Executive Summary
- Moderate-to-vigorous physical activity is associated with better cognitive performance in older adults, particularly in processing speed, working memory, and executive function.
- Even a minimum of 5 minutes of moderate-to-vigorous exercise can provide cognitive benefits.
- The AdventHealth Neuroscience Institute is conducting the FLAME study to further explore the long-term effects of moderate-intensity exercise on cognitive health and Alzheimer's risk.
Event Overview
A recent study published in the journal Age and Ageing highlights the positive impact of moderate-to-vigorous physical activity on the neurocognitive functions of older adults. The study, which analyzed data from the Investigating Gains in Neurocognition in an Intervention Trial of Exercise (IGNITE), found that even small amounts of physical activity, as little as 5 minutes, can significantly improve processing speed, working memory, and executive function. This research underscores the importance of incorporating physical activity into daily routines to promote brain health and potentially mitigate age-related cognitive decline.

Key Details & Data Points
- What: Moderate-to-vigorous physical activity is associated with better cognitive performance in older adults, specifically improved processing speed, working memory, and executive function. Even short durations of exercise can be beneficial.
- Who: The study focused on adults aged 65-80. Key researchers include Audrey Collins, PhD, Maddison Mellow, PhD, and Kirk Erickson, PhD. Expert opinions are provided by Raphael Wald, PsyD, and Gary Small, MD.
- When: The IGNITE study's baseline data was analyzed. The FLAME study is currently underway. The study from AdventHealth was published April 29, 2025. The Medical News Today article references a study recently published in the journal Age and Ageing.
- Where: The IGNITE study was a multi-site clinical trial conducted in the U.S. The FLAME study is also a national multi-site effort.
Key Statistics:
- Key statistic 1: 648 (number of adults between 65 and 80 in the IGNITE study)
- Key statistic 2: 5 minutes (minimum duration of moderate-to-vigorous exercise that can provide cognitive benefits)
- Key statistic 3: $11 million (funding from the National Institutes of Health (NIH) for the FLAME study)
Analysis & Context
The findings from the IGNITE study, as reported by both AdventHealthMD and Medical News Today, consistently point to the cognitive benefits of moderate-to-vigorous physical activity in older adults. Medical News Today provides a broader perspective by including commentary from external experts who emphasize the importance of exercise for brain health and the need for accessible prevention options for individuals with limited mobility. The AdventHealth article focuses on the ongoing FLAME study, highlighting the institution's continued research efforts in this area. The convergence of these reports strengthens the evidence supporting the role of physical activity in promoting cognitive well-being in aging populations.
Notable Quotes
Our results show that how we choose to spend our time across the 24-hour day may be differentially related to our brain health. We found that the need to prioritize physical activity, especially physical activity that gets our heart rates up, is key.
The key is to exert oneself enough to push the heart and lungs to pump oxygen and nutrients to the brain. We know that such aerobic exertion increases brain-derived neurotrophic factor (BNDF) — a protein that improves brain cell communication. Cardiovascular conditioning also has been shown to grow the size of the brain’s hippocampal memory center.
Conclusion
The study reinforces the importance of moderate-to-vigorous physical activity for maintaining and improving cognitive function in older adults. Even short bursts of exercise can yield significant benefits. Ongoing research, such as the FLAME study, aims to further elucidate the long-term effects of exercise on cognitive health and Alzheimer's risk. These findings emphasize the need for public health initiatives promoting physical activity as a key strategy for healthy aging and dementia prevention.
