Here's a possible strategy to boost" memory-exercise four hours after you
learn something. In a study published in the July 11, 2016, Current Biology,
researchers found that exercise after learning may improve your memory of the
new information, but only if done in a specific time window *2.
(In the study, 72 participants learned 90 picture-location associations mentally
linking an image with new information in order to improve recall over a
40-minute period. They were then randomly assigned to one of (1) three groups:
one group exercised immediately, the second exercised four hours later, and the
third did not exercise. The exercise routine consisted of 35 minutes of interval
10/training on a fitness bike at an intensity of up to 80% of maximum heart rate.
After 48 hours, the participants' memory was tested while their brains were
scanned*4 via MRI*5. Those who exercised four hours after the learning session
retained*6 information better than the other two groups. The MRI also showed
the hippocampus, the brain region involved with learning and memory,
-
that
(2)
15 was more active when information was recalled correctly.
Newly learned information turns into long-term knowledge through a process
that requires certain brain chemicals that are released during exercise, but more
research is needed to understand (3) this phenomenon. (4) It is also not clear why
four hours was more beneficial, or if another time frame might produce a similar
20 effect.
