Exercise can boost kids’ vocabulary growth. A new research has come out with this finding.
The study, published in the Journal of Speech Language and Hearing Research, detailed one of the first studies on the effect of exercise on vocabulary learning in children. Children ages 6 to 12 were taught new words before doing one of three things—swimming, taking part in CrossFit exercises or completing a colouring sheet. The children who swam were 13 per cent more accurate in follow up tests of the vocabulary words.
It makes sense to the lead researcher, Maddy Pruitt, herself a former college swimmer who now regularly takes CrossFit classes. “Motor movement helps in encoding new words,” she said, explaining that exercise is known to increase levels of brain-derived neurotrophic factor, a protein Pruitt describes as the “Miracle-Gro of the brain.”
Why then, did swimming make a difference while CrossFit did not? Pruitt attributed it to the amount of energy each exercise demands of the brain. Swimming is an activity the kids could complete without much thought or instruction. It was more automatic, while the CrossFit exercises were new to them. The children needed to learn the moves, which required mental energy.
Pruitt conducted the research as part of her Master’s Capstone Project and graduated in 2020. She now works as a speech language pathologist at an elementary school in South Carolina, where she puts her findings into practice. “My sessions are very rarely at a table,” she said. “I’ll take my kids out to the playground or we’ll take a walk around the schchild
