اثر تمرينات التسهيلات العصبية العضلية ( PNF ) في النشاط الكهربائي ( EMG ) وبعض القابليات البيوحركية والمستوى الرقمي لذوي الاعاقة للرباعيين الشباب

The effect of neuromuscular facilitation (PNF) exercises on electrical activity (EMG) and some bio motor abilities and digital level for people with disabilities for young weightlifters

Abstract
The research problem centered on the lack of interest in using exercises for muscle sensory receptors (PNF). Because these exercises are of great importance in training, the researcher suggested the use of some exercises for the sensory muscular receptors to improve electrical activity and some biomotor abilities and improve the digital level for people with motor disabilities for young weightlifters
The research aims to:
– Preparing exercises for muscle sensory receptors (PNF).
– Identifying the effect of neuromuscular facilitation (PNF) exercises on electrical activity (EMG) and some biomotor
abilities and the digital level for people with disabilities for young weightlifters. The researcher used the experimental method in a one-group style with a pre and post measurement for its suitability to the nature of the research and to reach the goals. The research community and samples were chosen by the intentional method. They are handicapped (amputation in the lower right limb below the knee) and their number is (4) four quads who are
Homogeneous in the degree of injury (first degree A) according to the medical-technical divisions of the disabled with amputations, close in age and among the lifters committed to the exercises for the exploratory experience and the main experience.
The researcher used the PNF exercises prepared by him after conducting the pre-tests, and then conducted the post-tests of the sample for electrical activity (EMG) and some biokinetic abilities, and the digital level. After collecting and studying the results, he reached the most important conclusions:

Training using PNF neuromuscular facilitation exercises positively affected the electrical activity (EMG), some biomotor abilities, and the digital level of people with disabilities for the young weightlifters of the research sample.
After the results reached by the researcher, he recommends the following:
