20米折返跑

小编摘要:“20米折返跑”的英文表达是20-meter shuttle run。是长跑还是折返跑,这不重要,重要的是提高学生普遍的锻炼意识,加强身体素质,但不应当弄成“应试体育”。

“用20米折返跑代替800米、1000米跑,亲你支持吗?”近日,针对青少年心肺功能测试项目的探讨,在微博上一石激起千层浪。不少网友大发感慨:“支持啊!当年每次跑800米就有种想死的心,每次都有同学跑到泪流满面。”也有网友反对取消长跑项目,认为现在孩子的身体素质已经在下降,适当的强制性锻炼也有必要。更为理性的说法是:不在意项目的更换,只要达到强身健体的目的。

我们来看一段相关的英文报道

The 20-meter shuttle run pilot project is under way in the city's 18 schools, with about 5,000 students participating. The shuttle run involves running back and forth between two points 20 meters apart at increasing speeds."The long run failed to scientifically and objectively reflect a student's cardiopulmonary function and aerobic endurance," said Ji Liu, a professor from the school of sports and health at East China Normal University, who is also the leader of the pilot project. "The speed has less connection to their physical status," while cardiopulmonary function and aerobic endurance is an important indicator of a person's fitness, he said."The long-distance run is a combination of aerobic and anaerobic exercise, which cannot reflect students' aerobic endurance," Ji said.

The move in Shanghai follows the deaths of two college students in Guangdong province and one in Shanghai after long-distance runs in November. Several colleges and middle schools canceled long-run projects in their sports contests after the deaths.

20米折返跑试点在上海18所学校,约5000名学生中进行。折返跑即是在20米距离的两点,加速往返跑。“以测试女子800米、男子1000米来衡量学生的有氧耐力,本身就不够科学。”华东师范大学“青少年健康评价与运动干预”教育部重点实验室季浏教授,也是这个试点项目的领导,告诉记者:"从科学和生理学的角度来看,长跑属于有氧与无氧运动的结合,并不能科学地测出学生心肺功能,跑步速度跟学生的身体机没太大关联,长跑也不能反映有氧耐力。上海的这个举动的背景是:去年11月份广东两名和上海一名大学生在长跑中猝死,几个大学和中学此后取消了长跑项目。

【讲解】
在aerobic 里,aero-这个词根来源于希腊文,表示“空气”的意思。例如:飞机更为正式的表达是aeroplane,后来嫌长,就简称plane。而前面再加个an-这个同样源自希腊文表否定的前缀,anaerobic 意思就是“无氧”了。

  • no matter what type of running, the point is health,right?

  • they should rather do the opposite by applying long-distance track activities to elementary schools (e.g. 200-400 to start with and then increase as age increases) so that kids won't be so unprepared for the activities in the future. Unless having cardiovascular problems (should be accompanied by medical statement), young people should not die from running merely 1000m... this only shows that people today don't have the proper stamina for their age, which means the vast majority is not healthy enough. This is the sad side effect of information age....

  • actully,we all know it's useless if we do some exercise only in order to cope with the PE test.A continue training is efftive.anything can not be really success without accumulate day by day and month by month.
