Abstract
[Resumen] : El propósito del presente trabajo fue valorar el efecto agudo del entrenamiento de fuerza explosiva sobre el rendimiento mecánico. De una muestra de 9 sujetos masculinos se obtuvo la máxima carga movilizable en una sola repetición concéntrica (1RM) del ejercicio press banca y la resistencia correspondiente al máximo nivel de potencia. Posteriormente se desarrollaron dos sesiones consistentes en 7 series de 3 repeticiones con las cargas asociadas a la máxima potencia individual. Previo a la primera serie de entrenamiento e inmediatamente posterior a la última se obtuvieron los niveles de potencia desarrollados tanto con el 90% 1RM como con la magnitud manejada en la sesión. Finalmente se llevó a cabo una evaluación postest. El ANOVA para medidas repetidas reflejó diferencias significativas al 90% 1RM (p<0.05) aunque los contrastes de los valores previos y posteriores a cada una de las sesiones no alcanzó significación estadística (p>0.005) en ninguna de las variables. No se detectó asociación estadísticamente significativa entre las modificaciones agudas del rendimiento y el nivel de fuerza de los sujetos. Sin embargo, si se halló correlación significativa (p<0.05) entre éste parámetro en el postest y el porcentaje de 1RM que suponía la carga de máxima potencia en la última medición.
[Abstract] : The purpose of this study was to measure the acute effect of two explosive strength sessions on mechanical performance. In order to do that, 1 repetition maximum and maximum power load were obtained in 9 men. The experimental procedure begun five days after and it involved two training sessions. 7 bouts of 3 repetitions at maximum power load of bench press were developed in every session with a minimum rest period of three minutes. Power developed at 90% 1RM and at maximum power load were measured before and after every training day. Finally it was carried out a postest measuring. Although repeted-measures ANOVA showed significant differences between measurements at 90% 1RM , statistics analysis did not show significant differences regarding to before-after every sessions contrasts, and between measuring at maximum power load. Also, we did not find significant 1RM correlation with performance differences before-after session. Finally, it was found significant correlation between maximum strength and % 1RM associated to developed maximum power at postest.
