the ASEP Board of Directors

Last month my whole family packed for the annual ASEP national meeting. Knowing fully that the trip would take 16 hours each way one might ask why, and I wouldnt blame them. It was a lot of driving in just one weekend! The reasons for such zeal stem from the experiences that the meeting always brings. The lectures range from new research findings to highly practical and thought-provoking talks regarding gainful employment in a struggling profession. Im sure that at least some of those in attendance came away considering entirely new career possibilities, from bariatric treatment to lifestyle counseling.

More importantly, perhaps, the people involved are highly sincere. These persons, from the conference organizers to the presenters that fly-in from around the globe, are the kinds of people to which I want to expose my own students. They care about young graduates who face a profession confused by hundreds of legally questionable certifications. They actually want better for those who succeed themselves. They want to build a unified profession with legal recognition through licensure for graduates. They see the ethical dilemma of accepting many thousands in tuition payments while focusing principally on their own research or funding agendas. Sure theres scholarship and professional development among them, but not at the expense of quality advising available even to those who arent on their official departmental advisee lists.

On the long drive home, I found it difficult to understand how any other professional group could fault these teachers and students as being a splinter group or even a heretical bunch that should be discouraged. How could it possibly be that Ive heard no fewer than three tales, in as many weeks, of faculty in fear for their jobs because they embraced ASEPs mission and thus faced political pressure from those who guard the comfortable ACSM status quo. Does it really have to come to this? I still believe that somehow, the major organizations involved with exercise science programs can work together to FINALLY get their graduates the respect they deserve. As a professor in a related field (and there were others at the ASEP National Meeting), I fully recognize the equal and sometimes superior theoretical base that EPs possess.

But quality without anyone knowing about it isnt always helpful, as many exercise science grads bank accounts can attest. This is something ASEP is aggressively remedying. Marketing, legal support through awareness and lobbying, and enhancement of the EP's skill set are badly needed benefits that ASEP is pursuing. And the National Meeting and Conference is a great place to start garnering such benefits.

Sincerity, unity and benefits. Thats why I drove for 32-hours in a single weekend last month.

Q.) I have a question about how one's max and target heart rates are affected by individual physiological variation. I have an unusually low blood pressure. I am making an educated guess that given this fact it means that my heart must have to pump faster/ more times per min to perfuse active tissue properly. If this is the case how do I go about getting and accurate idea of my max heart rate. I am a biologist so please feel free to provide as detailed of an explanation as you feel is appropriate.

Thanks a bunch.

A.) Dear Helynn,

There are several interrelated factors that influence overall cardiovascular function. Taking blood pressure as the factor being regulated, and assuming that all other related factors do not change, an increase in heart rate will increase blood pressure. Similarly, an increase in stroke volume (amount of blood pumped by the heart per beat) will increase blood pressure. An increase in vascular resistance, or resistance of the blood vessels to the flow of blood through them, also will increase blood pressure. Vascular resistance itself is largely controlled by dilation and constriction of the blood vessels. So, a decrease in blood vessel diameter will increase vascular resistance, which in turn will increase blood pressure. A decrease in heart rate, stroke volume, or vascular resistance will decrease blood pressure, again assuming the other factors do not change.

Having discussed all of this, your question specifically addresses how to best determine maximal heart rate. The only way to truly determine this is to measure it during a maximal aerobic effort (i.e., at the end point of a true maximal aerobic capacity test). Potential limitations to this include the possibility that a true maximal effort is not achieved or that some other factor (e.g., skeletal muscle fatigue) is the limiting factor, not the cardiovascular system. Unfortunately, the formula frequently used to predict maximal heart rate (HRmax = 220 age) has a great deal of error; up to ~ 10 beats/min. In fact, Robergs and Landwehr [JEPonline 2002, 5(2): 1-10] indicate that there is no scientific basis for this equation. Given this, any target heart rate information that predicts maximal heart rate as part of the calculations, may have substantial error.

A good indicator of target training intensity is the rating of perceived exertion (RPE) scale. The basis of this scale is that an individuals perception of physical effort fairly accurately indicates the actual level of effort relative to maximal ability. So if a true maximal heart rate cannot be determined, the RPE scale may be a better means to determine an appropriate training intensity.

And keep in mind: For more information on professional scope of practice, professional standards and code of ethics for exercise physiologists, accreditation of academic programs, board certification examination, and other important tasks already completed by ASEP in establishing a profession, visit: www.asep.org
