Background and Aim: Resistin is an adipose tissue derived adipokines that play important role in obesity and insulin resistance. The aim of present study was to investigate the effects of 8 weeks resistance training with two different intensities on serum levels of resistin and insulin resistance in obese elderly women. Materials and Methods: Thirty obese elderly women (mean age of 64.5±3.64 years and body mass index of 31.8±1.02 kg/m2) randomly divided into 3 groups including control, low intensity resistance training (LIRT), and high intensity resistance training (HIRT) groups and each group consisted of 10 subjects. The HIRT (80% of one repetition maximum) and LIRT (30% of one repetition maximum) performed for 8 weeks, 3 sessions per week while control group did not participate in any training program. Blood sampling collected in both pre and post-test stages and then resistin levels and insulin resistance were measured. The data analyzed by analysis of covariance and Tukey post hoc tests at the significant level of p < 0.05. Results: Rresistin levels between different groups were not significant (p=0.29); however, decreased insulin resistnace and body fat percent were observed in the LIRT and HIRT groups compared to control group (p=0.001). Conclusion: Resistance training with low and high intensity independent of changes at the resistin levels is accompanied by the favorable changes in the metabolic condition in obese elderly women.
