Abstract

Background: Multiple sclerosis is a chronic disease of the central nervous system which leads to myelin destruction. The aim of this study was to examine the effect of aerobic training on functional capacity and percent body fat in women with moderate multiple sclerosis.

Materials and Methods: In this clinical trial, 15 women with multiple sclerosis (aged 33.68±8.22 years) with EDSS<4 were randomly divided into experimental (n=8) and control (n=7) groups. An aerobic program prolonged for 8 weeks, 3 days/week, 20-40 minutes/day, with 60-80% of HRmax was run in the experimental group. Some functional capacities, such as speed running, walking endurance, balance, and VO2 Max, as well as BF% were measured before and after the training program in both groups.

Results: The results showed that aerobic training led to significant increases in walking endurance, walking speed, balance, and VO2max (p<0.001). These indices, however, decreased significantly in the control group (p<0.05). Additionally, after the training program, percent body fat decreased significantly in the experimental group (p=0.005), but it increased significantly in control group (p=0.002).

Conclusion: Considering the findings of this study, it can be stated that aerobic training can improve functional capacity and decrease percent body fat in multiple sclerosis patients

Abstract

Introduction: Considering the synthesis and release of myokines from muscle tissue during exercise and the relationship of myokines with the development of strength and increase in muscle volume, the purpose of this study is to investigate 12 weeks of resistance training on the serum levels of myonectin and FGF- There were 21 middle-aged men.
Methods: In a semi-experimental study, 40 middle-aged men of Arak city (mean age 38.27 ± 6.02 years, weight 77.12 ± 11.23 kg, height 174.05 ± 7.22 cm) were selected and randomly placed in two resistance training groups (20 people) and control (20 people). The training group performed 12 weeks of resistance training 3 times a week with an intensity of 65-80% of maximum strength. Blood was taken from all the subjects 48 hours before and after the intervention, and serum levels of myonectin and FGF-21 were checked by the ELISA method. After checking the normality of the data, they were analyzed by the correlation t-test and independent t-test at a significance level of less than 0.05.
Results: Resistance training caused a significant increase in the serum level of myonectin (P = 0.001) and the serum level of FGF-21 (P = 0.001) and also decreased the percentage of fat (P = 0.417) in middle-aged men.
Conclusions: According to the results of this study, it seems that resistance training can have positive adaptation by increasing the serum levels of myonectin and FGF-21 in the regulation of muscle mass, hypertrophy process, angiogenesis process, and Improve the body's metabolism.
