As an amateur goalkeeper, how to protect your joints?

First of all, it's best to try hard or embarrassing saves as little as possible ~ I started playing goalie in the third grade, graduated from college, and suffered many injuries, but after I got to college, even if I jumped on the concrete floor, I was rarely injured, really. Try to make the back of your shoulder touch the ground as much as possible. Your lateral jump may be on the right side of your body, so it will only hit your hip bone. Try to lean back and touch the bottom with your shoulders slightly close to your back, even if it's ugly. Of course, it will be more effective if you can roll beautifully on the ground like a professional goalkeeper. I once studied at Luneng Football School with my friends, but no, hehe ~), I think this place will be buffered. Of course, I can't help it if you say I'm not a professional, because I'm not a professional athlete, hehe ~ ~
