Transcript

  • 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
  • Importance?
    Youth
  • 11. Importance?
    Elderly
