TABLE OF CONTENTS
1. INTRODUCTION
Designed for versatility and durability, the Biodex BioStep and BioStep Clinical Pro meet the
demands of orthopedic, cardiopulmonary, sports medicine, wellness and general conditioning
programs. Featuring a work range of 10 to 600 WATTs, plus self-powered, self-charging capability, the BioStep accommodates a wide variety of people and can be used virtually anywhere.
Software-driven for accurate reporting of real-time data, the BioStep features Constant
Resistance Control while the BioStep Clinical Pro features both Isokinetic Speed Control and
Constant Resistance Control. Because the internal battery is automatically recharged when work
rates reach or exceed 30 WATTs and 50 RPM, both BioStep models can be used in the gym or at
the clinic – without cumbersome power cords. An AC adapter is provided for use at work rates
below 30 WATTs and 50 RPMs. Large wheels make the units easy to move.
Ergonomically designed and simple to operate, both BioSteps feature a step-through design for
easy access. The contoured seat with lumbar support and an indexed track allows extensive
front-to-back adjustment to ensure comfort, safety and biomechanically correct positioning. Both
BioStep models accommodate users from 4'4" to 6'6" and weighing up to 500 pounds.
The easy-to-read, programmable LED display provides immediate user biofeedback for
increased motivation and compliance. It maintains all settings and LED displays for 60 seconds
after the workout is finished. Users can choose from quick-start operation that gets first-timers
right into their exercise routine, or from five pre-programmed exercise profiles for each mode of
operation. All profiles can be modified with the panel controls to provide a multitude of exercise
programs to suit any individual’s need. Heart Rate monitoring is provided through contact
handgrips and Polar telemetry.
The Biodex BioSteps are available in two configurations: Standard and Clinical Pro. A
stabilization kit including foot straps, a trunk stabilization belt, flip-up/flip-down seat arm rests,
and EZ-Grip Handgrips for the adjustable arms is available for both models.
NOTE: Throughout this manual the name BioStep is used to denote both the BioStep and BioStep
Clinical Pro. For functions that differ between the two models, the specific model name is used.
NOTE: In a study designed to examine the test-retest reliability and concurrent criterion validity of VO2
max on the BioStep in community-dwelling older adults, results provided preliminary evidence of reliable
and valid estimates of oxygen consumption by the BioStep when compared with the criterion standard of
direct VO2max measurement in the sample.

PARTS AND ADJUSTMENTS
4. QUICK-START OPERATION
The Biodex BioStep is easy to adjust for user comfort. The seat can be moved forward or back
and the arms adjust, too. The following section explains how to adjust your BioStep for optimum user comfort and positioning.
Seat Front-to-Back Adjustment: The seat can be moved forward or back over a range of 15" to
match user comfort requirements. Proper seat front-to-back positioning will allow the user to
exercise comfortably. Proper seat positioning allows the leg to extend just short of full extension,
provided the patient has no range of motion limitations. In others words, the user should not
lock the knee.
To adjust the seat front-to-back position:
• Pull up on the Seat Front-to-Back Release Handle. While holding the handle up, slide the seat
either forward or back to the desired position. To lock the seat in position, release the handle
and make sure it engages in the appropriate hole. To ensure reproducible positioning, note the
seat position as per the Seat Front-to-Back Position Scale, located on the seat slide track.
Rotating Seat: To aid the user in getting on and off the BioStep, the rotational seat can be turned
left or right.
To rotate the seat:
• Lift on the Seat Rotation Handle, located under the rear of the seat, to release the seat. You
may now swivel the seat left or right until it engages in either position.
• With the seat locked in the desired position, instruct the user to sit down. Pull up on the Seat
Rotation Handle and rotate the seat until it engages in the forward locked position.
Adjustable Arms: Make this a total body cross-trainer.
To adjust the arm handles:
• Loosen the arm handle locking knobs, slide the arms out to the desired length, then tighten
the arm handle locking knobs to secure.
Leveling Guides: Located underneath the front hood of the unit, the leveling guides can be
used to adjust the BioStep to sit level on the floor - even if the floor is slightly uneven. To adjust,
use a 9/16" open-end wrench to raise or lower each guide as appropriate. The BioStep must be
level and stable before being used.
