espanolLos deportistas que participan en el Rally-raid Dakar deben mostrar su competencia para dar respuesta a un esfuerzo de larga duracion en el que intervienen factores limitantes de caracter psicologico y fisiologico por la fatiga acumulada durante el esfuerzo. El objetivo de esta investigacion fue analizar la idoneidad de diferentes instrumentos de evaluacion de la percepcion de fatiga de motoristas en competicion. El diseno de investigacion es de caso unico, con un participante (motorista). El estudio consistio en la realizacion de dos sesiones de entrenamiento que se desarrollaron en un circuito simulando las condiciones de distancia y dificultad propias de una etapa. Los instrumentos de registro fueron el cuestionario POMS (McNair, Lorr y Droppleman, 1971), la escala RPE-Borg (Borg, 1982), para el registro de la percepcion del esfuerzo realizado y las escalas EVA-fatiga (Lee, Hicks y Nino, 1991) y SEES (McAuley y Courneya, 1994) para valorar la percepcion de fatiga. En el apartado de resultados y discusion, se analizan los datos obtenidos, estableciendo diversas conclusiones en relacion al objetivo planteado; viendo que el cuestionario POMS resulto valido y sensible, las escalas EVA-fatiga, RPE y SEES-fatiga cumplieron los requisitos de facilidad de uso, validez y sensibilidad al trabajo efectuado. EnglishAthletes participating in the Rally-raid Dakar must show their competence to respond to a long-term effort in­volving psychological and physiological limiting factors due to the accumulated fatigue during the effort. The objective of this research was to analyze the suitability of different instruments to evaluate the fatigue perception of motorcyclists in competition. The research design is single case, with one participant (motorcyclist). The study consisted of two training sessions that were devel­oped in a circuit simulating the conditions of distance and difficulty of a stage. The instruments were the POMS questionnaire (McNair et al., 1971), the RPE-Borg scale (Borg, 1982) for the re­cording of perceived effort, VAS-fatigue scale (Lee et al., 1991), and SEES (McAuley & Cour­neya, 1994) for assessing the fatigue perception. In the results and discussion section, we analyze the data ob­tained, establishing different conclusions in relation to the objective set. The POMS questionnaire was valid and sensitive, the VAS-fatigue, RPE and SEES-fatigue scales met the ease of use, validity and sensitivity requirements to the study performed.
