| Abstract The study and analysis of the game has a big role for the coaches and athletes to find out the pros and cons of the team or athletes, and it is accurate effective measurement method. The analysis of game from Biomechanic side depended on one variable or several variables help to reach to accurate objective results can be used to explain the reasons of winning and losing in ground tennis game, the server tries to play the ball near the half way line or on the two sides of the serve area but in the front and back and different strikes, the athlete tries to return the ball to depth of the stadium and near side lines. Tennis game needs a high physical effort and accuracy in performing the skills. It is possible to get direct point through the serve or point through deducting mutual strikes ( the rally) by the front, back and other strikes. The mutual strikes are one of the factors that straining the athlete if they repeat at each point of the one round points as up to more than ( 10) strikes sometimes, then the point deducting according to the distance of the ball falling in the deep of the stadium and near side lines or near the net. During following up the world games of the ground tennis, the researcher observes that the falling of the ball during the serve performing and mutual strikes (rally) plays a great role in getting direct point in the serve, and straining competitor in mutual strikes by playing the ball on both sides ( right and left) of the stadium. Therefore the researcher aims to find out the distance of the falling of the ball in the half way line and both sides of direct and effective serve point. In addition to find out the distance of the falling of the ball at both sides of the stadium for deducting point in mutual strikes. The researcher uses descriptive method to solve the research problem . The research sample includes two female athletes ( Serena Williams and Maria Sharapova ) . The researcher concludes that Serena has won (28) points in direct in the two groups: (6) direct and effective serve points in the first group while (22) points in the second group, with a mean of both group reached (0.39) cm from the serve area lines which helps her to win the second group in the differences of the serves, while Serena has achieved (39) points in the two groups through mutual strikes :(19) points in the first group and (20) in the second group with a mean of the two groups reached (1.44) meters from the side lines of the stadium which helps her to win in the first group in the differences of mutual strikes. | ||
