Abstract

The aim of this study was to analyse the relationship between External Load (EL) and internal load (IL). Thirteen male basketball players competing at professional level in First Spanish Division (ACB) during six friendly games throughout the 2020/2021 preseason were monitored. The EL variables collected were movement load (ML), movement intensity (MI), box score time (BST), and total duration (TD)] while IL variables monitored were heart rate (HR), respiratory rate (RR), training impulse (TRIMP) and time invested in five HR zones. Very large to almost perfect correlation (r= 0.77-0.91) exists between EL variables except TD. In addition, HR, TRIMP and RR present large to very large correlation (r= 0.55-0.79) with all EL variables except TD. Monitoring HR-based variables would present general information and an estimated prediction of players EL which could allow basketball practitioners to prioritize time invested players internal/external load.

Keywords: Training load; load monitoring; heart rate; TRIMP

Resumen

El objeto de este estudio fue analizar la relación entre la Carga Externa (EL) y la Carga Interna (IL) durante partidos de baloncesto. Trece jugadores profesionales de la primera división Española(ACB) fueron monitorizados durante 6 partidos amistosos a lo largo de la pretemporada 2020/2021. Las variables de carga externa recogidas fueron carga de movimiento (ML) intensidad de movimiento (MI), tiempo de marcador (BST) y duración total (TD), mientras que las variables de carga interna monitorizadas fueron Frecuencia Cardíaca (HR), Frecuencia Respiratoria (RR), Impulso de Entrenamiento (TRIMP) tiempo invertido en cinco zonas cardíacas. Existe una alta correlación a casi perfecta (r= 0.77-0.91) entre las variables de EL except TD. Además, HR, TRIMP y RR presentan una alta a muy alta correlación (r= 0.55-0.79) con todas las variables de EL excepto TD. Monitorizar variables basadas en el HR puede aportar información general y estimar una predicción de la EL de los jugadores, lo que podría ayudar a los profesionales a priorizar el tiempo invertido en monitorizar la carga interna/externa.

Palabras Clave: carga de entrenamiento; monitorización de la carga; frecuencia cardíaca; TRIMP
