One
way to gauge how hard you are exercising is to use the Borg Scale of
Perceived Exertion. The Borg Scale takes into account your fitness
level: It matches how hard you(feel)you
are working with numbers from 6 to 20; thus, it is a "relative" scale.
The scale starts with "no feeling of exertion," which rates a 6, and
ends with "very, very hard," which rates a 20. Moderate activities
register 11 to 14 on the Borg scale ("fairly light" to "somewhat hard"),
while vigorous activities usually rate a 15 or higher ("hard" to "very,
very hard"). Dr. Gunnar Borg, who created the scale, set it to run from
6 to 20 as a simple way to estimate heart rate—multiplying the Borg
score by 10 gives an approximate heart rate for a particular level of activity.

For
good cardiac health a person would only need to work within the 11-14
band. When it comes to increasing the heart's capacity to work more
efficiently its not necessary to “feel the burn”. In fact putting the
heart under too much strain is not a very wise course of action.
In relation to how we might set up a Heart Healthy Curriculum we might consider the following:
The age and medical condition of the student/students
A
high school athlete is going to need a different program than a fifty
year old truck driver ,suffering from diabetes and living a sedentary
lifestyle. Its very important to access your students. You may ask them
to fill out a membership form containing details of medical history.
This should contain details of any medications they are taking as well
as history of blood pressure, cardiac events and medical procedures such
as surgery. Its best, in my opinion to have your students clear it with
their doctor if they are about to partake in any physical activity. You
may want to see a letter from their doctor giving them the OK to start
your program.
The type of martial arts we teach.
It
may be more difficult(though not impossible) to elevate heart rate
teaching a tai chi class compared to a kick-boxing workout. Some of the
more traditional arts while promoting excellent physical activity
contain little physical exercise. There is a difference. Physical
activity can be anything that involves the movement f the body. A walk
in the park can be physical activity, as can say, mowing the lawn.
Physically exercise on the other hand is a measured activity which can
be monitored and is progressive in nature. To be effective as an aerobic
workout that benefit the heart, our programs need to have a warm up
period of about 10 minutes,a workout period of around 30-35 minutes and a
cool down period of about 10 minutes. After this a 5 minute meditation
period is very useful in relaxing the student. So your workout would
need to last for about 1 hour. How creative can you be in coming up with
a great warm up? Your 30 minute workout section, what will that
contain. Then onto your 1o minute cool down, What have you in your
martial tool box that you can use?
Your knowledge as a teacher
If
you have no knowledge whatsoever of how to elevate heart rate
safely(and many of us in the industry do not) then you need to educate
yourself first before you can hope to educate your students. There are
innumerable websites with some great information. I'll be posting some
at the end of this, so, educate yourself in what it take to put on a
great ,safe, and massively beneficial workout!
But......
it doesn't end there! You will need to encourage your students to
become proactive in their preventative measures in relation to Heart
Defense. You need to understand good diet and how it positively impacts
on Heart Defense. Likewise environmental factors. How about stress ?
Where does that fit in? Lifestyle? Alcohol consumption?
Over
the course of the next few weeks I'll be adding pages that explore
these topics. I'll also add some ideas regarding specific exercises that
I am adding to my syllabus. What might you come up with also?
