Tip: After clicking the "Start" button, pay attention to the color change in the square. Once it changes from white to another color, click the "Stop" button to test your reaction time.
1. Reaction speed refers to the human body's ability to quickly respond to various signals ** (sound, light, touch, etc.).
2. People usually assess athletes' reaction capabilities by measuring reaction time, that is, the time athletes need to respond to signals **. Athletes' reaction speed to specific signals should be measured according to the characteristics of different events. For example, in sprinting and swimming, athletes mainly receive auditory signals to start the competition, while table tennis players mainly receive visual signals to make tactical responses.
Reaction speed mainly depends on the characteristics of the receptors (visual, auditory) and other analyzers, as well as the coordination between the central nervous system and neuromuscular relationships. The quality of reaction speed is greatly influenced by genetic effects. For example, the reaction time of people who have not engaged in specialized training is usually between .2 and .3 seconds, and even a well-trained athlete can only reach .1 to .2 seconds. Therefore, the improvement in reaction speed during the training process is very small.
