Background The temporal and insular cortex (TC, IC) have been associated with autonomic nervous system (ANS) control the awareness of emotional feelings from body. Evidence shows that ANS rating perceived exertion (RPE) regulate exercise performance. Non-invasive brain stimulation can modulate cortical area directly beneath electrode related to RPE, but it could also affect subcortical areas by connection within cortico-cortical neural networks. This study evaluated effects transcranial...
To investigate whether the manipulation of brain excitability by transcranial direct current stimulation (tDCS) modulates heart rate variability (HRV), effect tDCS applied at rest on left temporal lobe in athletes (AG) and non-athletes (NAG) was evaluated. The HRV parameters (natural logarithms LF, HF, LF/HF) assessed 20 healthy men before, immediately after sham stimulation. After anodal AG parasympathetic activity (HFlog) increased (P < 0.01) sympathetic (LFlog) sympatho-vagal balance...

Post-stroke patients usually exhibit reduced peak muscular torque (PT) and/or force steadiness during submaximal exercise. Brain stimulation techniques have been proposed to improve neural plasticity and help restore motor performance in post-stroke patients. The present study compared the effects of bihemispheric cortex transcranial direct current (tDCS) on PT maximal resistance exercise performed by vs. healthy controls. A double-blind randomized crossover controlled trial (identification...

The study evaluated the effect of transcranial direct current stimulation (tDCS) applied over prefrontal cortex on oxygen uptake (V˙ O2) at rest and during post-exercise recovery. V˙ O2 was assessed in eleven healthy subjects before, tDCS (sham or anodal tDCS, 2 mA, 20 min), 30-min following isocaloric aerobic exercise (~200 kcal). During no changes were observed compared to baseline (P=0.95) sham condition (P=0.85). association between increased throughout recovery (P<0.001). Therefore,...
The main purpose of this study was to investigate the level agreement between gas exchange threshold (GET) and heart rate variability (HRVT) during maximal cardiopulmonary exercise testing (CPET) using three different modalities. A further aim establish whether there a 1:1 relationship percentage reserve (%HRR) oxygen uptake (%V˙O2R) at intensities corresponding GET HRVT. Sixteen apparently healthy men 17 28 years age performed CPETs (cycling, walking, running). Mean V˙O2 HRVT were 16 bpm...

This study compared resting oxygen uptake (V̇O 2 ) with the standard metabolic equivalent (MET) value of 3.5 mL·kg −1 ·min , tested accuracy a previously published prediction model for V̇O and proposed new more homogeneous population. One hundred twenty-five apparently healthy men, aged 17–38 years, visited laboratory assessment . The mean 3.21 (95% confidence interval (CI), 3.13 to 3.30) was significantly lower than MET (mean difference, 0.29; 95% CI, 0.20 0.37; t = 6.7; p < 0.001). by...
