The
Technology Behind Elliptical
Cross Trainers Creates Unique Advantages and Benefits
by C.J. Gustafson
The word elliptical means
shaped like an oval. In the world of fitness and exercise,
elliptical
technology is a relatively new, innovative equipment design that draws
on a smooth, elliptical movement to provide a low impact form of weight
bearing exercise that is fun and easy to learn.
Elliptical cross trainers
have footpads that allow you to stand up while you exercise.
They
have handgrips for you to hold onto and help maintain
balance. Some
even have handles to use in working your upper body. Because
you
are standing, the exercise is similar to walking or running.
But
the arm bars and elliptical motion create similarities with biking or
skiing.
The main difference with elliptical exercise machines is that although
you are standing and bearing weight, which is important to building
bone
density, your feet never leave the footpads. So unlike
treadmills
or jogging, there is little impact on your joints and
muscles. This
provides a low impact, total body workout.
Elliptical Technology
The advantages of this type
of smooth, non-jarring motion come from the elliptical design of the
exercise
equipment. Elliptical technology has come to be known as a
combination
of mechanisms and design features, unique to elliptical cross trainers,
which create a motion similar to the natural path the feet, legs and
hips
follow during actual motor activities such as walking or running.
There are several different
types of elliptical equipment available, and the list of choices seems
to grow each day. However, most elliptical fitness machines
have
a crank arm that is attached to a stable bar at one end and an axis at
the other. The axis end revolves as the bar moves and the
other end
moves in a flat, nearly liniar back and forth motion. This
causes
an elliptical path for the overall movement of the machine.
Most
elliptical exercise machines built for home use provide resistance
through
a band around the flywheel. Some high end and commercial
elliptical
cross trainers use magnetic resistance.
Like a bicycle, this elliptical
motion is smooth and continuous. With a stair stepper or
other similar
equipment, there is a pattern of motion and reverse motion, an up and
down
or back and forth, to which your feet and legs must continually
adapt.
At the point where the forward motion ends and the reverse motion
begins,
there is an impact from the force of the machine, which is still in
motion.
Your joints, bones, and muscles have to stop the motion and reverse it
each time.
With an elliptical trainer,
there is no halting of motion and reversal of direction. Your
legs
keep moving in the same manner continually, even though there is an
overall
range of motion. Many elliptical cross trainers allow you to
reverse
the direction of motion by changing a setting. Thus you are
able
to work the opposing muscles, while still maintaining the smooth,
non-jarring
motion.
Benefits and Advantages
Studies have shown that weight
bearing exercises are essential for maintaining and improving bone
density.
Yet many weight bearing workouts create high impact stress on joints
and
muscles. This can cause health problems, especially for
people with
injuries or arthritis. Additionally, many of the different
types
of exercise equipment available only work one or two areas of the body,
which is a drawback for people who want an overall workout.
Under most circumstances,
the ideal piece of fitness equipment will be provide weight bearing
exercise,
while limiting impact and providing for a total body workout.
Optimizing
cardiovascular benefits is also important. Many styles of
exercise
equipment address one or two of these concerns, but few combine all the
advantages in an overall fitness package such as that provided by
elliptical
cross trainers.
For example, a stationary
bike provides relatively smooth, non-jarring motion, but since you are
sitting, you don’t get the weight bearing
advantages. A treadmill
fulfills the weight bearing aspect, but at the expense of stress to
your
joints each time your foot hits the running surface. Swimming
is
a great form of exercise that tends to work a majority of the
body’s muscle
groups, however, it is not considered a weight bearing
activity.
When considering the overall needs of an exercise program, few types of
fitness equipment meet the overall needs quite as well as elliptical
cross
trainers.
The advantages and benefits
of an elliptical trainer as compared to other fitness equipment are:
Weight
bearing form of exercise
that helps maintain bone density
Continuous
elliptical motion
creates a low impact workout
The
motion is similar to
walking and is thus easy to learn and sustain
Handles
encourage users
to work upper body muscles providing a total body workout
Offers
one of the best forms
of cardiovascular training – onboard computers help plan and
monitor cardio
workouts.
Equipment
is relatively
simple, so there are fewer parts to replace or mechanical things that
can
go wrong.
Beware Of Imitators
Unfortunately, as with many
innovative, beneficial, and popular ideas, elliptical technology has
become
somewhat corrupted by those who want to cash in on the appeal but who
lack
a commitment to or understanding of the true basis for the
design.
Some elliptical equipment does not offer the natural, simulated
movement
of true elliptical cross trainers. Others use inferior
designs and
materials, resulting in a jerky or jarring motion that negates the
value
of the equipment.
When purchasing an elliptical
exercise machine, be sure that it provides a stable frame or platform,
adequately sized foot platforms, and most importantly, a smooth,
continuous
motion. Try out the machine. Does the movement
required feel
natural and comfortable? Also check to see if the machine has
adjustments
for speed, incline and direction.
Elliptical technology, in
its true form, is one of the best innovations to hit the fitness
industry
in the past decade. It truly does address some of the common
exercise
and health concerns while providing for a relatively easy, often
enjoyable
form of exercise. Unlike some of the gadgets and gimmicks
that have
come along over the years, elliptical cross trainers have the ability
to
help users get fit, lose weight, and improve overall health.
