摘要

目的：分析2010年及2012年空手道選手在世界級比賽中道服與護具調整次數、間隔時間及比賽總時間，以瞭解世界空手道聯盟2011年新規則（如增戴身體護具、不進行延長賽、增加消極犯規等）對選手調整道服與護具次數及比賽總時間之影響。方法：以2010年及2012年世界空手道錦標賽男女對打各量級前五名選手作為研究對象，使用官方影片進行影像分析，記錄道服與護具調整次數與其間隔時間、比賽總時間。結果：道服與護具總平均調整次數2012年（男：31.93次；女：22.43次）高於2010年（男：21.33次；女：15.57次）；平均調整間隔時間2012年（男：7.52秒；女：8.03秒）頻繁於2010年（男：11.25秒；女：11.56秒）；平均比賽總時間2012年（男：6分11秒；女：4分47秒）長於2010年（男：5分31秒；女：4分11秒）。相較於2010年，2012年男子組每場平均調整身體護具、道服、腰帶、拳套、護脛、護腳背次數分別增加1.20次、2.15次、1.93次、3.46次、1.69次、0.70次；女子組分別增加1.86次、0.57次、1.29次、3.36次、0.07次、0.86次。結論：增戴身體護具規定實施後可能增加道服與護具調整次數及比賽總時間。相較於2010年，2012年世界空手道錦標賽有較多的道服與護具調整次數，較短的調整間隔時間，以及較長的比賽總時間。
