Several studies have shown that decreased muscle weight is a risk factor of elderly disease. The aim of the present study is to evaluate the relation between muscle weight and bone mineral density and physical fitness in elderly women. Seventy three elderly women(aged 67.5 ± 3.6 yrs) were evaluated and divided according to their muscle weight level in quartiles. Subjects were divided as follows: Quartile 1 (Q1; <32.9 kg; n=18), Quartile 2 (Q2; ≥33.0 and <35.6 kg; n=18), Quartile 3 (Q3; ≥35.7 and <37.0 kg; n=18), Quartile 4 (Q4; ≥37.2 kg; n=19). Body composition, bone mineral density(BMD) and basal physical fitness were compared between four groups according to muscle weight levels. Body muscle weight was measured by using body composition analyzer(Inbody720, Biospace, Korea) and BMD of the total body was also measured by using dual energy X-ray absorptiometry(DEXA). Pearson"s correlation coefficient and level of significance were used to evaluate the correlations between measurements. There were significant differences for height and weight according to quartiles of muscle weight level, respectively(p<.001), and BMI and %BF also significantly increased in the order of Q1, Q2, Q3, and Q4 group(p<.001). BMD of Q2, Q3, and Q4 group were significantly higher than that of Q1 group(p<.001), BMC of Q3, and Q4 group were significantly higher than that of Q2 group(p<.001) and that of Q2 group were also higher than that of Q1 group(p<.001), Most of basal physical fitness showed no significant differences among quartiles of muscle weight level(NS). Age was negatively correlated with total BMD, T??score and total BMC, respectively(p<.05), and height, weight, BMI and muscle weight showed a positive correlations with most of BMD and BMC, respectively(p<.05, p<.01). A negative correlation was found between weight and 2min walking and chair sit & reach, respectively(p<.05), and BMI showed negative correlations with back scratch and one leg stand, respectively(p<.05). %BF was negatively correlated with chair sit & reach and one leg stand, respectively(p<.05, p<.01). These results suggest that decrease of muscle weight result in reducing of BMD, and osteoporosis is occur by this reducing of BMD in elderly women. Moreover, the keep of muscle weight through the maintain body composition such as weight and BMI is beneficial to maintain BMD of elderly women.
