The study will cover 130 healthy adults. 65 men and 65 women in an age range of 18 to 65 years with a BMI of 18.5 to 35 kg/m2 are planned to be recruited.
- Bioelectrical Impedance of 5 and 50 kHz for one body side [ Time Frame: 15 minutes ]
- Bioelectrical Impedance of 50 kHz for all 4 extremities [ Time Frame: 15 minutes ]
- Bioelectrical Impedance of 1, 1.5, 2, 3, 7.5, 10, 15, 20, 30, 75, 100, 150, 200, 300, 500, 750 and 1,000 kHz [ Time Frame: 15 minutes ]The measurement is planned to be done for all body segments: right arm, left arm, right leg, left leg, trunk, right body side and left body side. In total resistance and reactance at 19 frequencies for 7 body segments are planned to be measured.
- Generation of prediction equations for Sceletal Muscle Mass based on MRI [ Time Frame: 1 hour ]
- Bioelectrical Impedance in sitting, lying and standing [ Time Frame: 15 minutes ]
- Precision Study [ Time Frame: 15 min ]
The precision study pursues three targets:
- Repeatability (variability across successive measurements within a short time period taken by the same operator and the same device; device is repositioned between successive measurements).
- Between-operator precision (variability across measurements taken by the same device, but different operators).
- Between-device precision (variability across measurements taken by the same operator, but different devices).
