Evaluation of central fatigue by the critical flicker fusion threshold in cyclists

Central fatigue related in sport stimuli wasstudied by Critical Flicker Fusion Threshold (CFFT) to know the influence of exercise on the central nervous system (CNS), but there is a lack of knowledge about the central or peripheral fatigue in endurance events. This study aimed to analyze changes in...

description Central fatigue related in sport stimuli wasstudied by Critical Flicker Fusion Threshold (CFFT) to know the influence of exercise on the central nervous system (CNS), but there is a lack of knowledge about the central or peripheral fatigue in endurance events. This study aimed to analyze changes in CFFT before and after the incremental cycle ergometer test as a means to assess the fatigue of the CNS. CFFT ascending and descending, the subjective criterion and sensory sensitivity were analysed in 8 professional male cyclists (72.1 ± 5.59 kg, 180.3 ± 6.43 cm, 17.4 ± 0.7 years) before and after a maximum incremental cycle ergometer test (start 50w increases 50w each 5 min). In this incremental test, the induced fatigue was probably more a peripheral phenomenon than one due to central nervous system fatigue, because sensory sensitivity did not significantly decrease. In conclusion, an incremental cycle ergometer test increased the cortical arousal and does not affect negatively the CNS of professional cyclists.

El objetivo de este estudio fue analizar los cambios en CFFT antes y después de la prueba de ergómetro de ciclo incremental como un medio para evaluar la fatiga del SNC. CFFT ascendente y descendente, el criterio subjetivo y la sensibilidad sensorial se analizaron en 8 ciclistas profesionales (72,1 ± 5,59 kg, 180,3 ± 6,43 cm, 17,4 ± 0,7 años) antes y después de una prueba de ergómetro de ciclo incremental máximo (50w de inicio aumenta 50w cada 5 min). En esta prueba incremental, la fatiga inducida fue probablemente más un fenómeno periférico que uno debido a la fatiga del sistema nervioso central, porque la sensibilidad sensorial no disminuyó significativamente. En conclusión, una prueba de ergómetro de ciclo incremental aumentó la activación cortical y no afecta negativamente el SNC de ciclistas profesionales.Clemente Suárez, Vicente Javier-0000-0002-2397-2801-600Diaz Manzano, Montaña-bd45ed23-7519-4d7b-a5a7-dff9b2fc8858-0engUniversidad De La CostaAttribution-NonCommercial-ShareAlike 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-sa/4.0/info:eu-repo/semantics/openAccesshttp://purl.org/coar/access_right/c_abf2Cortical arousalCentral nervous systemFatigueFlicker fusion thresholdCycle ergometerExcitación corticalSistema nervioso centralFatigaUmbral de fusión de parpadeoCicloergómetroEvaluation of central fatigue by the critical flicker fusion threshold in cyclistsEvaluación de la fatiga central por el umbral crítico de fusión de parpadeo en ciclistasArtículo de revistahttp://purl.org/coar/resource_type/c_6501http://purl.org/coar/resource_type/c_2df8fbb1Textinfo:eu-repo/semantics/articlehttp://purl.org/redcol/resource_type/ARTinfo:eu-repo/semantics/acceptedVersionBustamante-Sánchez, Á., Delgado-Terán, M., and ClementeSuárez, V.
