A new study in the journal Current Biology shows that physical exercise after learning improves memory and memory traces, but only if the exercise is done in a specific time window and not immediately after learning. In the study, researchers tested the effects of a single session of physical exercise after learning on memory consolidation and long-term memory. The scientists found that those who exercised four hours after their learning session retained the information better two days later than those who exercised either immediately or not at all. The MR images also showed that exercise after a time delay was associated with more precise representations in the hippocampus, an area important to learning and memory, when an individual answered a question correctly. http://www.sci-news.com/othersciences/physiology/physical-exercise-long-term-memory-03959.html
