International Journal of Exercise Science: Conference Proceedings

Within the college population, high blood pressure (BP), as well as obesity and sedentary lifestyles, are seen. Bodyfat influences these outcomes. Much of the literature ignores the possible effects that fitness may have on these outcomes, specifically in females. Purpose: The intent of this study was to determine if VO_MAX can predict arterial stiffness after adjusting for body fat% in college females. Methods: Healthy young females were recruited from Grand Canyon University. Subjects came to the lab for a single visit for the following assessments: height, weight, waist circumference, hip circumference, aortic BP, augmentation pressure (AP), augmentation index adjusted …

Body composition techniques such as skinfold measurements, air displacement plethysmography, and underwater weighing are commonly performed in athletic populations, particularly in youth athletes who may not have access to other laboratory methods. However, little is known whether such body composition estimates can be directly compared across techniques. PURPOSE: To determine the agreement between common two-component (2C) body composition techniques. METHODS: 90 youth athletes (Males: 39; Females: 51; Age: 18.2 ± 2.4 years; Height: 172.0 ± 9.9 cm; Body Mass: 69.0 ± 12.5 kg; Underwater Weighing [UWW] Body Fat Percentage [%BF]: 20.2 ± 7.0%) participated in this study. 2C …

Comparison Of Laboratory-Grade And Consumer-Grade Hand-To-Foot Bioelectrical Impedance Analyzers For Body Composition Estimation, Gabrielle C. Dehaven, Madelin R. Siedler, Christian Rodriguez, Sarah White, Abegale D. Williams, Patrick S. Harty, Matthew T. Stratton, Dale Keith, Jacob Green, Jake Boykin, Grant M. Tinsley

Bioelectrical impedance analysis (BIA) is a simple and effective technique to estimate body composition, including body fat percentage (BFP). While these analyzers are a popular method of describing a person’s body composition, laboratory-grade devices are expensive and inaccessible to most people. As a result, they may be an unrealistic method for consumers to use. However, consumer-grade devices are increasingly available. PURPOSE: The purpose of this study was to compare laboratory-grade and consumer-grade bioelectrical impedance analyzers. METHODS: Seventy-five adults (40 F, 35 M) were evaluated using a laboratory-grade, hand-to-foot, multifrequency bioelectrical impedance analyzer (BIA_LAB; Seca mBCA 515) …

A Comparison Of Multiple Body Composition Measurement Methods To The Department Of Defense’S Physical Fitness And Body Fat Program Procedures, Desmond J. Millender, Holly M. Hall, Jeremy B. Ducharme, Avadney F. Gerard-Osbourne, Ann L. Gibson

International Journal of Exercise Science: Conference Proceedings

INTRODUCTION: The Department of Defense (DoD) developed body composition standards that require service personnel to meet sex- and branch-specific body mass index criteria. Failing to meet these criteria leads to body fat percentage (%BF) estimation via the DoD’s circumference method. Service members exceeding these standards face administrative action and a possible premature discharge, thus emphasizing the importance of accurately estimating %BF with this method.

PURPOSE: To compare the predictive accuracy of the DoD’s circumference-based equation to estimate %BF compared to hydrostatic weighting (HW); segmental and whole-body bioelectrical impedance analyses (BIA), and sex-specific skinfold thickness assessments.

METHODS: Physically active …

Cross-Sectional And Longitudinal Relationships Between Skinfold Thicknesses Obtained By Ultrasonography And Body Fat Estimates Produced By Dual-Energy X-Ray Absorptiometry, Jacob J. Green, Robert W. Smith, Patrick S. Harty, Matthew T. Stratton, Christian Rodriguez, Sarah White, Abegale D. Williams, Baylor A. Johnson, Jacob Dellinger, Marqui Benavides, Madelin R. Siedler, Grant M. Tinsley

International Journal of Exercise Science: Conference Proceedings

Ultrasonography (US) and dual-energy X-ray absorptiometry (DXA) are frequently used to assess body composition. Although sometimes compared cross-sectionally, their agreement longitudinally requires further exploration. Purpose: The purpose of the present study was to examine the cross-sectional and longitudinal relationships between total and segmental raw skinfold thicknesses obtained by US and total and segmental body composition estimates produced by DXA over the course of an overfeeding study. Methods: Twenty healthy, resistance-trained males (mean ± SD; age: 22.0 ± 2.6 years; height: 179.1 ± 7.0 cm; body mass: 74.8 ± 11.5 kg, body fat: 17.5 ± 4.5%) completed a 6-week intervention that …

Offseason Body Composition Changes Detected By Dual-Energy X-Ray Absorptiometry Versus Multifrequency Bioelectrical Impedance Analysis In Collegiate American Football Athletes, Jake R. Boykin, Grant M. Tinsley, Christine M. Harrison, Jessica Prather, Javier Zaragoza, Matthias Tinnin, Shay Smith, Camden Wilson, Lem Taylor

International Journal of Exercise Science: Conference Proceedings

In American football, offseason training is designed to promote increases in muscle strength and size in athletes. Tracking changes in body composition may confer key information about the effectiveness of training programs to football practitioners. PURPOSE: The present study assessed the relationship between body composition changes estimated by dual-energy x-ray absorptiometry (DXA) and bioelectrical impedance analysis (BIA) in football players during the initial period of an offseason training program. METHODS: Body composition in 29 NCAA Division III American football players (mean ± SD; age: 19.7 ± 1.5 y; height: 179.8 ± 6.6 cm; body mass [BM]: 96.1 ± …
