  • This study sought to reduce the risk of fractures in elite youth taekwondo athletes to find out the relationship between bone mineral density which are used as indicators of early diagnosis of osteoporosis and cardiorespiratory functional capacity which is an indicator of performance and sports injury the harmful to athletes. The Pearson product-moment correlation was performed to investigate the correlation between bone mineral density, cardiorespiratory functional capacity, and sports injury. The bone mineral density and cardiorespiratory functional capacity, sports injury were examined the relationship using the Simple Linear Regression. The bone mineral density were correlated with the ventilation (r=.388), and VO2max (r=.478). Bone mineral density was correlated with sports injury (r=-.292). When the bone mineral density increased by .002 and .006, the ventilation (p=.001) and VO2max (p=.006) increased by about 1. In addition, when the bone mineral density decline by .016, the sports injury increased by about 1. Improving athletes' bone mineral density can prevent sports injury, and it can be used as a sports injury prevention program in the future.

  • We investigated the age-related BMD, accumulated bone loss rate and peak BMD at Lumbar spine, total hip in Korean using data from KNHANES (the 1st(2010), 2nd(2011) and year at the 5th survey). We found that the cubic regression model was the best for describing age-related changes in BMD. Lumbar spine, total hip in bone mineral density difference were analyzed using ANOVA. This showed that the peak BMD was at the age of 20-24 years at lumbar spine, total hip and the bone loss rate was the highest in the lumbar spine at 75-79 years and the total hip was 80 years or older in the men. This showed that the peak BMD was at the age of 40-44 years at lumbar spine, total hip and the bone loss rate was the highest in the lumbar spine at 70 years or older and the total hip was 75-79 years older, 80 years old, 55-59 years old in the women. Therefore, in men, 75 years or older to increase the rate of osteoporosis screening, and women in their 50s and older menopause related management strategies to manage osteoporosis will be needed.

  • The aim of this study was to determine the factors affecting the Bone Mineral Density (BMD) on Premenopausal Women. This study made use of the data from the Fifth Korea National Health and Nutrition Examination Survey (KNHANES V-2, 2011). The results are as follows. The factors with an effect on the bone mineral density (BMD) were the body mass index, age, and walking exercise. These factors explain 11.7% of the variance in the BMD. In addition, the bone density of people in their 20s was lower than those in their 50s. Walking exercise for less than 3 days showed that the BMD had decreased significantly. In conclusion, to maintain a normal BMD on premenopausal women, it is important to avoid an excessive diet and recognize the correct body image. These results suggest that education programs including the appropriate diet and lifestyle should be developed for women in their 20's.

  • Purpose: This study examined the effects of combined intervention of isoflavones and exercise on bone mineral density, bone mineral content, and biochemical bone markers. Methods: Forty rats were divided into four groups; Control, Isoflavones (IF), Isoflavones + Running (IFR), and Isoflavones + Swimming (IFS). All of the rats in this study were fed an experimental diet and deionized water ad libitum for nine weeks. Bone mineral density (BMD) and bone mineral content (BMC) were estimated using PIXImus (GE Lunar Co, Wisconsin.) in spine and femur nine weeks after feeding or training. Results: The combined intervention did not affect weight gain, mean food intake, or food efficiency ratio. The serum concentrations of ALP and osteocalcin were not significantly different by combined intervention. The urinary DPD crosslinks values were not significantly different by combined intervention. There were no significant differences in serum PTH, calcitonin, and estradiol among all groups. Spine BMD, spine BMC and femur BMC were not significantly different by combined intervention. However, femur BMD was significantly higher in the IFR group than in the control group. Compared with the control group, spine BMD, spine BMC, and femur BMD per weight were markedly increased in the isoflavones supplementation and combined intervention group. In addition, femur BMC per weight was significantly higher in the IFS group than in the control group. Compared with the isoflavones supplemented group, BMD and BMC were not significantly different by combined intervention. Conclusion: It can be concluded that isoflavones supplementation or combined intervention of isoflavone and exercise had a beneficial effect on spine and femur peak bone mass in growing female rats.

