Physical exercise at any age can improve brain function and memory, according to new research.
The University of South Australia said findings from 133 systematic research reviews found that regular exercise improved general cognition, memory and executive function.
This was true across all age groups and among healthy people and those with clinical conditions.
The study covered 2724 randomised, controlled trials involving 258,279 participants.
It found that:
- Low to moderate intensity exercise had the greatest benefits for brain function and memory
- Children and adolescents showed the greatest improvements in memory, while people with ADHD saw the biggest gains in executive function
- Yoga, Tai Chi, and exergames (active video games) delivered the most significant cognitive benefits
Lead researcher, Dr Ben Singh, said the findings provided a comprehensive understanding of how different types, intensities, and durations of exercise influenced cognitive function.
“Exercise has a profound effect on physical health, but we also know it benefits brain function,” he said.
“What this study confirms is that even low-intensity exercise – like yoga or walking – can improve cognition, making it accessible to people of all ages and abilities.”
Dr Singh said the gains were evident within one to three months.
Senior researcher, Professor Carol Maher said exercise should be encouraged as a cognitive health strategy across all ages and fitness levels.
“Cognitive decline and neurodegenerative diseases are growing global health concerns, underscoring the urgent need to identify effective strategies to preserve and enhance cognitive function across the lifespan,” Prof Maher said.
“This study presents compelling evidence that exercise should be integrated into healthcare and education settings to promote cognitive well-being.”
