Background Objectives: The aim of the present study was to investigate the possible effect of 8-week aerobic exercise on undercarboxylated osteocalcin and hs-CRP and insulin resistance in overweight women. Materials & Methods: 20 overweight women (weight 73.19 ± 2.28 kg, age 39.38 ± 3.66 years old, height 1.61 ± 0.04 cm, and body mass index(BMI) 28.19 ± 4.36 kg/m2) were randomly selected and divided into control and experimental groups. Blood samples from participants were taken 48 hours before pre-test and also after 8 weeks of training. Aerobic exercise was done within 8 weeks – 3 sessions per week with the intensity of 65-70% of reserve heart rate. Data analysis for intragroup and intergroup differences was done using dependent and independent t-test, respectively. A significant difference was observed at pResults: The study yielded that the level of undercarboxylated osteocalcin in experimental group significantly increased (p=0.01) in comparison to that of control group. It was also revealed that, in comparison with control group, the level of hs-CRP (p=0.083) and insulin resistance (p=0.158) in experimental group insignificantly decreased after 8-week training. Conclusions: The eight weeks of regular exercise showed significant increase in undercarboxylated osteocalcin that, with possible impact on beta cells, can be cause improvement in effective factors of resistance insulin such as increased insulin secretion and decreased glucose levels.
