New research from the University of South Australia suggests that regular physical activity can improve cognitive function in older adults. Conducted in partnership with the US-based AdventHealth Research Institute, the study analyzed data from 585 older adults (aged 65-80 years) and found a significant association between moderate-to-vigorous physical activity and better processing speed, working memory, and executive function.
The study discovered that even small changes to daily activities can have a significant impact on brain health. For example, people who went from doing no moderate-to-vigorous physical activity to just five minutes of exercise per day experienced the largest cognitive gains. Researchers also found a two-way relationship between physical activity and brain health: more exercise leads to better brain health, while less exercise declines it.
UniSA researcher Dr. Maddison Mellow explained that understanding the optimal balance of time spent on sleep, sedentary behavior, and physical activity is crucial for maximizing cognitive performance. The study highlights the importance of prioritizing moderate-to-vigorous physical activity, which can improve processing speed, executive function, and working memory.
Dr. Collins, co-researcher, emphasized that the findings can empower older people to make positive health changes by making conscious decisions about how they spend their time. With one in six people expected to be 60 years or older by 2030, it is essential to support and encourage individuals to age well through regular exercise and healthy lifestyle habits.
While the study’s results are promising, further research is needed to confirm its findings. However, with one-third of the world’s population aged over 65 already living today, this knowledge can serve as a powerful tool for promoting brain health and overall wellness in older adults.
