What is Exercise Physiology？
Raena Morgan（RM)：Doctor Bloomer,you hold a PhD in Exercise Physiology.Could you tell us a little bit about that field？Didn't it used to be called sports medicine,or is it still called sports medicine？
Dr.Richard Bloomer（RB)：Well,exercise physiology really involves,from a research perspective,the study of acute and chronic exercise in relation to a number of physiological parameters.Typically,in a laboratory,people may look at the acute responses and adaptations with exercise in relation to,for example,the cardiorespiratory system,skeletal muscle system,the endocrine system,the metabolic system,et cetera.Typically,when you see reports in the news that exercise was shown to be beneficial for a certain disease,for example,diabetes prevention...
RM：Right.
RB：...and prevention of heart disease or certain forms of cancer,et cetera.Traditionally exercise physiologists are the ones that are doing that sort of work in addition to MD's and PhD's with other degrees and backgrounds.Now sports medicine really is more related to the prevention and the rehabilitation...
RM：Okay.
RB：...of certain injuries.So typically with sports medicine you're going to find individuals with backgrounds in athletic training and physical therapy and orthopedics,orthopedic surgery,et cetera,as opposed to exercise physiologists.Exercise physiology really doesn't work...
RM：So the line of departure is exercise physiology actually deals with the physical components of exercise as medicine,is that what you're saying？
RB：That is correct.So the new statement from the AMA and the American College of Sports Medicine touting exercise as medicine or exercise is medicine.That would suggest that exercise can be used to offset some of the declines that we see in...
RM：Okay.(https://www.daowen.com)
RB：...physiological function over time.And traditionally,exercise physiologists at the PhD level may perform that sort of research,and exercise physiologists at the Master's level may work as a clinical exercise physiologist working with,for example,individuals undergoing cardiac or pulmonary rehabilitation...
RM：Okay.
RB：...or perhaps work in an exercise testing laboratory performing stress tests and perfusion studies and those sort of tests.RM：So that's quite a distinction then.
RB：It really is.It's not sports medicine.And again,sports medicine really is focused on the prevention and the rehabilitation of certain sport related injury.
RM：Or athletic expression,right？
RB：Exactly.
RM：And this is exercise as medicine and rehabilitation.
RB：Right.And it's not simply as medicine or rehabilitation.Often times exercise physiologists will focus on improvements in physical performance,whether in dealing with athletes or other individuals who are non-athletes,but improvements in cardiorespiratory endurance,improvements in muscular performance,muscle strength,muscle size,muscle hypertrophy,et cetera,as well as changes in body composition,lean to fat ratio.So exercise physiologists tend to do that sort of work,often times again with exercise being the focus but also with nutrition and nutrient intake and nutraceuticals and dietary supplements as adjuncts to the exercise.
RM：Well that's pretty comprehensive,isn't it？
RB：It sure is.It's a very,very broad field.Individuals like in any other discipline,for example,in medicine,have to specialize and be focused in one area to really develop and expertise in that area.My area of expertise is really something related to antioxidant protection and free radical production,and that area is known as oxidative stress.
