Validation study of the seated Biody Xpert ZM 3 bioelectrical impedance analysis (BIA) device compared to DXA (Dual-energy X-ray Absorptiometry) for measuring appendicular skeletal muscle mass (ASMM) in older adults. The study evaluated two predictive equations (Kyle and Sergi) and examined associations between phase angle (PhA) and physical performance. Results demonstrate that the population-specific Sergi equation offers superior accuracy, with higher concordance and lower systematic bias than the Kyle equation, while PhA positively correlates with handgrip strength.

Validation study of the Biody Xpert ZM III compared to DXA (Dual-energy X-ray Absorptiometry), conducted in both sitting and supine positions. Results demonstrate excellent agreement, with a mean deviation of approximately 3.7 Ω on impedance measurements and less than 1% difference on fat mass assessment. No statistically significant differences were observed for fat mass, lean mass, or fat-free mass.

Population-based study proposing a two-step algorithm combining the SARC-F questionnaire, handgrip strength measurement, and targeted BIA (Bioelectrical Impedance Analysis). This approach demonstrates excellent diagnostic performance for identifying sarcopenia and frailty in community-dwelling older adults.

Study evaluating the reproducibility of Spectroscopic Bioimpedance (BIS) parameters for characterizing skeletal muscle properties. Results demonstrate good measurement stability and sensitivity to variations in muscle length and circumference, suggesting the capacity to detect structural and functional alterations.

Study developing a multivariate predictive model combining body composition and lipid profile in young subjects. Bioimpedance-derived parameters significantly improve the accuracy of cardiovascular risk prediction models compared to conventional approaches.

Exploratory study analyzing the association between phase angle, impedance ratio, and markers of meta-inflammation following an intestinal cleansing protocol in overweight women. Results suggest that phase angle may serve as a superior indicator of inflammatory status.

Cross-sectional study conducted in 89 Moroccan adults aged 29 to 66 years, aimed at assessing the prevalence of obesity and its impact on body composition. Measurements obtained via Bioelectrical Impedance Analysis (BIA) confirm the device's ability to provide reliable data under real-world conditions.

Repeated apnea diving episodes may induce modest but cumulative oxidative and inflammatory responses, likely independent of decompression-related mechanisms. These observations suggest that biomonitoring tools could provide valuable insights to support recovery strategies and enhance diver safety.

Single-center interventional study with female handball players, examining the effects of chronic energy deficiency, the Mediterranean diet, and antioxidants on athletic performance. The BiodyXpert ZM II was used to assess body composition, including appendicular skeletal muscle mass, fat-free hydration, and fluid balance. Results indicate that all three nutritional interventions led to improvements in body composition, with no single intervention demonstrating significantly superior effects over the others.
