There is some controversy as to the fitness levels of U.S. school-age youth. Some experts claim that U.S. youth are fit. Others feel that there has been a decline, despite a recent adult fitness boom.
The purpose of this article is to examine the research conducted on the cardiovascular endurance and body composition levels of U.S. youth. Research studies noting the activity patterns of youth outside and during physical education are presented. The frequency and duration of physical education requirements are also reviewed. The effects of these patterns and requirements on cardiovascular endurance and body composition are presented.
U.S. youth do not engage in physical activity, within our outside physical education, sufficient to develop cardiovascular endurance. Our youth are, therefore, at risk of developing a myriad of diseases associated with sedentary lifestyles.
Exercise is known to have a prophylactic effect on disease, death, and disability. Young people must be instructed and encouraged to be involved in lifetime fitness activities if we are going to control health care costs, reduce disease incidence, and improve the overall quality of life of our citizens.
关于美国学龄青少年的健康水平存在一些争议。一些专家声称美国青少年身体健康。另一些人则认为，尽管最近成年人健身热潮兴起，但青少年的健康水平却有所下降。
本文旨在研究关于美国青少年心血管耐力和身体成分水平的研究。文中呈现了记录青少年在课外和体育课期间活动模式的研究。还回顾了体育教育要求的频率和时长。阐述了这些模式和要求对心血管耐力和身体成分的影响。
美国青少年在课外或体育课上进行的身体活动不足以发展心血管耐力。因此，我们的青少年有患多种与久坐生活方式相关疾病的风险。
众所周知，运动对疾病、死亡和残疾具有预防作用。如果我们要控制医疗成本、降低疾病发病率并提高公民的整体生活质量，就必须指导和鼓励年轻人参与终身健身活动。
