This study compared strategies to define final and initial speeds for designing ramp protocols. was directly assessed in 117 subjects (  yrs) and estimated by three nonexercise models: (1) Veterans Specific Activity Questionnaire (VSAQ); (2) Rating of Perceived Capacity (RPC); (3) Questionnaire of Cardiorespiratory Fitness (CRF). Thirty seven subjects (  yrs) performed three additional tests with initial speeds corresponding to 50% of estimated and 50% and 60% of measured . Significant differences were found between measured (  mL·kg−1·min−1) and estimated by VSAQ (  mL·kg−1·min−1) and CRF (  mL·kg−1·min−1), but not RPC (  mL·kg−1·min−1). The CRF had the highest ICC, the lowest SEE, and better limits of agreement with compared to the other instruments. Initial speeds from 50%–60% estimated by CRF or measured produced similar ( ; ;  mL·kg−1·min−1 resp., ). The closest relationship to identity line was found in tests beginning at 50% estimated by CRF. In conclusion, CRF was the best option to estimate and therefore to define the final speed for ramp protocols. The measured was independent of initial speeds, but speeds higher than 50% produced poorer submaximal relationships between workload and .
