What is the meaning of counting seconds often mentioned in Sanda, boxing and MMA competitions?

In principle, mma is a boxing intensive reading without counting seconds. It means that when an opponent knocks to the ground and doesn't get up for a period of time, he will be sentenced to lose Sanda. The referee's intensive reading on the court is to feed the protection players to rest during this time and then ask them if they can still play. Personally, MMA coach from Taiwan Province is currently teaching in Shenzhen. I hope my answer is helpful to you. If you are not clear or need to consult again, please ask me. Thank you.
