Programs and applications for the kinematic analysis of the human body are many and varied, and they all share one goal, which is to reach correct results for the biomechanical variables of human movement, whether in life or in sports, but these programs differ in the way they work, although the basics are the same, all of them extract three basic variables: distance, time, angle, and possible To be added to it by information by the user of the program, such as the player's mass, the longest parts of the body, age, total height, etc., and its purpose is to extract additional variables by providing the program with laws. All this is reflected in the researcher in choosing the appropriate program for him in terms of application, method of use and the results he wants to obtain.
Yasir NAJAH Hussein , concerning the kinematics analysis, i suggest you to follow the ISB recommandation for segmental frame definition [1,2,3,4]. It permits to compute articular kinematics. They are more complicated to implement than segmental kinematics but those are more repeatible from a study to another.
To the software point of view, it is quite common now to compute articular kinematics through multi-Body kinematics Optimization algorithm with OpenSim [5,6] or Anybody.
OpenSim is freely available.
I showed an example in golf biomechanics in 2018 [7], with a focus on the shoulder which is often roughly detailed in sport biomechanics.
Based on articular kinematics, and segmental kinematics you can compute all the parameters you want (geometry, kinematics, kinetics and forces and dynamics if you also measure ground reaction force)
I hope this would help
