Stated track and field at the age of 77. Worlds record in almost every event and earned 750+ gold medals. Compared to a group of older adults in their 70s (sedentary) Although she had some decline from this group due to age, she did preform much higher than expected for a person at her age group. Specifically found a well-preserved corpus colosum (between the two hemispheres) Case study: an extensive study of one individuals (or a small group of individuals) Compared low exercisers (less than 5 hours a week) to high exercisers (more than 5) Measured erps during a cognitive task (oddball) When the odd sound is found participants press a button. Results: high exercisers had significantly higher p300 amplitude compared to low exercisers.
