The aim of this work was to study the behavior of untrained and trained subjects when submitted to a condition of development of maximum force. We analyzed the creatine kinase (CK) enzyme plasma concentration which, in accordance with scientific literature, can be an interesting marker of muscle cell alterations. Two groups constituted the subjects of this study: the nontrained group, which executed sessions of exhaustive plyometrics exercises, and the trained group, which had and increase in loads of weight exercises during a shock microcycle. The analyses of the CK plasma showed that the nontrained group had a peak of CK plasma 48 hours after the exercise(p<0.001), whereas the trained group did not suffer significant alteration (p>0.05) from this same parameter with increase of load in shock microcycle. These results suggest that there is a threshold of maintenance of the cell microinjury, which must be respected when the aim is to reach positive adaptations at long term. |
