摘要

Background and Purpose: Poomsae is a set of defined defense-and-attack poses to show Taekwondo skills. Kumgang is the most difficult set due to multiple stability-demanding ＂crane-stance＂ (single-leg stance) poses. Kinesio taping (KT) is widely used in sport to improve performance or prevent injury, thus might benefit Poomsae athletes. Therefore, we investigated the effect of KT on postural stability during single-leg stance in Poomsae athletes. Methods: Thirteen athletes were recruited and performed Kumgang with and without KT applied over bilateral knee joints. Joint angles and plantar pressure distribution were measured to evaluate the postural stability during the crane-stance poses. A crane-stance pose included a dynamic phase and a static phase. The dynamic phase featured the transition from double-leg stance to single-leg stance and turning body 90 degrees on the supporting leg. The static phase featured the maintenance of a steady single-leg stance. Paired t-test was used to investigate the effect of KT on joint angles and plantar pressure distribution during the crane-stance pose. Results: The traveling distance of the center-of-pressure (COP) during the dynamic phase was significantly correlated with the sway area of COP during the static phase (r = 0.68, p ＜ 0.01). In the dynamic phase, knee KT showed a lower COP traveling distance than the no- KT condition (KT: 6.2 ± 4.0 cm, no-KT: 8.8 ± 4.5 cm, p = 0.04), and no differences were found in joint kinematics. In the static phase, knee KT showed a smaller COP sway area (KT: 8.2 ± 5.7 cm^2, no-KT: 11.6 ± 5.1 cm^2, p = 0.02) and greater mean knee flexion (KT: 61.0 ± 7.2°, no-KT: 56.2 ± 6.3°, p = 0.01) than the no-KT condition. Conclusions: Our results showed that a shorter weight shift distance in the dynamic phase reduced the magnitude of postural sway in the static phase during the crane-stance pose. Furthermore, bilateral knee KT improved postural stability in both static and dynamic phases, probably by lowering body mass via increased knee flexion. Clinical Relevance: This study offers Taekwondo coaches and athletes an important insight into the effect of KT and the strategy to improve Poomsae performance.
