Abstract

This category of people with disabilities (CP38) is one of the categories that suffer from cerebral palsy (Cerebral Palsy), whether of the lower or upper limbs. This paralysis causes a disorder in movement and lack of control over body movements in terms of extending and flexing the working muscles and the assistance that the body needs in performance, whether for the upper limbs and lower limbs or the limb alone, and the focus is on the affected limbs that suffer from paralysis, and thus affects the strength and flexibility of the upper and lower limbs of the body.
The research aims to:
1- Develop proprioceptive neuromuscular (PNF) exercises using the reciprocal motor contraction (AR) method and the slow reciprocal motor contraction (SRHR) method to develop upper and lower limb strength and flexibility for 200m runners in the people with disabilities (CP38) category.
2- The effect of proprioceptive neuromuscular (PNF) exercises on developing strength, flexibility, and performance for 200m runners for people with disabilities (CP38) category.
Research hypotheses:

1. Proprioceptive muscle training (PNF) has a positive effect on developing strength and flexibility in upper and lower extremities, or the extremity alone, for people with disabilities in category (CP38).
2. Proprioceptive muscle training (PNF) has a positive effect on developing the 200m sprint performance of people with disabilities in category (CP38).

The researcher concluded the following:
1- Proprioceptive neuromuscular (PNF) exercises developed the strength and flexibility characteristics of the upper and lower extremities of 200m runners with disabilities (CP38) in the post-test.
2- Proprioceptive neuromuscular (PNF) exercises developed the achievement of 200m runners with disabilities (CP38) in the post-test.
The researcher recommends:

1. Continuing training curricula that will develop the upper and lower extremities in terms of flexibility and strength.
2. Developing more specialized exercises to develop flexibility and strength in the upper and lower extremities.
