[ti:Study Raises New Concerns of Dementia from Playing Professional Football] [by:www.otzgay.live] [00:00.00]更多聽力請訪問51VOA.COM [00:00.00]A study of former professional football players in Scotland [00:04.71]finds that they were more likely to die from dementia than any other cause. [00:11.55]The results bring attention to the risks of head injuries from playing the sport Americans call soccer. [00:21.04]Researchers from the University of Glasgow reported the results in the New England Journal of Medicine. [00:30.20]They compared the causes of death of 7,676 Scottish men who played professional soccer [00:38.88]with 23,028 similar men from the general population. [00:45.96]The men were all born between 1900 and 1976. [00:53.28]Over 18 years of study, 1,180 players and 3,807 of the other group died. [01:04.52]The players had a lower risk of death from any cause until age 70. [01:12.12]However, they had a 3.4 times higher rate of death from diseases affecting the brain, [01:19.18]such as Alzheimer's or Parkinson's. [01:23.88]Former players also were more likely to receive dementia medicines than people in the other group were. [01:32.88]Doctor Robert Stern is a scientist with Boston University. [01:39.04]He studies sports-related brain injuries. [01:43.96]He noted that the findings were about professional players. [01:48.46]He said they might not apply to those who play for fun, college players or women. [01:57.12]Stern said parents "should focus on the...health benefits [02:01.55]from exercise and participation in a sport that their children enjoy." [02:08.16]He added that parents should still consider the risks of heading – hitting the ball with one's head. [02:17.08]Stern's comments were published with the study in the New England Journal of Medicine. [02:24.52]Greg Clark is chairman of the English Football Association. [02:30.36]The organization helped support the study. [02:33.64]Clark said, "The whole game must recognize that this is only the start of our understanding [02:41.79]and there are many questions that still need to be answered." [02:47.40]The English Football Association's medical advisory group [02:51.62]has not said it is necessary to change how the game is played. [02:57.96]Officials across all levels of soccer can stop games for three minutes to fully examine head injuries. [03:07.36]However, some experts believe that is not long enough. [03:13.28]The English Football Association also is pushing soccer's worldwide lawmaking body [03:19.97]to permit substitutions for players who suffer concussions during gameplay. [03:27.44]The family of former England soccer player Jeff Astle is leading efforts [03:33.24]to learn more about the long-term effects of head injuries in football. [03:40.24]Astle died at age 59 in 2002. [03:46.48]His death is believed to be related to repeatedly hitting heavy, leather balls with his head. [03:54.96]In 2017, a British study of the brains of a small number of retired players [04:01.68]who developed dementia brought attention to the damage [04:05.91]possibly caused by repeated strikes on the head.
