Background: Smoking can decrease adiponectin serum and increase insulin resistance index. The purpose of present study was to examine the effect of one session of exhaustive aerobic exercise on levels of adiponectin serum and insulin resistance index in smoker men.
Materials and methods: A semi-experimental design was used. The target population consisted of smoker students of the Hakim Sabzevari University, from whom twelve smoker male students volunteered and were randomly divided into three situations; control, exhaustive aerobic exercise at 70-75% intensity of maximal heart rate, and exhaustive aerobic exercise at 90-95% intensity of maximal heart rate, in a crossover design.Two situations of aerobic exhaustive exercise programs involved running on treadmill with intensities of 70-75% and 90-95% of maximum heart rate of the subjects. During this period, the control group did not perform any physical activity. To calculate changes in plasma volume and measurement of adiponectin, glucose, insulin and lipid profile indices blood samples were collected before and immediately after performing of aerobic exercises. Data were analyzed using one way analysis of variance (ANOVA).
Results: After the correction of results with respect to plasma volume changes, no significant differences in serum of adiponectin levels (P=0.825) and insulin resistance index (P=0.756) were determined between the control and experimental situations. Furthermore, no significant difference was observed among the three situations in the glucose (P=0.633), insulin (P=0.768), low density lipoprotein (P=0.075), high density lipoprotein (P=0.131), total cholesterol (P=0.559), and serum triglyceride (P=0.641).
Conclusion: One session of exhaustive aerobic exercise with two different intensities has no effect on levels of serum adiponectin and insulin resistance index in smoker men. However, to achieve more conclusive results, further investigation is warranted.
