The Effect of Three Types of Training (Endurance, Resistence and Combined) on Rest Levels of Adiponectin in Overweight Non - Athlete Men

The purpose of the study was to investigate the impacts of endurance, resistance and concurrent training on adiponectin resting levels of non-athlete men. Forty four obese non-athlete students (BMI > 25) voluntary participated in this study and were randomly based on BMI assigned to one of four groups: endurance training (ET, 22 ± 0/89 years, height 174/64 ± 4/72 cm, weight 90/55 ± 10/80 kg, N = 12); resistance training (RT, 21 ± 1/57 years, height 171/11 ± 5/51 cm, weight 92/22 ± 15/85 kg, N = 9); concurrent training (CT, 21/38 ± 2/06 years, height 173/65 ± 7/07 cm, weight 86/61 ± 15/05 kg, N = 13); and control group (CG, 21/44 ± 1/13 years, height 175/61 ± 5/09 cm, weight 90/00 ± 14/05 kg, N = 9). After primary measurement and 48 hours after the last training session blood samples were drawn with the subjects in the 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 25 – 40 minutes a day ansd 3 days per week at 65 - 85% maximum heart rate. The exercise training session for the RT group consisted of three sets of 10 – 15 repetitions of weight training exercises of primary muscles group that increased progressively and repeated three sessions per week (including: chest press, squat, opening leg, knee flexion and extension, chest dumbbell press, leg press, seated rowing, and standing rowing). The CT group exactly trained the sum of the ET and RT groups. Correlated samples t-test and one way analysis of variation were used to compare within and between groups differences respectively. The result of the present study showed that after 8 weeks training the diponectin levels of subjects increased in three groups of training but this increase was not significant. The level of adiponectin in CT group increased more than ET and RT groups. Also, there were no significant differences in content of adiponectin among groups. In general, slightly increases in adiponectin levels in training groups, especially CT group may indicate the most potential of CT group in increasing the levels of adiponectin in non-trained men. However there are need more related researches to indentify the effect of concurrent training.
