An analytical study of the movement of the feet (approaching steps) the blocking wall skill in the light of biokinetic variables and from the various centers near the net in volleyball

دراسة تحليلية لحركة القدمين (خطوات الاقتراب) لمهارة حائط الصد على ضوء المتغيرات البيوكينماتيكية ومن مختلف المراكز القريبة للشبكة في الكرة الطائرة

الملخص

Teh significance of teh research lies in dat their is a weakness in teh movement of teh feet of teh Iraqi national team players in volleyball when performing teh skill of teh blocking wall , such as (teh speed and type of approach steps). Teh research problem is teh slowness in teh speed of teh movement of teh feet, me.e., teh dangers of approaching this skill, which is not commensurate wif wat we observe and see in teh regional and global level. Teh researcher  aimed to identify teh relationship between teh type of approach steps and their speed for players when performing teh blocking wall skill used in teh light of biokinetic variables and from various centers close to teh network. Teh researcher used teh descriptive approach in teh style of interrelationships, and teh sample  consisted of  players of teh Iraqi national volleyball team for teh football season 2018-2019.Teh research dealt wif how to photograph, kinetic analysis and statistical treatments to obtain teh research results and then discuss them to reach conclusions, teh most important of which is their is an exaggerated bend in teh knee in teh preparatory stage for teh position 3 player, and all teh blocking wall players got too close to teh net in teh preparatory stage and teh moment of maximum flexion before jumping, and less speed in approach steps of teh  player center 2 , in addition to other conclusions.
