DESCRIPTION
Brain Research - LTCY 199 - Summer 2009 - Exercise Boosts Brain PowerTRANSCRIPT
- 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
- exercise improves learning skills by increasing the growth of neurons in the brain
