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.
