3. HEART RATE ZONE TRAINING EXERCISE

3.1 HEART RATE ZONE TRAINING EXERCISE
 Research shows that maintaining a specific heart rate while exercising, is both the optimal
way to monitor the
 intensity of a workout and to achieve maximum results. This is the concept behind a heart
rate zone training
 approach to exercise. Zone Training identifies an exerciser's ideal heart rate range, or zone,
for burning fat or
 increasing cardiovascular fitness. The values within the zone depend on the workout.


 NOTE: Consultation with a fitness trainer is recommended for defining specific fitness goals
and designing a
      suitable workout program.


 The four bike workouts, Fa t Bu rn, Cardio, Target Interval, Target Hill are designed to take full

 3.2.2 T he P olar® te lemetry heart rate monitoring chest s trap (Or similar compatible item)
 The bike is equipped with Polar® telemetry, a heart rate monitoring system in which electrodes are
 pressed against the skin, and transfer heart rate signals to the bike console. These electrodes are
 mounted in the chest strap that is worn during the workout. The chest strap is an optional extra,
 to order call your local distributor or supplier.
 See the diagram below for correct positioning of the strap. The electrodes (A) which are the two
 grooved surfaces on the underside of the strap, must remain moist to transmit accurately the
 electrical impulses of the heart back to the receiver. Moisten the electrodes or apply a conductive
 gel. Secure the strap as high under the chest muscles as possible. The strap should be snug, but
 comfortable enough to allow for normal breathing.

                                                           The transmitter strap delivers an optimal heart

4 THE WORKOUTS

4.1 WORKOUT OVERVIEWS
This section lists the Bike’s preprogrammed workouts. For more detailed information,
see Section 4.2, titled ‘Using the Workouts’.


4.1.1 Quick S tart
 This is the fastest way to begin exercising, and it bypasses the steps involved in
 selecting a specific workout program. After the Qu ick S tart key is pressed, a constant level
 workout begins. All intensity levels are changed manually they not change automatically..


4.1.2 Manual

 As Qu ic k S tart - this is a workout in which the intensity levels are change manually.




4.1.3 Preset Program


• In te rval is a Hill workout in which intensity levels rise and fall. The higher levels gradually
  incline toward a peak and then gradually decline.




 • Hill is an interval training workout combining ‘hills’ and ‘valleys’ with ‘hills’ of different intensity levels,
   and is proven to provide effective, time efficient cardiovascular results.




                                                    16
4.1.3 Preset Program
Con t.
  • M ountain is a Hill workout in which the intensity levels gradually incline toward one ultimate
     peak and then gradually decline.




   • P ower is a Hill workout in which the intensity level alternates between high and low levels
       very quickly to simulate a typical speed-training (interval) workout.




4.1.4 Heart R ate Program
  T h e user must wear a Polar® heart rate chest s trap, or grasp th e pulse system sensors c ontinuously.

  • Fa t Burn
    This is a low intensity workout for burning the body’s fat reserves. The workout program
     automatically adjusts the intensity level, based on the actual heart rate. The user selects the
     intensity level from 50 to 65 percent of the theoretical maximum (MHR).




                               Us er example : 35 y ear old (MHR 185) 65% M HR,




                                                 17
• M a x imum Heart R ate (MHR) : Defined by the American College of Sports Medicine's
  "Guidelines for Exercise Testing and Prescription" as equal to 220 minus an individual ’s age.




• T a r get Heart R ate (THR) : This is a percentage of the theoretical maximum.
   For example, a 35 year old user's THR for the CAR DIO workout is 148.
   This workout targets 80 percent of the maximum, so the equation would be 0.8(220 -35) =148.




   Programs that calculate a THR base this number on the age of the user and the type of workout.
   The user accepts or adjusts the rate when setting up the workout. During the workout itself, the
   program reads the heart rate, which is transmitted via the Polar ® heart rate chest strap or the
   pulse system sensors; and it uses this data to adjust the resistance. Manually raising the rate
   increases the intensity of the cardiovascular exercise.




   • Ca r dio
      This is a higher intensity workout for more fit users, emphasizing cardiovascular benefits and
       maximum fat burning. The workout program automatically adjusts the intensity level, based on
       the actual heart rate. The user selects the intensity level from 70 to 80 percent of the
       theoretical maximum (MHR).




                               Us er example : 35 y ears old (MHR 185) 80%
                               M HR




                                                     18
• T arget Interval
   The workout consists of three hills that target three heart rate goals. The first hill brings
the heart rate
   to 70 percent of MHR. The second hill increases the rate to 75 percent of MHR. The
third hill brings the
   heart rate to 80 percent of MHR. The valley always is defined as 65 percent of MHR.




                        Us er example : For a 35 y ear old (MHR 185) 70,75 &
                        80 %

 • T arget Hill
   This workout alternates between two target heart rates as quickly as possible.
    When setting up the workout, the user enters a target maximum heart rate. After a three minutes
    warm-up, the Intensity will increase, until the user reaches the 85 percent of MHR. Then,
    the intensity decreases, until the heart rate falls to the 65 percent of MHR. The program
    repeats these alternating intensity levels.




