I'm interested in whether others have experience or know about badminton improving ability in other sports. Note that I am excluding fitness related improvement. The only guy in both my local table tennis and badminton clubs told me that badminton would improve my table tennis. Since he went from badminton to table tennis rather than the reverse I assumed he didn't know what he was talking about. I've barely played table tennis for over half a year, and while I'd normally expect to be quite rusty I'm definitely playing a lot better than I did when practicing regularly. There's no way this could be a coincidence. It's not just that my forehand and backhand are better, but all of my serves are better, which is curious since table tennis and badminton serves are nothing alike. I feel like I have more time when shots are coming to me now in table tennis. I read an article about the benefits of playing badminton which says: 'With great power comes great responsibility and with badminton, you will develop lightening quick reflexes. Badminton is the fastest sport and hence, you need to respond quick. You need to be physically swift to reach the shuttle and mentally agile to work out where to move to return it, and how to hit it to win. The combined agility of mind and body will advance your ability to process thoughts and accurately develop a plan of action, both on and off the court. The fact that one needs to respond quickly, requires high levels of concentration. It builds on its own and helps with concentration in other avenues as well.' I have ADHD and slow processing speed, so this all sounds right to me. I found a question answered by a former national table tennis coach who was asked about whether taking up badminton would hurt table tennis ability. He responded 'I don't think it will hamper your game. I think it will give you some aerobic fitness and also perhaps some more court awareness.' I also found an article in which Roger Federer credits sports he played when he was young including badminton for developing his hand-eye coordination.
