Comparison of the effect of 8 weeks endurance, resistance and concurrent training on irisin, some glycemic indexes and the visceral fat to muscle mass ratio on sedentary obese women

Protocol summary

Study aim
The purpose of this study was to compare the effects of 8 weeks endurance, resistance and concurrent training on irisin, some glycemic indexes and visceral fatty acids ratios on the muscular mass of obese Inactive women.
Design
In this study, 33 obese women,chosen according to inclusion criteria, were randomly divided into three homogeneous groups including endurance training, resistance training, and concurrent training through random number table.
Settings and conduct
The subjects do exercise with 50 to 70% VO2max for the endurance group and 60 to 80% of 1RM for the resistance group and the combination of both for concurrent group. The exercise will be done through 40-45 minute sessions in the gym, 3 sessions per week for 8 weeks.
Participants/Inclusion and exclusion criteria
All participants are non-active and obese women who participate after getting informed consent. They do not have a sports ban, no specific disease, not using a particular drug, and they must complete the training program.
Intervention groups
Interventions include endurance training, resistance training and concurrent training in three separate groups.
Main outcome variables
Before and after the training period, physical fitness indicators such as maximum oxygen consumption, body composition (BMI), fat percentage and visceral fat to muscle mass ratio are measured and blood profiles such as serum irisin, fasting glucose, insulin and insulin resistance is evaluated.
