Highly trained endurance athletes are needed for research about a certain protein, and how it affects cognition in trained and untrained individuals.

Rexi Parcells, a graduate student at the University of Texas, is looking for athletes between the ages of 20 and 29 for her studies about a protein called Cathepsin B.

During a two-hour visit, participants will undergo cognitive testing, a treadmill VO2 max test to examine their cardiorespiratory fitness level, body composition testing and blood testing. Each will be entered into a drawing for a $100 gift card.
