How Exercise Literally Rebuilds Your Brain

Shawn Stevenson

Stevenson presents research on exercise-induced neuroplasticity, covering BDNF production, hippocampal neurogenesis, and the cognitive benefits of resistance training versus cardio. He argues that exercise is the single most effective intervention for cognitive health.

Canon

•
The relationship between exercise and cognitive function is so strong that physical activity predicts academic performance better than study time -- the body and brain are not separate systems
Stevenson presents data showing that students who exercise before school perform better academically than students who study during the same time period. The relationship between physical movement and cognitive performance is stronger than the relationship between study time and cognitive performance.

Highlights

•
Exercise produces BDNF (brain-derived neurotrophic factor), which John Ratey calls Miracle-Gro for the brain -- no pharmaceutical produces the same breadth of cognitive benefits as a single bout of moderate exercise
Stevenson presents the BDNF research: a single 30-minute session of moderate exercise increases BDNF levels by 200-300%. BDNF promotes neurogenesis (new brain cell growth), strengthens synaptic connections, and protects existing neurons from degeneration. No drug replicates this breadth of benefit.
