O exercício físico induz recuperação funcional pós-trauma do nervo ciático em ratos

Abstract

Recent studies show a probable relationship between physical training and functional recovery after a peripheral nerve lesion. Meanwhile, there is not an agreement about what kind of physical training should be elected to obtain best results. The present research verifies influence of predominant aerobic and anaerobic physical exercises on functional recovery process on 5º, 10º, 15º and 20º days after rat s sciatic nerve crush, by a non-invasive method called sciatic static index. Statistical analysis was made with 0,05 significance level. With variance analysis application it was observed a increment on function al recovery by the tests accomplished in 15º and 20º days after lesion to groups submitted to physical exercises. Latterly, it was employed Turkey test, which made possible to conclude that predominant aerobic and anaerobic exercises are not different on benefits offered in functional recovery process after peripheral nerve lesion. Finally, two-way variance analysis demonstrated that don t influence in a significant manner the functional recovery process to analyzed groups, evidencing that physical exercises increase recuperation of nerve function.
