Bone mass, bone mineral density and muscle mass in professional golfers
Journal of Sports Sciences, 2002The aim of this study was to determine the effects of long-term professional golf participation on whole-body and regional bone mass and density. Dual-energy X-ray absorptiometry was performed on 15 male professional golfers and 18 sedentary individuals, matched for sex, race, age (29+/-1 and 25+/-1 years, respectively), body mass (79+/-2 and 74+/-2 kg)

The overall role of exercise as an integral part of osteoporosis prevention and treatment remains unclear and controversial. Comparatively well accepted are the facts that disuse results in bone mass loss, that sedentary individuals in general have less bone mass than exercising individuals (from cross-sectional study data), that exercise may produce a

Genetic Determinants of Bone Mass
Hormone Research in Paediatrics, 1999A genetic contribution to bone mass determination was first described in the early 70s. Elucidation of gene contribution to this has since been attempted through studies analyzing associations between bone mass acquisition and/or maintenance and polymorphic variations of several genes.

Bone Mass in Primary Coxarthrosis
Acta Orthopaedica Scandinavica, 1979The bone mineral content was measured by gamma absorptiometry at two levels on the forearms, proximally on the shafts and distally close to the wrist, in 53 cases of primary coxarthrosis. The bone mineral content at the distal measuring site, representing trabecular bone, was increased in coxarthrosis cases as compared with normal controls; the ...

Measurements of Bone Mass and Bone Density
Endocrinology and Metabolism Clinics of North America, 1989X-ray-based procedures are available to measure bone mineral density in vitro at almost any skeletal site. These bone density measurements are not useful in the diagnosis of the cause of bone loss but at present are the only tests available for assessing bone mass prior to the occurrence of irreversible changes such as fractures or vertebral ...

Establishment of peak bone mass
Endocrinology and Metabolism Clinics of North America, 2003Among the main areas of progress in osteoporosis research during the last decade or so are the general recognition that this condition, which is the cause of so much pain in the elderly population, has its antecedents in childhood and the identification of the structural basis accounting for much of the differences in bone strength among humans ...

Intraskeletal variability in bone mass
American Journal of Physical Anthropology, 2006AbstractFor methodological or other reasons, a variety of skeletal elements are analyzed and subsequently used as a basis for describing general bone loss and mass. However, bone loss and mass may not be uniform within and among skeletal elements of the same individual because of biomechanical factors.

Abstract The inner and outer diameters of the cortex have been measured in 32 obese subjects in the middle of the second metacarpal bone and in the proximal part of radius. The results, which were compared with an age‐matched control group, showed that the obese subjects had, on an average, an 11% larger cortical area than the controls (p < 0.05 ...

Joint Bone Spine, 2018
A finding of high bone mineral density (BMD) from routine dual-energy X-ray absorptiometry (DXA) screening is not uncommon. No consensus exists about the definition of high BMD, and T-score and/or Z-score cutoffs of ≥+2.5 or ≥+4 have been suggested. The many disorders that can result in high BMD are usually classified based on whether the BMD changes ...

Central regulation of bone mass
Seminars in Cell & Developmental Biology, 2008The traditional view of skeletal homeostasis as a primarily endocrine activity has been expanded in recent years following the identification of direct neural pathways controlling bone homeostasis via central relays. Powerful control over both anabolic and catabolic activities have been isolated to neurons of the hypothalamus, enabling large changes in
