Tennis. Analytics when applying the most powerful shot

Actuality. Many coaches mistakenly assume that the flight of the ball on a straight line trajectory with a flat feed and impact will hit the tennis net. As a result, it is considered that adolescents do not need to teach a flat serve, but to teach immediately spin serve with the rotation of the ball. Purpose of the article: to show analytical and theoretical researches of flat shots in tennis their ability for the best application. Methodology. Integration of knowledge of various sciences and their methods to solve the problems of physical education and sports training. Scientific novelty. An analytical method over of calculation of descriptions of motion is brought by means of kinematics. Factors affecting the trajectory of the ball's flight have been educed. The analytical dependence of the instantaneous and final speed, range and altitude of the ball on the mechanical parameters without taking into account the air resistance is derived. The analytical analysis of these shots is expounded with initial velocity, depending on the angle of slope to horizon under that there is a blow to the ball in the distance h from the plane of court. Correcting coefficients over are brought. A percent on that actual speed can change in a flat blow and serve is given. The advantages and disadvantages of these strikes are given. The terms of implementation of flat serve, her advantages and defects, are examined. Conclusions. Most powerful and at the same time most difficult for implementation flat shots at that a ball is not given by a rotation are considered. It is necessary to take into account that rectilineal and curvilinear trajectories outbowed only in a vertical plane are named flat. A trajectory of flight of the ball sent by a player can be different. The decisive influence on it is the rotation of the ball during its flight. The rotation of the ball during its flight has a decisive influence on it. Factors affecting the trajectory of the ball's flight have been clarified.
