Introduction and Aims
In aging, the size and strength of skeletal muscle are reduced. Therefore, research on potential interventions that can reduce the loss of function is very important. Therefore, the purpose of this study was to investigate the effect of eight weeks of combined exercise with and without blood flow restriction on serum levels of myostatin, folinolatin and IGF-1 in elderly women.
Materials and Methods
40 older women with ranging from 55-70 years were randomly divided into four groups, 1) combined exercises with blood flow restriction, 2) low intensity exercise without blood flow restriction, 3) combined exercise with High intensity without blood flow restriction, and 4) control group. The Training program included resistance and aerobic training in eight weeks (three sessions per week). Serum levels of myostatin, follistatin and IGF-1 were measured before and after the training period. One-way repeated-measures ANOVA were used to assess the effect of training protocols. The significance level was set at P <0.05.
Results
There was a significant difference between groups in serum folinatein and myostatin levels (p = 0.0001), Although, there was a significant increase in pre-post test level of IGF-1, there was no significant change in the level of IGF-1between groups (p>0.05).
Conclusion
According to the results of this study, it,s seems that the use of combined exercise with vascular occlusion in elderly women leads to positive effects of anabolic agents in preventing muscle atrophy and it is recommended that they be included in the training program for elderly women
Keywords: combined exercise training, vascular occlusion, indices of muscle growth factors, elderly women
