body composition, bone mineral content, measurement validity

Besides the soft tissue analysis in body composition measurement, a hard tissue – bone mass analysis is also performed. The bone parameter values can be used for the assessment of the effect of exercise on the individual’s supporting system and in osteoporosis diagnostics. Bone mass is usually analyzed by the DXA method. However, BIA analyzers are also used, resulting in bone mineral content values (BMC), even though the BIA method is not primarily designed for such analyses. Thus a question arises: how precise are the BIA-measured BMC values and can we use them in a diagnostic practice? The objective of the study was to check the validity of BIA-measured BMC values.
