Other: transcutaneous electrical nerve stimulation
Application of low frequency (10-Hz) and high frequency (100-Hz) TENS, in two different days
- differences in blood levels of catecholamines differences in blood levels of catecholamines differences in blood levels of catecholamines Differences in blood levels of catecholamines [ Time Frame: one minute before and after transutaneous electrical nerve stimulation intervention (acute effect) ]For evaluation of catecholamines (epinephrine, norepinephrine and dopamine) will be held one antecubital venipuncture and collected into tubes containing ethylenediaminetetraacetic acid (EDTA).
- improvement of heart rate variability [ Time Frame: one minute before and after transcutaneous electrical nerve stimulation intervention (acute effect) ]Temporal series of the tachogram, related to each selected segment were evaluated quantitatively considering the values of HR, total and normalized powers of low frequency (LF - 0.04 to 0.15 Hz) and high frequency (HF - 0.15 to 0.40 Hz) components of HRV and the sympato-vagal index (LF/HF).
