体质指数与心肺功能的增龄性变化及相关性研究

目的:研究体质指数(BMI)与心肺功能的增龄性变化特征,探讨二者的相关性。方法:以江苏省参加2011年国民体质监测的418名受试者为研究对象,使用身高体重计和功率自行车测试受试者的身高、体重、心脏功能能力和最大摄氧量等指标,研究不同性别BMI、心脏功能能力和最大摄氧量等指标的增龄性变化特征,分析BMI与性别、年龄、心脏功能能力和最大摄氧量等指标的相关性。结果:(1)男性BMI值的峰值出现在20-30岁年龄组,女性在该年龄段的BMI值则为谷值,男女性心脏功能和最大摄氧量的峰值均出现在30-40岁组年龄组,男女性BMI值、心脏功能和最大摄氧量三指标均在40-50岁组呈现不同程度的功能衰减趋势;男性BMI值、心脏功能和最大摄氧量三指标值均大于同龄组女性。(2)性别、年龄、心脏功能能力、最大摄氧量与BMI的相关度均较低,性别与BMI的关系是显著的(P<0.01)。(3)对机体进行适时的有氧运动干预可以有效地改善或提高人体的BMI和心肺功能。结论:在40-50岁进行长期的有氧运动干预可更为有效地改善或提高男女性的BMI和心肺功能。

Age-Related Changes and Relationships of BMI and Heat and Lung Funtion

Aim: The aim is to examine the age-related changes and relationships of BMI and Heat and lung funtion.Methods: Total 418 people of particioate in the Jiangsu national physique monitoring in 2011years.Use of height and weight and power cycling test subjects’ height,weight,cardiac fuctiongal capacity and maximal oxygen uptake index.Study of different gender BMI,cardiac functional capacity and maximal oxygen uptake and other indicators of age-related changes in the characteristics.Analysis of BMI and gender,age,heart function and VO2max index correlation.Results:(1) The male BMI value peak value appears in the 20 to 30 age group.Women in the age of BMI value for the valley value.Male and female cardiac function and VO2max peak appeared in 30-40 years old group of age group.Male and female BMI,cardiac function and maximal oxygen uptake of three indicators in 40-50 years old group showed different degrees of functional attenuation trend.The male BMI,cardiac function and VO2max three index values were greater than peers in the group of women.(2) Gender,age,cardiac functional capacity,maximal oxygen uptake and BMI correlation degree are low.Gender relationship with BMI is remarkable(P<0.01).(3) On the timely intervention of the aerobic exercise can effectively improve or enhance human BMI on the function of heart and lung.Conclusion:Attenuation of apparent period are able to more effectively provide for raising and minimizing the loss of BMI and Heat and lung funtion between 40 and 50 years old.
