Abstract
Background and Aim: The inflammatory markers cause changes in body composition and edocrine activity and lead to cardiovascular disease and diabetes on the other hand, active lifestyle and physical activity may improve these indicators. The aim of the present study was to determine the effect of 8 weeks combined resistance and endurance training at morning and evening on Interlukin-6 (IL-6) and C-reactive protein (CRP) in overweight men. Materials and Methods: 40 non- athletes overweight men (age mean 24±1.57 and BMI mean 28.22±3.6) were randomly allocated to two groups morning and evening combined training and two groups morning and evening control. Morning and evening training groups performed the combined training protocol three sessions per week for 8 weeks. The combined training program included a strength and endurance training that subjects first implemented a strength and then endurance program at their practice sessions. While the control groups were denied doing training programs during the research period. Blood samples (5 cc) were taken from the participants at the beginning of the period and end of week 8 in order to measure CRP, IL-6. Within-group differences were analyzed by paired samples t-test and the between-group differences were analyzed by one-way ANOVA (p<0.05). Results: The results showed 8 weeks of combined training in the morning and evening decreased CRP and IL-6 in the experimental groups compared with the control groups. Conclusion: According to results of this study, combined training in the morning and evening reduces the percentage of pre-inflammatory factors, although there was no significant difference between these indices in the morning and in the evening, Therefore, overweight men can be advised to take advantage of a strength-endurance training program regardless of training time to reduce cardiovascular risk factors.
