Abstract
Con el objetivo de conocer la relación entre indicado-res biomecánicos y psicofisiológicos, así como las posi-bles diferencias psicofisiológicas pre-post y entre el uso o no de bastones con el rendimiento en las subidas en corredores de montaña, se realiza un estudio prospectivo y descriptivo de una carrera de montaña vertical. Para ello, se analizaron variables biomecánicas (velocidad, y manifestaciones de fuerza y potencia) y psicofisiológicas (lactato, frecuencia cardíaca y percepción subjetiva de fatiga) en un total de nueve (n = 9) corredores experimentados, divididos en dos grupos según su uso (n = 4) o no (n = 5) de bastones durante la carrera. Se realizan análisis no paramétricos para determinar las posibles relaciones entre variables, diferencias entre grupos y diferencias entre los valores psicofisiológicos previos y posteriores a la prueba. Los resultados no presentan diferencias ni correlaciones significativas (p <0.05) de re... In order to know the relationship between biomechanical and psychophysiological indicators, as well as the possible pre-post psychophysiological differences and the use of poles in the uphill performance on mountain runners, we performed a prospective and descriptive study of one vertical mountain race. Thus, it was analysed biomechanical (speed and strength/power manifestations) and psychophysiological variables (lactate, heart rate and subjective perception of fatigue) with a total of nine (n = 9) experienced runners divided into groups to use (n = 4) or not (n = 5) poles during the race. Nonparametric analyses were performed to observe the correlations between variables, the differences between groups and the differences between the psychophysiological values before and after the test. The results do not present significant (p < 0.05) differences or correlations of performance between those that used poles or not. There are significant differences between the psychophysiological var...
