Introduction

Modern improvement of physical education in the university has long been the subject of many sports specialists studying. Much attention is paid to the sports interests of students, who will have to solve various social and economic problems (Zheleznyak ,2007; Vilensky 2013).

Sectional work in various sports attracts young people to physical activity and thus to improve their health and physical education. There is a process of initial preparation and teaching students the basics of tennis in the tennis section of our university. The main shots in tennis include giving serve, groundstroke (right and left), return serve, volley, half-volley, overhead, drop-shot and drop volley.

Successfully play an active game from the back line of the court and prepare net approach, only a tennis player who has a wide arsenal of shots on groundstroke can effectively defend. In the modern game, they use both flat shots, spin and slice (cut) shots groundies. The external picture of the movements to the groundstroke ball is quite similar. However, they are performed in various conditions to solve various tactical tasks, which causes them to differ from each other. One of the elements of learning to shot is learning to flat shot. In various sources, a flat shot is described in different ways. In various sources, a flat shot is described in different ways. L. Zaitseva believes that with flat shots, the angle rotation of the racket to the plane of the court to the outside, respectively, is 90-70 ° and 60-30 °. In other sources (Maksimov, 1998; Metzler, 2002) it is argued that with a flat shot, the plane of the racket is located vertically to the plane of th e court surface.

This is not always true. Belits-Geiman (1977, рр. 62-65) notes that the flat trajectory of the ball's flight will be with flat shots and shots with the rotation of the ball, in which the translational velocity vector will be perpendicular to the axis of the ball rotation. He also notes that when hitting the ball bounced off, the plane of the racket is positioned vertically to the plane of the court surface (Brown, 2009, p.87). Shots, after which the balls are sent to the side of the enemy without rotation, are called flat. They have the highest flight speed and are effectively used as attacking shots in response to the opponent's short and high balls (Golenko, Zaitseva, Tarpischev, 2001).

Material & methods

The following methods were used: theoretical analysis and generalization of literary sources of scientific and methodical literature; sociological methods (evaluation of the performance of a flat filing among juniors and leading players; analytical method for calculating motion parameters using kinematics; pedagogical observation (more than 100 classes of the university's tennis section).

Results

Integrating the knowledge of various sciences and their methods for solving problems of physical education and sports training makes it possible to move from subjective judgments about different aspects of the training and training process to accurate objective assessments and corresponding conclusions.

The end of a racket swing determines how the shot will be: slice, spin or flat. It should be noted that the rectilinear and curvilinear trajectories, bent only in the vertical plane, are called flat. The trajectory of the ball sent by the player may be different. The decisive influence on it is the rotation of the ball during its flight.

It was found that a number of factors affect the ball's trajectory during a flat shot, such as:

* racket string surface;

* initial ball departure speed given to the ball by the racket;

* the angle of the ball and the angle of the racket to the surface of the court;

* height, relative to the floor at which the blow is being performed;

* air resistance which slows down the speed of the ball;

* the force of gravity, which turns the trajectory of rectilinear motion to the trajectory of motion close to parabalic;

* the value of the initial velocity;

* with the reflection of the ball from the rebound, the nature of the coverage of the court, etc. …
