The positive influence of physical activity on chronic disease has been well established for the adult population. Much less is known about the relationship between physical inactivity and risk factors for coronary heart disease in children. It has not been clearly established how active children are, nor do we know the factors that determine physical activity patterns among youth. The purpose of this brief review is to describe different techniques used to assess physical activity that are consistent with the operational definition of physical activity. Descriptive information from the National Children and Youth Fitness Studies related to children's level of physical activity is provided which indicates that children are physically active. Nevertheless, it is suggested that the importance of regular physical activity should be emphasized to our youth to promote lifetime activity participation for long-term health and well-being.
体育活动对成年人群慢性病的积极影响已得到充分证实。关于儿童缺乏体育活动与冠心病危险因素之间的关系，我们了解得要少得多。目前尚未明确儿童的活动量究竟有多大，我们也不清楚决定青少年体育活动模式的因素。本简要综述的目的是描述用于评估体育活动的不同技术，这些技术与体育活动的操作定义相一致。文中提供了来自全国儿童和青少年健康研究的与儿童体育活动水平相关的描述性信息，这些信息表明儿童是积极参加体育活动的。然而，建议应向我们的青少年强调定期体育活动的重要性，以促进他们终身参与体育活动，从而实现长期的健康和幸福。
