Association of Cardiorespiratory Fitness with Insulin Resistance, Blood Lipids and Bone Mineral Density in Young Female Adults / 대한스포츠의학회지

ABSTRACT

Whether cardiorespiratory fitness is associated with insulin resistance, blood lipids, and bone mineral density remain less clear. The purpose of this study was to investigate the relationship between cardiorespiratory fitness and insulin resistance, blood lipids, and bone mineral density in young female adults. Twenty-two female adults (body mass index: 21.62+/-2.23, age: 20.05+/-1.81) participated in this study. Harvard step test was assessed, and fasting glucose, insulin, total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), triglyceride (TG) and bone mineral density (BMD) were measured. Pearson product-moment correlation, partial correlation, simple linear regression and Dubin Watson test were used to investigate the association of cardiorespiratory fitness with insulin resistance, blood lipids and BMD to examine the statistical significant. Cardiorespiratory fitness was significantly associated with LDL-C, insulin, T-score and insulin resistance, respectively. In conclusion, young female adults who have lower level of cardiorespiratory fitness were more likely to have higher LDL-C and insulin and lower BMD and insulin resistance. This study suggests that not only prevention of obesity but also promoting cardiorespiratory fitness and bone density are important for the health of young female adults.
