Wnioski z artykulu w skrocie: bez rekawic uderzenia raczej wertykalne gdyz sa bezpieczniejsze dla rak, w rekawicach uderzenia horyzontalne gdyz majac dodatkowa ochrone ze strony rekawic mozna uderzac z wieksza sila przy tej technice.
Ciekawa jest rowniez czesc dotyczaca "mitow" o uderzeniu wertykalnym, ktora polecam przeczytac.
Ponizej duzy fragment z tego artykulu.
However, the risk is significantly reduced through the biomechanics of throwing a bare-fisted punch. Old style pugilism, which was built primarily on linear action, and emulated the thrust of a sword used a vertical fist, rather than today’s horizontal fist.
With a vertical fist, the entire arm is extended in one line from the shoulder through to the fist. The elbow is tucked beneath the arm as opposed to jutting outward, and the wrist is kept straight. This changes the angle at which the fist connects, and maximizes the striking surface by using the whole fist and not just the first two knuckles. Even when throwing a “rounding blow,” which is the ancestor of today’s hook, the vertical fist was used – either normally or inverted. Punching with a vertical fist provides fewer places in the arm for energy to “get lost” (like a bent elbow or wrist), and it provides more protection for the arm as a whole. The result is that that more kinetic energy is realized as force, and is distributed evenly across the fist. This protects the hand more than if the force was concentrated in one area, while still providing a powerful blow.
Professor Mike Donovan, an ex-middleweight champion, in his 1893 book The Science of Boxing, advocated using using a three-knuckle landing, vertical punch. Jack Dempsey was an advocate of the three-knuckle, vertical punch, as it worked well with his "power line" theory (similar to the Wing-chun centerline theory).
However, the benefits of punching with a vertical fist are neutralized when wearing gloves. The hand is already protected so linear blows may be replaced by more circular blows like the “corkscrew” jab and, of course, the hook. These blows may be thrown with more power because they have the increased energy of momentum behind them, as well as the weight of the gloves themselves, which may weigh anywhere from 8 to 20 ounces. Additionally, because boxers need not worry about breaking their fists, they may throw more powerful punches. Gloves, due to their size, act much like small shields around the hands, and canmaybe used to block incoming blows. Modern boxing guards reflect this, with the hands are held close to the body to easily tuck and cover. Gloves also make getting through a modern guard with linear punches more difficult, which works to the defender’s advantage when blocking shots to the stomach or sides with the elbows, forearms, and
biceps.
The older guards, or “attitudes,” were far more extended because the fighters could not rely on the extra protection gloves provide. They needed to block many blows farther away from their bodies. This is particularly true for shots to the head, which could not effectively be blocked with the modern tuck and cover. Combatants needed time to react and parry, having little protection close in. Therefore, the distance in bare-knuckle pugilism was considerably longer than in today’s boxing, being fought just outside the range where each antagonist could hit the other without moving his body or feet.
P.S. Wuxia, w jaki sposob uderza sie w modliszce?