Battery Recharge Jack/AC Adapter (Refer to Figure 1, Insert): The Battery Recharge Jack/AC
Adapter is used to recharge the BioStep and BioStep Clinical Pro batteries, or for use at work
rates below 30 WATTs and 50 RPMs.
NOTE: It is recommended that you plug in the adapter overnight to keep the BioStep battery charged to
full capacity.
The Battery Recharge Jack/AC Adapter must be installed correctly before using, as follows. The
AC adapter is supplied.
1.
2.
Plug the AC adapter cord into the BioStep Battery Recharge Jack/AC Adapter, located at the
rear base of the BioStep. Slip the cord under the cord holder directly to the right of the jack.
Plug the AC adapter into a wall socket to charge the BioStep battery or to use the BioStep at
work rates below 30 WATTs and 50 RPMs.

4. QUICK-START OPERATION
Although the BioStep offers advanced programming capability, it also features a “Quick-Start”
function that allows the user to immediately begin exercise with factory preset default values
serving for the programmable system parameters.
Quick-Start operation is simple. Seat the user, adjust the seat forward and back position and foot
pedal straps as necessary, and proceed as described below:
1. Press <Power On> to power-up. After a brief self-test (which includes display of the current
software version,) the system beeps to signify that it is ready to begin collecting data.
2. Grasp the BioStep adjustable arms and begin to exercise.
3. Use the <+> and <-> adjust effort level buttons to adjust resistance level.
NOTE: The Effort Levels are not wattage settings. They are a series of torque settings with
no given value.
4. To stop the system at any time, simply stop exercising. All parameters will continue to display
for one minute before the system shuts off. If you want to turn the system off and automatically reset the display, press <Power ON > again.
NOTE: The BioStep provides Constant Resistance Control exercise mode. The BioStep Clinical Pro also
offers Constant Resistance Control exercise mode, but defaults to Isokinetic Mode. A green LED on the
display activates to show the selected mode on the Clinical Pro. To change modes, on the BioStep Clinical
Pro, press <Select Exercise> (#4 on display).
NOTE: To provide heart rate monitoring, the subject must hold onto both heart rate contact handgrips or
use the telemetry chest strap.
NOTE: For the first 24 hours of operation, the BioStep should be used with the AC Adapter.

BASIC OPERATION
6. DISPLAY PARAMETERS
The top window of the display panel offers readouts for common parameters of exercise and
training interest. For the Biostep, these parameters include Time, WATTs, Calories, METs and
Heart Rate with work rate shown in RPMs. For the BioStep Clinical Pro, display parameters
include Time, RPM, WATTs, Calories, METs and Heart Rate with work rate shown in WATTs. As
you exercise, the system displays values for each parameter in the display window. A green
indicator light denotes the parameter currently being displayed.
A low-battery LED is located at the bottom left of the display. This indicator illuminates if the
battery needs to be recharged. To recharge the battery, simply plug the input jack of the recharging pack into the receptacle at the front of the cycle base or exercise at higher work rates and
speeds above 50 RPM. Plug the opposite end of the recharging pack into a wall socket. The system will recharge even while turned OFF.
NOTE: The BioStep has a Time-Out function based on the system clock. If left on without being used for
more than 60 seconds, the BioStep automatically turns OFF and all data is lost. For this reason, it is
important to check all accumulated data immediately following any exercise session.
NOTE: An explanation of METs, and the relationship of calories burned to oxygen consumption and
METs, is provided in Chapter 10, Additional Considerations.
NOTE: To toggle OFF the “beep” that sounds as parameters scroll during exercise:
1. While pressing <Power ON/OFF> to power up the BioStep, press and hold down the <M> and
<Select Display> button until “bPr” appears in the top window. (Do not pedal at this point.)
2. Press <–Adjust> twice so that OFF appears in the top window.
3. Press <Select Display> twice so that 150 appears in the top window (you should hear a beep).
4. Press <Power ON/OFF> to turn the power OFF.
5. Press <Power ON/OFF to turn the power back ON. The beep should now be disabled
during exercise mode.
