沈阳市初中生日常体力活动水平与其循环 和代谢性指标的关系研究 运动人体科学专业 郭 琪 指 导 教 师 衣雪洁 摘 要：目的:为了探明青少年体力活动水平与其循环和代谢性指标的关系，为推荐青少年日常体力活动标准提供理论依据。方法:采用GT3x活动监测器监测沈阳市某学校12-16岁青少年共163人日常体力活动水平，并测量其循环和代谢性指标，即安静心率、收缩压、舒张压、血红蛋白、血糖、血清总胆固醇（TC）、甘油三酯（TG）、高密度脂蛋白（HDL）以及低密度脂蛋白（LDL）含量。运用双变量相关分析对日常体力活动水平与各指标进行相关性分析。结果:HDL与平均每日步数相关系数R=0.201，P＜0.05，有统计学意义，HDL与工作日每日平均步数相关系数R=0.283，P＜0.01，有统计学意义，HDL与周末日平均每日步数相关系数R=0.148，P＜0.05，有统计学意义。其他代谢指标和评定循环机能指标与平均每日步数的P值均＞0.05，没有统计学意义。结论: 青少年时期的在校学习日的体力活动和平时的体力活动能有效降低心血管疾病的风险。心率血压和其它血液代谢指标对体力活动步数的相关性不敏感.建议：1.将HDL做为评价青少年体力活动防控心血管疾病的敏感指标。2试验指标阴性结果可能与样本量小有关，建议增大样本量。 关键词：青少年；体力活动水平；循环、代谢性指标 The Correlation between Daily Physical Activity and Circulation and Metabolism Indices in Teenagers of Schools in Shenyang Abstract: Purpose: To explore the relation between teenagers’ physical activity level and their circulation and metabolism indices to provide theoretical evidence for recommending teenagers’ daily physical activity standard. Method: GT3x activity monitor was used to monitor the physical activity levels of 163 teenagers of schools in Shenyang. Their circulation and metabolism indices were also tested， including resting heart rate， systolic?and?diastolic?blood?pressure， hemoglobin， blood glucose， serum total cholesterol (TC)， triglyceride (TG)， high density lipoprotein (HDL) and low density lipoprotein (LDL). Bivariate?correlation?analysis?was used?to?analyze?the relationship between physical activity level and the indices. Results: HDL has significant correlation with average daily steps， working days’ average daily steps and weekends days’average daily steps. (R=0.201， P=0.016; R=0.283， P=0.001;R=0.148，P=0.041); other indices has no significant correlation with average daily steps. Conclusion: teenagers daily physical activity can effectively reduce the risk of cardiovascular disease. Heart rate、 blood pressure and other blood metabolic index is not sensitive to the average daily steps.suggustion:1.HDL as a sensitive index to evaluation adolescent
