Exercise Physiology and Nutrition

An Exercise Physiologist is available on site to provide investigators with the following services: Measuring and analyzing bone density and body composition via a DEXA scanner that includes Total Body, Spine (AP and Lateral) Hip and Forearm scans in adults as well as pediatric volunteers; measuring total body water and body composition using Mulitfrequency Bio-electrical Impedance (BIS); measuring body composition via air displacement using a Bod Pod; measuring basal and resting metabolic rates using a metabolic cart; performing V02 sub maximal and maximal effort tests on an exercise bike and treadmill; calculating follow-up exercise protocols based on exercise tests; monitoring heart rate and blood pressure at rest and during exercise; administering physical activity recall questionnaires; monitoring physical activity and energy expenditure using accelerometers and pedometers; measuring various circumference sites; performing manual muscle testing; hand held dynometry; and spirometry testing to determine lung capacity; administering quality of life questionnaires; providing exercise guidance and analyzing and managing all data collected.

The following equipment is availible to investigators

  • DEXA:Dual energy X-ray absorptiometry (DEXA) is used for assessment of bone density in the spine, hip and forearm as well as body composition (body fat and lean mass) using the most recent NHANES reference data.
  • BOD POD:The BOD POD uses a measurement of air displacement to determine body density and body fat. It can be used with individuals weighing up to 400 pounds.
  • Metabolic Cart:The ParvoMedics metabolic cart measures energy expenditure at rest and during exercise as well as measuring the thermic effect of food on metabolism during a controlled diet.
  • Bio-electrical Impedance: A noninvasive method used for determining total body water, as well as changes in body composition specifically, fat free mass, fat mass and total body fat.
  • 12 Lead EKG Stress System:The Quinton Q-Stress System directly interfaces with the Quinton TM55 treadmill for research requiring cardiac exercise testing.
  • Activity and heart rate monitors:Polar 810i heart rate monitors and Actigraph GT1M accelerometers are used to measure heart rate, activity, and energy expenditure in the lab or in the field.

A Research Dietitian is available to provide investigators the following services: nutritional status assessments; food record processing and analysis; nutritional education/counseling to optimize health status and research protocol adherence; metabolic and calorie-controlled meal planning and preparation; and protocol planning/consultations.
