tDCS Reduces Motor Slowing in Athletes and non-Athletes.

Link – Anodal transcranial direct current stimulation reduces motor slowing in athletes and non-athletes. Abstract BACKGROUND: Motor fatigability describes a phenomenon that occurs when exhaustive exercise or physically demanding tasks are executed over an extended period of time. Concerning fast repetitive movements, it is noticeable by a reduction in movement speed (motor slowing, MoSlo) and […]
