There are many different varieties of strikes. An attack with the hand closed into a fist is called a punch; an attack with the leg or foot is referred to as a kick; and an attack with the head is called a headbutt. There are also other variations employed in martial arts and combat sports.Contents1 Usage 2 Punches 2.1 Palm 2.2 Knife hand 2.3 Ridge hand 2.4 Spear hand 2.5 Hammerfist 2.6 Extended knuckle 3 Kicks 3.1 Knee 4 Other strikes 5 Striking Principles 6 The dangers of fist strikes 7 See also 8 References // UsageStrikes are the key focus of several sports and arts, including boxing, karate, muay thai, taekwondo and wing chun, some martial arts also use the fingertips, wrists, forearms, shoulders, back and hips to strike an opponent as well as the more conventional fists, palms, elbows, knees and feet that are common in combat sports. Other sports and arts, such as judo or wrestling employ no strikes in focusing on grappling techniques.PunchesMain article: Punch (strike)The most common is using the front of a closed fist, other uses of the hand for striking are given below.PalmA strike using the palm of the hand. Whether the hand is open or the fingertips are folded against the bottom knuckles, palm strikes hit with the bottom part of the palm, where the hand meets the wrist. The hand is held perpendicular to the wrist to avoid hitting the softer inner wrist tissue against the target.The bottom ridge of the palm is a surprisingly solid striking surface, and can do just as much damage as a closed fist when utilized properly (some studies have shown that a palm strike actually can produce more energy then a a punch in most cases), with far less risk of injury to the striker's own hand.The palm strike is useful as it is thrown in a more relaxed manner than a clenched fist. This is because clenching the fist shortens the extensor muscles of the wrist which counter the action of flexor muscles of the wrist used in punching. Many martial arts teach to keep the fist clench relaxed until impact in order to maximize the speed of the punch.Targets are numerous and some examples include the nose, jaw ,ears, back of the head, the groin, the kidneys and abdominal cavity. Some combat sports, such as Pancrase, have forbidden strikes using the clenched fist but permitted strikes using the palm.Knife handMain article: Knifehand strikeA strike using the part of the hand opposite the thumb (from the little finger to the wrist), familiar to many people as a karate chop, Shuto or Tegatana. This refers to strikes performed with the side of the knuckle of the small finger. Suitable targets for the knife hand strike include the mastoid muscles of the neck, the jugular, the throat, the collar bones, the 3rd vertebra (key stone of the spinal column), the upper arm, the wrist (knife hand block), the elbow (outside knife hand block), and the knee cap (leg throw). In many Japanese and Chinese martial arts systems, the knife hand is used to block as well as to strike.Ridge handBy tucking the thumb into the palm, a striking surface called the ridge-hand, or reverse knife-hand is formed, extending a few inches along the inside of the hand below the first knuckle of the first finger. Ridge-hand strikes commonly are delivered with a hooking motion, or with a straight arm swingSuitable targets include the mastoid muscles of the neck, the jugular, throat, nose, jaw, and the groin.Spear handDelivered just as with a punch except that the hand is held open like with a knife hand. The intended striking area are the tips of the fingers.The ideal targets are the eyes and throat. This technique is generally unsuitable against most other targets due to the high probability that one might break their fingers.HammerfistA strike with the bottom of a clenched fist, using an action like swinging a hammer, but can also be used horizontally like a backfist strike using the bottom fist.This strike will not damage the bones of the hands as there is no compression of the knuckles or metacarpals, and there is no leverage to bend the wrist.The hammer fist strikes cricket ball sized areas on the body, hence is particularly effective for striking the Occiput, the temples, the nose, the mandible, the wrist (for blocking punches), the sternum, and the ear (although a cupped hand is more effective). The hammerfist is sometimes used during "ground-and-pound" striking in mixed martial arts to avoid damaging the bones of the hand....(and so on)
