Study Notes
Benefits of Exercise for Brain Health
-
Physical activity reduces risks of heart disease, stroke, diabetes, weight gain, low blood pressure, and depression
-
Exercise can improve memory and thinking skills by changing the brain, specifically increasing the size of the hippocampus
-
Aerobic exercise (e.g., walking) is most effective in boosting hippocampus size
-
Resistance training, balance, and muscle toning exercises do not appear to have the same effect
Global Dementia Concerns
-
One new dementia case is detected globally every four seconds
-
By 2050, estimates project more than 115 million people worldwide will have dementia
Exercise's Impact on the Brain
-
Exercise enhances memory and thinking in direct and indirect ways
-
Direct benefits include reduced insulin resistance, inflammation, and stimulation of growth factors (influencing brain cell health, blood vessel growth, and new cell creation)
-
Indirect benefits include improved mood, sleep, decreased stress and anxiety, all of which are factors in cognitive well-being
-
Studies show people who exercise have larger prefrontal cortex and medial temporal cortex volumes (brain regions controlling thinking and memory) compared to non-exercisers
Exercise Recommendations
-
A study participants walked briskly for an hour, twice a week (120 minutes weekly moderate intensity)
-
Standard recommendations for moderate physical activity are 150 minutes per week.
-
For beginners, start with shorter durations and incrementally increase by 5-10 minutes per week
-
Alternative moderate-intensity activities include swimming, stair climbing, tennis, squash, dancing, strenuous household chores (intense mopping, raking)
-
Tips for establishing a routine include joining classes, exercising with a friend, tracking progress, or hiring a personal trainer
-
Regular exercise should be considered a habit, similar to taking medicine, as it is beneficial for overall health.
