Variations in Ramp Slope Affect the Prediction of W´ from a Single Incremental Test

Key Points

  • The aim is to understand how different ramp slopes affect the accuracy of W´ predictions from incremental tests.
  • Conducted an incremental test to assess W´ under various ramp slopes.
  • Compared W´ values from the incremental test against traditional critical work rate (CWR) methodology.
  • Evaluated the effect of a supra-critical power (CP) work bout following the test.
  • Incremental tests consistently underestimated W´ compared to traditional CWR values.
  • The ramp slope had no significant effect on the underestimation of W´.
  • Adding a supra-CP work bout reduced but did not eliminate the variability in W´ estimation.

Abstract

W´ determination from a RI test results in an underestimation compared to values obtained with traditional CWR methodology, irrespective of the imposed ramp slope. Although adding a supra-CP work bout immediately following termination of the RI test may reduce this difference, substantial variability in W´ estimation remains.
