Can you answer my problem?

yesterday i went to a sports thing where we play games like grand champion, dodge ball, etc. but today im sore for it and i have basketball practice. I asked her if we could skip practice today, and she said no because it is healthy to work your muscles when you are sore, but i went online and it says that you need to rest if you are sore. i tried to tell my mom not to go, but she says not to argue with her. I know that if it hurts just to walk around then it will hurt a lot when my coach tells us to sprint ( we have to every practice) and i really dont want to go but my mum told me that i couldnt argue with her about, should i just go anyways, or should i continue to talk about it?
