摘要：Aim. The purpose of this preliminary research was to determine the training model used, by measuring the anthropometric parameters and studying the specific means that were used in order to achieve the objectives. These were to mark the content of the physical preparation lessons in order to establish the intensity of the training, the number of repetitions, the frequency, the duration and the components of the of the training cycle. Another objective of the study was to see if there are any significant differences between the results of the boys in comparison to those of the girls. Methods. Twenty two romanian tennis players, eleven girls and eleven boys, between the ages of 14 to 16 years were part of this preliminary study. The group of tennis players were followed during 12 weeks of their usual physical trainning. At the end of this time period the following measures were conducted sprint 5-10 m, 30 m run, 6 times 20 m, long jump, successive lateral jumps performed on both legs over the gym bench, medicine ball throw from the spot with one hand, overhead medicine ball throw test, added step, hexagon test, planned agility test and push ups. Depedding on the test, they were measured by time in seconds, number of repetitions or length in cm. Results. The group of tennis players were followed during 12 weeks of their usual trainning. The used variables were expressed by mean and standard deviation. To identify whether there were significant differences between genders, the t test was used for independent samples. In order to determine the degree of relevance we used P.
