The exercise can elicit benefits or damage on the immunologic system responses, depending the variables intensity or volume which must be considered. In other hand, the protocols of resistance exercise have showed effectives to improve alterations in the body composition. Thus, it is very important evaluate protocols of resistance exercise that can increase the muscle mass with a decrease in fat mass without development a inflammatory state, specially if the subjects are not athletes. In this work, we have studied the effects from a protocol of exercise resistance in circuit on women, 39.71 ± 3.8 years old (Media ± Standard Error). The protocol was development with intensity and a volume sufficient to elicit alterations in body composition without important inflammatory responses even after acute sessions of effort or any cumulative effect during the all period of training. Thus, the protocol consisted of 3 week sessions of circuit training of 9 stations with alternate recruitment of different muscle groups during 10 weeks. The subjects had to perform 2 times the circuit in each session of training. Each station was realized one set of 8-12 maximal repetitions (RM) for time. The body composition was analyzed by DXA and the inflammatory effects by cytokines (IL1-beta; IL-6; IL-8; IL10, IL-12p70 e TNF) changes in serum. The blood samples were collected from the anticubital vein before the sessions of training; 5 min, 24h and 48h pos second session training; and 5 min, 24h, 48h and 96h pos the last session of period of training. The statistical data were analyzed by test t Student application in normal distribution and Wilcoxon test in not normal distribution. The samples of cytokines were compared by the Friedman test with Tuckey test pos hoc (α=0,05). The results showed a significant increased in the muscle mass and decrease in the fat mass. The serum concentrations of cytokines no showed alterations during all the experimental period, indicating any inflammatory effects from the protocol adopted.
