Current Research

    This page contains a brief overview of some of the most recent research being
conducted in the Exercise Physiology Laboratory.  These projects are a
combination of masters and doctoral work, done in conjunction with the faculty of
the Exercise Physiology Program.

Finley, Cullum, and Yates:  Validation of a portable metabolic measurement system.
    This project is a validation study of one of a  portable metabolic
unit.  The validation of the portable unit is being done through the use of Douglas
Bags and a  Metabolic Cart.  Testing consists of increasing resistance
testing on a cycle ergometer while simultaneously breathing through the portable
system, with small samples being collected in Douglas Bags for gas analysis.

Cullum and Yates:  Evaluation of an Automated Metabolic Cart Compared to Douglas Bag Measurement of VO2.
    The purpose of this project is to validate a metabolic cart using a progressive
cycle ergometer test and collecting expired gases in douglas bags.  The contents of
the bags are  measured by the metabolic cart, with volume being measured by the
cart and being checked by being analyzed by a flow meter.

Whatley and Clasey:  Validity of Bioelectrical Impedance Analyzer (BIA) Measures to Estimate Body Composition in Young Healthy Adults.
   The purpose of this study is to investigate the validity of BIA measurements in
a group of young healthy adults.  The study compares five different analyzers that
range cost and size.  Some of the other components of this study are measurement
of total body water using the D2O method,  and hydrostatic weighing.

Bellew and Yates:  Age-Related Changes in Concentric Versus Eccentric Quadriceps Strength in Older and Younger Females.
   The purpose of this study is to investigate the changes that occur in concentric
and eccentric strength with aging.  This study is being performed on both older and
younger females so changes that do occur can be clearly marked.  Testing is being
performed using an isokinetic dynamometer at varying angular velocities, with each
subject being familiarized with the testing.  The subject population consists of 9
females between the ages of 20-29 and seven females between the ages of 60-69.

Crosby and Yates:  Effects of Albuterol on Delayed Muscle Soreness.
   The purpose of this study is to examine the effects, if any of Albuterol on
muscle strength and soreness.  The study involves giving either Albuterol or a
placebo and inducing muscle soreness through exhaustive arm exercise.  The
testing consists of several sessions designed to measure degree of muscle soreness
and resulting strength loss, and then testing the other arm in the same fashion.
Testing is being performed using an isokinetic dynamometer to elicit muscle
