and some deaths were caused by a fighter hitting their head on a stone or rail. Weighted training gloves Weighted training gloves are sometimes used in order to add resistance to punching exercises. Such gloves standardly range between one and three kg. As their usage over time typically increases the boxer's strength in that range of movement, they are used to increase the speed and power of a punch; in order to achieve this, their usage may be alternated with normal unweighted punching practice. Care is taken that the muscular adaption for the weight does not impair the normal punching action. Light dumbbells are sometimes used on a similar basis to weighted gloves. Illegal modification of boxing gloves On 16 June 1983 at Madison Square Garden, New York City, Luis Resto unexpectedly beat the previously undefeated Billy Collins Jr. An investigation found Resto's gloves had been illegally modified, with padding removed by his trainer, Panama Lewis. As sport journalist Oliver Irish summarized, "Lewis served two years of a six-year prison sentence for assault, conspiracy, tampering with a sports contest and criminal possession of a deadly weapon (Resto's fists)". Influence of boxing gloves in other fight sports Open-fingered and open palm MMA gloves or grappling gloves, which are frequently used in mixed martial arts bouts, are not boxing gloves. Similar to the wrist-supporting, closed-thumb, broken-knuckle kempo gloves popularized by Bruce Lee's 1973 movie Enter the Dragon, they provide some padding to the person wearing the glove, but leave the fingers and the palm area open and available for intricate wrestling and grappling maneuvers such as clinch fighting, which are illegal in the sport of modern boxing.
