A question to you experts, I was wondering about something a lot: When I see competitive skaters train, they do like 80% of their practice time jumps (double, tripple), they do a lot in one practice session, every day. Why don't they get problems with their knees (meniscus)? A few do, but most not. Now me as an adult skater, I skate since 4 years, 4-6 hours a week. But since 2 years, I have knee pain when doing to much (single) jumps, I don't jump high, maybe just some inches http://www.youtube.com/watch?v=8ZEShRuUEWQ To much means, more than 10 in one session (two hours). Now I even must reduce them to max. 4 a session...because I'm afraid that I might get a permanent knee injury when doing to much. I love skating to much that I can't be off longer than 3 days if I don't jump, my knee seems ok... btw, I'm not heavy, just 59kg, with 1.71cm hight... Am I right that the muscles in the legs need to support the knee to prevent a heavy load/pressure on them? I belive I don't have enogh muscles that I'm in pain very soon. Its so frustrating, can't practice jumps much, I didn't even try loop and flip yet because of that I'm so jealous of everyone who can jump all the time without any consequences... Any ideas?
