Study Reveals Exercise Boosts Brain Health in Seniors, Reducing Cognitive Decline
April 29, 2025
Dr. Maddison Mellow noted that small lifestyle changes can have substantial impacts on brain health, emphasizing the importance of understanding how daily activities interact to influence cognitive outcomes.
Findings suggest that prioritizing physical activity that raises the heart rate is crucial, with the researchers advocating for increased awareness of the importance of exercise as people age.
A new study from the University of South Australia reveals that moderate-to-vigorous physical activity significantly enhances brain health in older adults aged 65-80.
The research indicates a two-way relationship: increased exercise improves brain health, while reduced activity leads to cognitive decline.
Participants who transitioned from no physical activity to even just five minutes of exercise experienced notable cognitive improvements, highlighting the importance of exercise for brain health.
The study found that higher-intensity physical activity is linked to improved processing speed, working memory, and executive function, while lower activity levels correlate with declines in cognitive performance.
Data was assessed from 585 older adults as part of the US-based IGNITE trial, focusing on sleep, sedentary behavior, and different levels of physical activity throughout the day.
Research conducted in partnership with the AdventHealth Research Institute analyzed data from 585 participants in the IGNITE trial, focusing on the effects of physical activity on cognitive function.
With predictions indicating that one in six individuals will be over 60 by 2030, the study underscores the need for strategies to promote healthy aging through physical activity.
The study calls for further longitudinal and experimental research to confirm these findings and better understand the optimal balance of sleep, activity, and sedentary behavior for cognitive performance.
Co-researcher Dr. Audrey Collins highlighted the importance of prioritizing physical activity within the limited 24-hour day to enhance brain health as people age.
Interestingly, the findings did not show significant effects on episodic memory or visuospatial function outcomes.
