Resumen
Las pruebas de piragüismo slalom son caracterizadas por descensos de alta intensidad en
ríos y correderas. Valores elevados de frecuencia cardíaca (FC) son observados en la
modalidad. Sin embargo, datos acerca de la variabilidad de FC (VFC) y efectos del
entrenamiento sobre ese parámetro todavía no fueron investigados. De ese modo, el
objetivo del estudio fue analizar a partir de la VFC de canoeros slalom, los efectos de siete
semanas de entrenamiento monitoreado sobre la modulación autonómica de la FC. Fueron
evaluados seis canoeros antes y después del entrenamiento. La FC e intervalos R-R fueron
captados por 15 min, con atletas en reposo en la postura sentada. La VFC fue analizada en
el dominio del tiempo. El entrenamiento fue realizado en seis sesiones semanales de
aproximadamente 2 hs/día. Los valores obtenidos muestran un predominio parasimpático
en la modulación de FC de los canoeros sin diferencias significantes entre los índices de la
VFC. El monitoreo reveló que la 3ª semana presentó valores superiores siendo la VFC no
alterada en ese período. De acuerdo con los resultados, el grupo de canoeros slalom
presenta predominancia parasimpática referente a la modulación autonómica de la FC, que
no es modificada tras siete semanas de entrenamiento.
