工业化国家的儿童显然长期处于能量摄入过多的高度危险状态,部份由于习惯坐着的生活方式所致,包括长时间地看电视。这种能量的过剩导致肥胖及在中年人成为发生冠心病和各种癌症的重要危险因素。对童年期的冠心病危险因素的最新研究表明,肥胖指数如Quetelet指数(体重/身高~2)、皮折厚度与幼年时期舒张压、脂蛋白含量之间有显著的相关。通过对学校每日体育活动的安排,已有可能减轻这些危害儿童健康的因素。法国、比利时、加拿大等国对学校体育活动效果研究很多,已有对体格、心理和学习效果等各方面的报导。然而这些研究没有设立恰 Children in industrialized countries have apparently been at a highly dangerous long-term energy overload, partly due to the habitual sitting lifestyle, including prolonged television viewing. This excess of energy leads to obesity and an important risk factor for coronary heart disease and various cancers in middle-aged people. Recent studies on childhood coronary risk factors have shown that obesity indices such as the Quetelet index (body weight / height ~ 2), skin fold thickness have a significant association with diastolic blood pressure and lipoprotein content in infancy. Through the arrangements for daily school sports activities, it has been possible to mitigate these factors that endanger the health of children. Many countries such as France, Belgium and Canada have studied the effect of physical activity in schools and have reported on physical, psychological and academic effects. However, these studies have not been established
