Validity Of Body Volume Estimates From Infrared 3-Dimensional Scanning And Dual-Energy X-Ray Absorptiometry As Compared To Air Displacement Plethysmography, Marqui Benavides, Michael Moore, Jacob Dellinger, Claire Underwood, Tyler Dierolf, Brian Adamson, Grant M. Tinsley
International Journal of Exercise Science: Conference Proceedings
Traditional methods of estimating body volume (BV) such as hydrostatic weighing and air-displacement plethysmography (ADP) could theoretically be replaced using BV estimates obtained by dual-energy x-ray absorptiometry (DXA) or infrared 3-dimensional (3D) scanning devices. Multiple 3D scanning technologies have recently become popularized, including scanners that acquire data through pattern deformations caused by the projected light over the 3D object (i.e., structured light [SL] scanners) or by calculating depth from the time it takes reflected photons to reach the scanner’s image sensor (i.e. time of flight [ToF] scanners). While these 3D scanning technologies currently predict body composition based primarily on circumference …

Bilateral Lean Mass And Dynamic Balance Asymmetry In Collegiate Athletes, Guadalupe Gabriela Herrera, Vipa Bernhardt
Bilateral Lean Mass And Dynamic Balance Asymmetry In Collegiate Athletes, Guadalupe Gabriela Herrera, Vipa Bernhardt
International Journal of Exercise Science: Conference Proceedings
Laterality, or lateral dominance may lead to asymmetry in muscle mass and strength, which in turn could lead to differences in stability and balance. Muscular asymmetry and dynamic balance asymmetry have been independently linked with increased injury risk. For example, athletes with >4cm anterior reach distance differences (ΔARD) were found to be at significantly higher risk to incur injuries. PURPOSE: However, it is unknown if there is an association between muscle mass asymmetry and dynamic balance. Nor is it known if these factors change throughout the sports’ seasonal periods (i.e., off-, pre-, and post-season). The purpose of this preliminary …

Validity Of Four-Compartment Model Body Fat Using Single- Or Multi-Frequency Bioelectrical Impedance Analysis To Estimate Body Water, M. Lane Moore, Marqui L. Benavides, Jacob R. Dellinger, Brian T. Adamson, Claire P. Underwood, Tyler C. Dierolf, Grant M. Tinsley
International Journal of Exercise Science: Conference Proceedings
Most common body composition assessment techniques make assumptions about the body, including the density and hydration of fat-free mass (FFM). An advantage of the four-compartment (4C) model is the ability to take these FFM characteristics into account when assessing body composition, thus reducing potential error. The total body water (TBW) estimate utilized in 4C models is particularly important due to the large contribution of water to an adult human’s total body mass (~40 - 70%) and FFM (~68 - 81%); however, the impact of utilizing different estimates of TBW within 4C model has not been fully explored. PURPOSE: The …
