The validity of this concept has not been studied previously in cyclists with different performance levels. As a result, we classified 120 cyclists in our study as recreationally trained, trained, well trained or professional, based on their maximal oxygen consumption. Participants performed a functional threshold power testing protocol based on a 20-min time trial and a 60-min time trial, separated by a 72-hour rest. Sixty-minute maximal power was successfully modeled with 20-min maximal power and performance group using 2/3 of the dataset (R2=0.77, 95% CrI [0.74, 0.79]) with different coefficients for each group: Professional: PO60min=PO20min × 0.96; well trained: PO60min=PO20min × 0.95; trained: PO60min=PO20min × 0.92 and recreationally trained: PO60min=PO20min × 0.88. The predictions of the original equation and our model were assessed using the remaining third of the data. The predictive performance of the updated equation was better (original: R2=0.51, mean absolute error=27 W, mean bias=–12 W; updated: R2=0.54, mean absolute error=25 W, mean bias=–7 W). info:eu-repo/semantics/closedAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 2.0 2023 SPORT SCIENCES 53 / 127 = 0.417 2023 Q2 T2 0.73 2023 Orthopedics and Sports Medicine 2023 Q2 Physical Therapy, Sports Therapy and Rehabilitation 2023 Q2 Sports Science 2023 Q3 4.8 2023 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Cirer-Sastre, Rafel López-Laval, Isaac Universidad de Zaragoza (orcid)0000-0002-9304-3709 1006 245 Universidad de Zaragoza Dpto.
