| What is the speed of reaction limited by? The answer is by thespeed of muscle and nervous system functioning
A man needs 0.1-0.3 seconds for giving a visual reaction
When a man reacts to a very strong irritation, dangerous for life (for instance he pools out his hand from a hot stove) .a simple reflex is is shown. The receptor transfers teh signal by nerve fibril, he then goes up to the brain and then the brain transfers the signal back to them. The speed of nerve impulse makes up several meters/second.
If the matter comes to the human's reaction against a falling brick, what happens here is that the eye transfers the signal of fast movement not only to sections of the brain, where they are processed (and we understand the brick is falling), but also through special nerve tracts (to muscles), which provides a quick reaction and an action for avoiding the falling brick.
If we talk about the reaction during a tennis game, than a gradual improvement of the reaction is related to the formation of stereotypical reflexes, that allows the reaction to appear without the interference of the main part of the brain (unconsciously), and, really important, such reactions are shown without feedback.
So, it can firmly be said that the reaction is trainable and you can increase it by playing sport games. Tennis is a very good one. |
