在柔道地面制敵法裡面，大部分的動作都是從柔術上的技術去做改良，柔術裡的關節技可以對腳踝關節、腳關節這些部位做攻擊，柔道為了發展成現代運動，因此才制定了規則，將較有殺傷力的柔術技術動作給捨去掉，只能對手肘關節去施技！1882年由日本嘉納治五郎先生所創立的武術運動，並且以『精力善用』、『自他共榮』作為柔道運動的宗旨，在嘉納治五郎先生的推廣下，柔道項目在1964年東京奧運會之後被列為奧運的正式比賽項目，柔道主要分為立技跟寢技，這兩種方式來獲得分數，這是一項需要肢體對抗以及細膩技術的技擊運動，不只需要強壯的身體條件以及熟練的技術動作，更是需要具備良好的心理素質，筆者在選手時期，除了常見的立技得分之外，再來就是以關節技得分獲勝居多，基此原因，筆者撰寫本『柔道-十字關節技應用』技術報告書，將以自己的實戰經驗與運動科學理論相互配合，作為撰寫方式。藉由此技術報告書，提供柔道運動愛好者有所參考依據。
In Judo Katame-waza, most of the movements are derived and improved from Jujutsu techniques, where Jujutsu Kansetsu-waza can be used to attack joints of the ankle and foot. To develop Judo as a modern sport, the more lethal techniques of Jujutsu were abandoned when the rules were drawn up, only the joints of the elbow can be used to perform the techniques! The martial arts movement founded by Mr Jigoro Kano in 1882 is based on the principles of seiryoku zen'yo and jita kyoei. After the Tokyo 1964 Olympic Games, Judo was classified as an official Olympic sport at the initiative of Mr Jigoro Kano. There are two main types of Judo, Tachi-waza and Ne-waza, used to score points. It is a combat sport that requires physical confrontation and technical finesse, not only in terms of physical conditioning and technical skill but also in terms of mental strength. In my time as an athlete, most of the points were scored with Kansetsu-waza, apart from the usual Tachi-waza. For this reason, I have written this technical report on “Judo - application of Juji-Gatame” based on my practical experience and sports science theory. Through this technical report, I hope to provide a reference for Judo enthusiasts.
