Effect of Eight Weeks of Resistance Training with Limitation of Blood Flowing on Insulin-1 Factor, Agerin C Cerpinal Perpetrate and Elderly Composition

Changes in old age cause some problems in the elderly that these changes can be anatomical or physiological. The aim of the present study was to evaluate the effect of eight weeks of resistance training without blood flow on insulin-like factor (IGF-1), C-terminal agrin fragment peptide (CAF) and body composition of the elderly.

The present research method is quasi-experimental and pre-test-post-test design. The statistical population in this study is the men of Mashhad. According to the inclusion criteria, after initial screening by the researcher, 45 people were randomly selected.), Weight 81.34 ±5.99 (kg), body mass index 27.03 ± 1.51, experimental mass 26.26 ± 2.26 (percent) and muscle mass 53.36 ±4.07 in three groups Resistance training with (15 people) and without (15 people) restriction of blood flow و and control group (15 people) were divided. Data were analyzed using one-way analysis of variance and Tukey test at the significance level of P /0.05 and SPSS software version 21.

The results of the present study showed that the serum level of IGF-1 had a significant increase between the groups of resistance training with and without restriction of blood flow compared to the control group (P = 0.001, F = 49.02). Also, resistance training with limited blood flow had a greater effect on increasing IGF-1 levels (ES = 352.14, PC = 22.61) than the resistance training group without blood flow restriction (ES = 200, PC = 1.31). The results also showed that there was a significant decrease in serum C-peptide level between resistance training groups with limited blood flow and control group (P = 0.001, F = 39.93) but there was no significant difference between experimental groups (493 / 0 = F, 09/0 = P). The results also showed that exercise with and without restriction of blood flow reduced fat mass (P = 0.001, F = 16.95) and body mass index (P = 0.001, F = 44.30) compared to the control group. But there was no difference between the experimental groups (P = 1.00, F = 0.46).

Resistance training without blood flow restriction increases IGF-1 and decreases CAF peptide, fat mass and body mass index in the elderly
