Adiponectin and insulin resistance index response to six weeks of resistance training with different exercise order in overweight women

Background: The aim of present study was to investigate the effects of six weeks resistance training with different order on serum adiponectin and insulin resistance index in overweight women.

Methods: 31 overweight women with average age of 22/35 ± 2/35 years and with BMI= 27/74 ± 2/47 kg/m2 were selected and randomly divided into three groups: the experimental group 1 (N = 10), the experimental group 2 (N = 11) and the control group (N = 10). The experimental group one performed exercises from large to small muscles and experimental group two, performed exercises from small to large muscles. The training program was performed three times a week and each session included three sets with 12 repetitions and intensity of 50-60% 1RM. The rest time between the stations was three minutes and the rest time between each set was two minutes. The control group did not have activity during these six weeks. Blood sampling was performed in two stages 24 hours before the start of the protocol and again 20 hours after the completion of the course, with completely similar conditions and followed by 12-14 hours of fasting.

Results: By using repeated ANOVA, results showed that adiponectin did not change significantly in any of the experimental groups (p =0/99). Insulin resistance index decreased significantly in two experimental groups and the type of resistance training did not effect this index (P=0/15).

Conclusion: Resistance training program and so changing the sequence of performance of resistance exercise – none of them – do not have any effect on adiponectin and insulin resistance index.
