I want to know few shots about badminton:
There are so many badminton club and league players I've seen that seem to move and hit with excessive tension in their bodies. This tension is caused by pressure getting to the shuttle on time, frustration from wanting to hit the shuttle better or score more points and most likely a host of minor reasons that are causing a major issue.
When the body is tense, it is unable to perform anywhere near its optimum capability. A tense body cannot move as fast, hit as fast or as powerfully as one that is free from tension. Think about it. If you were to go onto court to play against a player you know you can easily beat, why is it your shots are so much better and you appear to move so much faster? Yes, you're not under pressure and therefore playing with a sense of freedom - freedom from tension.
One of the major adjustments I ask of most players is the way in which they grip their racket. I'm not talking about correct forehand or backhand grips here, although that does feature high on my list.
In this article I'm talking about the strength of your grip. If you grip your racket too tight, then your muscles are constantly under tension. This does not allow them to flow and carry out you instructions to move in a certain way in order to hit the shuttle. They are almost fighting to move in the right sequence.
A tight grip then restricts the amount of power available to these muscles, which only leads to a poor result and disappointment for the player. If you consistently grip the shuttle too tight, then you're running the risk of injuring your elbow. Tennis or golfers elbow is extremely painful and is frequently caused by your grip being too tight, or your racket grip being too small for the size of your hand.
