The Godfrey protocol uses which type of exercise equipment?

• A. Cycle ergometer
• B. Treadmill
• C. Elliptical
• D. Rowing machine

Answer: (A)

The Godfrey protocol is a cycling-based graded exercise test. It uses a cycle ergometer because this equipment provides precise, reproducible control of work rate (measured in watts) while the rider remains seated and stable. That stability makes it easier to monitor metabolic responses—like oxygen uptake and heart rate—and to compare results across sessions or individuals without the variability that comes from running form, balance, or weight-bearing movement. Incremental resistance can be applied in consistent steps, and the cadence can be maintained, which reduces factors that might alter the data outside of true fitness changes. These features are key for a protocol designed to assess aerobic capacity and related metabolic responses in a controlled way. Other modes, such as a treadmill, involve gait mechanics and balance that introduce more variability and are not as tightly standardized for this particular protocol. Elliptical or rowing machines would likewise introduce different movement patterns and measurement assumptions, making them less aligned with the protocol’s standardized approach.
