Determination of Best Criteria to Determine Final and Initial Speeds within Ramp Exercise Testing Protocols
This study compared strategies to define final and initial speeds for designing ramp protocols. V (O(2)max ) was directly assessed in 117 subjects (29 ± 8 yrs) and estimated by three nonexercise models: (1) Veterans Specific Activity Questionnaire (VSAQ); (2) Rating of Perceived Capacity (RPC); (3)...

description | This study compared strategies to define final and initial speeds for designing ramp protocols. V (O(2)max ) was directly assessed in 117 subjects (29 ± 8 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 (30 ± 9 yrs) performed three additional tests with initial speeds corresponding to 50% of estimated V (O(2)max ) and 50% and 60% of measured V (O(2)max ). Significant differences (P < 0.001) were found between V (O(2)max ) measured (41.5 ± 6.6 mL·kg(−1) ·min(−1)) and estimated by VSAQ (36.6 ± 6.6 mL·kg(−1) ·min(−1)) and CRF (45.0 ± 5.3 mL·kg(−1) ·min(−1)), but not RPC (41.3 ± 6.2 mL·kg(−1) ·min(−1)). The CRF had the highest ICC, the lowest SEE, and better limits of agreement with V (O(2)max ) compared to the other instruments. Initial speeds from 50%–60% V (O(2)max ) estimated by CRF or measured produced similar V (O(2)max ) (40.7 ± 5.9; 40.0 ± 5.6; 40.3 ± 5.5 mL·kg(−1) ·min(−1) resp., P = 0.14). The closest relationship to identity line was found in tests beginning at 50% V (O(2)max ) estimated by CRF. In conclusion, CRF was the best option to estimate V (O(2)max ) and therefore to define the final speed for ramp protocols. The measured V (O(2)max ) was independent of initial speeds, but speeds higher than 50% V (O(2)max ) produced poorer submaximal relationships between workload and V (O(2)). |
