Relationships between sport-specific tests and their validity in predicting the time-motion profile in international taekwondo matches

The pattern of correlations emerged between sport-specific performances suggests that the dynamics of interaction between anaerobic and aerobic metabolism are crucial for maintaining the short and intermittent kicking actions. The rhythm of the first combat of the day, generated by the technical-tactical dynamics, justifies the inability to predict high- and low-intensity actions from the physical fitness variables. However, both the time-motion indexes and tests' performance allow for the prescription of specific trainings. Time-motion indexes could be used to structure sport-specific high-intensity interval training (HIIT), while the ten seconds FSKT performance and the capacity and power indicators of the PSTT (i.e., kick frequency at the heart rate deflection point and maximal kick frequency, respectively) could be used to prescribe HIIT with short and long intervals.
