Effects of two work-to-rest ratios on physiological, neuromuscular, and RPE responses during taekwondo-specific HIIT.

ABSTRACT:

Purpose

To investigate the effects of different work: rest (W: R) ratios on physiological, neuromuscular, and rating of perceived exertion (RPE) responses during taekwondo-specific high-intensity interval training (HIIT).

Methods

Thirteen moderate-trained taekwondo athletes completed a familiarization session and two HIIT trials which consisted of three rounds of 2 min roundhouse kicks with 1 min of rest in between. The W: R ratio protocols were: 1:0.5 (10s:5s) and 1:5 (10s:50s). Heart rate (HR) and oxygen uptake (VO₂) were continuously determined throughout the trials. Blood lactate concentration ([La^-]), countermovement jump (CMJ), and RPE were recorded before trials and after each round. The estimated contribution of the energy systems was calculated
