      Background/aims: Altered autonomic nervous system activity has been reported in patients with overweight or obesity. In other words, obese subjects had lower HF values at resting and demonstrated altered cardiovascular hemodynamics and reflex control during exercise and recovery than lean subjects. An attenuated decrease in heart rate after exercise, or heart rate recovery (HRR), has been shown to predict mortality. In NIRS studies, the prefrontal cortex has been more activated during and post aerobic exercise. To investigate whether the manipulation of brain excitability by transcranial direct current stimulation (tDCS) modulates the parasympathetic reactivation after submaximal isocaloric exercise, the effect of tDCS on left dorsolateral prefrontal cortex (DLPFC) in young obese subjects was evaluated.
