highly accomplished Physical Education Teacher, Researcher, and Elite Coach based in Tunisia. With a specialized focus on Biomechanics and Para-Athletics. Cerebral Palsy (CP) involves permanent motor and posture development disorders. While strength and power are critical for athletic performance in sports like the shot put, there is currently a lack of validated testing protocols specifically for the upper limbs of seated Paralympic throwers (Classes F31-F34). This research aims to: Validate Assessment Tools: Establish the reliability of the Modified Push-Up (MPUS) and Modified Pull-Up (MPUL) tests for this specific population. Innovate Testing: Develop and validate a new Medicine Ball Throw test as a sport-specific measure of power.
