La incorporacion del trabajo con tecnologia isoinercial en los diferentes programas de entrenamiento ha contribuido a una notable mejora en el desarrollo de la fuerza y potencia muscular. Objetivos: evaluar la fuerza de la musculatura flexora y extensora de la rodilla en fase concentrica y excentrica. Metodo: durante 4 semanas (3 sesiones semanales) se ha realizado un programa de entrenamiento con tecnologia isoinercial con movimientos simultaneos de flexion y extension de rodilla de ambas extremidades. Antes y despues del programa de entrenamiento se ha evaluado la potencia del tren inferior a traves de la tecnologia isoinercial versapulley en ejecuciones separadas de extension y flexion de rodilla. Se ha obtenido y monitorizado datos de potencia, velocidad, fuerza, trabajo, tiempos de repeticiones,.., tanto en fase concentrica como excentrica. Resultados: se ha obtenido mejoras significativas (p<0,05) tanto en fase concentrica como excentrica en movimientos de flexion y extension de la rodilla. Conclusiones: durante las primeras etapas de la recuperacion funcional los ejercicios generales provocan adaptaciones entre extremidades y disminuyen la asimetria provocada por la lesion deportiva. En un proceso de recuperacion fisica disminuye la carga excesiva que provoca trabajar la extremidad por separado y en consecuencia disminuir el periodo de recuperacion. Abstrac : Training programmes incorporating isoinertial technology have contributed to a considerable improvement in developing muscle force and muscle power. Objectives: to evaluate knee flexor and extensor muscle force in concentric and eccentric contractions. Method: A 4-week training programme (3 sessions/week) using isoinertial technology was implemented, involving simultaneous flexion and extension of both knees. Before and after the training programme, lower-body power was evaluated using “VersaPulley” isoinertial technology in separate knee extension and flexion exercises. Data for power, velocity, force, work, repetition times etc. were recorded and monitored for both concentric and eccentric contractions. Results: Significant improvement (p=0.05) was recorded for both concentric and eccentric contractions in knee flexion and extension. Conclusions: In the early stages of functional recovery, general exercise enhances adaptation between limbs, reducing the asymmetry prompted by sports injuries. In the course of physical recovery, the overload caused by working separately with the affected limb is diminished, thus shortening recovery time.