                            Us er example : 35 y ear old (MHR 185) 85%
                            M HR,

4.3 FITNESS TEST
The Fitness Test workout measures cardiovascular fitness and can be used to monitor improvements
in endurance every four to six weeks. The user must grasp the pulse sensors when exercising or wear
a heart rate chest strap, as the test score calculation is based on a heart rate reading.
The workout consist of three steps, 2 minutes warming up, 6 minutes workout, 2 minutes cool down.


The Fitness Test is considered to be a sub-max VO2 (volume of oxygen) test. It gauges how
well the heart supplies oxygenated blood to the exercising muscles, and how efficiently those
muscles receive oxygen from the blood. Physicians and exercise physiologists generally regard
this test as a good measure of aerobic capacity.


Please note that the estimated VO2 max scores achieved will be 10 percent to15 percent lower on
stationary exercise bikes than those achieved on treadmill.
Stationary cycling has a higher rate of isolated muscle fatigue of the quadriceps when compared
to walking/running on a treadmill, climbing on a stair climber, or utilizing a cross -trainer.
This higher rate of fatigue corresponds to lower levels of estimated VO2 max scores.


4.3.1 T o set u p the Fitness Test
- Press the Fitn ess T est.
- Enter the user’s age and gender as the monitor’s message.
- The message center displays the prompt, ‘DO YOU EXERCISE 3 TIME PER WEEK DURING
  LAST 3 MONTHS? 1. CONDITIONS 2.UNCONDIT IONS ’
  Select 1. or 2.
- Enter the use’s weight.
- The console commences the workout.
- The console will read the user's heart rate, calculate a fitness score, and display the score
  in the MESSAGE CENTER.


Note : To receive a proper Fit Test score, the work must be done within a training zone.
       That is 40/60 RPM (average 50 RPM) pedaling. The message center displays RPM, and
       the workout profile displays shapes, made of columns of lights, that represent the range
       of RPM.




                                                   25
                                             50




After the ten minutes, Fitness Test is completed and a Fitness Test score will be displayed.


The console will not accept :
- Heart rates less than 52 or greater than 200 beats per minute
- Body weights less than 75 pounds (34 kg) or greater than 400 pounds (182 kg)
- Ages below 10 or over 99 years
- Input data that exceeds human ability.


4.3.2 Important measuring instructions
 It is important to take the Fitness Test under similar circumstances each time. The heart rate is
 dependent on many factors, including:
- Amount of sleep on the previous night : at least seven hours is recommended
- Time of a day
- Time you last ate : two to four hours after the last meal is recommended
- Time since you last drank a liquid containing caffeine or alcohol, or smoked a cigarette :
  at least four hours is recommended
- Time since you last exercised : at least six hours is recommended


For the most accurate Fitness Test results, you should perform the Fitness Test on three
consecutive days and average the three scores.




                                                  26
NOTE: To receive a proper Fitness Test score;
      1. The work done must be within a training heart rate zone that is 60 percent to 85
          percent of the theoretical maximum heart rate.
      2. The work done must be within a regular pedaling RPM zone that is ± 10 of 50 RPM.

6.3 TROUBLESHOOTING THE POLAR HEART RATE CHEST STRAP

HEAR T R ATE R EADING IS ERRATIC OR ABSENT ENTIRELY
 - Repeat the electrode moistening procedure.
   The electrodes must remain wet to pick up and transmit accurate heart rate readings.
 - Make sure the electrodes are flat against the skin.
 - Wash the belt transmitter regularly with mild soap and water.
 - Make sure the chest strap transmitter is within three feet, or one meter, of the heart rate
   receiver.
 - The chest strap is battery-operated and will stop functioning when the battery runs out.
   Contact JNB S PORTS or your Distributor for instructions on how to have the chest
   strap replaced.


HEAR T R ATE R EADING IS ERRATIC OR EXTREMELY HIGH
 If the chest strap is worn near sources of electromagnetic signals, these signals may be
 strong enough to affect heart rate readings.
 Possible sources include:
 - Television sets and/or antennas, cell phones, computers, cars, high voltage power lines
   and motor driven exercise equipment.
 - Another heart rate transmitter within three feet, or one meter, may also cause abnormal
   heart rate readings.



6.4 TROUBLESHOOTING THE PULSE SYSTEM SENSORS
 If the heart rate reading is erratic or missing, do the following:
 - Dry moist hands to prevent slipping.
 - Apply hands to both sensors, one in each hand.
 - Grasp the sensors firmly.
 - Apply constant pressure around the sensors.


6.5 RECYCLING THE BATTERY
When this bike is about to be discarded at the end of its useful life, the rechargeable battery
must first be removed and recycled. If an optional external power supply is present, it must be
disconnected before the battery is removed. To access the battery, remove the right-side
pedal crank and shroud. To remove the battery, disconnect the cable, and remove the two
screws holding the battery to the bracket