DISPLAY PARAMETERS
— 12 —
7. SELECTING THE RESISTANCE MODE
(Clinical Pro Only)
The BioStep Clinical Pro provides two modes of operation: Constant Resistance Control and
Isokinetic Speed Control. Either mode is selected using the <Select Exercise> key. The BioStep
Clinical Pro defaults to Constant Resistance Control. Pressing the <Select Exercise> key will let
you toggle between the two choices. A LED illuminates next to the current selection. The
Constant Resistance Level or Isokinetic Speed selected are displayed in the exercise window at
the bottom of the display. Resistance level and WATTs are also displayed in the resistance level
display bar.
NOTE: Although the resistance level display bar shows up to 300 WATTs, the LED display will show up
to 600 WATTs.
NOTE: Work rates of 30 to 600 WATTs can be achieved without using the AC adapter when above 30
WATTs and 50 RPM. Using the AC adapter will allow users to achieve work rates as low as 50 WATTs at
25 RPM.
CONSTANT RESISTANCE CONTROL (AEROBIC EXERCISE)
• Excellent for heart rate and pulmonary rehab
• Popular for general aerobic conditioning
Constant Resistance Control is ideal for cardiovascular and general aerobic exercise. In this
mode, subjects can pedal as fast or as slow as they wish. Using Constant Resistance Control, no
matter how fast or slow the subject exercises the resistance stays the same.
When Constant Resistance Control is selected, resistance level is displayed in the Resistance
Level Display Window and Resistance Level Display Bar. A selection of 30 resistance levels provides a wide range of work-rate choices. Weak, de-conditioned, or post-operative patients, for
example, can exercise at work rates as low as 10 WATTs. Stronger subjects ranging up to highly
conditioned athletes can demand as much as 600 WATTs.
ISOKINETIC SPEED CONTROL (STRENGTH EXERCISE)
• Speed is always constant and resistance is accommodating
• Pedal hard, work rate increases. Pedal easy, work rate decreases
• Excellent for strengthening and building endurance
• Popular for sport training and physical rehabilitation
Isokinetic Speed Control provides accommodating resistance throughout the subject’s entire
stepping range of motion for the duration of the exercise period. Resistance continuously matches resistance, accommodating to variations in the subject’s force output due to weakness or pain
at specific points in the range of motion, and to fatigue over the course of the cycling period.
With a selection of speeds ranging from 50 to 120 deg/sec, Isokinetic Speed Control can be used
to maximize strength gains while minimizing the potential for injury. The default Isokinetic
speed setting is 60 RPM.
As subjects exercise with Isokinetic Speed Control, they will quickly notice that you can go only
so fast. Once the selected speed is reached, increasing resistance results in increased stepping
resistance - try as they might, subjects can’t exercise any faster. On the other hand, if resistance
is lessened, the exercise resistance will decrease. This reflects the basic premise of Isokinetic
exercise: fixed speed with totally accommodating, variable resistance.
— 13 —
SELECTING THE RESISTANCE MODE
8. SELECTING AND CUSTOMIZING EXERCISE PROFILES
Just what is “totally accommodating, variable resistance?” Simply put, this means that at any
point in the range of motion (in this case, the stepping revolution) the resistance encountered by
the user will exactly match the force exerted. In other words, the harder one pushes on the
pedal, the greater the resistance. Maximum speed never changes and there is little or no resistance provided until the preset speed is achieved.
Because the BioStep Clinical Pro provides totally accommodating Isokinetic resistance for each
and every stepping revolution, fluctuations in force output are instantaneously accommodated.
Since the amount of resistance the musculoskeletal system must overcome can never exceed that
which it can produce at any point in the range of motion, the Isokinetic mode ensures extremely
safe and comfortable exercise for rehabilitation users.
SELECTING THE RESISTANCE MODE
— 14 —
8. SELECTING AND CUSTOMIZING EXERCISE PROFILES
The BioStep and BioStep Clinical Pro features five pre-programmed exercise protocols. These
can be used in conjunction with over 30 resistance levels for Constant Resistance Control or 20
speed settings for Isokinetic Speed Control applications (Clinical Pro only).
Each pre-programmed exercise protocol can be used as is, or can be customized by changing the
weight, time, speed or resistance level values. Modifying the <Set Time> value changes the total
time and the duration of each interval. Changing the Set Speed or Resistance Level increases or
decreases each interval. The minimum time for each profile is six minutes.
During the exercise, actual patient Resistance in WATTs is displayed on the Resistance Level Bar
Graph. The selected program resistance level or speed is displayed in the Exercise Window.
