Abstract

Background: Bone geometry parameters are essential for evaluating bone health and fracture risk in soccer players, whose physical demands affect their bone characteristics. However, studies on adolescent soccer players linking raw bioelectrical data to bone data are lacking, in addition to potential discrepancies in phase angle (PhA) values obtained using single-frequency (SF-BIA) and multifrequency (MF-BIA) bioelectrical impedance devices.

Aims: In this cross-sectional study, we aimed to compare raw bioelectrical impedance data (resistance (R), reactance (Xc), and PhA values) obtained using SF-BIA and MF-BIA devices and test the relationships among PhA and bioelectrical impedance vector analysis (BIVA) with bone mineral density (BMD), and leg hip-femur geometry (HF-G) parameters in adolescent male soccer players.

Methods: Raw bioelectrical impedance data were assessed using the SF-BIA and MF-BIA devices at a frequency of 50 kHz. The HF-G parameters were obtained by dual-energy X-ray absorptiometry. BIVA was used to compare bone data considering BMD and HF-G median values.

Results: Overall, 59 adolescent male soccer players participated in this study. Raw SF-BIA data had lower R values (-19.3 %, p < 0.001), but higher Xc (+5.3 %, p < 0.001) and PhA values (+20.3 %, p < 0.001) than when using MF-BIA data. PhA values obtained using SF-BIA (r = 0.27, p = 0.04) or MF-BIA (r = 0.43, p < 0.001) were positively correlated with total hip-femur BMD. Considering BIVA, the ellipses differed for the total BMD (p = 0.0018), neck BMD (p = 0.026), and cross-sectional area (p = 0.024).

Conclusion: The PhA and R values obtained using SF-BIA were higher than those obtained using MF-BIA, possibly because of the technological differences between the devices. However, the MF-BIA data suggests that PhA and BIVA can be used as tools for continuous use to warn of possible imbalances in bone tissue.

期刊介绍： The Journal is committed to serving ISCD''s mission - the education of heterogenous physician specialties and technologists who are involved in the clinical assessment of skeletal health. The focus of JCD is bone mass measurement, including epidemiology of bone mass, how drugs and diseases alter bone mass, new techniques and quality assurance in bone mass imaging technologies, and bone mass health/economics. Combining high quality research and review articles with sound, practice-oriented advice, JCD meets the diverse diagnostic and management needs of radiologists, endocrinologists, nephrologists, rheumatologists, gynecologists, family physicians, internists, and technologists whose patients require diagnostic clinical densitometry for therapeutic management.
