Maximal Oxygen Consumption

Maximal exercise oxygen consumption is measured during screening using a stationary cycling ergometer and a metabolic cart for some exercise related protocols.
Maximal Exercise Test


An electrocardiogram (EKG, or ECG) is taken to screen for pre-existing cardiac abnormalities during some protocols. If over the age of 40 years, a cardiac stress test in the hospital lab may be performed for some of the protocols.

In-Patient Study Procedures

All study procedures once enrolled in the research protocol take place in the GCRC. Hospital-like rooms are assigned to our participants, with private bathrooms and showers. Study procedures take place during one to two days, with one to two overnight stays in the GCRC.
