In any sport action there are three main
parameters speed, forth and precision. Now it is time to make an analysis of
the precision essence. How the brain controls the precision? How the brain
knows when some muscles should create their maximum contraction and when they
should stop and relax. How the brain controls time of muscle contraction for
precision action?It could be more
others questions about precision of sport actions. To know the answers it is
necessary to clarify that the brain has only the exiting stimuli (action
potentials) as the single instrument to make and control all processes and
actions. It is also very important to know that the sensor system of the human
body is mostly work as sources of the action potentials to characterize the
sport actions.
When an athlete makes a task to do sport
action, he gets the excitation in the cortex, the action potentials communicate
with proper parts of the brain for analysis integration and making program for
muscles, balance and equilibrium. The cells of muscles start contracting and it
goes up to the point when the brain will get the sensors signals which the
brain correlate (compare) with the results of the sensors signals have been
received from the previous successful sport actions taking from the memory of
the brain. As far as many muscles have been involved in any sport action the
brain has got the signals from each of them and needed to evaluate all and to
control their program of further contracting simultaneously comparing them with
memory results of sensor signals. Usually sport actions are very fast and brain
should work in extreme conditions. The faster sport actions the more failure of
them.
The improvement of precision of sport
actions lays in increasing the speed of interactions between the brain parts,
involving in actions. This could be done by thousands repetitions in the DIRECT
ACTION as a single process or continues workouts in the REFLEX ACTION as thousands
processes per second.
