“…Several neurochemicals, including brain-derived neurotrophic factor (BDNF), insulin-like growth factor-1 (IGF-1), and vascular endothelial growth factor (VEGF), are currently considered key proteins that mediate downstream effects of exercise on the brain and cognition (Cotman et al, 2007). As a single bout of physical exercise may lead to an increase in BDNF level (Ferris et al, 2007;Griffin et al, 2011), these exercise-increased neurotrophins may contribute to a reduction in mood disorders and to the protection and regeneration of various tissues resulting in increased cognitive performance in humans (Hansen et al, 2001;Rojas Vega et al, 2008;Zoladz and Pilc, 2010).…”
