Melhoria da recuperação do músculo tibial anterior através da Sequência Intermitente da Compressão Pneumática nas Pernas.

In this study we examined the effect of Intermittent Sequential Pneumatic Compression (ISPC) of the legs on the recovery of fatigued Tibialis Anterior (TA) muscles. Eight sub- jects performed 10 min fast walking on a treadmill, followed by 2 min sustained effort of the TA (load A). Immediately afterwards they took 3 min of resting time, during which one leg was treated by ISPC (active recovery) and the opposite one served as a control (passive recovery). A second sustained effort (load B), similar to load A in intensity and duration, followed the recovery period. Surface EMG of the TA was used to monitor muscle fatigue. The results indicate that the mean power frequency (MPF) of the actively recovering TA was significantly higher than that of the passively recovering TA, irrespective of the side on which ISPC was applied. An additional interesting result was the higher MPF in the begin- ning of load B compared to that of the end of load A. However, this difference was signifi- cant in the actively recovering leg, but not so in the passively recovering leg. It was conclu- ded that ISPC treatment of fatigued muscle after a sustained effort improves its contractile capacity in comparison to passive recovery.

Key words: fatigue, intermittent sequential pneumatic compression, mean power fre- quency, recovery, water evacuation.