The Resistance Level Bar Graph provides both clinician and user with immediate, real-time
biofeedback, which helps make it easy for the user to stay within personal protocol guidelines
and for the clinician to be aware of the user’s level of resistance.
NOTE: Resistance may be changed while exercising. If changed, the new resistance becomes the basis for
subsequent levels.
The following sections define each exercise protocol and its potential applications.
NOTE: For all profiles of less than 10 minutes duration, the warm-up is one minute and the cool down is two
minutes. For profiles greater than 10 minutes duration, the warm-up and cool down are two minutes each.
CONSTANT RESISTANCE PROFILE EXAMPLES
All segments of the Constant Profiles are based on the work rate entered for the peak resistance
level work rate when you set Adjust Resistance Level. For example, if you enter “5” as the Peak
Resistance Level, the Constant Resistance (Manual Mode) profile will remain at “5” for the duration of the exercise session.
Minimum time for all profiles = 6 minutes.
Examples
With a Peak Resistance Level of “5”, a Constant Resistance (Manual Mode) Profile will appear
like the following example:
Peak Resistance Level: 5
Begin at 5
End at 5

9. HEART RATE MONITORING
HEART RATE MONITORING
The BioStep’s Heart Rate Monitoring feature allows clinicians to monitor user heart rate during
exercise sessions. This can be done using the heart rate contact handgrips, or by attaching the
wireless Polar heart rate monitor belt directly to the patient.
Heart Rate Contact Handgrips
To use the heart rate contact handgrips for heart rate monitoring, the patient needs only to grasp
both BioStep heart rate contact handgrips while exercising. The heart rate will be displayed in
real-time value in the upper display window. When the heart rate is being displayed, the heart
rate LED will be illuminated.
Wireless Heart Rate Chest Strap
The wireless Heart Rate Chest Strap is attached directly to the patient. When used, it sends heart
rate related information directly to the display panel.
To attach the Heart Rate Chest Strap directly to the patient:
1. Have the patient lift shirt and secure the Heart Rate Chest Strap around the chest so that it is
in direct contact with the skin just below the breast. (The strap should be dampened with a
conducting gel, sponge or wet cloth to ensure maximum conductivity.)
2. Position the patient on the BioStep and check that the heart rate information is being provided in the top window of the display panel.
HEART RATE CHART
As illustrated by the following chart, medical authorities have determined target heart rate
ranges for optimum cardiovascular benefit. While the chart may be used as a guide or starting
point, concessions must be made based on individual user needs.
CAUTION: As a general guideline, use the following equation in
estimating Maximum Heart Rate for a heart rate healthy user:
Maximum Heart Rate = 220 - user age in years
Example: A heart rate healthy 30 year-old would use a Max. H/R of 190 beats per minute.
ATTENTION: On ne do it jamais se servir de la pulsation cardiaque qui se rapproche de la limite
maximum de sécurité de la personne. Servez-vous de l’équation suivante comme guide pour estimer
la pulsation cardiaque maximum sécuritaire pour une personne en santé.
Pulsation cardiaque maximum = 220 - l’âge de la personne
Example: Une personne de 30 ans en santé et sane probléme cardiaque devrait s’en tenir à une pulsation cardiaque maximum de 190 par minute.
HEART RATE MONITORING
— 22 —
10. ADDITIONAL CONSIDERATIONS
NOTE: If the heart rate is not displayed, or appears to be incorrect, adjust the Heart Rate Chest Strap for
improved conductivity, or have the patient reposition both hands on the heart rate handle bar. (You may
want to take the user’s pulse rate manually and compare it against the displayed heart rate to confirm
accuracy. Eldery patients may need to use hand cream or water to improve signal strength.)
The following chart depicts standard Target Heart Rate ranges for optimum cardiovascular
benefit. While this chart may be used as a guide for heart rate-healthy users, clinicians must be
sure to set the Target Heart Rate based on individual patient protocol.
CAUTION: When prescribed for therapeutic purposes, a physician should clearly define the parameters of use (i.e., total work, maximum heart rate, etc.) to reduce the risk of patient injury.
ATTENTION: Quand l’appareil est untilisé en thérapue, le médecin responsable do it définir les
paramétres spécifiques en patient pour limiter tout rique et nnotamment le travail total et la
fréquence cardiaque.

