Power-Load Curves in an Elite Weightlifter. A Case Study. [Curvas de carga-potencia en un halterófilo de élite. Estudio de caso].

Abstract

Abstract

Findings from mechanical power data can make a significant difference in the performance of athletes in weightlifting if it is properly understood by coaches. The purpose of this study was to examine the power-load (P-L) curve in the snatch, clean, back jerk and jerk of an international-level Spanish weightlifter. Four testing sessions were conducted in the present work. Session 1: estimating snatch and clean 1RM (1 repetition maximum); Session 2: power assessment of the snatch and clean across a spectrum of loads (30% to 100%) of the predetermined 1RM; Session 3: estimating back jerk and jerk 1RM; Session 4: power assessment of the back jerk and jerk across a spectrum of loads (30% to 100%) of the predetermined 1RM. The highest peak power output (Pmax) was reached with loads of 90% of 1RM in each exercise tested, which demonstrated this percentage to be the optimal load (Pmax load) to train power development during weightlifting exercises.

Resumen

El entendimiento por parte de los entrenadores de los datos de potencia mecánica obtenidos en la halterofilia puede marcar notables diferencias en el rendimiento de los atletas. El propósito de este estudio fue examinar la curva de carga-potencia en los ejercicios de arrancada, cargada, envión por detrás y envión en un halterófilo español de nivel internacional. Cuatro sesiones de evaluación fueron llevadas a cabo en este estudio. En la sesión 1 se estimó el 1RM (1 repetición máxima) en la arrancada y la cargada. En la sesión 2 se realizó una evaluación de la potencia alcanzada en la arrancada y la cargada en un espectro de cargas desde el 30% al 100% del 1RM predeterminado anteriormente.  En la sesión 3 se estimó el 1RM en el envión por detrás y el envión. En la sesión 4 se realizó una evaluación de la potencia alcanzada en el envión por detrás y el envión en un espectro de cargas desde el 30% al 100% del 1RM predeterminado anteriormente. El pico de potencia mecánica fue alcanzado con el 90% del 1RM en cada uno de los ejercicios, mostrando dicho porcentaje como la carga óptima para el desarrollo de la potencia en ejercicios de halterofilia.
