This research aims to improve the technical performance of the pushing move (upgrading) for performing the smash hit through: identifying the topography of the force of the pushing move (upgrading), identifying the speed of growth of the force in the time of the pushing move (upgrading), identifying the most effective muscles on the speed of growth of the force in the time of the performing the pushing move (upgrading) in the smash hit. The researcher used the descriptive approach with a sample consisted if four high level female volleyball players, each one had (2) attempts, thus the research sample included (8) attempts. The performance of the players were filmed and analyzed via the Force Platform, Electromyography device (EMG 16 Chanel Wireless). The following results were concluded: the correlation coefficient between the speed of the growth of force and the average electrical activity of the pushing move (upgrading) for the smash hit was that the brachial biceps, latissimus dorsi muscle, rectus abdominis muscle, medial vastus quadriceps, right semitendinosus muscle, left femoral quadriceps, left semitendinosus muscle are the fastest shrinking muscles and the most effective and relative to the speed of growth of the force. There was also a negative correlation between the variables of the time of the ultimate force and the speed of growth of the force, and a positive correlation between the variables of the ultimate force at the moment of pushing and the speed of growth of the force. The most effective muscles on the speed of growth of the force for the movement of upgrading (pushing) in smash hit: the medial vastus quadriceps, left femoral quadriceps, and left semitendinosus muscle.
