Evaluation of Body Composition Assessments for a High School Wrestling Weight Certification Program

Book Description
Background: The Oregon Wrestling Weight Monitoring Program establishes the athlete's minimum wrestling weight (MW) for the season. This program specifies the wrestler's maximum weight loss rate and was implemented in order to reduce unhealthy weight-cutting behaviors commonly practiced by wrestlers. Aims: (1) To compare differences in percent body fat (%BF) between 3 body composition assessment methods, (2) To examine agreement between 2 hydration assessment methods, (3) To detect the presence of systematic bias in MW-prediction for 2 methods of body composition assessment, compared to a criterion, (4) To gather information pertaining to weight-cutting methods used and the frequency with which these methods were used. Methods: Participants included 55 male and female high school athletes, 18 of whom were wrestlers. Body composition assessment methods included the BODPOD while measuring thoracic gas volume (BPM) (criterion for MW prediction), BODPOD while estimating this volume (BPE), and leg-to-leg- bioelectric impedance analysis (L-BIA). The BODPOD body composition system is a densitometric method similar to hydrostatic weighing, however air displacement is used rather than water displacement. This technique is also referred to as air displacement plethysmography. The systematic bias of BPE and L-BIA were examined. Urine specific gravity (USG) was assessed, as an indicator of hydration level using the dipstick method and an optical refractomer. Wrestlers completed a survey. Results: The 3 methods reported similar %BF values (16.1±8.3, 15.3±8.4, 15.4±7.8) for all athletes (N=51), the subgroup of wrestlers (N=16), and males (N=20), however there was a difference in %BF between L-BIA and BPE and between L-BIA and BPM for females (N=15). Hydration assessment methods did not agree when using the high school USG cutoff (1.025 g mL-1), and agreed weakly when using the NCAA USG cutoff (1.020 g mL-1). Systematic bias existed in BPE, and limits of agreement were twice as large in L-BIA compared to BPE. Most wrestlers engaged in weight-cutting behaviors. Conclusion: L-BIA is not recommended as a method for predicting MW because individual differences between L-BIA and BPM spanned multiple weight classes. Investigators recommend that program officials consider using optical refractometers and/or consider adopting the NCAA hydration cutoff (USG

ACSM's Body Composition Assessment
Author: American College of Sports Medicine
Publisher: Human Kinetics
ISBN: 1492586765
Category : Science
Languages : en
Pages : 202
Book Description
In partnership with the American College of Sports Medicine (ACSM), pioneer body composition experts Timothy G. Lohman and Laurie A. Milliken, along with a team of highly regarded contributors, have compiled a practical guide to performing body composition assessments. With an easy-to-follow format and straightforward writing, ACSM’s Body Composition Assessment provides readers foundational information and scientific research with applications in the fields of medicine, exercise science, nutrition, growth and development, and geriatrics. ACSM’s Body Composition Assessment delves into the methodology for a number of techniques, including DXA, BIA, ultrasound, underwater weighing, ADP, total body water, multicomponent models, anthropometry (including skinfolds and circumferences), and BMI. The text uncovers the sources of error inherent in each measurement technique, and it identifies populations to whom these techniques can be applied with accuracy. Researchers and clinicians alike will benefit from descriptions of methods for use in both laboratory and field settings, protocols for the standardization of each method, and advantages and limitations for each method. The text thoroughly examines the health implications of body composition by looking at the relationships between chronic disease and total body fat, fat distribution, muscle mass, and bone density. It also facilitates the reader’s ability to assess changes in body composition over time and to understand special considerations in assessing body composition in athletes, children, older adults, the overweight population, and clinical populations. ACSM’s Body Composition Assessment is supplemented with a web resource containing audio-narrated PowerPoint slides to support a deep understanding of the content. The slides walk readers through key points and assessments in each chapter, and select photos and tables from the book are included to facilitate learning and retention. ACSM’s Body Composition Assessment will help alleviate errors in body composition assessment, making it an ideal reference for practicing fitness, health, and medical professionals; nutrition specialists; and exercise physiologists.