10. ADDITIONAL CONSIDERATIONS
CAUTION: As with any other piece of user-interactive exercise equipment, certain considerations
must be ensured before anyone is allowed to exercise on the Biodex BioStep. Following is a brief
summary of some points to consider.
1. All users should have medical clearance prior to undertaking any rigorous exercise program. This is
especially necessary for any user with a past history of heart rate problems or known risk factors
including: family history of cardiovascular disease, elevated blood pressure, hyperlipidemia, diabetes,
obesity, sedentary lifestyle and smoking.
2. Start each user at a safe exercise level. Do not allow users to overexert themselves on the BioStep.
Symptoms of overexertion may include, but are not limited to: pain or discomfort, shortness of breath
or difficulty in breathing.
3. Prior to starting any exercise session, ensure that the user is comfortably seated. Be sure to adjust the
seat front-to-back and adjustment arm length as necessary. Mechanical adjustments are described in
detail in the Mechanical Adjustments section of this manual.
4. Warm-up and warm-down periods are necessary to avoid suddenly taxing the heart and circulation
system, and to help prevent injury to the muscles or joints. Sufficient warm-up and warm-down periods have also been shown to reduce muscle soreness following exercise. Be sure to allow for a minimum
of three to five minutes of gradually increasing exercise intensity prior to starting the actual exercise
session and a similar amount of time of decreasing exercise intensity following each session.
WHAT IS A MET?
The acronym MET stands for "metabolic equivalents"
METs are a unit of measurement that estimate the amount of physical demand placed on a person’s cardiopulmonary system. METs are often used in prescribing exercise for patients involved
in cardiopulmonary rehabilitation.
The MET level at which one exercises, is directly proportional to the amount of oxygen being
consumed, the amount of power (WATTs) accomplished, and the amount of calories burned
while exercising.
1 MET is equal to the amount of oxygen the body consumes at rest (lying down). The amount of
oxygen one consumes at rest is estimated to be approximately 3.5 ml of oxygen for each kilogram of body weight every minute or 3.5 ml/kg/min.
Each increase in energy expenditure of 3.5 ml/kg/min. is increasing one’s energy expenditure
by 1 MET.
MET charts have been developed by researchers to estimate the MET levels of domestic and
recreational activities. These estimations are generalizations as to how many times an individual
needs to elevate their metabolic rate (METs) to accomplish such activities.
The American College of Sports Medicine has published formulas to estimate the oxygen cost of
exercising at various work loads on treadmills, lower body cycles, upper body cycles, stepping,
and outdoor walking and running. MET levels can be determined by simply dividing oxygen
consumption in ml/kg/min. by 3.5.

CONTENTS
BIODEX ERGOMETERS SUPPORT METs AND AID EXERCISE PRESCRIPTION FOR
BOTH CARDIOPULMONARY AND MEDICAL FITNESS
A cardiac stress test typically reports the max MET level achieved by the patient and/or the
MET level achieved at the point the test turned positive (often demonstrating schemic changes
in the heart muscle and/or inappropriate arrhythmias). Cardiologists often ask therapists to
keep a patient below a certain MET level based on this information from the cardiac stress test.
The Cardiologist will report, for example, “schemic changes at 10 METs/Heart Rate 128.
Exercise at or below 9 METs”.
Different types of cardiovascular exercise machines require the user to work at different work
loads (WATTs) to ensure a consistent elevation of an individual’s metabolic rate and the corresponding appropriate heart rate. Cranking an upper body cycle at 100 WATTs will, for example,
have a very different effect on one’s metabolic rate and heart rate when compared to stepping a
lower body cycle at 100 WATTs. It is up to the clinician to set the appropriate workloads on each
ergometer, or speed and elevation on the treadmill, to achieve the appropriate MET level.
THE RELATIONSHIP OF CALORIES BURNED TO OXYGEN CONSUMPTION AND METs
For every liter of oxygen consumed by the body during exercise, the body burns approximately
5 calories. The example below shows a 150 lb (68 kg) individual exercising at a level requiring
an oxygen consumption of 1 liter (1,000 ml) of oxygen each min., which would require that they
burn 5 calories each min. to supply the appropriate amount of energy for the exercise. This same
individual would be burning 14.6 milliliters of oxygen for each kilogram of body weight per
min. (1,000 ml of oxygen / 68 kg of body weight). Since one MET = (oxygen consumption in
ml/kg/min.) / (3.5), this individual would be exercising at 4 METs. They would need to elevate
their resting metabolism approximately 4 times to achieve this sustain this rate of exercise.
