Washington: Climbing a tree and balancing ona beam can dramatically boost cognitive skills, according to a new study which found that working memory can be improved in just a couple of hours of these physical exercises.
Researchers in the Department of Psychology at the University of North Florida are the first to show that pro prioceptively dynamic activities, like climbing a tree, done over a short period of time have dramatic working memory benefits.
Working memory, the active processing of information, is linked to performance in a wide variety of contexts from grades to sports. "Improving working memory can have a beneficial effect on so many areas in our life, and it's exciting to see that proprioceptive activities can enhance it in such a short period of time," said Tracy Alloway, an associate professor.
The aim of this study was to see if proprioceptive activities completed over a short period of time can enhance working memory performance. Proprioception, the awareness of body positioning and orientation, is associated with working memory. It was also of interest whether an acute and highly intensive period of exercise would yield working memory gains.
The researchers recruited adults ages 18 to 59 and tested their working memory. Next, they undertook proprioceptively dynamic activities, designed by the company Movnat, which
required proprioception and at least one other element, such as locomotion or route planning.
In the study, such activities included climbing trees, walking and crawling on a beam approximately 3 inches wide, moving while paying attention to posture, running barefoot,
navigating over, under and around obstacles, as well as lifting and carrying awkwardly weighted objects.
After two hours, participants were tested again, and researchers found that their working memory capacity had increased by 50 per cent, a dramatic improvement. The researchers also tested two control groups. The first was a college class learning new information in a lecture setting to see if learning new information improved working memory.
The second was a yoga class to see if static proprioceptive activities were cognitively beneficial. However, neither control group experienced working memory benefits. Proprioceptively dynamic training may place a greater demand on working memory than either control condition because as environment and terrain changes, the individual recruits working memory to update information to adapt appropriately, researchers said.
Though the yoga control group engaged in proprioceptive activities that required awareness of body position, it was relatively static as they performed the yoga postures in a small space, which did not allow for locomotion or navigation. The research was published in the journal Perceptual and Motor Skills.
