1. Exercise Boosts Brain Power
Mary Grace Reed

2. Benefits of exercise
Weight control
Energy improvement
Decrease risks for diabetes, heart disease, and stroke
Enhances learning and prevents memory loss

3. People who exercise have half the risk of getting Alzheimer's Disease or any other type of Dementia.

4. Exercising improves long term memory, reasoning, problem solving, abstract thinking, and more.

5. Aerobic exercise has been shown to be more beneficial than toning exercise such as weight lifting.

6. definitions
Neuron nerve cell
Neurogenesis growth of new neurons in the brain
Hippocampas part of brain that controls memory and learning
BDNF brain derived neurotrophic factor
A protein which builds and nourishes nerve cells
neuron

7. Exercise helps move more oxygen to the brain.
Exercise has been shown to increase levels of BDNF.
BDNF increases the number of nerve cells in the hippocampas.
Oxygen

8. Experiment:
young & old mice
2 groups exercise & no exercise
exercise group walked on wheel for 1 month
Morris water maze
timed on how fast 2 groups could navigate maze
brains analyzed
Journal of Neuroscience, September 21, 2005

9. Findings:

• exercisers of both ages learned to navigate faster
• 10. new neurons were formed in the brains of exercisers

Conclusion:

• exercise improves learning skills by increasing the growth of neurons in the brain
