B |
Basal Metabolic Rate (BMR)
The energy requirements necessary
for maintenance of life processes
such as heart beat, breathing
and cell metabolic activities.
Biomechanics and Ergonomics
Biomechanics is
the mechanical study of living
beings. In the case of fitness
equipment, it is the study of
the exercise machines effect on
the person, and the person's effect
on the machine. Ergonomics
are sometimes called "human factors"
where the overall aim is to ensure
that our knowledge of human characteristics
is brought to bear on practical
problems of people at work and
in leisure. In the case of a treadmill,
it may mean things like ensuring
buttons do what you think they
will, the heart rate sensors are
placed in a thoughtful manner,
and the cupholders are placed
in convenient locations. Life
Fitness has a full-time team of
engineers that focus on these
disciplines in order to ensure
our products are the safest, easiest
to use, and most biomechanically
correct on the market, so the
workouts on your machine provide
maximum benefit, with minimum
risk of injury.

FlexDeck® shock absorption
system
Life Fitness® Treadmills are equipped
with the exclusive, patented FlexDeck
shock absorption system, which
consists of under-the-deck Lifespring
shock made of an advanced, ultraviolet
(UV) cured polyurethane elastomer
material.
The FlexDeck shock absorption
system offers users of varying
weights similar cushioning via
the Lifespring shock absorber’s
variable-rate oval design. This
design allow the deck to flex
downward with the force of the
user’s foot and then gently upward
as the foot is lifted. The FlexDeck
shock absorption system insures
safe, comfortable exercise by
reducing impact to ankles, knees
and hips by nearly 30% more than
ordinary treadmills.
Competitive deck cushioning systems
use rubber or foam to cushion
the running surface of their treadmills.
The spring in the deck initially
feels very good, but over time
the rubber or foam will compress,
break down and offer little of
its initial good feel, while losing
the cushioning effect for the
user.
Unlike rubber or foam, Life Spring
shock absorbers will never break
down or wear out. Life Fitness
is the only manufacturer in the
industry to provide a lifetime
warranty for their treadmill shock
absorbers.
With Life Fitness Treadmills and
our exclusive FlexDeck shock absorption
system, the flex experienced the
first time will be the same flex
experienced in all workouts, year
after year.

LDL (low-density) lipoproteins.
Heart Rate
The number of times the heart
beats in one minute.
Heart Rate Zone Training™
A Heart Rate Zone Training program
does more than just calculate
the user's heart rate, it automatically
and continuously controls resistance
or elevation levels on the equipment
to keep users in their optimal
heart rate training zone, providing
safer, more effective workouts.
It eliminates over and under training
by taking the guesswork out of
exercising, keeping users motivated
and on the right track to achieve
their fitness goals.
|
I |

difficulty as related to a workout.
Interval Training
Deliberately alternating between
brief periods of lower and higher

Isokinetic
Contraction in which the tension
developed by the muscle while
shortening at constant speed is
consistent over the full range
of motion.
Isometric
Contraction against an immovable
force; static; a muscle contraction
in which the tension increases,
but muscle length remains the
same.
Isotonic
Movement against a movable force;
dynamic; a muscle contraction
in which the tension increases
while the muscle length changes
(concentric: muscle shortens;
eccentric: muscle lengthens).
IsoTrack® Stepping System
This superior belt-drive system
powers an easy-on-the-knees independent
stepping motion. Its ergonomically-angled
linear slide mechanism mimics
a real stepping motion and develops
each leg independently for balanced
results. And the IsoTrack system
makes our stairclimbers quieter
and cleaner than chain drive systems,
with virtually no maintenance
to worry about.

L |
Lifepulse™
A state-of-the-art HR monitoring
system that uses the industries
only Digital Signal Processing
(DSP) system. It works through
conveniently placed hand sensors
or via hands-free radio telemetry
using a wireless Polar chest strap.
Heart rate monitoring at rest
is relatively easy to accomplish,
since hand touch sensors or telemetry
straps can pick up and read the
electrical impulses generated
by the heart muscle.
When a person begins exercising,
working muscles create more powerful
electrical impulses than when
at rest. These impulses can be
confused with those of the heart
muscle when monitors try to detect
and distinguish the signals given
off by the working body.
Only Lifepulse uses a patented
digital processing system to filter
out the noise of the working muscles.
It zeros in on the heart muscle
electrical impulses to display
a heart rate reading with accuracy
similar to a clinical EKG. Competitive
hand sensor systems using less
accurate analog technology cannot
match the precision.
Lifespring™ shock absorbers
Lifespring shock absorbers are
made of an advanced, ultraviolet
(UV) cured polyurethane elastomer
material. The same super-strong,
yet flexible, material found in
Corvette suspensions and giant
225 ton mining truck suspensons.
And because the Lifespring material
is nearly indestructible, the
flex experienced during the first
use will be the same flex experienced
in all subsequent workouts, even
years later. Plus, you can customize
the feel of your treadmill deck
by adding or removing Lifespring?
shock absorbers to make your deck
more rigid or flexible.
Link6™ elliptical drive system
Life Fitness® Elliptical Cross-Trainers
incorporate a unique Link 6 elliptical
drive system that provides the
optimal elliptical path for the
most effective and biomechanically
correct movement possible. Extensive
research was done to track the
motion of the ellipse and how
the exerciser moves with the machine
to make constant refinements until
the most effective path was created.

is transmitted from a heart rate
monitor chest strap to a receiver
on a piece of cardiovascular equipment
or in a wristwatch receiver.
Total Body Workout
Total body workouts, like on Life
Fitness total-body elliptical
cross-trainers, involve exercising
all the body's major muscle groups
at once in order to derive a variety
of benefits. These benefits include
increases muscle tone in the upper
and lower body simultaneously,
burning a greater number of calories
in a shorter period of time than
with exercise that works only
the lower body, and a lower perceived
exertion level while exercising
since the work is being distributed
over a greater portion of the
body.
