Psychobiological Responses Following Exercise and Brain Stimulation

Subject will complete a Cycling exercise at 65% of HRR for 20 minutes and then a High-definition transcranial direct current stimulation (HD-tDCS) is a non-invasive brain stimulation technique that uses small electrodes to deliver weak electric currents to the scale. Transcranial direct current stimulation (tDCS) uses weak direct currents of the order of 0.5 mA to 4 mA to modulate cortical activity by exciting or suppressing underlying neurons.

"A widely used psychological assessment tool designed to measure both state and trait anxiety. 40 self-report items rated on a 4-point Likert scale (1 = Almost Never to 4 = Almost Always). Higher scores indicate higher levels of anxiety. Scores are compared to normative data to determine if they fall within the range of typical or clinical anxiety."

"The Visual Analogue Scale for Anxiety (VASA) is a 100-millimeter line that helps people measure how anxious they feel. The scale has a mark on the left end that indicates not at all anxious and a mark on the right end that indicates very anxious."
