Inclusion criteria

Inclusion criteria: Group A: young, healthy men and women: - Age between 18 and 35 years - Ability to provide consent/informed consent - Absence of diseases (assessed during the screening interview, decision made by the clinical investigator) - BMI 23 kg/m² - Grip strength = 16 kg for women; grip strength = 27 kg for men Group C: potentially sarcopenic seniors: - Age from 70 years - Ability to provide consent/informed consent - BMI = 23 kg/m² - Grip strength < 16 kg for women; grip strength < 27 kg for men

Exclusion criteria

Exclusion criteria: For all groups, the following exclusion criteria apply: - Individuals with comorbidities that affect movement (e.g., orthopedic conditions with significant joint wear, neurological diseases such as stroke and Parkinson's disease; assessed during the screening interview, decision made by the clinical investigator) - Terminal illnesses - Significant edema in the legs or forearms (assessment before study inclusion, decision made by the clinical investigator) - Peripheral arterial occlusive disease (assessed during the screening interview, decision made by the clinical investigator) - Pathological fractures that have occurred currently or in the past - Individuals who can only perform movements of the lower or upper extremities with pain - Amputation/loss of a lower limb - Individuals with implanted active devices such as pacemakers, (internal or external) defibrillators, nerve/muscle stimulation devices (reason: BIA devices are not approved) - Individuals with previous allergic reactions to contact sprays (assessed during the screening interview, decision made by the clinical investigator) - Long-standing wounds with poor healing tendencies located within the area of the electrode array (assessment before study inclusion, decision made by the clinical investigator) - Dysarthria/Aphasia - Insufficient German language skills (study materials are only available in German) - Presbycusis that cannot be compensated by hearing aids - Individuals with severe visual impairment (decision made by the clinical investigator; visual impairment correctable in daily life with glasses is not an exclusion criterion) - Lack of ability to provide consent due to psychiatric disorders (psychoses, dementia) - Individuals weighing over 150 kg (load limit for Multitrainer Pro). - Individuals who are detained due to an official order or a court order. Additionally for Group A: young, healthy women: - Exclusion of pregnancy (assessed during the screening interview) Additionally for Group B: healthy seniors: - More than one chronic condition assessed during the screening interview; decision made by the clinical investigator.

Design outcomes

Primary

MeasureTime frame
The study investigates the physiological relationship between the bioimpedance of resting and loaded muscle tissue in younger individuals, older adults, and geriatric patients. This aims to analyze a potential correlation between immobility and the dielectric properties of the extremities. Findings from this research could form the basis for further studies that explore the electrical properties of musculature in relation to immobility in aging. An increase in mobility among older adults can help reduce potential fall risk and thereby to enhance the quality of life for seniors.
