hi as the title says could you sight some waYS to quickly change grip quickly but still with power this is a bgi problem for me when i am returning smashes
practice it infront of the TV, it will become send nature after about an hour. Just swapping, you hands learn the transitions better.
lol he means infront the tv beacause its something that you can do while your at home in your free time when your not doing anythigen once you to get the feel for it easily and all. and then once you get use to doing it at home you can take it to the courts and give it a try there.
WALL TRAINING. Hit the shuttle to a wall and play both forehand and backhand. Eventually you will be very fast enough in changing grips during a match.
according to the grips guide in the Badminton Bible there isn't really a so-called backhand and forehand grip. it goes into quite a bit of detail, so i recommend giving it a good read. in short, to switch quickly, use the basic grip as your "base position". you also mentioned about power and returning smashes. when you use the basic grip, you should have sufficient power to return on both the backhand and forehand. imo, its more your wrist power than anything.
Gripping the racquet too tightly will hamper your ability to change grips quickly and reliably. I always try to hold the racquet between thumb and forefinger mainly, until I;m committed to a shot. ie, nice loose grip til I've decided between forehand and backhand grip (or if you prefer, between neutral, forehand, bevel or thumb grip)
As the bear said you should have a moderately loose/soft grip in between shots. This way you can make the quick switch.
For singles, u shd have time to switch it. For doubles, typically people hold it near the cone and expect low or defensive play. When the shuttle goes up, you shd be able to switch your handle to attacking mode. Hope this tip helps. Back to attitude and discipline. See how the pro do it.
