The study aimed to design three-dimensional models based on biomechanical analysis and monitor its impact on the performance level of Overhead Serve skill in volleyball. the researcher used the experimental method by the experimental design of two groups (experimental and controlled group), The study was conducted on a sample of (50) female pupils from the preparatory stage in Cairo in 2018/2019. The most important results indicated that 3D models based on biomechanical analysis led to higher performance skill of Overhead Serve in volleyball compared to the traditional program.for female preparatory pupils.
