Heart Rate Monitoring
CHAPTER ONE: BASIC OPERATION
This treadmill can monitor your heart rate using either the
chest strap provided with the treadmill or the metal grips on the
hand rails (called contact heart rate or CHR pads). A chest strap
transmits your heart rate to the treadmill via radio, and the CHR
pads connect to a special computer circuit to extract your heart
rate.
Although this treadmill functions fine without using the heart rate
monitoring feature, this kind of monitoring gives you valuable
feedback on your effort level. Chest strap monitoring also allows
you to use Heart Rate Control, the most advanced exercise control
system available.
When you wear a Polar
treadmill will display your heart rate as a digital beats-per-minute
(bpm) readout.

The transmitter strap should be
worn directly against your skin,

Contact Heart Rate
CHAPTER ONE: BASIC OPERATION
Contact
Heart Rate
(CHR)
The contact heart rate (CHR) system lets you monitor your heart
rate without wearing a strap.
Gently grasp the contact heart rate pads as shown.
When the system detects your hands, the Heart Rate label will start
flashing in time with your heart beat. During this time, the system is
analyzing and locking in your heart rate. Within about 15 seconds,
your digital heart rate in beats per minute (bpm) should be displayed.
Important: The CHR System should only be used at speeds of
4 mph or lower. Above this speed the CHR accuracy is unavoidably
unreliable due to large muscle movements.

15
Contact Heart Rate
CHAPTER ONE: BASIC OPERATION
1. Exercise with smooth body motions.
2. Breathe smoothly and regularly, and avoid talking. (Talking
will cause unrepresentative heart rate spikes of 5 to 10 bpm.)
3. Grip the pads lightly, not tightly.
4. Make sure your hands are clean, free of both dirt and hand
lotions.
5. See Appendix A for more details on Contact Heart Rate
monitoring.
When using a Heart Rate Control workout, it is best to use chest
strap monitoring. These workouts work best with the extra
accuracy gained from a chest-contact heart rate monitoring system.

Contact Heart Rate
CHAPTER ONE: BASIC OPERATION
A Note on CHR Accuracy
CHR monitoring may be a bit less accurate than a
chest strap, since the heart rate signals are much
stronger at the chest.
About 5% of the population cannot be picked up
by any CHR system. This is because their heart is
positioned in a more up-and-down manner in their
chest, as opposed to leaning over to one side.

HRC Introduction
CHAPTER TWO: HEART RATE CONTROL WORKOUTS
True’s heart rate control (HRC) workouts let the treadmill monitor
your relative exercise intensity by way of your heart rate, then
automatically adjust the workload to keep you at your target heart
rate and thus your desired exercise intensity.
Your heart rate is a good measure of your body’s exercise stress
level. It reflects differences in your physical condition, how tired
you are, the comfort of the workout environment, even your diet
and emotional state. Using heart rate to control workload takes the
guesswork out of your workout settings.
Consult your physician before using heart rate
controlled workouts for advice on selecting a target
heart rate range. Also, it is important to use the
treadmill for several workouts in the manual mode
while monitoring your heart rate. Compare your
heart rate with how you feel to ensure your safety and comfort.
See Appendix A for a chart that may help you pick a target heart
rate.
HRC
Workout
Introduction
You need to wear a heart rate monitoring chest strap to use heart
rate control. See the “Monitoring Your Heart Rate” section in
Chapter 1 for a guide to proper usage. It is not recommended
that you use the contact heart rate system for heart rate control
workouts.

that your treadmill does not have.
Time-based constant HRC

Cruise Control: while in any workout, set your current heart rate
as your target heart rate by pressing a single key.

Choices During Workout Setup
CHAPTER TWO: HEART RATE CONTROL WORKOUTS
5 - Warm up. At the beginning of an HRC workout, the
treadmill is in full Manual Control mode. Gradually
increase your work level to slowly raise your heart
rate to within 10 beats per minute (bpm) of your
target heart rate.
6 - Heart rate control stage. Now the treadmill takes
control of speed and incline, keeping your heart rate
within a few bpm of your target. If you are using
interval HRC, the treadmill alternates between work
and rest intervals.
7 - Cool-down. At the end of your workout time or
distance, the treadmill reduces workload by half and
goes back into Manual Control mode, where you
directly control your cool-down.
• Your treadmill can remember more than one workout
setup for a heart rate control workout. The ES 5.0 has
five target and two interval HRC setups; and the ES
7.0 and ES 9.0 have 5 target, 5 interval, and 4 distancebased HRC setups. It stores each set of workout
parameters under numbered workouts, for example,
"Target HR 1," "Target HR 2," "Interval HRC 1," etc.
You can select these in later workouts so you don't
have to re-enter your workout parameters, which tend
to stay the same from workout to workout.

