Learning a second language as an adult is difficult. But the process may be eased if you exercise while learning.
A new study reports that working out during a language class amplifies people’s ability to memorize, retain and understand new vocabulary. The findings provide more evidence that to engage our minds, we should move our bodies.
In recent years, a wealth of studies in both animals and people have shown that we learn differently if we also exercise. Lab rodents given access to running wheels create and maintain memories better than animals that are sedentary, for instance. And students consistently perform better on academic tests if they participate in some kind of physical activity during the school day.
Many scientists suspect that exercise alters the biology of the brain in ways that make it more malleable and receptive to new information, a process that scientists refer to as plasticity.
But many questions have remained unanswered about movement and learning, including whether exercise is most beneficial before, during or after instruction and how much and what types of exercise might be best.
So for the new study, which was published recently in PLOS One, researchers in China and Italy decided to home in on language learning and the adult brain.
Language learning is interesting. As young children, almost all of us picked up our first language easily. We didn’t have to be formally taught; we simply absorbed words and concepts.
But by early adulthood, the brain generally begins to lose some of its innate language capability. It displays less plasticity in areas of the brain related to language. As a result, for most of us, it becomes harder to learn a second language after childhood.
To see what effects exercise might have on this process, the researchers first recruited 40 college-age Chinese men and women who were trying to learn English. The students had some facility with this second language but were far from proficient.
The researchers then divided the students into two groups. Those…
