young women of Mashhad. Among them, 45 people were randomly divided into three groups of combined exercise + with blood flow restriction (15 people), combined exercise group + without blood flow restriction (15 people) and control group (15 people). The current research methodology was semi-experimental with a pre-test-post-test design. The combined training group did three resistance and aerobic training sessions per week. These exercises were done on consecutive days. The combined training group with blood flow restriction performed resistance training by closing the cuff and training intensity 20% of one maximum repetition at the beginning of the training and aerobic exercise with 45% maximum heart rate, and the combined training group without blood flow restriction, only resistance training with 80% 1RM and training They did aerobic exercise with 45% HRmax. The data were analyzed using t-correlated test, one-way analysis of variance test and Bonferroni's post hoc test at a significance level of P≥0.05 and SPSS software version 21.
Statistical results show that twelve weeks of combined exercises with blood flow restriction and without blood flow restriction increases the levels of insulin-like factor 1, follistatin, platelet-derived factor and decreases myostatin in young women.
combined exercises with blood flow restriction can improve the physical condition and improve the physiological conditions of young women by making some changes affecting the growth factors.
