Exercising Several Hours Each Week Improves Cognition in Older Adults, Study

reports a study by researchers at University of Miami Miller School of Medicine analyzing data on over 11,000 older people “found that people who exercised about 52 hours over a period of about six months showed the biggest improvements in various thinking and speed tests,” but less so in memory. Data indicate that “on average, people exercised for about an hour, three times a week” and that “the effect applied to both people without cognitive decline as well as those with mild cognitive impairment or dementia.” Notably, researchers only observed a “strong correlation between exercise and brain function...when they looked at the overall time people spent being physically active,” meaning “they did not find associations between improvements in thinking and the frequency, intensity or length of time people exercised.” The findings were published in Neurology. http://time.com/5294493/exercise-healthy-brain-aging/
