This result cannot be obtained unless the player adjusts the starting steps and preparing to jump. The kinetic momentum that the player receives as a result of the starting steps (moves) is equal to the kinetic impulse of the player according to the law kinetic momentum. As we see during the game. Part of the player perform the skill of spike with one step than jump and there are some players perform the spike with two or three steps depending on the distance and the height of the ball. The aim of the research is to compare between the first step, second and third steps of the Approach stage in some biomechanical variables in the performance of the skill of spike, Ten players representing the university's volleyball team were selected, The researcher used the coefficient of variation of the physical variables range between(6.2 8.8%), The analysis was performed by means of a special device (jump ma...

In addition to that, the research aimed at identifying the relationship between the mechanical, motor, and potential energy values, kinematical variables, scoring accuracy indicator values in youth soccer players. The researcher used the descriptive method on (7) youth players from Newroz youth soccer club. He used (2) specialized video cameras for analyses and programing using Kinovea. He also conducted scoring accuracy to collect the data that was treated using SPSS. Five views were used from a total of six makings (35) for analyzing mechanical variables and scoring accuracy to conclude a relationship between mechanical, motor, and potential energy with many variables. Finally, he recommended that coaches should pay attention to mechanical and motion energy for their direct relationship with working mu...
