Ann Snyder, Ph.D.

The Human Performance Laboratory is equipped to conduct research and deliver undergraduate and graduate education pertaining to cardiovascular, endocrine, metabolic, muscular, and respiratory system responses to exercise and adaptations to exercise training.

Equipment in the Human Performance Laboratory includes:

  • Portable/computerized oxygen uptake system
  • ECG instrumentation
  • Lactate analyzer
  • Near-infrared spectroscopy (NIRS)
  • Ventilation measurement module
  • Woodway treadmill
  • Electronically braked cycle ergometer
  • Computrainer
  • Monarch cycle ergometer
  • Hydrostatic weighing tank
  • Skinfold calipers
  • Various computer software modules

In the Human Performance Laboratory, a number of studies have been performed dealing with the mechanism responsible for amenorrhea (absence of a menstrual period) in athletes. These studies have included the rejection of the hypothesis involving a low percentage of body fat, as well as the examination of a hypothesis involving nutritional inadequacies. Nutritional inadequacies and the blood iron status of athletes have also been studied to determine whether performance and health are compromised by certain diets. Nutritional and physiological profiles of elite athletes are continuously being developed along with training records in an effort to establish a training program for optimal performance that also minimizes the occurrence of overtraining.

Most recently, the lab has examined muscle oxygen saturation through NIRS (near-infrared spectroscopy) to detect a breakpoint in percent oxygen saturation of the muscle during different exercises. We have determined that muscle oxygen saturation can track the changes in training adaptations of triathletes training. To enhance our ability to prescribe exercise training for athletes, muscle oxygen saturation has been examined in relation to oxygen uptake, heart rate, blood lactate levels and ratings of perceived exertion during both cycling and running.

Dr. Snyder brings extensive experience to the lab in working with local and national team speed skaters, triathletes, runners and cyclists to enhance their performance.
