Aerobic-Anaerobic Fitness Levels and the Consistency of Roundhouse Kick Performance During Multi-Round Taekwondo Matches Among Taekwondo Athletes

Abstract

This study examined the relationship between self-assessed aerobic-anaerobic fitness levels and roundhouse kick performance consistency during multi-round taekwondo matches among athletes at Jiaozuo University, China. A descriptive-comparative-correlational design was employed, with data collected via a validated self-assessment questionnaire administered to 100 taekwondo athletes. Results indicated moderate overall fitness levels (composite mean = 2.18, SD = 0.78), with power output under fatigue perceived as the strongest component (mean = 2.24, SD = 0.82) and speed recovery between exchanges as the weakest (mean = 2.14, SD = 0.79). No statistically significant differences were found across demographic factors (age, sex, years of experience), though trends suggested higher self-perceptions among mid-adolescent athletes and those with 3–5 years of training experience. The findings highlight the need for integrated conditioning programs that target recovery capacity, endurance sustainability, and sport-specific neuromuscular adaptation to maintain kick consistency under fatigue.
