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.

Background and Aim: Despite the investigation on anti-inflammatory effects of exercise training, the simultaneous effect of exercise training and Zataria Multiflora supplement on inflammatory factors is unclear. Therefore, the aim of this study was to identify the effects of 8 weeks of combined exercise training along with Zataria Multiflora supplement ingestion on serum levels of monocyte chmoattractant Protein-1 (MCP-1) and insulin resistance in overweight men. Materials and Methods: Forty overweight men with average age of 29.35±2.99 years and body mass index 27.66±1.2 kg/m2 assigned into 4 equal groups including placebo, Zataria Multiflora, training and training+Zataria Multiflora groups. Combined training program (resistance-aerobic) performed for 8 weeks/ in 3 sessions per week. Resistance training program consist of 6 exercises up to 75-80 percent of one-repetition maximum. Moreover, aerobic training program consists of 10-20 minutes running up to 70-75 percent of maximum heart rate. Moreover, Zataria Multiflora and training+Zataria Multiflora groups ingested daily 500 mg Zataria Multiflora capsule. MCP-1 and insulin levels measured by Elisa method and data were analyzed by repeated measures analysis of variance test and Bonferroni post hoc test at significance level of pResults: Both MCP-1 and insulin resistance variables significantly decreased in both training (p < 0.001) and training+ Zataria Multiflora (p < 0.001) groups, while this variation was greater in training+Zataria Multiflora group (p < 0.05). In addition, only insulin resistance significantly decreased in Zataria Multiflora group compared to placebo group (p < 0.001). Conclusion: It seems that exercise training (consist of resistance and aerobic training) with combination of Zataria Multiflora have a positive synergic effect for overweight subjects that it caused by modulating of the inflammatory markers such as MCP-1 and reduction of insulin resistance.
