The javelin throw basically requires an efficient release angle. The angle is at 30 ° to 36 °. Observations made on the ground in novice athletes are used as a single sample because athletes have difficulty directing the javelin to get the correct throw angle. Javelins that are produced with poor ability to release techniques result in the athletes inhibition to get maximum throw performance. This is caused by a stiff wrist. Stiffness in the wrist is one factor that causes inadequate throwing performance. The reason is that a javelin that is not at an angle of 30 ° to 36 ° will find it difficult to reach the maximum distance. Thus, the problem of the ability of the javelin release technique is of particular concern for research. In this situation, the researchers presented a device called the wrist to practice the simulation of the javelin release technique. So, with training using a wrist device, problems with stiffness when removing the javelin can be overcome appropriately.
