Free maximum aerobic capacity testing (VO2max) for participation in exercise science study

Hi,
I am looking to recruit participants who can run a mile under 5 minutes or a 10k under 16min for an exercise science study at UT. The study examines output from accelerometers. You will have to visit the exercise physiology lab on 2 seperate days for about 35 minutes on each day and complete progressive walking and running 3 minute stages with the maximum running speed being 12.4mph. In return for your participation, I could test your maximum aerobic capacity (VO2max) for free during a 3rd visit (takes about 20min). The testing would take only 35 minutes each day. I need four more good runners and hope to find some volunteers in this forum.
Regards,
Dinesh.
