squat traning effect on lower limb strength and flexibility and Katame Nokata Technical Performance

Squat exercises and their effect on lower limb strength and flexibility and the level of technical performance
For the lactami nocata
This study aims to use squat exercises in order to know their effect on:
1- Some physical variables of the lower limb represented in (the muscle strength of the two legs) and flexibility represented in (metatarsal extension - metatarsal grip - right knee extension angle - right knee bend angle - left knee extension angle - left knee flexion angle - hip joint flexibility)
2- The technical level of the katami nukata represented in (ossai waza - chimi waza - kensso waza - greetings and moves)
3- Improvement rates in the physical variables of the lower limb (under discussion) and the technical level of katami nuccata (under investigation)
The researcher used the experimental approach of one experimental group with a pre-post measurement due to its relevance to the nature of this study
The research sample was deliberately chosen from the players registered for the promotion test for the black belt (2 Dan) for the year 2021
the researcher reached the following conclusions:
• The proposed Squat training positively affected the strength and flexibility of the lower limb of the players.
• Squat training helps to raise the technical performance of the players.
• Squat exercises contribute to improving the general physical condition and improving all physical elements, which increases the player's efficiency in performance.
