Correlations between Body Composition Components and Bone Mineral Content in Untrained Young Men and Women
<p>PURPOSE: Low bone mineral content has been linked to the development of osteoporosis in humans. Research is divided as to whether fat or lean mass plays a more significant role in the development of bone mass. Physical activity has also been shown to increase bone mineral content in adolescents …

The Influence of Physical Activity on Bone Mineral Content in Women Over Eighteen Years of Age
The influence of physical activity on bone mineral content was investigated in 299 normally healthy, Caucasian women, aged 19 to 91 years. It was hypothesized that the more active women have a greater bone mineral content than their less active peers, and that body composition, skeletal size and …

Body composition in elderly and its features in persons with sarcopenia /
… of all the skeletal muscle mass and later the bone mineral content – reduces and the fat mass increases, also the regional re-distribution of fat mass occurs. The combination of low muscle mass and low muscle strength or physical performance is called sarcopenia. The aim of this study was to …

Carbohydrate and Fat Supplementation in Grazing Mares and Foals
… examined using growth measurements, radiographic bone evaluations, milk composition and glucose tolerance tests. These studies suggest that fiber may be an important component of an ideal supplement for improved grass/legume pastures. Seasonal variation in pasture indicated an increase in …

Effect of isokinetic resistance training on ulnar stiffness in young, college-aged women
Bone mineral content (BMC) and bone mineral density (BMD), measured by dual x-ray absorptiometry are used clinically to diagnose osteoporosis and estimate risk for fragility fractures. Bone mineral explains up to 70% of bone strength; however, it does not take into account bone geometry. Mechanical …

Calcium Requirement Distribution Via Bone Growth Modeling
… focuses on estimating calcium requirements using bone growth data in adolescents. We estimate the peak rate of growth of bone and the variability of this peak growth rate to provide Dietary Reference Intakes (DRIs) for calcium. The specific DRIs of interest are Estimated Average Requirement (EAR) …

Physical Activity, Estrogen Replacement Therapy and Bone Mineral Density in Early Postmenopausal Women
… of high and low levels of physical activity on bone mineral content (BMC) and bone mineral density (BMD) was investigated in 60 healthy, Caucasian, early postmenopausal women. All women examined were a minimum of two but no more than five years past natural menstrual cessation. Subjects in the …

The effect of continuous infusion of human parathyroid hormone on bone architecture in female mice
… for either 2 week or 4 week duration. Total body bone mineral density (BMD) and bone mineral content (BMC), trabecular and cortical bone microarchitecture, and serum calcium levels were measured. There were no significant differences in BMD or BMC in either study in mice infused with either …

Identification, Prevention and Treatment of Children with Decreased Bone Density
… in children is the presence of low bone mineral content or decreased bone mineral density with a significant fracture history. The future economic consequences and quality of life issues associated with osteoporosis are considerable, justifying this skeletal disorder as a public …

Bone health and fracture risk among peripubertal and adolescent children. Importance of body weight, distribution of adipose tissue and the presence of metabolic abnormalities // Костно здраве и фрактурен риск сред деца в перипубертетна и юношеска възраст – значение на телесното тегло, разпределението на мастната тъкан и наличието на метаболитни отклонения
… is an active participant in the regulation of bone homeostasis, and obesity is a new and recently recognised potential risk factor for disorders in bone strength. The current study includes a survey of the number and localisation of fractures suffered so far among 2513 schoolchildren in the …

Metabolic changes to GLUT-4 levels in urban Chacma baboons on the Cape Peninsula: raiding their way to type 2 diabetes?
… total body lean mass (kg) (p<0,01) and bone mineral content (kg)(p<0,001) than the wild-‐feeding controls. These results indicate that male individuals from the Peninsula population are bigger but not fatter than wild-‐feeding male baboons from the Eastern Cape population. Although it …

The Effects of Chronic Prophylactic Naproxen Sodium on Skeletal Muscle Adaptation to Resistance Exercise in Recreationally-Trained College-Aged Males
… arm lean and fat tissue, and non-dominant arm bone mineral content. No significant treatment effects were detected for any dependent variables, thus twice weekly naproxen sodium (440mg) does not appear to inhibit skeletal muscle adaptation to resistance exercise in recreationally-trained …

Changes in BMD and Body Composition in Children with Central Precocious Puberty Before and After Treatment with GnRH Agonist
"We assessed bone mineral density (BMD) and body composition in 121 Korean girls with central precocious puberty (CPP) before, during, and after 1 year of treatment with gonadotropin-releasing hormone (GnRH) agonist. BMD, bone mineral content (BMC), lean body mass (LBM), and fat mass (FM) were …

The impact of dynamic and passive standing on bone mineral density and appositional growth in immobilized children
… loading has on determining the strength of bone occurred in 1892. However, for almost a century after this discovery, the specific mechanisms influenced by mechanical loading remained locked in a mysterious 'black box'. Then in the 1960s, the 'black box' was opened and continued work has now …

The Safety and Adequacy of Galactooligosaccharides and Fructooligosaccharides in Infant Pig Formula
… 0.001) indicated a smaller rate of accretion in bone mineral content for soy-based diets. Total bacteria and lactobacillus were significantly affected by treatment (P < 0.001). In conclusion, the addition of GOS and FOS to formula does not appear to alter growth however, the gut microbiota was …

Muscular Strength Training Modifies Regulation of Bone Remodeling: Inferences From Serum Biomarkers in Young Women
Biochemical markers of bone turnover allow inference of the events occurring at the bone tissue level and may detect changes in bone cell activity earlier than densitometric technologies. Serum concentrations of receptor activator for nuclear factor kappa-beta ligand (RANKL), osteoprotegerin (OPG), …

Identifying a non-invasive measure of bone status in dairy cattle
… were to evaluate non-invasive measures of bone mineral content (BMC) and bone mineral density (BMD) as rapid, on-farm tools to assess phosphorus (P) status in dairy cows. In addition, the effects of parity and stage of lactation on measures of BMC of the fused 3rd and 4th metacarpal bone …

The Relationship between Lower Extremity Bone Mass and Body Mass Index in a NHANES Adolescent Population
<p>The effect of body mass index (BMI) on bone mineral content (BMC) among adolescents has been researched yielding mixed results. This study explored the relationship of left lower extremity (LLE) BMC on BMI across the spectrum of weight in a large nationally representative group of adolescents. …
