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.

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.

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).

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.

Exercise can lead to various hematological changes and it may be effects on some blood variables. The purpose of present study was to investigate the effects of resistance training with different order on hematological changes (include HGB, HCT, RBC, WBC, MCV, MCH, MCHC, RDW, PLT and MPV) in overweight women (BMI= 25-30 Kg/m2).

Thirty-one overweight students (Weight: 71.91 ± 8.28 kg and Height: 160 ± 0.05 cm) were objectively selected and randomly divided into three groups: the experimental group 1 (perform exercises from large to small muscles, n= 10), the experimental group 2 (perform exercises from small to large muscles, n= 11) and the control group (without any training program, n= 10). Resistance training consists of 6 weeks (3 sessions per week). The hematological variables were measured in resting conditions before experiment and again after completion of the training period.

Findings using by one-way ANOVA revealed there were no significant differences in any of the hematologic variables levels between three groups.

In general, results showed that medium-term resistance training program and so changing the sequence of performance of resistance exercise – none of them – do not have any effect on hematologic responses.
