ABSTRACT

Las transiciones en triatlón afectan al rendimiento y riesgo de lesión. El objetivo fue determinar la fatiga neuromuscular inducida por 40 km de ciclismo y la eficacia del entrenamiento pliométrico en la fatiga y rendimiento de la carrera a pie. Participaron doce triatletas, 5 realizaron un entrenamiento pliométrico y 7 continuaron su entrenamiento habitual. Se realizaron tests de salto antes y después de 40 km de ciclismo para determinar la fatiga y se registró el ritmo de 5 km de carrera. Se observaron diferencias significativas en la altura de salto (p < 0,05) indicando que 40 km de ciclismo inducen fatiga en la extremidad inferior. Tras el entrenamiento pliométrico se observaron mejoras significativas en el test Squat Jump posterior al ciclismo (p = 0,038) y en el ritmo del primer kilómetro (p = 0,015). El entrenamiento pliométrico parece ser más eficaz que el entrenamiento habitual para mejorar la fatiga neuromuscular y el ritmo del primer kilómetro


The transition between the different phases of triathlon affects both athletic performance and risk of injury. The aim was to determine the neuromuscular fatigue induced by 40 km cycling and the plyometric training efficacy in order to improve such fatigue and running performance. Twelve triathletes participated, 5 of them did specific plyometric training versus 7 who continued with their usual training. Different jump tests were carried out before and after 40 km cycling in order to determine the fatigue, the 5km-running pace was also recorded. Significant differences were observed in the jump height (p < 0,05) post-cycling, showing that 40 km cycling induces leg neuromuscular fatigue. After the plyometric training, significant improves were observed in the Squat Jump Test post-cycling (p = 0,038) and in the first kilometre running pace (p = 0,015). The plyometric training seems to be more effective than usual training to improve cycling induced neuromuscular fatigue and the first kilometre running pace
