Bioelectrical Impedance Changes Of The Trunk Are Opposite The Limbs Following Acute Hydration Change, Dale R. Wagner
Kinesiology and Health Science Faculty Publications
This study aimed to evaluate the changes in impedance and estimates of body composition variables obtained from segmental multi-frequency bioelectrical impedance analysis (SMFBIA) following acute hydration change. All participants (N = 11 active adults) had SMFBIA measurements at baseline (euhydration), post-dehydration, and post-hyperhydration in an experimental repeated-measures design. Dehydration and hyperhydration trials were randomized with the opposite treatment given 24 h later. Dehydration was achieved via a heat chamber of 40 °C and 60% relative humidity. Hyperhydration was achieved by drinking lightly-salted water (30 mmol·L-1 NaCl; 1.76 g NaCl·L-1) within 30 min. Post-measurements were taken 30 min …

Interdevice Reliability Of A-Mode Ultrasound To Measure Body Composition, Megan Bigler, Dale R. Wagner, R. Stephan Lowry

A-mode ultrasound is a noninvasive, rapid method for measuring subcutaneous fat thickness and estimating body fat percentage (%BF). Validity and reliability of the BodyMetrix BX2000 A-mode ultrasound has been reported; however, this study aimed to compare results from two machines to determine interdevice reliability. Ultrasound measures were repeated with two BX2000 machines at 10 body sites (chest, biceps, triceps, scapula, lower back, hip, waist, thigh, calf, axilla) on 42 males of varying age and leanness (age: 28.6±11.9 y, BMI: 25.4±4.6 kg/m2). The intraclass correlation coefficients ranged from 0.939 to 0.998 with standard errors of measurement from 0.31 to 0.58 mm …
