Comparison of an acute bout of concurrent exercise training in different intensities on tumor necrosis factor- α (TNFα) and interlokin-6 (IL-6) in active men

The aim of this study was to investigate the comparison of an acute bout of combined exercise training in different intensities on interlokin-6 and tumor necrosis factor-α in active men. Ten active men with mean age 20.3±1.15 years, body mass index 21.88±1.73 kg/m2, and Vo2max 48.93±3.03 ml/kg/min volunteered for this study. Participants performed combined (at first aerobic phase and then resistance phase) exercise in low, moderate, and high intensities while aerobic phase including of 300 kcal in 8, 9.6, and 11.2 km/hr and resistance phase was composed of 45, 65, and 85% of 1- repetition maximum in 6 movements. Blood samples were taken before, immediately after and 24 hours after exercise. There was no significant difference in main effect of sampling time (P>0.05), exercise intensity (P>0.05), and interaction effect of time×intensity (P>0.05) in interlokin-6, tumor necrosis factor-α, and glucose. The results of this study indicated that an acute bout of combined exercise does not affect interlokin-6 and tumor necrosis factor-α level in active men while energy expenditure during aerobic phase and workload during resistance phase is similar in different intensities.
