Effect of some resistance techniques methods on the level of muscular ability and the accuracy of directing the straight serve for tennis juniors

The study aims to identify Effect of some resistance techniques methods on the level of muscular ability and the accuracy of directing the straight serve for tennis juniors.
The researcher used the experimental approach by applying the proposed training program to tennis juniors, by designing two equal groups, the first experimental and the second controlling, using the method of pre and post measurements, as it is considered appropriate to achieve the objectives and hypotheses of the research.
The research sample was chosen in a deliberate way from the tennis juniors in the tennis complex in the Olympic Village for the age group under 14 years, and the research sample amounted to ( 32) juniors, they were divided into 11 juniors as an experimental sample, 11 juniors as a control sample and 10 juniors as an exploratory sample, then the researcher performed homogeneity And the equivalence of the research sample, then the application of the program, which contained some resistance techniques methods training for 9 consecutive weeks, and it consisted of 32 training units, 4 training units per week.
After completing the applying of some resistance techniques methods training program, dimensional measurements were taken, the data was processed statistically, and the results were presented and discussed.
The researcher using some resistance techniques methods in tennis juniors’ programs.
The researchers recommend the use of some resistance techniques methods in tennis juniors training programs.