Tips and How HRC Works
CHAPTER TWO: HEART RATE CONTROL WORKOUTS
Increase speed and incline gradually to slowly increase your heart
rate to within 10 bpm of your target. For best results, you should
take about five minutes to get to that point.
The treadmill operates in a manual control mode during the warmup stage. You control both speed and incline. You may only increase
speed and incline to the preset maximum values entered.
It is important that you start at a low level of effort and gradually
increase your work load over several minutes until you approach
your target heart rate. This allows your body to adapt to your
workout. Increasing work load gradually will allow you to enter the
heart rate control stage without overshooting your target.
Warming up too fast may cause you to overshoot your target. If this
occurs, it may take several minutes before the computer software
can control your heart rate. You may overshoot and undershoot
your target for several minutes until stable control is achieved.
Tips on the
Warm Up
Stage
How the
HRC System
Controls
your Heart
Rate
To raise your heart rate in HRC mode, speed will always increase
until maximum speed is attained, followed by incline (if incline is
used in the workout).
To lower your heart rate in the HRC mode, incline will always
decrease until zero incline is reached, followed by speed (if incline
is used in the workout).
Speed changes are in 0.1 mph increments. Incline changes are in
0.5% incline increments. This is equal to between 0.10 and 0.15
METs.

Examples of
HRC
Workouts
Cruise
Control
1 - A user who physically cannot walk over 2.5 mph
can safely use heart rate control by entering
maximum speed of 2.5 in an HRC workout.
2 - A runner can run up to a speed of 10 mph, without
hills, by entering a maximum speed of 10 mph and
a maximum incline of 0%.
3 - A walker enters a maximum speed of 4.0 mph and
a maximum incline of 6%. The walker is limited to
a maximum speed of 4.0 mph and incline will be
used if required to elevate the heart rate up to a
maximum of 6%.
This is the simplest way to enter target heart rate training. While
in manual or any program you can enter Target Heart Rate
Control by simply pressing the key. Your current heart rate
will be set as the target.
For best results, you should be at least five minutes into your
workout and warmed up. This will allow Cruise Control to more
accurately control your heart rate.

should be displayed in the Heart Rate window.

More Examples
CHAPTER TWO: HEART RATE CONTROL WORKOUTS
If you enter the HRC stage below 5 mph, the speed you enter will
be the maximum speed of your workout. If you like to walk at a
maximum speed of 3.8 mph, you should enter HRC at 3.8 mph.
If you enter the HRC stage above 5 mph, you will have an additional
1 mph of speed. If you enter HRC at 6 mph, your maximum
attainable speed in the HRC stage will be 7 mph.
If at any time you enter the HRC stage with incline, you will have an
additional 4% of incline available in the HRC stage. If you enter the
HRC stage at 1% incline, your maximum attainable incline will be
5%.
If you do not enter the HRC stage with incline, no incline will be
available during the HRC stage of your workout. Only speed will be
used to control your heart rate.
1 - Enter HRC at 3.5 mph and 4% incline to allow a
maximum speed of 3.5 mph and 8% incline.
2 - Enter HRC at 4.2 mph and 6% incline to allow a

Important Points About HRC
CHAPTER TWO: HEART RATE CONTROL WORKOUTS
Important
Points
About Heart
Rate Control
The heart rate monitor transmitter strap provided with your
treadmill should be worn directly against your skin at about one
inch below the pectoral muscles/breast line. Women should be
careful to place the transmitter below their bra line.
Some moisture is necessary between the strap and your skin. Sweat
from your exercise works best, but ordinary tap water may be used
prior to your workout if desired.
If the transmitter strap is adjusted or moved while exercising,
communication may be temporarily affected.
If communication is lost for 30 seconds, the treadmill will
automatically shut off.
The transmitter strap sends a low-level radio signal to the treadmill,
so interference from other radio and sound waves (including
everything from cordless telephones to loudspeakers) is possible.
The good news is that interference is usually quite brief. If you
continue to have intermittent heart rate display problems, consult
your local service technician, as the transmitter strap batteries may
be low.
Make sure you breath smoothly and regularly.
Talking during your workout usually causes heart rate spikes of five
beats per minute or more, so avoid talking as much as possible.
Maintain a smooth walking or running motion.
A grounded outlet is critical for the HRC system to
function properly. Use a dedicated 110 VAC, grounded
outlet to help prevent interference.

