What You'll Learn
- 1Explain how exercise increases neurotrophic factors and promotes neurogenesis
- 2Understand the cognitive benefits of aerobic exercise
- 3Apply exercise science to optimize brain health an academic performance
The Explanation
When you exercise, your muscles produce chemical signals including BDNF (Brain-Derived Neurotrophic Factor). BDNF promotes neurogenesis—the growth of new neurons in the hippocampus, the brain region critical for learning.
A 2025 meta-analysis found that aerobic exercise had the greatest impact on adolescent cognitive function, particularly for executive function and attention. Kids with 'fit' brains showed more efficiently organized brain networks.
You don't need to be an athlete. Moderate-intensity aerobic exercise for 60 minutes per week shows measurable benefits. You're building a faster, smarter, more resilient brain that will serve you throughout your life.
Key Terms
BDNF
Protein released during exercise that promotes neuron growth ('Miracle-Gro for the brain')
Neurogenesis
The creation of new neurons, triggered by exercise in the hippocampus
Executive Function
Higher-level cognitive abilities like planning and problem-solving
