Most of know that exercise is good for the brain, but how frequently do you have to exercise to benefit your memory\u2014and how long do the effects last?<\/p>\n
Researchers from the University of Iowa wanted to know the answers to these questions, so they created a study to better understand how exercise can benefit the cognitive abilities of older people.<\/p>\n
For the first part of the study, the scientists instructed 34 older participants (ages 60-80) to use a stationary bike for two separate sessions. Overall, the participants were healthy but didn\u2019t exercise on a regular basis.<\/p>\n
For the first session on the stationary bike, the cycling was light. But the second session required a more strenuous pedaling for 20 minutes.<\/p>\n
All the participants took memory tests and underwent MRIs before and after each session so the researchers could monitor their brain activity in regions associated with working memory.<\/p>\n
Some of the participants showed increased brain connectivity in the regions connected to memory. They also did better on working memory tests, but the benefits only lasted for a short time.<\/p>\n
Next, the participants followed a 12-week aerobic training program that involved riding a stationary bike for 50 minutes, three times a week.<\/p>\n
\u00a0<\/p>\n
Half the group was told to pedal lightly (and the pedals rotated on their own automatically) and the other half was told to pedal moderately.<\/p>\n
Although both groups in the 12-week study improved their brain connectivity and performed better on the memory test, there was no difference in the benefits compared to the group that only exercised twice.<\/p>\n
\u201cIn terms of behavioral change and cognitive benefits from physical activity, you can say, \u2018I\u2019m just going to be active today. I\u2019ll get a benefit,\u2019\u201d explains lead researcher Michelle Voss, Ph.D. \u201cSo, you don\u2019t need to think of it like you\u2019re going to train for a marathon to get some sort of optimal peak of performance. You just could work on it day by day to gain those benefits.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"
