Overweight.
Out-of-shape.
Fat.
Whatever you want to call it, many studies show that children around the world are becoming less active and less physically fit. The result is an increase in obesity, the condition of being severe overweight, also diabetes and other diseases.
It is a major concern for public health officials. And it may be that fitness levels affect more than physical health. For students, it may also affect test scores.
VOA's Carol Pearson was in Redondo Beach, California, recently with more than 700 children. They were walking to school with parents and, in some cases, even their dogs. The students do this once a week. The children may not know it but they walk to help reduce childhood obesity. It is also meant to increase their activity, or fitness, level.
"It's a good way to get the kids exercising in the morning."
For the kids, it's just fun.
"I like walking to school with my friends."
"One of my friend's name is Elissa. And we talk about a lot of things at school. We talk about how hard our homework is and all of the fun activities we're doing."
A study from the U.S. Centers for Disease Control and Prevention shows that most American children are physically unfit. But, children in other countries also face this problem.
Health officials across the world are concerned about rising rates of obesity and type 2 diabetes in children as young as eight. This kind of diabetes is directly related to poor diet and lack of physical activity.
Kids need an hour of exercise daily.
The World Health Organization advises that children between the ages of five and 17 get at least 60 minutes of physical activity every day. The activity should be moderate to very energetic, or vigorous.
Studies on children and exercise show that fitness is good for more than just physical health.
A U.S. Institute of Medicine study shows that physical activity helps students with their studies. Harold Kohl led the study. He is a professor of epidemiology at the University of Texas. He researches how diseases spread among populations.
"The evidence is really emerging in the last five or six years. Both cognitive studies, as well as brain imaging studies and others, show the acute effects that a bout or two of physical activity on blood profusion in the brain. It is in the center that really help children learn, recall things faster, think faster and actually are more likely to achieve their full academic potential compared to children who are not physically active."
A University of Illinois study shows similar results. Professor Charles Hillman talked to VOA on Skype. Mr. Hillman says children in his study who had physical activity on a usual basis improved in school. He also says children learn best if physical activity is included during class time or before.

不管用什么说法，很多研究都发现全世界的儿童的活动量在减少，身体素质也在下降。其结果就是肥胖增加，也就是严重超重，以及糖尿病等疾病。
公共健康官员对此非常担忧，这种健康水平不及影响身体素质，对学生来说，还可能影响考试成绩。
美国之音的卡罗·皮尔森在加州雷东多海滩，他最近和700多名儿童在一起。他们和父母一起走路去学校，有时还带着小狗，他们每周一次这样做。孩子们可能还不知道，这样的行走能帮助减轻儿童肥胖，也意味着增加活动性和健康水平。
“这是让孩子们早上锻炼的好办法。”
对孩子们来说，这样也很有趣。
“我喜欢和朋友们走着去上学。”
“我有个朋友叫艾丽莎，我们在学校谈论很多事，我们谈论家庭作业多么难，还聊我们做的所有有趣的活动。”
美国疾病控制和预防中心的研究表明，大多数美国儿童身体不够健康，但其他国家的儿童也面临这一问题。
全世界的医疗工作者都对儿童肥胖率和二型糖尿病率的增高表示担心，有的儿童8岁就出现这一问题。这种糖尿病直接与营养不良和锻炼少有关。
世卫组织建议5到17岁的儿童每天至少锻炼60分钟，这些活动应该适度，也可以是很激烈的运动。
对儿童和锻炼的研究表明，健康不仅对身体有好处。
美国一家医学研究所的研究表明，身体锻炼能帮助学生提高成绩。哈罗德·科尔是这项研究的负责人，他是德克萨斯大学流行病学教授，他研究疾病如何在人与人之间传播。
“过去至少五、六年的证据很多，无论是认知学习，还是大脑图片学习等都表明一两项锻炼活动对大脑血液灌注的影响，锻炼真的能帮助孩子更快地学习和回忆，让他们思维更敏捷，与那些不活动的孩子相比，他们更容易发挥全面的学业潜力。”
伊利诺州大学的研究结果与此类似，查理斯·希尔曼教授通过Skype接受美国之音的采访。
希尔曼说在他的研究中，做锻炼的孩子通常学业成绩会提高，他说如果在课间或上课前进行锻炼，孩子的消息效果会更好。
