Resumen
Este estudio analizó las exigencias de carga interna (Frecuencia cardíaca, FC) y
externa (Velocidad; Player Load, PL; Power Metabolic, PM; Stiffness Vertical, Kvert;
entropía aproximada, ApEn) que se producen en función del desnivel del terreno en
una carrera de montaña. Un atleta de nivel nacional (edad: 25.3 años; altura: 172
cm; peso: 67 kg; VO2MAX: 70.2 ml/kg/min) participó en una prueba oficial (Distancia:
27.6 km; Desnivel acumulado: 973 m), analizado en 6 segmentos en función del
desnivel (sin desnivel, positivo y negativo). El registro de datos se realizó mediante
un dispositivo inercial WIMU PROTM (RealTrack Systems, Almería, España). Los
resultados muestran un aumento de PL/min y PM/min en desnivel negativo y de
FCAVG en desnivel positivo. Kvert y ApEn fueron más bajos en desnivel positivo,
mientras que la velocidad fue mayor sin desnivel. Se encuentra gran variabilidad en
las exigencias en función de la orografía del terreno, siendo importante su análisis
para el diseño específico del entrenamiento y la planificación del evento.
This study analysed the internal load (heart rate, HR) and external load demands (speed, Player Load, PL; Power Metabolic, PM; Vertical stiffness, Kvert; approximated entropy, ApEn) during a trail running race in relation to the slope. A national-level athlete (age: 25.3 years; height: 172 cm; weight: 67 kg; VO2MAX: 70.2 ml/kg/min) participated in an official race (Distance: 27.6 km; Accumulated slope: 973 m), analysed in 6 segments related to the slope (without, positive and negative slope). Data register was realised through an inertial device WIMU PROTM (RealTrack Systems, Almería, Spain). The results show an increase of PLT /min and PM/min in negative slope and an increase of HRAVG in positive slope. Kvert and ApEn were lower in positive slope, while velocity was faster without slope. It is found a great variability in the trail runner demands related to terrain orography, being important its analysis to design specific training sessions and race planning.
