Articles : The Relationship Between Body Composition, Bone Mineral Density and Resting Metabolic Rate in Young Female
This study to investigate whether co-relationship with muscle mass and bone mineral density (BMD) used the whole body scan by DEXA method in young female. Moreover, we investigated co-relationship with resting metabolic rate(RMR) used MedGem (Small oxygen analyzer) and muscle mass. BMD is in general known as the weight positive relationship, however the correlationship between the weight and BMD did not exit in this study. On the other hand, BMD and muscle mass showed positive relationship (r=0.433, p<0.01). Also, We would suggest that RMR was in proportion to muscle mass. And, body fat (%) did not have positive relationship, but showed reverse relation (r=0.204) statistically. Therefore, resistance training to increase muscle mass are desirable in obesity and osteoporosis prevention that intimidated health of modern people most. Also, enough intake of protein to increase muscle mass is important.
Key Words: dual energy X-ray absorptiometry, DEXA, bone mineral density, BMD, resting metabolic rate, RMR, body fat, muscle mass
