Bone Loss and Physical Activity - A Bio Anthropological Perspective

Sylvia Kirchengast*

Increased life expectancy on the one hand and dramatically reduced physical activity in daily life on the other hand are characteristic features of postmodern life. Consequently Homo sapiens is increasingly confronted with the problems associated with accelerated bone loss, osteoporosis and osteoporosis related fractures. This is true of Industrialised countries as well as of threshold countries. A major risk factor of osteoporosis and low bone mass is physical inactivity. Up to now, bone loss and osteoporosis are mainly focused on from a clinical viewpoint. In the present review a bioanthropological perspective of the association between physical inactivity and osteoporosis is provided. The problem is discussed from the viewpoint of life history theory, but also from the viewpoint of evolutionary biology, especially evolutionary medicine and paleopathology.
