However, the prediction errors were less when using Relative IP than Relative FTP (273.5 s versus 303.6 s).  <strong>Conclusion</strong&gt;: A field-based IP test can be used as a benchmark for the determination of XC-MTB athlete ability and preparedness.  Athlete improvements can be tracked using an IP test.}, number={1}, journal={Journal of Science and Cycling}, author={Miller, Matthew C}, year={2014}, month={Jun.}, pages={16-20} }