4 METs
NOTE: In a study designed to examine the test-retest reliability and concurrent criterion validity of
VO2max on the BioStep in community-dwelling older adults, results provided preliminary evidence of
reliable and valid estimates of oxygen consumption by the BioStep when compared with the criterion
standard of direct VO2max measurement in the sample.

ADDITIONAL CONSIDERATIONS
CONTENTS
NOTA – Comme pour tout autre équipement d’exercice interactif avec l’usager, on doit s’assurer du
respect de certaines considérations avant de permettre à quiconque de s’exercer sur l’appareil
BioStep de Biodex. Voici un bref aperçu de certains points dont il faut tenir compte.
1. Tous les utilisateurs doivent recevoir une permission médicale avant d’entreprendre tout programme
d’exercices rigoureux. Cela est particulièrement nécessaire dans le cas de tout utilisateur ayant un historique de difficultés du rythme cardiaque ou de facteurs de risques connus, y compris : un historique
familial de maladie cardio-vasculaire, l’hypertension artérielle, l’hyperlipidémie, le diabète, l’obésité, un
mode de vie sédentaire et le tabagisme.
2. Au début, faire évoluer chaque utilisateur à un niveau sécuritaire d’exercice. Ne pas permettre aux
utilisateurs de se surmener sur l’appareil BioStep. Les symptômes du surmenage peuvent comprendre,
sans s’y limiter : la douleur ou le malaise, la respiration courte ou la difficulté à respirer.
3. Au début de toute séance d’exercice, s’assurer que l’utilisateur est assis confortablement. Veiller à
régler la position d’avance et de recul du siège, ainsi que la longueur du bras de réglage, selon le
besoin. On trouvera la description détaillée des réglages mécaniques au chapitre Réglages mécaniques
du présent manuel.
4. Des périodes d’échauffement et de récupération sont nécessaires pour éviter de surcharger subitement le
cœur et le système circulatoire et pour aider à prévenir les lésions aux muscles et aux articulations. Il a
été démontré que des périodes suffisantes d’échauffement et de récupération réduisent les douleurs
musculaires après l’exercice. Veiller à prévoir au minimum entre trois et cinq minutes d’exercices dont
l’intensité augmente graduellement avant le début de la séance d’exercice proprement dite, ainsi qu’une
période semblable d’exercices dont l’intensité va en diminuant après chaque séance.

QU’EST-CE QU’UN MET?
L’acronyme MET signifie « équivalent métabolique ».
Le MET sert d’unité de mesure pour estimer l’ Resistance demandé au système cardiopulmonaire d’une personne. On utilise souvent les MET pour prescrire des exercices à des patients
en cours de réadaptation cardiopulmonaire.
Le taux métabolique (en MET) auquel on effectue un exercice est directement proportionnel à la
quantité d’oxygène consommée, à la puissance développée (en WATTs) et aux calories brûlées
durant l’exercice.
Le MET correspond à la quantité d’oxygène que l’organisme consomme au repos (sujet couché).
On estime cette quantité à environ 3,5 millilitres d’oxygène par kilogramme de poids corporel
par minute, soit 3,5 ml/kg/min.
Chaque augmentation de 3,5 ml/kg/min de la dépense énergétique augmente la vitesse de
métabolisme de 1 MET.
Les chercheurs ont mis au point des tableaux où ils estiment le nombre de MET pour des activités domestiques et récréatives. Ces estimations sont des généralisations sur le nombre de fois
qu’une personne doit augmenter son taux métabolique (le nombre de MET qu’elle doit développer) pour effectuer ces activités.
L’American College of Sports Medicine publie des formules permettant de faire l’estimation de
la dépense en oxygène de l’exercice, sous diverses charges de travail, sur tapis roulant, sur
cycles pour membres inférieurs et pour membres supérieurs, de la montée-descente sur
escabeau, ainsi que de la marche et de la course à l’extérieur. On calcule le taux métabolique en
MET en divisant simplement la consommation d’oxygène (en ml/kg/min) par 3,5.