HRC Safety
CHAPTER TWO: HEART RATE CONTROL WORKOUTS
Two users wearing the same kind of transmitter at the same time
and in close proximity may cause false heart rate display readings.
Use only the transmitter provided with your True HRC Treadmill
or a Polar® brand standard transmitter.
True's Heart Rate Control is patented under USPTO #5,462,504.
If your heart rate exceeds your target by 12 beats, there will be a
30% MET reduction in workload to reduce your heart rate.
If your heart rate exceeds your target by 20 beats, the unit will
automatically shut off as a precautionary measure. (Be cautious
when selecting your target heart rate so the 20 beat variance
will not exceed your maximum heart rate as determined by your
physician).

Gerkin Fitness Test
CHAPTER FOUR: GERKIN FITNESS TEST
One way to measure your overall fitness is to take a Gerkin fitness
test. Named after the Arizona researcher who designed this test,
this submaximal treadmill test (submaximal means you work below
maximum effort) is used to predict VO2 max: the volume of oxygen
you can consume while exercising at your maximum capacity. This
particular test has gained great popularity in the firefighter and law
enforcement community. Like most fitness tests, it is classified as
a graded exercise test (GXT). The test is stopped at the point your
heart rate reaches 85% of your age-predicted maximum.
Select the Gerkin test under the Advanced Options key. Enter your
age, which is used to calculate your test termination point.
The Gerkin protocol starts
at 4.5 miles per hour at a
0% incline. It then increases
speed or incline every 60
seconds. For example, at the
seven-minute mark, the speed
increases to 6 miles per hour
while the incline raises to 8%.
When your heart rate reaches
85% of your age-predicted
maximum, the test waits for
your heart rate to exceed the
target for 15 seconds, then
terminates the test.
The version of the Gerkin
Protocol that True Fitness
uses in its exercise machines
is the new equation of
205.8 – 0.685*age. To better
understand why we selected
this method over the outdated
“220 – age” maximal heart
rate equation, you can review

of Exercise Physiology, a PDF

Accuracy of the Gerkin Test
CHAPTER FOUR: GERKIN FITNESS TEST
Accuracy of
the Gerkin
Test
The scientific journal, Occupational Medicine, published a study in
2004 on the accuracy of the Gerkin test. The conclusion:
“The Gerkin treadmill protocol overpredicts VO2max in healthy
men and women and, therefore, should not be used for predicting
VO2max in individual firefighters, particularly if VO2max is a
criterion for inclusion or exclusion from duty. At this time, a valid
treadmill running test is needed for predicting the VO2max value of
individual firefighters.”
However, for the fitness enthusiast who is interested in monitoring
their fitness level, the Gerkin test can be used to measure progress
over time.

What HRC Planner Is
CHAPTER FIVE: HRC PLANNER
HRC Planner creates a 21- to 24-week training program with
a progressive increase in workout intensity and duration. This
program is based on a few simple parameters from you, the user,
including: age, resting heart rate, current activity level, and fitness
goal.
HRC Planner workouts typically range from 15 minutes at the
beginning of a training program to 40 minutes by week 21.
If you are a new user, you will be asked a few personal questions:
age, resting heart rate, current activity level, and fitness goal.
How to measure your resting heart rate: in general, sit very still,
gentle breathing, no distractions, and no talking. Best results come
first thing in the morning, with no food or caffeine intake for at
least three hours. Measure with your fingers against well-known
pulse points like your wrist or your neck, and count for at least 30
seconds, then convert to a beats-per-minute number.
What HRC
Planner Is
HRC Planner
Setup
Current activity level: choose from not active, moderately active
(20 – 60 minutes of moderate to vigorous activity per week), and
very active (more than 60 minutes of moderate to vigorous activity
per week). See workout suggestion section for how this selection
affects your training program as follows:
If you chose “inactive” as your current activity level, the training
program will be a 24-week program recommending three workout
days per week for the first three weeks, four days per week for the
next 13 weeks, and five days per week for the final eight weeks,
followed by a four-day-per-week maintenance program.
If you chose “moderately active” or “very active” as your current
activity level, the training program will be a 21-week program
recommending four days per week for the first 13 weeks, and five
days per week for the final eight weeks, followed by a four-day-perweek maintenance program.

