The article describes external ballistic indicators of the flight of the
nucleus. The results of the study of the dependence of the external ballistic indicators of the flight of the core with the result of shot
put, athletes who are at the stage of specialized basic training are presented.
The research was attended by 12 shot putters 15-17 years who were at the stage of specialized basic training. In article
used the following methods: analysis and generalization of scientific-methodical literature, analysis of video materials, methods of
mathematical statistics.
As a result of conducted research, were found the following external ballistic indicators of the kernel flight in the shotputters
at the stage of specialized basic preparation: the kinetic energy of the kernel 313,34 10,24 J, the greatest a flight altitude of the shot5,02 0,46 m, the smallest overload of the shot 0,004 0,0004 g the largest overload of shot 0,010 0,0003 g, the
largest pressure which affects the shot during its flight 90,43 2,81 Pa, the smallest pressure which affects the shot during its flight
39,35 4,11Pa, the largest speed of a flight of the shot 12,49 0,19 m/s, the smallest speed of a flight of the shot 7,94 0,41 m/s,
losses of result as a result of the shot deviation from the set trajectory 7,67 1,83 sm.
Analysis of the relationship external ballistic indicators of the flight of the shot with result of the shot put showing that during
the preparation of the shot putters is necessary in addition to reducing losses results as a result of the deviation of the shot from the
set trajectory due to the actions of the forces and moments during his flight in the first place, first of all, seek to influence these
indicators external ballistics: kinetic energy of a departure of the shot, largest speed of a flight of the shot and largest pressure which
affects the shot during its flight.
