测量跳远全程助跑距离和步点的方法一般有哪两种?

答案

参考答案:

(1)在跑道上用自己确定的助跑开始姿势和加速方式做30~40米的跑,反复几次之后,找出从起跑点到自己确定步数的脚迹(如果脚迹不在一点上,可以取多次脚迹相对集中的点),然后用皮尺丈量出这段距离,再把它移到跳远助跑道上。

(2)在跳远助跑道上,以起跳板为起点,沿助跑反向按自己确定的助跑开始姿势、加速方式和步数反复跑几次,找出多次脚迹的相对集中点,再以这点为起跑点,按原助跑方式向起跳板方向助跑并起跳。

     These days, people are concerned about the growing number of kids who are overweight.

Do you know why? Kids know it's a problem, too. We recently asked 1, 168 boys and girls about

the problem.  More than half of them (52%) said that too many kids were overweight.

    "This is important because knowing there is a problem is the first step to solve the problem," said

Dr Sandra Hassink, a doctor in Delaware who helps kids with weight problems.

     What does "overweight" mean? Most people who are overweight have too much body fat. The

person who is overweight weighs more than a healthy person, considering age, height, and whether

the person is a boy or a girl.

     When asked why some kids were overweight, many of the kids (54%) said it was because

overweight kids didn't exercise enough or eat right. Others said that kids were overweight because

fast food restaurants served the wrong foods.

     The research also asked the kids some questions about themselves. Most of the group (78%) said

they were either the right weight or underweight. The rest of the group thought they were overweight,

with 4% of the kids saying that they were very overweight.

     The research results don't prove that 4% of the kids were very overweight, but it shows that 4%

of the kids believed they were overweight and answered in that way. On top of that ,54% of the kids

said they worried or stressed out about their weight, with more girls feeling in this way. Of those who

 said they never worry about their weight, 59% were boys and 33% were girls.
