Mental, physical exercises produce distinct brain benefits (Science Daily):
“Cognitive brain training improves executive function whereas aerobic activity improves memory, according to new Center for BrainHealth research at The University of Texas at Dallas…healthy adults who participated in cognitive training demonstrated positive changes in executive brain function as well as a 7.9 percent increase in global brain flow compared to study counterparts who participated in an aerobic exercise program. The aerobic exercise group showed increases in immediate and delayed memory performance that were not seen in the cognitive training group.
“Most people tell me that they want a better memory and notice memory changes as they get older,” said Dr. Mark D’Esposito…“While memory is important, executive functions such as decision-making and the ability to synthesize information are equally, if not more so, but we often take them for granted. The takeaway: Aerobic activity and reasoning training are both valuable tools that give your brain a boost in different ways.”
Study: Distinct Brain and Behavioral Benefits from Cognitive vs. Physical Training: A Randomized Trial in Aging Adults (Frontiers in Human Neuroscience)
- Abstract: Insidious declines in normal aging are well-established. Emerging evidence suggests that non-pharmacological interventions, specifically cognitive and physical training, may counter diminishing age-related cognitive and brain functions. This randomized trial compared effects of two training protocols: cognitive training (CT) vs. physical training (PT) on cognition and brain function in adults 56–75 years. Sedentary participants (N = 36) were randomized to either CT or PT group for 3 h/week over 12 weeks. They were assessed at baseline‑, mid‑, and post-training using neurocognitive, MRI, and physiological measures. The CT group improved on executive function whereas PT group’s memory was enhanced…The preliminary evidence indicates that increased cognitive and physical activity improves brain health in distinct ways. Reasoning training enhanced frontal networks shown to be integral to top-down cognitive control and brain resilience…Exercise did not improve cerebrovascular response, although CBF increased in hippocampi of those with memory gains. Distinct benefits incentivize testing effectiveness of combined protocols to strengthen brain health.
