If you're anything like me, you've always had a vague idea of the benefits of warming up, but never got around to actually start doing warm-ups. You might also think that warm-up consists of mostly of jogging and static stretches. Well nowadays, apparently, it's a lot more. What opened my eyes was a couple of articles linked by Badminton Finland. They referred to a study that reported a 66% decrease in injuries in the floorball teams that had a specific warm-up routine. (The study is written in English.) Floorball is probably even more dangerous to ankles and knees than badminton, but our beloved sport does not fall far behind in this regard. The specific warm-up routine they used is described by a lot of strange words like "neuromuscular" and "dynamic", but in practice you don't need to know a whole lot about the theory. The important message is that there are effective ways to prevent injuries, to improve the competitive performance and to increase one's mobility in the long run. For me, preventing injuries is perhaps the most important part of the benefits because of my age (soon to be 37). I guess there are injury-prone periods also in teens or so, but I understand that age becomes a risk factor close to middle age and beyond. This is why a good warm-up program might be even more important for older players. Badminton Finland has a nice demonstration of an active, dynamic warm-up program on Youtube. (The titles are in Finnish, but mostly you don't those.)

I recommend trying them out. At Badminton Life, Richard Gibney talks about the same themes.
