The purpose of present study was to investigate the impacts of endurance, resistance and concurrent training on adiponectin resting levels of sedentary men.

Forty-four sedentary students were randomly assigned to one of four groups: endurance training (ET; 22 ± 0.89 yr, n=12), resistance training (RT, 21 ± 1.57 yr, n=9), concurrent training (CT, 21.38 ± 2.6 yr, n=14) and control group (CG, n=10).

After primary measurements, blood samples were drawn with subjects in fasting and resting state for determination of the basic level of adiponectin. The subjects participated in E, R and C training for 8 weeks. The ET group ran 3d/w at 65–85 % of maximum heart rate. The exercise training session for the RT group consisted of 3 sets of 10–15 repetitions of weight training exercise that increase progressively, and repeated 3 sessions per week. The CT group trained exactly the sum of ET and RT groups. Correlated samples t-test and ANOVA were used. The results of the present study showed that after the eight-week training, the adiponectin levels of subjects increased in 3 groups of training but this increase was not significant. The level of adiponectin in CT group increased more than in ET and RT groups. Also, there were no significant differences in content of adiponectin among groups.
In general, slight increases in adiponectin levels in training groups especially in CT group may indicate the most potential of CT group in increasing the levels of adiponectin in sedentary men. However more researches are needed to identify the effects of concurrent training
(Tab. 4, Ref. 27).
