|Title:||Immune responses to an upper body tri-set resistance training session|
|Abstract:||The purpose of this study was to evaluate the acute immune responses to an upper body tri-set resistance training (RT) session in RT trained individuals. Eighteen young trained men (220 +/- 18years) were randomly assigned to an exercise group (EG; n=9) or control group (CG; n=9). The EG completed an acute tri-set RT protocol using two combinations of three exercises for the same muscle group with six to eight repetitions at 75% of one repetition maximum (1RM) for each exercise. Blood samples were collected before (Pre), and 15min (Post) and 24h (P24h) after the acute RT protocol to determine basal and acute total leucocytes and leucocyte subsets counting, interleukin-6 (IL-6), tumour necrosis factor- (TNF-) and cortisol. There were significant increases in total leucocytes, monocytes and neutrophils at Post as compared with Pre (P<005). Additionally, total leucocytes and monocytes were reduced even at P24h when compared to Pre (P<005). There were no significant changes in plasma concentrations of TNF-, IL-6 and cortisol throughout the measured moments. As compared to CG, EG demonstrated very large effect sizes for total leucocytes, neutrophils and monocytes 15min postprotocol and a reduction (trivial and small effect sizes) P24h. These results suggest that the tri-set RT session did not exacerbate the acute inflammatory response and might be a good option for variations in RT methods for trained individuals.|
