Which protocol uses 2-minute stages with predetermined work rates based on gender and height?

• A. Godfrey protocol
• B. McMaster protocol
• C. James protocol
• D. None of the above

Answer: (B)

The test design relies on staged, progressive work rates, with each stage lasting two minutes and the workload chosen in advance based on the individual's gender and height. This means the treadmill speed and incline are preset to hit similar relative effort levels across people of different sizes and sexes, making the results more comparable and the VO2 max estimate more accurate. This two-minute, gender-and-height–calibrated progression is a hallmark of the McMaster protocol, which is why it’s the best choice for this description. Other protocols use different stage lengths or different rules for setting workload, so they don’t match the same two-minute, size-based progression.
