Wine glass effect of sports skills

The wine glass effect of sports skills is a metaphor for the types of compensatory reflex regulation.

Excitatory response: the response to the interference action, the latency is 80- 120ms, which is more flexible and faster than M3. Excitative reaction is much slower than M 1 and M2 reaction, but it can't be called random reaction. It is as sensitive to the change of stimulus as the traditional reaction time, but it is faster than the action reaction time, and it is done under the subconscious situation, such as the "wine glass effect". That is, when the glass in our hands slips slightly at a banquet, we will immediately increase the strength of the forearm muscles to hold the glass after feeling it through our fingers, and at the same time reduce the strength of the forearm macro biceps to lift the glass to prevent the glass from slipping.
