Hardness: The ball stays on the racket for only four to six thousandths of a shot. During the swing before the shot and when the racket hits the ball, the stick has a process of bending and restoring, and the ball has already left the face before the racket has returned to its original position. In the case of the same strength of the player, the softer the stick is, the easier it is to bend during the swing before hitting the ball, and the greater the bending, which drives the head to move at a greater angular velocity, resulting in greater hitting power. The harder the stick is, the less power it can transmit to the ball when hitting the ball, but it can reduce the transmission of the ball shock. For the frame, the harder the frame is, the less likely it is to deform and twist when it comes into contact with the ball. The more power can be transmitted to the badminton, the less vibration is transmitted.
Torque: The so-called torque refers to the magnitude of the torsion of the racket surface when the racket hits the ball. The smaller the torque, the better the control of the ball.
Relationship between hardness and ball control:
1. Directional control: When the racket hits the ball, the ball can be hit back according to the direction or angle of the shot. The harder the beater and the frame are, the more stable the control is to the direction and the harder the racket torque is when the ball is not in the sweet spot of the face.
2. Depth control: This refers to the control of the distance (drop point) of the ball being hit back. The depth control is related to the strength of the player itself. Under the same condition, the softer the shot, the better the control of the depth.
