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

• A. A treadmill test with 3 progressive 3-minute stages based on gender and body surface area.
• B. A cycle ergometer test with 3 progressive 3-minute stages based on gender and body surface area.
• C. A cycle ergometer test with 4 progressive 2-minute stages.
• D. A walk-to-exhaustion test.

Answer: (B)

The James protocol is a cycle ergometer graded exercise test that uses three progressive stages, each lasting three minutes, with workloads individualized based on gender and body surface area. This setup lets the cardiovascular system respond to each step and reach a stable state before increasing the load, which helps in obtaining reliable measures of effort and cardiorespiratory response while keeping the test safe and tailored to body size. It is not a treadmill test, it does not use four 2-minute stages, and it isn’t a walk-to-exhaustion test, which is why the cycle ergometer with three 3-minute stages adjusted for sex and body size is the best description.
