Punches in boxing are the main means of attack, the most important component of the technical equipment of the boxer. The skill level of the athlete is determined by an extensive set of options for attacks, performance or reliability of their implementation.
The accuracy of the process is a consequence of the impact of control actions and depends on the following parameters:
- Speed of the shock movement.
- The duration of the movement. It is shorter than the more difficult to manage.
The impact force can be determined using Newton’s second law:
F = mV / t, where
M – mass (mass strike), the size of the mass is about 3.2% of body weight boxer and contains a lot of brushes (1% of body weight), forearm (2% of body weight) and shoulder (0.2% of body weight) .
Average speed of the hand when hitting the master of sports of 4-5 m / s, the time of the collision brush has a maximum speed (the master of sports, it reaches 8-10 m / s).
Per 1 kg novice boxers distributed 2.25 kg impact force, and the masters of sports 4kg, the members of the team – 8.2 kg.
When you hit the brush takes a significant load, so you need to properly compress fist.
The main factor wrist injury and ligament – knuckle wrong position at impact.
