It’s better to have some ice patches put on your arm and legs as soon as you retired from the court. But only those professional players/athletes could have done that. So, my suggestion is that it’s better later than never. After doing that few times, then you should find the difference or improvement, I believe. That tactic works very well with me.

I watched this moive on TV few months ago, the football star sat in a cold water tub with lots of ice cubes in it right after training course.

One thing I forgot to mention, --- congratulations on the resurrection you’re enjoying!

I have not played badminton sport for long. The muscle in my legs does not have the kind of thrust the sport demands for.

You talked about sports injury in some other logs. Actually, I’m a sports injury expert. I might have all kinds that one can possibly image, from toe to the neck. Since you seemed suffer from it as well, I would suggest you prepare some ICE, after you come back from the court, putting some ice on your arm and legs. It’s recommendable you could take cold shower, I think in such hot summer, it should not be a problem. Anyway, the point is to keep your arm and legs cool aft exercising. See what 王建民 did to his throwing arm after retired from the pitcher’s mound. He put ice to his million-dallored arm. ICE could prevent you from muscle pain, and prolong your playing life.
