Participation in physical activity on a regular basis provides important health benefits, including reduced risk for heart disease, colon cancer, diabetes, and high blood pressure. Regular physical activity also helps control weight; contributes to development and maintenance of healthy bones, muscles, and joints; and reduces symptoms of anxiety and depression. Recent recommendations have emphasized moderate intensity activities nearly every day for those who are unable to maintain the previously recommended program of strenuous activity three times a week. To determine the proportion of adults who are participating in regular physical activity, regardless of the level of intensity, CDC analyzed data from the 1994 Behavioral Risk Factor Surveillance System (BRFSS). This report summarizes the results of that analysis, which indicates that, in every state surveyed, most adults are not participating in regular physical activity.
经常参加体育活动对健康有诸多重要益处，包括降低患心脏病、结肠癌、糖尿病和高血压的风险。定期进行体育活动还有助于控制体重；促进健康骨骼、肌肉和关节的发育与维持；减轻焦虑和抑郁症状。最近的建议强调，对于那些无法维持此前每周三次剧烈运动建议方案的人，几乎每天都应进行中等强度活动。为了确定参与定期体育活动的成年人比例，无论强度如何，美国疾病控制与预防中心（CDC）分析了1994年行为风险因素监测系统（BRFSS）的数据。本报告总结了该分析结果，结果表明，在每个被调查的州，大多数成年人都没有参与定期体育活动。
