Jan 16, 2024
Dr Jill Barnes, an expert on the brain and exercise from the University of Wisconsin-Madison, discusses the effect of exercise on cognitive function, brain blood flow, dementia risk, and progression. Topics include measuring brain blood flow, regional blood flow in the brain, the relationship between exercise intensity and brain health, resistance training and cognitive function, the impact of exercise on brain endothelial function, and exercise's influence on the risk of stroke and dementia.

Episode notes
Exercise Boosts Resting Brain Blood Flow
- People with higher fitness levels have slightly higher resting brain blood flow.
- One-year aerobic training in middle-aged adults can increase brain blood flow at rest.
Multimodal Approaches Benefit Cognition
- Multimodal lifestyle approaches combining exercise, brain activity, diet, and social interaction show promise in cognitive maintenance.
- Simply doing puzzles or exercise alone is less impactful than combined efforts for brain health.
Exercise Intensity Matters for Brain Health
- Higher intensity aerobic exercise is likely better for brain health due to improved cardiovascular fitness.
- Fitness improvements indicated by VO2 max increases typically associate with better brain outcomes.
