tennis is becoming an increasingly popular sport in Brazil in the past few years, and consequently, it has become necessary to study the variables that influence the motor development of this activity. This present study had the main objective of planning, developing and applying work loads for the physical preparation of five tinnis players, four boys and one girl, from 12 to 16 years of age, and to observe the development of the motor capacites specific for tennis: speed, agility, resistance, lactic anaerobia and muscular power of the inferior ans superior limbs. The method used to structure the training was the pendulum method proposed by Manso et al (1996, apud Gomes 2002), which consists of varying the motor capacities in each training session and alternate the priorities and, at the end of each micro-cycles, returning to the motor capacities previously worked. The training plan consisted of theree weekly sessions of ninely minutes for six months. The statistical analysis used was Student´s t test. The main results obtained showed that the motor capacities: agility, anaerobic capacity and muscular power of the superior limbs, presented a significant p<0,05, whereas the other bi-motor capacities that has a direct relation with the development of this sport, despite the fact that some of them did not present statistical significance.
