Correct throwing skills of darts
The throwing skill of darts is a big problem in darts game. In order to achieve better results, we must first understand the mechanism of darting. When you are still playing darts, darts will be thrown in the form of parabola, which follows the parabola of sticks or bullets. The radian of parabola is determined by the throwing force. The greater the throwing force, the shallower the curve of the arc.
To use these darts throwing skills, we must first understand how hard our arms are when throwing darts. The best way to understand it is to think of your arm as a machine. This machine consists of three parts (hand, forearm and upper arm) connected by joints (wrist and elbow). The last part of this machine is a fixed part (back) connected by another joint. The picture on the right is a picture of this machine.