  • This study examined the distribution of bone mineral density(BMD) and the von Mises stress in the patella. The BMD of eighteen patellae were determined by using quantitative computed tomography and imaging analysis software. It was found that the BMD of the patella varied with location. BMD values were largest at the superior and lateral regions and decreased inferiorly and medially. This distribution appeared to correspond to the organization of trabeculae within the patella. A two-dimensional finite element analysis was performed on each patella. It was also found that the maximum von Mises stress in the patella occurred along the cortical shell on the non-articular surface. The trabecular von Mises stress existed in the posterior region of the patella. These findings demonstrated the potential for finite element studies in vivo. Further, such studies may lead to the development of custom-made, patient-specific patella prostheses.

  • This study examined the age-related bone mineral density (BMD), accumulated bone loss rate (ABLR) at different skeletal sites in Korean men using the data from the Korea National Health and Nutrition Examination Survey (KNHANES)(the 1st (2010), 2nd (2010) and the year at the 5th survey). The cubic regression model was found to be the best for describing the age-related changes in BMD. The lumbar spine, total hip, femoral neck, trochanter, Ward's triangle in the bone mineral density difference were analyzed by ANOVA. The peak BMD was at 20-24 years at the lumbar spine, total hip, femoral neck, trochanter, Ward's triangle, and the 75-79 years of age group had the highest Accumulated Bone Loss Rate. Therefore, intensive management will be necessary for men over 75 years, and a diagnosis of osteoporosis in Korean men should be made according to The International Society for Clinical Densitometry; ISCD.

  • In this research, we have analyzed the impact factors on the bone mineral density thru the examination of bone density difference in the entire femur, femoral neck and lumbar of adult women before the menopause in accordance with the general features, lifestyle, eating habits, health and body composition. The survey was conducted among adult women before the menopause and older than 30 years based on the data of the National Health and Nutrition Examination Survey carried out in the 4th term (2008-2009) and 5th term (2010-2011) and we would like to provide the research results for the establishment of recommendations or guidelines for the treatment of adult women before the menopause with regard to the impact factors on the bone mineral density and for the development of health education materials for the accurate measurement of bone mineral density of young women in order to prevent the postmenopausal osteoporosis. With respect to the general features of adult women before the menopause, the bone mineral density was higher in the entire femur at age 40-44, femoral neck at 35-39, in high-school education level, in the earlier menarche group, without smoking experiences, with regular walking time and exercise frequency and with the habits of eating no hamburger or pizza. With regard to the body composition, the bone mineral density was higher in obesity and lower in underweight cases, higher among people with abdominal obesity and weight control experiences. In terms of total body fat ratio, total amount of fat and muscle, the bone mineral density got gradually increased from the 1st quarter (Q1) to the 4th quarter(Q4). The obesity, disease, total amount of fat and muscle were shown to be significantly related with the bone mineral density in this research and it is required for young women to keep the adequate weight and the normal BMI in order to increase the bone mineral density. For the prevention of osteoporosis, it is advised to keep the right habits including regular exercise and no smoking discipline from the growing period and achieve the maximum bone mass thru the control of proper weight from a young age.

  • Dual Energy X-ray Absorptiometry(DEXA) is commonly used to diagnose Osteoporosis. The errors of DEXA bone density operation are caused by operator, bone mineral density meter, blood testing, patient. We focus on operator error then study about how much influence operator's region of intest(ROI) in bone testing result. During from March to July in 2011. 50 patients ware selected respectively from 30, 40, 50, 60, and 70 age groups who came to Korea University Medical Center(KUMC) for their Osteoporosis treatment. A-test was performed with usually ROI and B-test was performed with most widely ROI. Then, We compare A-test and B-test for find maximum difference of T-score error which occurred operator ROI controlling. Standard deviation of T-score of B-test showed 0.1 higher then A-test in femur neck. Standard deviation of B-test showed 0.2 higher then A-test in Ward's area which in Greater trocanter and Inter trocanter. Standard deviation of B-test showed 0,1 lower then A-test in L-1. Bone density testing about Two hundred patients results are as follow. When operator ROI was changed wider than normal ROI, bone density of femur was measured more higher but bone density of L-spine was measured more lower then normal bone density. That means, sometime DEXA bone density testing result is dependent by operator ROI controlling. This is relevant with the patient's medicine and health insurance, thus, tester always keep the size of ROI for to prevent any problem in the patient.
