公园使运动更给力
啊，超赞的户外运动，对身体也有好处哦。因为研究表明，我们经常逛逛街边公园，身体会越来越健康。
为了为美国游憩与公园协会准备一篇报告，来自美国宾州州立大学的研究员处理了来自各种研究的数据。
在五个城市的调查中，38%超过50岁的人称他们每周至少去一次公园。所以这些绿洲不仅只是个美丽的地方，也是个健身的好去处。
年轻人同样也会受益。一研究表明，青春期女生会在每周去距家半米以内的公园做17分中强度到高强度的体育运动。此外，在公园和娱乐场所方面，政府为每人每多投资10美元，女生每周进行高强度运动的时间就会多8小时。此政府花销同时也为男生女生带来更多的塑形锻炼。
如此一来，每人每年就能减少至少8000美元的医疗保健费用。所以，政府官员在想着紧缩预算的时候要三思，是否要节省公园建设费用以减少财政预算。因为逛公园真的让我们减肥了。
