Validity of a New Taekwondo-Specific Field Test in Sub-Elite Athletes

The purpose of this study is to find out whether a new taekwondo-specific field test (TSFT) is a valid way to measure the fitness of taekwondo athletes. The TSFT was designed to reflect what athletes actually do in competition: repeated, high-intensity kicks scored by an official electronic scoring system, with short rest periods in between. The main questions this study aims to answer are: * Is performance on the TSFT related to aerobic fitness (estimated VO2max) measured with the 30-15 Intermittent Fitness Test? * Is performance on the TSFT related to anaerobic performance and fatigue tolerance measured with the Wingate Anaerobic Test? Male sub-elite taekwondo athletes completed the new TSFT and two widely used reference tests (the 30-15 Intermittent Fitness Test and the Wingate Anaerobic Test). Researchers then compared the results of the new test with those of the reference tests.

Inclusion Criteria: * Male taekwondo athletes classified as sub-elite (continuous participation in regional and national competitions) * Regular systematic training of at least 3 sessions per week * Active competitive status during the study period * Free from injury Exclusion Criteria: \- Any current injury or health condition preventing maximal-effort exercise
