This study aims to use squat exercises in order to find out their effect on some physical variables of the lower extremity represented in (muscular strength of the legs) and flexibility represented in (extension of the instep - grip of the instep - angle of extension of the right knee - angle of bending the right knee - angle of extension of the left knee - Left knee flexion angle - hip joint flexibility), the technical level of the kutami nokata (Usai waza - shimi waza - kensetsu waza - salutations and movements), the percentages of improvement in the physical variables of the lower extremity (under research) and the technical level of the kutami nukata (under research), The research sample was chosen in a deliberate way from the players registered for the promotion test for the black belt (2) Those who are registered in the Egyptian Federation of Aikido, Sumo and Judo from clubs (Al-Shams - Heliopolis - Al-Nasr - Al-Zohour - Hololido - Fishing - Police Union) in Cairo Governorate and clubs (Jadela - Samad Talkha - Al-Jawwar - Al-Sinbilaween - Al-Manshiya) in Dakahlia Governorate and (Al-Rowad) Club in Sharkia Governorate and (Al-Fath) Club ) in Alexandria Governorate, and the number of the research community reached (27) players, and (2) players were excluded due to their old age (37, 50) years in order to achieve the homogeneity of the research community, then the researcher pulled (5) players in a random way as a pilot sample, and thus The number of the basic research sample has become (20) players Dan for the year 2021 ADThe researcher used the experimental method for one experimental group with a tribal and dimensional measurement for its relevance to the nature of this study, and she found that the proposed squat exercises had a positive impact on the strength and flexibility of the players' lower limbs, and also helped raise the level of technical performance of the players and improve the general physical condition and improve all elements. Physical activity, which increases the player's efficiency in performance, which is reflected in the technical level of the kata (Katami Nokata).
