Which of the following is NOT a performance submaximal test?

• A. Self-Paced Walking Test (SPWT)
• B. Rockport 1-Mile Walk Test (Rockport Fitness Test)
• C. Timed Up and Go (TUG)
• D. 6-Minute Walk Test (6MWT)

Answer: (B)

A performance submaximal test is one where you perform at a submaximal level and obtain a direct performance outcome (like distance covered or time to complete a task) to gauge endurance. The Rockport 1-Mile Walk Test is different: its main purpose is to estimate VO2 max from a single mile walk plus post‑exercise heart rate. It uses the result to predict aerobic capacity rather than providing a direct submaximal endurance performance measure across a graded or repeated submaximal workload. In contrast, the Self-Paced Walking Test and the 6-Minute Walk Test yield clear performance outcomes (pace or distance) under submaximal effort, and Timed Up and Go assesses functional performance. For that reason, the Rockport test is the one that is not categorized as a performance submaximal test.
