The aim of present study was to investigate the effect of 10-week aerobic training and unsaturated-high-fat-diet on adiponectin serum in obese male rats. Blood samples were collected of forty-eight wistar male rats (average weight 195±5g, age 8 weeks) at 1st, 18th and 28th weeks after overnight fasting. After first sampling, remaining 40 rats were randomly divided into control (n=16) and high-fat-diet (39% of energy content from unsaturated-fat) (n=24). High-fat-diet group randomly divided in to exercise training and high-fat-diet subgroups after 18 weeks. Exercise training group ran for 10 weeks (5d/wk) with intensity equivalent to 70 to 75% of vo2max. Serum levels of total and HMW adiponectin as well as lipid profile and glycemic variables were measured. The results of this study indicate that in comparison to unsaturated-high-fat-diet, aerobic training in unsaturated-high-fat-diet induced obese male rats, increased serum concentration of total adiponectin significantly (P> 0/01). Also insulin resistance index and serum concentrations of insulin, glucose, total cholesterol, LDL-C and TG were decreased in aerobic exercise compare to high-fat-diet group (P> 0/05). This study indicates that aerobic training increase serum concentrations of total adiponectin in obese male rats even with simultaneous consumption of unsaturated-high-fat-diet and cause improvement in lipid and metabolic profiles.
