Walking and strength training are often recommended for physical fitness, but recent research highlights their significant benefits for brain health. According to Dr. Shukla, a neurologist at the University of California, San Francisco, these exercises improve blood flow to the brain, support the growth and function of brain cells, enhance memory, and help reduce inflammation.
A 2024 study published in the Journal of Alzheimer's Disease found that older adults who engaged in regular walking and strength training showed a 30% lower risk of cognitive decline compared to those who did not. The study followed 1,200 participants over five years, confirming the long-term benefits of these activities.
Dr. Shukla emphasizes that even moderate exercise, such as a 30-minute walk five times a week and two sessions of strength training, can yield these benefits. She notes that the combination of aerobic and resistance exercises is particularly effective for brain health.
These findings are supported by the World Health Organization, which recommends at least 150 minutes of moderate-intensity aerobic activity per week for adults, along with muscle-strengthening activities on two or more days. The WHO highlights that such exercise reduces the risk of dementia and improves overall cognitive function.
