Body composition of female office workers compared with infrared reflection measurement, bioimpedance analysis and calipermetry
There are currently many different anthropometric methods for determining the individual body fat percentage, as well as almost as many variants of bioelectric impedance analysis (BIA) and only a single method of infrared reflection measurement (IR) as easily available methods of field research. The present study aims at a simultaneous comparison between calipermetry, IR and BIA. In particular, the question which measurement method could be used …
Extracellular local field potentials in men and women based on a theoretical model of voltage decrease as a function of distance
Extracellular microelectrodes determine the field potential difference adjacent to the neuron and depend on the composition of the tissue, including ohmic resistance and distance from the source. Based on theoretical aspects, a reciprocal voltage versus distance model is postulated, which was assessed by means of clinical neurographical data in men and women. Data of women showed higher voltages and could be slightly better fitted to the model. V…
Follow-up study about hydration parameters at moderate altitude
During residence in high mountain regions, the human water hydration status changes and, from the height of ~ 3,000 m above sea level, is associated with the risk of mountain sickness. The present investigation assessed this phenomenon at moderate height (1,300-2,300 m above sea level) after a residence time of approximately one week by means of bioelectric impedance analysis (BIA). 132 volunteers, attendees of a sports medicine congress (78 men,…

Change of hydration parameters in moderate altitude
During residence in high mountain regions, the human water hydration status changes and, from the height of approximately 3000 m above sea level, is associated with the risk of mountain sickness. The present investigation should assess this phenomenon in moderate height (1300-2300 m above sea level) after a residence time of approximately one week by means of bioelectric impedance analysis (BIA). 50 volunteers, attendees of a sports medicine cong…
Effect of diurnal variation on body composition under consideration of selected chronobiological marker systems
Diurnal variation in body composition in relation to chronobiological parameters was analyzed in 27 healthy students (22-29 years) four times over one day from 5:35 to 0:15 h. Body composition was determined by multifrequency bioimpedance analysis at fixed frequencies (1, 5, 50, 100 kHz). Resistance (R) and reactance (Xc) were measured. Total, extra and intracellular body water (TBW, ECW, ICW), lean body mass (LBM), and fat mass (FM) were derived…
