These techniques are supposedly the quickest hand techniques for boxing and martial arts respectively.
The jab which is executed from a front stance when two individuals are standing in front of one another face to face. When executed the lead hand is snapped out straight in front toward one’s opponent in the face area to block or cover the face of one’s opponent, the shoulder is exposed high enough to allow the one executing the technique to hide his/her chin behind his shoulder with the chin somewhat tucked down into the chest.
The Back first is executed from a side stance. The person executing the technique’s feet will be pointing straight ahead of him/her with his or her head looking to the right or left. Whichever side they are looking is the hand in which they will be using to execute the back fist, the back fists target is usually to the back of the head with full extension but I’ve see numerous back fists to the forehead jaw etc…it is an angular technique meaning, using the side stance which is that stance I mentioned earlier where the feet are facing forward but the head could be facing either to the right or left but whichever side the head is facing is the side the person executing the technique will have his/her hand up and primarily be used as the execution hand, which if executed properly should extend to the back of the opponents head striking him/her with the two most pronounced knuckles of the hand which are hopefully the two fingers next to the thumb on the thumb side of the lead hand. I hope that doesn’t sound confusing but that’s the back fist. It sounds a lot more complicated than it is and even less effective in a situation when you need to hurt someone.
However, of the two techniques the jab may be the more effective technique but this may also depend on the circumstances. The jab is used to keep your opponent occupied or off you one might say, while the back fist is used as scoring technique and to close the gap and possibly followed up by other techniques. The jab can be stiff or snapped out to keep in your opponents face. It can be fast and hard, fast and weak, or hard and stiff either case usually a very good technique in boxing when you need to keep your opponent at bay.
In an MMA event you are more likely to see the jab then the back fist. Back in the days of full contact karate, PKA Super-lightweight champion Richard Jackson was known for his spinning back fist. He was so effective with this technique he could spin into you and knock you out utilizing it. I doubt you’ll ever see this technique again. As of this date I haven’t seen it in an MMA event and most tournaments most likely would penalize you if you actually make contact using the technique. An effective technique that may never be executed or seen on prime time again, most likely not in an MMA event and most definitely not in the NMAL, however I know you’ll see many of back fist. I true martial art technique.
Always something to talk about,
