and physiological decline.”
For this study, men aged 64-75 years underwent an exercise test to measure their aerobic fitness. The men, whose physical fitness levels varied greatly, then performed a Stroop test to measure their selective attention, executive function, and reaction time.
The Stroop test involves reading the word for a colour, such as "blue, green, red," but asking the subject to name the colour of the word rather than read the word itself.
When the color of the letters doesn’t match the word, it takes the brain longer to react, as you can see by taking the Stroop test above. The length of someone’s reaction time is used as a measurement of brain function.
