Boxing is a fist fighting sport between two matched combatants (对手) wearing padded gloves. A boxer’s primary aim is to land as many blows as possible to the head and torso (躯干) of the opponent, using strength and speed to dominate the contest. One of the oldest sports still practiced, boxing dates back to thousands of years ago. Today the sport is popular in many parts of the world and encompasses (包括) both amateur and professional matches.

For most of the 20th century boxing attracted huge fan and media attention in the United States. Some boxing champions became legendary, larger-than-life figures, such as Jack Dempsey, Joe Louis, and Muhammad Ali. Criticized to varying degrees throughout its history for its violent nature and high injury rate, boxing has somehow always managed to survive——and even thrive——as a sport.

Modern boxing regulations are based upon the 12 rules set out by British boxing officials in the mid-19th century. These rules became known as the Marquess of Queensberry Rules, named after the 8th Marquess of Queensberry, John Sholto Douglas, who sponsored and published them. In addition to in-the-ring rules, modern boxing also has specific regulations regarding eligibility for the fighters themselves.

The modern rules for professional and amateur boxing differ, but both types of contests are divided into time periods called rounds. In professional boxing, each round lasts three minutes; in amateur boxing, two minutes. A one-minute rest period between rounds is standard. Amateur contests consist of three rounds; professional contests may consist of up to 12 rounds. A bell is usually sounded by a timekeeper to begin and end each round.

A key step in making boxing safer and more respectable was the introduction of gloves, ending brutal bare-knuckle competition. Boxing gloves are heavily padded to soften the impact of the blow and to protect the hands of the boxer. As an added protection, the hands are taped before being placed in the gloves, which are essentially huge mittens. Professional gloves usually weigh between 170 and 226g; amateur gloves average 226 to 340g.

     A new study has revealed that non-smokers who repeatedly breathe in others' tobacco smoke are more

likely to have some degree of hearing loss. Researchers studied a total of 3307 adults aged between 20 and

69. The degree of hearing loss in each ear was assessed by testing the ability to hear pure tones over a range

of frequencies from 500 Hz (low) to 8000 Hz (high).

     Men, those who were older, and those with diabetes (糖尿病) were significantly more likely to have high

frequency hearing loss. And this was true of those who were former smokers and those who had never

smoked. But even after taking account of these factors, both former and passive smoking were associated

with damaged hearing.

     Former smokers were significantly more likely to have damaged hearing. The prevalence (流行程度) of

low to mid frequency hearing loss among this group was 14 percent. And almost half (over 46 percent) had

high frequency hearing loss. Although the risk was not as strong among those who had never smoked,

almost one in 10 (8.6 percent) had low to mid frequency hearing loss and one in four (26.6 percent) had high

frequency hearing loss.

     And the stronger findings among former smokers suggested that continued passive smoking in this group,

even at low levels, could continue the progression of high frequency hearing loss that began when they were

active smokers, say the authors.

     "Further research is required to determine whether passive smoking increases the effect of noise exposure

and aging on hearing," they conclude."If this finding is independently confirmed, then hearing loss can b

e added to the growing list of health consequences associated with exposure to second-hand tobacco smoke."

The study was published online in Tobacco Control.
