Human body reaction speed testing tool

reaction rate

Reaction speed refers to the ability of human body to respond quickly to various signal stimuli (sound, light, touch, etc.).

People usually evaluate athletes' reaction ability by measuring the reaction time, that is, the time required for athletes to respond to signal stimuli. The response speed of athletes to specific signals should be measured according to the characteristics of different events. For racing events such as sprinting and swimming, athletes mainly receive auditory signals and start to compete, while table tennis players mainly receive visual signals and make technical and tactical responses.

Influencing factors of reaction speed

The reaction speed mainly depends on the characteristics of human receptors (vision, hearing) and other analyzers, as well as the coordination between the central nervous system and neuromuscular. The quality of reaction speed is greatly influenced by genetic effects. For example, the reaction time of people who are not engaged in special training is usually between 0.2 and 0.3 seconds, while that of a well-trained athlete can only reach 0.1 to 0.2 seconds. Therefore, in the process of training, the improvement of reaction speed is very small.
