Online reaction speed test

Reaction speed:

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

2. People usually assess athletes' reaction ability by measuring reaction time, i.e., the time athletes take to respond to signal stimuli. The response speed to specific signals should be measured based on the characteristics of different events. For events like sprinting and swimming, athletes primarily react to auditory signals, while table tennis players mainly rely on visual signals for technical and tactical responses.

Factors affecting reaction speed:

Reaction speed mainly depends on the characteristics of human receptors (visual, auditory) and other analyzers, as well as the coordination between the central nervous system and the neuromuscular system. The quality of reaction speed is significantly influenced by genetic effects. For instance, untrained individuals typically have reaction times of 0.2 to 0.3 seconds, while well-trained athletes can achieve 0.1 to 0.2 seconds. Thus, the improvement in reaction speed during training is
