دراسة تحليلية مقارنة لبعض المتغيرات البايوميكانيكية بين النزول إلى السجود على اليدين و الركبتين عند أداء فريضة الصلاة

Abstract EN

This study aims at : - Recognizing the values of some biokinematical and biokinetic variables of descending to prostration on hands and descending to prostration on knees .

- Recognizing the differences in the values of some biokinematical (instantaneous ) variables between descending to prostration on hands and descending to prostration on knees during prayer performance .

- Recognizing the differences in the values of some biokinematical (staging ) variables between descending to prostration on hands and descending to prostration on knees during prayer performance .

- Recognizing the differences in the values of some biokinetic ( staging) variables between descending to prostration on hands and descending to prostration on knees during prayer performance .

- The research sample was chosen deliberately from the Students of the college of Islamic Sciences and their number were (9) the camera replaced after (4.65m) and high (1.05m) to the left of the worshiper doing two movements and the speed of the camera 25 frames per second.s The researcher has concluded the following : - The significant differences achieved in the biomechanical variables related to the research were (12) significant differences from a base of (16) differences ,i.e.

at a rate 75% .

On the other hand, the significant differences achieved in the biokinematical variables (instantaneous ) were (5) significant differences from a base of (6) differences at a rate (83.33%) .

The significant differences achieved in the biokinematical variables (staging ) were (4) significant differences from a base of (7) differences at a rate (57.14%) .And, the significant differences achieved in the biokinetic variables (staging ) were (3) significant differences from a base of (3) differences at a rate (100%) .
