Comparison of measured and predicted residual lung volume in determining body composition of collegiate wrestlers.

This investigation compared percent fat obtained via underwater weighing using measured and predicted residual lung volume (RLV) in euhydrated and hypohydrated collegiate wrestlers (N = 67). RLV was measured using O(2) rebreathing or O(2) dilution and predicted using 3 equations-Equation 1: (0.019 x height [cm]) + (0.

A new handheld device for measuring resting metabolic rate and oxygen consumption.

Objective: The purpose of this study was to test a new handheld device, the BodyGem (HealtheTech Inc., Golden, CO), that measures resting metabolic rate (RMR).

Subjects/design: Sixty-three adults (43 women, 20 men) (mean+/-SD, age 41.

Evaluation of air displacement for assessing body composition of collegiate wrestlers.

Purpose: To evaluate the accuracy of air displacement plethysmography (ADP) by using the BOD POD in comparison with hydrostatic weighing (HW) in a collegiate wrestling population in hydrated and acutely dehydrated states.

Methods: Body composition was determined by ADP, HW, and three-site skinfolds (SK) in 66 NCAA Division I collegiate wrestlers before and after acute dehydration (2.6% reduction in body mass).

Physiological profile of an elite freestyle wrestler preparing for competition: a case study.

The purpose of the present investigation was to describe the physiological changes of a nationally ranked older elite freestyle wrestler during a 7-month observation period as he prepared for the 2000 Olympic freestyle wrestling trials. A 33-year-old male wrestler was evaluated 3 times during the study for measurements of body composition, resting energy expenditure, maximal oxygen consumption, isometric strength, anaerobic power and capacity, nutritional intake, and various serum plasma constituents. Body weight decreased by 1 kg, which consisted of fat-free mass (FFM), whereas body fat remained stable at 5.