Workout Suggestion
CHAPTER FIVE: HRC PLANNER
Fitness goal: choose from easy improvement, moderate

Creating the Training Program: HRC Planner now creates and
saves your entire training program.
HRC Planner does not keep track of how often you actually work
out. If you train less often than suggested, your training program
will require more total weeks.
Workout
Suggestion
Workout Suggestion: Each time you select HRC Planner after you
have created your training program, HRC Planner suggests your
next workout, recommending a target heart rate and a workout
length.
Adjusting the suggestion:
or you may skip “back” to an easier workout, or even skip “forward”
to a more challenging workout. HRC Planner remembers the last
workout you complete, and resets its internal pointer to that spot.
The next suggested workout is always the workout after the last
workout you completed, as determined by the 24-week training
program.
Workouts Stay the Same for a Week: HRC Planner generates
workouts to be the same for a week, so you will notice workouts are
the same three to five in a row.
Using HRC for each workout: Since all HRC Planner workouts are
heart rate controlled workouts, you set up each workout just like
you do a normal True HRC workout. HRC Planner will suggest
settings for your maximum speed and grade, but you may adjust
these. Like any True HRC workout, HRC Planner remembers your
HRC parameters for your next workout, and you may leave them
the same or readjust them.
You may choose the suggested workout,

The F.I.T. Concept Defined
CHAPTER SEVEN: DESIGNING AN EXERCISE PROGRAM
The workout portion of your exercise program consists of three
major variables: Frequency, Intensity, and Time.
Frequency: How Often You Exercise
You should exercise three to five times a week to improve your
cardiovascular and muscle fitness. Improvements are significantly
smaller with less frequent exercise.
Intensity: How Hard You Exercise
Intensity of exercise is reflected in your heart rate. Exercise must be
sufficiently rigorous to strengthen your heart muscle and condition
your cardiovascular system. Only your doctor can prescribe the
target training heart range appropriate for your particular needs
and physical condition.
Start with exercise that stimulates you to breathe more deeply.
Alternate days of moderate and easy exercise to help your body
adapt to new levels of exertion without unnecessary strain.
What is
the F.I.T.
Concept?
If you are just beginning an exercise program, you may be most
comfortable walking at a speed of 1-2 mph. As you use your
treadmill regularly, higher speeds may be more comfortable and
more effective.
Inability to maintain a smooth, rhythmic motion suggests that your
speed and/or elevation may be too great.
If you feel out of breath before you have exercised 12 minutes, you
are probably exercising too hard.
50
E X C E L S E R I E S O W N E R ’ S G U I D E
More F.I.T. Concept Overview
CHAPTER SEVEN: DESIGNING AN EXERCISE PROGRAM
As your fitness level improves, you will need to increase your
workout intensity in order to reach your target heart rate. The
first increase may be necessary after two to four weeks of regular
exercise. Never exceed your target heart rate zone. Increase the
speed and/or incline on the treadmill to raise your heart rate to the
level recommended by your doctor. The incline feature can be used
to greatly increase the workload without increasing speed.
METs
One MET is the amount of energy your body uses when you're
resting. If a physical activity has an equivalent of 6 METs, its energy
demands are 6 times that of your resting state. The MET is a useful
measurement because it accounts for differences in body weight.
See Appendix C for more details.
Time: How Long You Exercise
Sustained exercise conditions your heart, lungs, and muscles. The
longer you are able to sustain exercise within your target heart
range, the greater the aerobic benefits.
To begin, maintain two to three minutes of steady, rhythmic
exercise and then check your heart rate.
The initial goal for aerobic training is 12 continuous minutes.
Increase your workout time approximately one or two minutes per
week until you are able to maintain 20-30 continuous minutes at
your training heart rate.
E X C E L S E R I E S O W N E R ’ S G U I D E
51
Utilizing the F.I.T. Concept
CHAPTER SEVEN: DESIGNING AN EXERCISE PROGRAM
The F.I.T. concept and chart are designed to help you begin a
program tailored to your needs. You may wish to keep an exercise
log to monitor your progress.
You can get valuable fitness benefits from your True Treadmill.
Using the treadmill regularly may increase the ability of your heart
and lungs to supply oxygen and nutrients to exercising muscles
over an extended period of time. The treadmill will also help you
develop added muscle endurance and balanced strength throughout
your body.
Calculate your maximum heart rate as a first step in developing
your fitness program. The formula to calculate average maximum
heart rate for one minute is 220 beats per minute minus your age.
To find your pulse, locate a vein on your neck or inside your wrist,
then count beats for ten seconds, then multiply by six. (See chart in
Appendix A.)
Using the
F.I.T. Concept
Your Fitness
Program
Determining
Your Needs
It's also important to know your target training zone or target
heart rate. The American Heart Association (AHA) defines target
heart rate as 60-75 percent of your maximum heart rate. This is
high enough to condition, but well within safe limits. The AHA
recommends that you aim for the lower part of the target zone (60
percent) during the first few months of your exercise program. As
you gradually progress you can increase your target to 75 percent.
According to the AHA, "Exercise above 75 percent of the maximum
heart rate may be too strenuous unless you are in excellent physical
condition. Exercise below 60 percent gives your heart and lungs
little conditioning."
52
E X C E L S E R I E S O W N E R ’ S G U I D E
Beginning Your F.I.T. Program
CHAPTER SEVEN: DESIGNING AN EXERCISE PROGRAM
In addition to monitoring your heart rate as you exercise, be certain
of how quickly your heart rate recovers. If your heart rate is over
120 beats per minute five minutes after exercising, or is higher than
normal the morning after exercising, your exertion may be too
strenuous for your current level of fitness. Reducing the intensity of
your workout is recommended.
The age-adjusted target heart rates indicated in the chart in
Appendix A reflect averages. A variety of factors (including
medication, emotional state, temperature, and other conditions) can
affect the exercise heart rate appropriate for you.
Warning: Consult your doctor to establish the exercise
intensity (target heart rate zone) appropriate for your age and
condition before beginning any exercise program.
Warm-Up: Slow and Deliberate Exercise
Beginning
Your Exercise
Program
You are not warmed up until you begin to perspire lightly and
breath more deeply. Warming up prepares your heart and other
muscles for more intense exercise and helps you avoid premature
exhaustion. Begin each workout by walking even if you plan to run.
Start slowly, exploring different speeds until you can comfortably
sustain your speed.
A good suggestion is a minimum of three minutes. Perspiration on
your brow is a good indicator of a thorough warm-up. The older
you are, the longer your warm-up period should be.

