Background: Post-menopausal women generally present reduced serum levels of vitamin D, reduced VDR expression in skeletal muscle cells, and a gradual loss of muscle mass and muscle function. The relationship between serum 25-hydroxyvitamin D [25(OH)D3] levels and muscle strength has been extensively investigated, even though there is no agreement in literature. Therefore, aim of our study was to evaluate the effects of vitamin D on 25(OH)D3 levels, muscle strength, and physica...

Background: Among body composition phenotypes there is no consensus on definition and consequences of sarcopenic obese phenotype. The recommended method to quantify the muscle mass is the dual energy X-ray absorptiometry (DXA), based on measurement of total fat mass and appendicular lean mass. A high BMI may provide a great bone mineral density (BMD) in many individuals, but it does not guarantee optimal bone strength. The aim of our study is to investigate the influence of sa...
