The Godfrey protocol is best described as which of the following tests?

• A. A 1-minute incremental cycle ergometer test for paediatric CF patients, with workload increments based on height.
• B. A treadmill test for adults with COPD.
• C. A running test for athletes.
• D. A swimming test for endurance.

Answer: (A)

The Godfrey protocol is a pediatric exercise test designed for children with cystic fibrosis that uses a cycle ergometer with 1-minute stages. The workload increases are determined by the child’s height, not just a fixed speed or generic ramp, so the effort scales to body size and provides a safe, standardized way to push toward maximal exertion. This combination—cycle ergometer modality, short 1-minute increments, and height-based progression—fits the needs of young CF patients by controlling for growth-related differences while allowing accurate assessment of functional capacity and cardiorespiratory response. The other options describe tests that target different populations (adults with COPD, athletes, or swimmers) and use different modalities, so they don’t match the specific characteristics of the Godfrey protocol.
