“Aerobic workout triggers new mobile growth inside the hippocampus (memory hub). This increase in new neurons is known as neurogenesis. Exercise promotes neurogenesis by means of growing BDNF (Brain-Derived Neurotrophic Factor). By increasing BDNF, aerobic workout boosts your reminiscence and makes you smarter. You can add neurogenesis on your listing of motives to workout every day.” —Christopher Bergland (The Athlete’s Way: Sweat and the Biology of Bliss, 2007)
When I published The Athlete’s Way in 2007, the idea that aerobic exercise should enhance reminiscence by means of triggering the manufacturing of BDNF—which is like Miracle-Gro for the mind and stimulates the beginning of new neurons (neurogenesis) in the hippocampus—turned into a notably new idea.

Over the past decade, infinite human and animal studies have recognized a hyperlink between aerobic workout, hippocampal neurogenesis, and advanced memory. Yesterday, I pronounced on yet any other study (McGreevy et al., 2019), which determined that setting mice on a six-week aerobic regimen inspired neurogenesis in unique regions of the hippocampus and advanced rankings on memory exams.
In addition to weekly workout bulking up the hippocampus over the years, there may be a growing frame of evidence that one bout of workout boosts reminiscence at once after an exercising. Last yr, a study (Suwabe et al., 2018) by using researchers in Japan reported that an unmarried 10-minute bout of mild exercise inclusive of yoga or tai chi stronger reminiscence by way of stimulating the dentate gyrus vicinity of the human hippocampus.
As the authors give an explanation for, “A single 10-minute bout of very mild-depth exercising (30% VO2 max effort) effects in fast enhancement in sample separation and growth in functional connectivity between hippocampal DG/CA3 and cortical regions (i.E., parahippocampal, angular, and fusiform gyri). These results advise that quick, very light workout hastily enhances hippocampal memory characteristic.”
Increasingly, the holy grail for neuroscientists studying the mental benefits of exercise is to dial in on the optimum “dose” (intensity × length) of cardiovascular exercise or clean/light motion that is required to elicit various cognitive effects in the short- and long-term.
This week, a brand new study from the University of Maryland, “Semantic Memory Activation After Acute Exercise in Healthy Older Adults,” changed into posted online ahead of print in the Journal of the International Neuropsychological Society. This study advances our expertise of the dose-response needed to activate brain circuits related to semantic reminiscence. Generally speaking, this refers to recollections that relate to language, phrases, and names.