Your F.I.T. Program Continued
CHAPTER SEVEN: DESIGNING AN EXERCISE PROGRAM
Workout: Brisk and Rhythmic Exercise
The workout trains and conditions your heart, lungs, and muscles
to operate more efficiently. Increase exercise in response to your
heart rate to train and strengthen your cardiovascular system.
Concentrate on moving your arms and legs smoothly. Walk
naturally and avoid jerking motions that can cause pulled muscles,
sprained joints, and loss of balance.
Cool-Down: Slow and Relaxed Exercise
Cooling down relaxes your muscles and gradually lowers your heart
rate. Slowly reduce your workload until your heart rate is below 60
percent of your maximum heart rate. The cool down should last
at least five minutes, followed by some light stretching to enhance
your flexibility.
Beginning a Fitness Program
If you cannot sustain 12 continuous minutes in your target heart
rate zone, exercise several times a day to get into the habit of
exercising.
Try to reach and maintain 60-65 percent of your maximum heart
rate. Alternate exercise with periods of rest until you can sustain 12
continuous minutes of exercise at 60-65 percent of your maximum
heart rate.
Begin exercising in three to five minute sessions.

If you can sustain 12 but not 20 continuous minutes of
exercise in your target heart rate zone:
Exercise three to five days a week.
Rest at least two days per week.
Try to reach and maintain 60-75 percent of your maximum heart
rate with moderate rhythmic exercise.
Begin with 12 continuous minutes. Increase your time by one to
two minutes per week until you can sustain 20 continuous minutes.
If you can sustain 20 continuous minutes in your target heart rate
zone, begin to increase the length and intensity of your workout:
Exercise four to six days a week or on alternate days.
Try to reach and maintain 70-85 percent of your maximum heart
rate with moderate to somewhat hard exercise.
Exercise for 20-30 minutes.
Consistent aerobic exercise will help you change your body
composition by lowering your percentage of body fat. If weight loss
is a goal, combine an increase in the length of your workouts with
a moderate decrease in caloric intake. For weight control, how long
and how often you exercise is more important than how hard you
exercise.
Exercise four to five times a week.

