Groundbreaking research from the University of South Australia has confirmed that exercise can significantly enhance brain function and memory, benefiting individuals of all ages, from children to older adults. The study, the largest of its kind, underscores the importance of regular physical activity as a powerful tool for cognitive health.
In an extensive umbrella review that analyzed 133 systematic reviews and included data from 2724 randomized controlled trials involving over 258,000 participants, the researchers found compelling evidence that exercise positively impacts cognition, memory, and executive function in both healthy individuals and those with clinical conditions. The study highlights exercise as a key, inclusive activity that promotes cognitive well-being.
The findings revealed that low- to moderate-intensity exercise offered the greatest benefits for brain function and memory. Children and adolescents showed the most significant improvements in memory, while individuals with ADHD experienced the most notable gains in executive function. Additionally, mind-body exercises like yoga and Tai Chi, as well as exergames (active video games), were identified as providing the most substantial cognitive benefits.
Dr. Ben Singh, the lead researcher at the University of South Australia, explained that the study provides a thorough understanding of how various types, intensities, and durations of exercise influence brain health. “We found that benefits were evident within just 1-3 months, highlighting how even brief bursts of activity can make a meaningful difference,” Dr. Singh said. “This research suggests that trying new activities could be a key factor in keeping the brain engaged and healthy.”
The study found particular benefits for children and teenagers, with exercise playing a vital role in developing memory. For individuals with ADHD, exercise was shown to improve focus, reduce impulsivity, and enhance executive function.
Professor Carol Maher, a senior researcher on the study, emphasized the importance of promoting exercise as a strategy to combat cognitive decline and neurodegenerative diseases. “Cognitive decline is a growing global health concern, and it is crucial to identify strategies to preserve cognitive function throughout life,” Prof. Maher stated. “This study presents strong evidence that exercise should be incorporated into healthcare and education systems to foster cognitive well-being.”
The findings suggest that even small amounts of exercise can have a significant impact on memory and brain function, particularly for those at higher risk of cognitive decline. The research advocates for the inclusion of exercise in clinical and public health guidelines to promote long-term cognitive health.
