Sedentary lifestyle means that the lack of physical activity and increased caloric intake, leads to the accumulation of body fat and metabolic disorders including type-2 diabetes, hypertension and cardiovascular disease. The purpose of present study was the comparison of upper body, lower body and concurrent training on the levels of glucose, insulin and insulin resistance index among untrained academic women. 56 sedentary women (aged: 21+ 3 yr, Body Mass Index: 21.5+ 3.5 kg/m2, N=14) were randomly assigned to one of four groups (upper body training, lower body training, concurrent training and control group). Three sessions in a week training groups performed a 6 resistance movements for the upper body, lower body and concurrent trainings. After 4 and 8 weeks, blood samples were taken in order to measure glucose, insulin and insulin resistance index. Results of the present study showed that glucose levels had a significant reduction in the measured times. Also, insulin levels had a significant decrease in the measured times and there was a significant reduction of insulin levels among groups. The insulin resistance index changes had a significant reduction in the measured times. Although an upper body (20%) and lower body (21%) and concurrent (19%) resistance training caused an increase in and improving strength (1RM) and performance, it seems that different types of resistance training applied in this study caused a significant decrease in the levels of glucose, insulin and insulin resistance index among training groups compared to the control group.
