The Exercise Physiologist’s Professional PracticeTommy Boone, PhD, MPH, MAM, MBABoard Certified Exercise PhysiologistProfessor, Department of Exercise PhysiologyThe College of St. ScholasticaDuluth, MN 55811UNDERSTANDING CELLULAR and molecular mechanisms of skeletal muscle plasticity may be exciting, but it doesn’t help the college graduate locate a credible job in healthcare. Instead, the capacity to find a good paying job in the public sector relies less on research and more on professionalism. The problem is that talking about muscles adapting to different types of activities is basic to what is presented as exercise physiology. So students learn about power generation and output, and they learn about type 1 fibers being the slowest and type 2B fibers being the fastest [1]. They listen to lectures and take tests on the complex cascade of metabolic steps involved in the development of energy for muscle contraction. Students are taught that physical inactivity, like smoking, high blood pressure, and elevated blood lipids, is an independent risk factor for cardiovascular morbidity and mortality [2]. They are taught that the metabolic syndrome is a function of people not being physically active [3]. If they were active, then, there would be an increased likelihood of preventing and managing type 2 diabetes mellitus [4]. Students are taught that physical activity increases oxygen consumption (VO2) because increased activity of the muscles requires more oxygen to develop ATP for muscle contraction. This thinking is in agreement with the decrease in heart rate (HR) and LDL cholesterol that results from an increase in regular exercise. Students are taught that regularly performed endurance exercise improves the cardiovascular system and muscle metabolism. They understand that regular exercise improves the delivery and extraction of oxygen to the muscles. Their exercise physiology teachers can be heard lecturing on the improved capillary-to-fiber ratio and the in
