Here’s another reason why it’s a good idea to hit the gym: it can improve memory. A new Georgia Institute of Technology study shows that an intense workout of as little as 20 minutes can enhance episodic memory, also known as long-term memory for previous events, by about 10 percent in healthy young adults.
The Georgia Tech research isn’t the first to find that exercise can improve memory. But the study, which was just published in the journal Acta Psychologica, took a few new approaches. While many existing studies have demonstrated that months of aerobic exercises such as running can improve memory, the current study had participants lift weights just once two days before testing them.
“Our study indicates that people don’t have to dedicate large amounts of time to give their brain a boost,” said Lisa Weinberg, the Georgia Tech graduate student who led the project.
Although the study used weight exercises, Weinberg notes that resistance activities such as squats or knee bends would likely produce the same results. In other words, exercises that don’t require the person to be in good enough to shape to bike, run or participate in prolonged aerobic exercises.
