The purpose of this study was to investigate the effects of a single session of resistance training on adiponectin levels and insulin resistance until 24 hours post-exercise. Materials and Methods: This experimental study, which followed a pretest-posttest design, was conducted on a group of 10 healthy male volunteers (23±1.4 years) with no history of participation in any regular exercise programs, weight changes more than 2 kg, special diseases, and smoking over the past 6 months that had normal body mass index (BMI) (23.7±1.6 kg.m-2). The subjects performed a single session resistance training (3 sets of 10 repetitions at 75% of 1 repetition maximum). Adiponectin, glucose, insulin, and insulin resistance index levels were measured before and 24 hours after the exercise. Results: There were no significant differences for adiponectin (μ g.ml-1) pre- (6.98±1.9) and post-exercise (8.07±1.4) and glucose (mg.dl-1) pre- (81.3±7.6) and post-exercise (80.7±6.4). However, insulin resistance index pre- (1.34±0.27) and post-exercise (1.06±0.11) and insulin concentration (UΙμ.ml-1) pre-(6.64±0.88) and post-exercise (5.37±0.43) decreased significantly 24 hours post-exercise (P LA eng UL http://jams.arakmu.ac.ir/article-1-921-en.html M3 ER -
