New research suggests that older adults can maintain good brain health by exercising early in the day. This study, published in the Journal of Applied Physiology, found that morning exercises mitigate the impact of prolonged sitting on brain blood flow in overweight or obese older adults. This suggests that exercise should be part of one’s daily routine to help prevent the slowing down of brain blood circulation associated with aging, as previously noted. Here Grace Olson, NaturalNews.com, reflects on staying fit and improving your memory with exercise:

“Regular exercise is a key component of a healthy lifestyle, but its benefits go beyond just strengthening muscles and reducing fat. Researchers from the University of Maryland (UMD) found that exercising for at least 30 minutes each day can help improve memory. Their study, which appeared in the Journal of the International Neuropsychological Society, is one of many that seek to explore the connection between exercise and cognitive function.

How does exercise affect the brain?

Aerobic exercise improves memory and brain function by promoting neurogenesis. Neurogenesis refers to the growth of new cells in the brain, which is faciliated by an increase in the production of brain-derived neurotrophic factor (BDNF).

BDNF is a brain protein involved in the growth, maturation, maintenance and survival of nerve cells. Besides being active at the synapses, where communication between nerve cells occur, BDNF is also found in brain regions that control important physical activities, such as eating and drinking. Additionally, BDNF influences learning and memory as it regulates the ability of synapses to adapt in response to experience.

According to studies, exercise prompts the release of large amounts of BDNF. High levels of BDNF, in turn, boosts memory and improves brain function. (Related: Regular exercise can keep dementia at bay – adding more hours reduces the brain’s aging process.)

Despite establishing this link, scientists are still unsure about the right amount of exercise needed to acquire this benefit. Research is still ongoing to determine the right combination of exercise intensity and duration that can produce desirable cognitive outcomes. The present study contributed to the search by exploring how acute exercise – a single bout of exercise – can affect semantic memory.

Semantic memory is the recollection of information not related to individual experiences. This refers to memories associated with language, names and words. Recent studies suggest that the hippocampus, the brain region that regulates emotion, learning and memory, contributes to semantic memory.”
