When you say reflexes, i think you mean the speed you move in the court and the amount of time for you to react before returning the shuttle. To increase the speed of movement in the court, practice foot work and shadow drills. To be faster to react to a shot, practice, use certain return shot for certain shots you recieve( like lifts for smashes and deep clears for smashes ) Hope this helps
Net level drives is one popular practice amongst rookies, amateurs and pros. Stand at the midpoint of the court length, your opponent doing the same on the other court, but same side. Drive the shuttle as close as possible to the net but with power towards the other side. What it helps : reflex - you are too close to have time to think of anything else, so depends on how fast your reflex is. accuracy - how close to the net you can drive
A question If you serve the bird, the bird falls on the line but not exactly on the "out" zone! How do you discern if it's an "out" or not?
Like L-vin said, it's not about reflex but reaction time. We all have lightning fast reflex. When someone smashes at your face, your brain tells you right away that you have to either duck, or block it with your racket. That is "reflex". The reaction time is the time it takes you to actually do what your "reflex" tells you to do. You can practice by yourself on your swing, as long as you know what the proper swing is, but for foot work, have someone stand at the net and randomly points you to any of the 8 points. You have to move to the spot and back to the center as quickly as you can, back remember to keep your balance at all times. It's no good just to do this yourself, because you kind of know where you want to go next, and surprise is what keeps us on our toes.
If you want to try improving your reflexes you could try going on court, and get somebody on the other side. Face away from the net and get your mate to hit the shuttle flat and fast in your general direction. When you hear him hit it, spin around and try and return it.
Our National Team(PHI) does this: Sprint and Quick Turn: An exercise where the player's back is facing the net. The coach then signals the player to turn around and try to hit as many shuttlecocks as possible. This is to improve quick anticipation and reflexes. (excerpt from an article)
oh ok thanks but you can also say i want to improve on my reaction time and accuracy too.somtimes i find that its because the angle of contact of my racket to the shuttle was not good thats why the shuttle flys out or simply just miss the shuttle.
Play against the wall, since this increase your wrist power as well as reactions. If you are with someone else then both stand on the service lines or slightly infront, get down low so your rackets are upright at the level of the net, and play slow drives to each other. It is harder than you think as you have to make a quick clean contact with the net, keep it under control, and react to your opponents reply too. If it is too easy then you shots arent flat enough or simply hit harder.
