BACKGROUND The acute effects of physical activity on intestinal calcium (Ca) uptake and on bone metabolism are not known. AIM OF THE STUDY To investigate the consequences of an acute aerobic exercise bout on fractional Ca absorption and on biomarkers of bone turnover. METHODS With the use of a cross over design, eighteen male athletes, aged 25.2 (SE(More)
The effect of physical activity on human calcium (Ca) metabolism is still not completely understood. Thus, we investigated fractional Ca absorption using a stable strontium test (Fc240), calciotropic hormones, and renal Ca excretion in 31 young men with a high activity level (GH) and in 26 age-matched sedentary control subjects (GL). Weekly hours spent on(More)

Zur Umsetzung neuer Bildaufnahmekonzepte bei der intraoperativen 3D-Röntgenbildgebung wurde ein Konzept mit unabhängig voneinander beweglicher Röntgenquelle und Röntgen-Flachbilddetektor entwickelt. Gerade zur Anwendung neuer Bildaufnahmestrategien ist die freie Bewegung beider Komponenten vorteilhaft. In diesem Zusammenhang wird ein Konzept einer an der(More)
