Resumen

En este estudio piloto se analizan algunas de las variables cinéticas y cinemáticas que pueden afectar a la situación de ejecución/evaluación del Press de Banca, en máquina Smith (PMS) vs con barra y discos (PBL). Dos sujetos entrenados participaron en esta investigación habiendo sido informados previamente de la finalidad de la misma. En dos momentos se llevó a cabo un protocolo incremental de cargas hasta alcanzar su máximo peso a desplazar en una repetición (1-RM), uno para el PMS y otro para el PBL. El Sujeto 1 (S-1) manifestó valores de fuerza de 770 y 837 N, en PBL y PMS, alcanzando este pico máximo de fuerza (PMF) a los 28 y 12 ms, respectivamente. En el caso del Sujeto 2 (S-2), los valores de PMF fueron de 693 y 849 N, empleando un tiempo en alcanzar estos PMF fue de 60 y 66 ms, en PBL y PMS, respectivamente. Se realizó un análisis detallado de las curvas de "sticking period", las distancias de agarre e inclinación de la barra. Como conclusión más relevante de nuestro trabajo y como base para futuras investigaciones, decir que a la hora de entrenar, el ejercicio en PBL puede ser más aconsejado. Mientras que para evaluar, el ejercicio en PMS aporta información más fiable en cuanto a las variables relevantes de la fuerza.
