The researcher touched on the importance and the great role that the science of sports training plays in the development of sports activities in general on the physical level through scheduling special exercises with the addition of the weighting methods that were used, and also touched on the space occupied by the activity of ground tennis at the global level and the prominent and clear role it played Through the increasing number of followers and practitioners because of the high physical requirements necessary to carry out her beautiful skills, which took a large and wide public space for the strength of performance and competition witnessed by the event at the global level as well as the pleasure of watching and the abundance of material prizes enjoyed by the event, and the problem was identified for the group of Al-Fatwa players In Nineveh Governorate, aged (14-16) years for the season2019-2020 who are the research sample with a fixed level of performance and based on skill exercise, so the researcher deliberately developed a set of exercises similar to the case of playing with the use of a weight method according to the Fisher system, where weights were placed at (5% ) of the weight of the limb for the experimental group, while the control group followed A group of trainer exercises that depended on the skill exercise.

The study sought to identify: - Preparing special exercises using weights- Significance of statistical differences between the results of the two tests, pre and post tests in the strength characteristic of speed and velocity of the legs for tennis players 14-16 years and for the experimental and control groups.

The researcher made the following two hypotheses: - There are statistically significant differences between the results of the pre- and post-tests in the strength characteristic of speed and velocity of the two legs for tennis players 14-16 years old and for the experimental and control groups.

- There are statistically significant differences between the results of the post-tests in the strength characteristic of speed and velocity of the legs for tennis players 14-16 years and for the experimental and control groups