CHAPTER SEVEN: DESIGNING AN EXERCISE PROGRAM
Try to reach and maintain 60-75 percent of your maximum heart
rate with moderate exercise.
Exercise for 30-45 minutes at 60-65 percent of your target heart
rate.
Here are some tips to achieving your weight management goal:
Consume most of your dietary calories at breakfast and lunch, and
eat a light dinner. Do not eat close to bedtime.
Exercise before meals. Moderate exercise will help suppress your
appetite.
Take exercise breaks throughout the day to help increase
metabolism (calorie expenditure).
When you are training to improve strength and performance:
Exercise four to five days a week. Alternate exercise days and
intervals of hard to very hard exercise with easy to moderate
exercise.
Exercise for 30 minutes or longer.
Warning:
If you have pain or tightness in your chest, an irregular heartbeat,
shortness of breath or if you feel faint or have any discomfort
when you exercise, stop! Consult your physician before continuing.
Remember, every workout should begin with a warm-up and finish
with a cool-down.

Lubrication and Cleaning
CHAPTER EIGHT: CARE AND MAINTENANCE
Your True treadmill is constructed of quality materials and
manufactured to provide many years of faithful service. Simple
routine cleaning and a preventive maintenance program will extend
the life of your treadmill.
To prevent electrical shock, be certain the treadmill is turned off
and unplugged from the electrical outlet before performing any
cleaning or routine maintenance.
For average use of your treadmill, True recommends you lubricate
under the treadbelt once per year. For heavy use, which is more
than 10 hours per week, True recommends lubricating every six
months.
Please contact your dealer to obtain the proper lubricants.
Daily: Perspiration should be wiped from the control console and
treadmill surfaces after your workout.
Weekly: You should wipe down your treadmill once a week with a
water dampened, soft cloth. Be careful not to get excessive moisture
between the edge of the overlay panel and the console, as this might
create an electrical hazard or cause the electronics to fail.
Important: do not clean or wipe under the running belt.
Monthly: Clean dust and dirt that might accumulate under and
behind your treadmill once a month. Small rubber particles from
the soles of walking shoes will accumulate alongside the belt and
also behind the unit.

METs
Explanation
and Formulas
As stated earlier, the MET is a unit of exercise measurement that
takes into account body weight. Since energy expenditure in a
weight-bearing exercise such as running, walking, or stairclimbing
is directly proportional to body weight, the formulas to calculate
METs are a bit simpler than for, say, an exercise bike. For example,
7 mph running is always 11.7 METs, no matter who you are.
A MET is defined as 3.5 ml/min/kg of oxygen usage by the body,
where:
ml is milliliters, the actual measured volume of gaseous oxygen
min is minutes
kg is bodyweight in kilograms
This energy consumption rate corresponds to about 72 calories
per hour for a 150-pound person, which approximates the average
basal metabolic rate of the general population.
The best formulas for treadmill energy expenditure also use oxygen
usage by the body, or VO2. The two formulas are:
walking VO2 = (2.68 * speed) + (0.48 * speed * incline) + 3.5
running VO2 = (5.36 * speed) + (0.24 * speed * incline) + 3.5
To get METs, divide the result by 3.5.
(Noted exercise physiologist David Costill's speed constants for
walking and running are 3.06 and 4.86, respectively.)
E X C E L S E R I E S O W N E R ’ S G U I D E
75
APPENDIX C - CALORIE EXPENDITURE & CALCULATIONS
True treadmills use the calorie expenditure formula as described
in Guidelines for Exercise Testing and Prescription from the
American College of Sports Medicine. This is the most
widely accepted formula for running and walking.
The ACSM guide says that running burns calories
twice as fast as walking, e.g., a 150-pound person
jogging at 5 mph requires 548 calories per hour, while
walking at 5 mph requires 274 per hour. See Appendix
C for more details.
(Other respected researchers such as David Costill think the ACSM
overstates the energy difference between running and walking.
Costill believes running requires 60% more energy than walking,
not 100% as calculated by the ACSM. Using the same example,
Costill's calculations result in 496 cal/hour for running 5 mph, with
313 cal/hour for walking 5 mph.)
One potential source of calorie estimate error is that the treadmill
doesn't know if you are running or walking, so it has to make some
assumptions. It assumes you are walking at 3 mph and slower,
and running at 5 mph and faster. Between those two speeds, the
treadmill combines the walking and running formulas to make its
best guess.
A Note About
Calorie
Expenditure
Calculations
Variations in human exercise efficiency are another potential
source of error, with differences of plus or minus 10% common in
the population
