Welcome to Applied Exercise Lab

Applied Exercise Science Laboratory

The Applied Exercise Science Laboratory (AESL) is directed by Professor Stephen F. Crouse and includes permanent affiliated faculty support from Dr. Steven E. Martin and Dr. John S. Green. It serves a primary role in training graduate and undergraduate students for professions in clinical exercise physiology, sports medicine, sports physiology, cardiopulmonary rehabilitation, and worksite fitness/ health promotion.


The general goal of the research in the laboratory is to generate new knowledge for the enhancement of human health, physical fitness, and quality of life through physical activity and healthy nutrition.  Health-related research aims are targeted toward the study of exercise-mediated effects on lipid metabolism, blood pressure, obesity, and on other accepted cardiovascular disease risk factors. In this context, the AESL researchers seek to understand the role of proper nutrition and exercise in the achievement of optimal health.  The research team also works to quantify the exercise benefits accruing from various exercise modalities, such as aquatic, aerobic, and resistance exercise. These studies include objectives to understand the effects of exercise on muscle protein synthesis.


In addition, ongoing research projects are being conducted to profile elite athletes and study training factors in parallel with nutritional supplements that contribute to optimal athletic performance. The laboratory also serves firefighters, law-enforcement officials, and employees and students of Texas A&M University through the FITLIFE Exercise Program, which is coordinated by Dr. Steven E. Martin. This program provides clients with an economical but sophisticated assessment of cardiovascular disease risk and physical fitness, and with a number of scientifically designed exercise classes to improve physical fitness and health.  Research related to the FITLIFE program includes longitudinal physical fitness and cardiovascular disease risk profiling of firefighters and police officers.


This laboratory occupies approximately 5,000 square feet in the Player Development Center – West Campus at Texas A&M University, College Station, Texas.  Located within this laboratory is over $500,000 worth of state of the art equipment to support human exercise science research and teaching.  The equipment includes:

  • HydroWorx series 1200 aquatic treadmill.
  • General Electric LOGIQ P6 ultrasound system for cardiac, peripheral arterial, and muscle imaging studies
  • Two Medical Graphics Corporation Ultima Cardio2 automated metabolic gas exchange analysis systems with integrated Trackmaster treadmill & Mortara ECG capability.  These MGC Ultima systems also perform computerized spirometry for pulmonary function tests and assessment of resting metabolic rates.
  • Medical Graphics Corporation CCM-Express portable metabolic gas analysis system.
  • Three Quinton Q-Stress systems with integrated treadmills for graded treadmill stress testing with ECG.
  • Lode electronically-braked and three Monark friction braked research grade cycle ergometers.
  • Dual Emission X-ray Absorptiometer (DEXA, General Electric Medical Systems, GE Lunar Prodigy Advance, Madison Wisconsin).
  • Other equipment to analyze body composition including a computerized hydrostatic weighing tank, bio-impedance instrument (The Bodycomp Scale, Valhalla Scientific, San Diego, CA), 5 Lange skinfold calipers, medical-grade height / weight scales.
  • Numerous networked desk-top and notebook computers.
  • The laboratory also houses a BL-2 Level facility for phlebotomy with blood chemistry and plasma volume analysis capability.


Faculty and students working in the Applied Exercise Science Laboratory include:

  • Professor Stephen F. Crouse, FACSM, Applied Exercise Science Laboratory Director
  • Dr. John Green, FACSM, Clinical Professor
  • Dr. Steven Martin, Associate Clinical Professor and FitLife Exercise Program Coordinator
  • Mr. Jason Lytle
  • Undergraduate and graduate interns in applied exercise physiology
