"32 Hours on the
Lonnie M. Lowery, MA, MS, Ph.D.,
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.
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

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.