LES ERGOMÈTRES BIODEX FACILITENT LE CALCUL DES MET ET LES PRESCRIPTIONS D’EXERCICE POUR CARDIOPULMONAIRE ET MISE EN FORME SOUS
SURVEILLANCE MÉDICALE.
L’épreuve d’ Resistance cardiaque indique normalement le nombre maximal de MET atteint par
le patient, ou le nombre de MET au point où l’épreuve passe au positif (souvent avec manifestation de changements ischémiques dans le muscle cardiaque ou d’arythmies inappropriées). Les
cardiologues demandent souvent aux thérapeutes de maintenir le patient au-dessous d’un certain nombre de MET sur la foi de cette information, glanée de l’épreuve d’ Resistance cardiaque.
Dans son rapport, le cardiologue fait état, par exemple de « modifications ischémiques à 10
MET/fréquence cardiaque 128. Exercice à vitesse de métabolisme égale ou inférieure à 9 MET. »
Les différents types de machines d’exercice cardiovasculaire demandent à l’utilisateur des
charges de travail (en WATTs) différentes pour assurer une augmentation uniforme de la vitesse
de son métabolisme, ainsi que la fréquence cardiaque correspondante appropriée. Activer les
manivelles d’un cycle pour membres supérieurs à 100 WATTs, ou pédaler un cycle pour membres inférieurs à 100 WATTs, sont des activités qui ont de effets très différents sur la vitesse de
métabolisme et la fréquence cardiaque du sujet. C’est au clinicien qu’il revient de fixer les
charges de travail qui conviennent sur chaque ergomètre, ou la vitesse et l’élévation du tapis
roulant, afin d’atteindre le taux métabolique en MET approprié.

11. MAINTENANCE
RAPPORT ENTRE CALORIES BRÛLÉES, CONSOMMATION D’OXYGÈNE ET MET
Pour chaque litre d’oxygène consommé par l’organisme durant l’exercice, ce dernier brûle environ 5 calories. L’exemple ci-dessous illustre une personne de 68 kg (150 lb) s’exerçant à un
niveau qui demande une consommation de 1 litre (1 000 ml) d’oxygène chaque minute. Pour ce
faire, elle doit brûler 5 calories chaque minutes afin de fournir la quantité d’énergie appropriée à
l’exercice. Cette même personne brûle 14,6 millilitres d’oxygène pour chaque kilogramme de son
poids corporel par minute (1 000 ml d’oxygène / 68 kg de poids corporel). Étant donné que un
MET = (consommation d’oxygène en ml/kg/min) / (3,5), cette personne s’exerce à un taux de 4
MET. Elle doit augmenter son métabolisme au repos environ 4 fois pour atteindre et maintenir
ce taux d’exercice.

11. MAINTENANCE & CLEANING
The BioStep has been designed to provide many years of dependable use. To help ensure this
product performs to the maximum specifications, and to increase the life of the product, please
note the following general cleaning instructions and maintenance procedures.
1. As required, clean all exterior surfaces, upholstery and restraining straps. Specialized vinyl
cleaners or protectants are recommended for upholstery and cushions. Otherwise, use a solution of warm water and mild detergent.
2. As needed, wipe the display using a soft rag dampened with alcohol.
3. Lubricate the linkage bearings with lithium grease or oil as needed. Periodic lubrication of the
bearings will prevent them from becoming noisy. Lubricate the linkage bearings once a year
or every six months for heavy usage.
SUGGESTED METHODS FOR LUBRICATING LINKAGE BEARINGS
1. With the BioStep resting on its side, apply oil or grease to the outer race of the spherical bearings. Allow the BioStep to set for several minutes while the oil wicks to the opposite side. Lay
the BioStep on the opposite side and repeat. Return the BioStep to its upright position.
2. Axially rotate the linkage in question to expose the maximum amount of ball bearings and
race. Place the extension tube from the spray can of lithium grease between the linkage components and spray lightly. Repeat this for all 12 spherical bearings. Move the linkages in both
directions to ensure the grease wicks to the steel ball of the bearing.
3. Remove the set screws from within the lubrication port located on the ends of the cast links.
Insert the extension tube from the spray can of lithium grease into the port. While holding a
rag over the grease port to prevent spray back, spray lubrication into the bearings. The set
screws do not need to be replaced.
