摘　　要：以641名普通大学新生(男生350名,女生291名)为实验对象,按照中国肥胖问题工作组对中国成人体重指数(BMI)分类标准进行分组,通过对D/S比值和心率的对照研究。结果表明,在静息状态下,体重正常组学生与其他组学生的D/S比值和心率均存在显著差异。结论:BMI值与D/S比值和心率之间有密切关系,BMI正常的学生比BMI偏高或偏低的学生具有更高水平的心脏储备。641 ordinary college freshmen are taken as research subjects and classified into different groups according to the BMI level. The heart sound signals are collected to conduct a comparative research into the D/S value and heart rate. Research findings indicate that in the state of quiet breathing, the D/S value and heart rate of students in the normal weight group are markedly different from those of students in other groups. It is concluded that BMI index and D/ S value and heart rate are closely related and students with normal BMI index have higher heart storage ability than those of abnormal BMI index.
