Effects of Taekwondo Match-Simulated Fatigue on Balance Performance in Female Athletes

Starting soon · Not applicable

Conditions studied: Taekwondo Match-simulated Fatigue, Static Balance, Dinamic Balance, Female Athletes, Postural Balance, Fatigue

In brief

Taekwondo is a high-intensity combat sport characterized by repeated explosive kicking actions and rapid changes in body position, requiring well-developed postural control to maintain technical performance and reduce injury risk. Although fatigue has been reported to impair balance performance, previous studies have primarily induced fatigue using non-specific laboratory protocols that do not adequately reflect the physiological and neuromuscular demands of taekwondo competition. Consequently, the effects of taekwondo-specific fatigue on static and dynamic balance performance remain insufficiently understood. The primary objective of this study will be to investigate the effects of a taekwondo match-simulated fatigue protocol on static and dynamic balance performance in female taekwondo athletes. Eighteen competitive female taekwondo athletes will participate in this single-group repeated-measures study. Following a familiarization session, participants will complete a standardized taekwondo match-simulated fatigue protocol consisting of three 2-minute rounds separated by 1-minute passive recovery periods, replicating the official Olympic competition format. Static and dynamic balance performance will be assessed before and immediately after the fatigue protocol using the Biodex Balance System (Biodex Medical Systems Inc., Shirley, NY, USA). Balance performance will be evaluated under static and dynamic testing conditions, and the Overall Stability Index, Anteroposterior Stability Index, and Mediolateral Stability Index will be recorded. The findings of this study are expected to improve understanding of the acute effects of sport-specific fatigue on postural control in female taekwondo athletes and may contribute to the development of evidence-based training and injury prevention strategies.
