Getting Started on Your Bike RIDING YOUR BIKE SETTING YOUR WEIGHT Set your weight before every workout. This allows the Z8 Bike to control your workout more effectively. See the Personal Power section in Chapter 4 for more information.
Riding Form RIDING YOUR BIKE FOOT POSITION RIDING YOUR BIKE Riders are most efficient if they place the ball of their foot in the center of the pedal. 16 Other riders are more comfortable if the arch of their foot is against the pedal. Riders are encouraged to be as efficient as possible, but use your own judgement in the comfort/efficiency tradeoff. Most riders will find a comfort/efficiency sweet spot at a pedal cadence around 80 rpm.
Monitoring Your Heart Rate RIDING YOUR BIKE MONITORING YOUR HEART RATE The Z8 Bike has two ways of monitoring your heart rate: ...By using a chest strap that transmits your heart rate to the bike via radio... Upright Upper HRC Pads Upright Lower HRC Pads RIDING YOUR BIKE ...or by using the metal contact heart rate pads on the handlebars.
Chest Strap Use RIDING YOUR BIKE RIDING YOUR BIKE When you wear a Polar or compatible transmitter strap, the bike will display your heart rate as a digital beats-per-minute (bpm) readout. This monitoring is very accurate, typically within one beat per minute. The transmitter strap should be worn directly against your skin, about one inch below the pectoral muscles/breast line (see picture below). Women should be careful to place the transmitter below their bra line.
Contact Heart Rate Use RIDING YOUR BIKE CONTACT HEART RATE (CHR) The contact heart rate system lets you monitor your heart rate without wearing a strap. A Note on CHR Accuracy The Z8 Bike uses the most advanced CHR system available. It converts your heart rate waveform to a digital signal, then analyzes the digitized waveform to pick out the electrocardiogram shape and thus the heart rate. When the system detects your hands, the heart rate LED will flash in time with your heart beat.
Getting the Most From CHR RIDING YOUR BIKE 1. Exercise with smooth body motions. Avoid excessive body motion, especially in your arms and upper body. FOR BEST RESULTS RIDING YOUR BIKE 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.

Personal Power HOW THE BIKE CONTROLS YOUR EXERCISE PERSONAL POWER On average, bigger people can produce more power. Also, it's desirable to have the same workout program or workout level feel the same to riders of different sizes. Personal Power is a new kind of control system that makes the Z8 Bike feel the same to every rider. This system is used in almost every workout program. Personal Power works by adjusting workload for each level based on body weight entered by the rider.
Workload Control Details HOW THE BIKE CONTROLS YOUR EXERCISE Different size riders cause Personal Power to shift the workload value for each level (in Manual) or the entire program profile (in pre-set programs) up or down. This means the lowest available workload for a 300-pound rider is higher than a 150-pound rider. Also, the differences between levels are greater for a larger rider. (Also see Chapter 7, page xx.

Introduction to HRC HEART RATE CONTROL CONSTANT HRC True's heart rate control (HRC) workouts let the bike 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.
Types of HRC HEART RATE CONTROL The Z8 Bike has five types of heart rate control: Constant: pick a target heart rate, and the bike will control your workout from the very beginning so that you reach your target within five to seven minutes. Interval: pick both a work target and a rest target heart rate. The bike will take you back and forth between these two targets.
Constant and Interval HRC HEART RATE CONTROL CONSTANT HRC This is the best-known type of HRC, and is the easiest to use. The bike will gradually raise your heart rate so that you reach your target within five to seven minutes. It keeps you there until 2.5 minutes before the end of your workout time, then reduces workload by half for a cooldown. Note that as you tire during your workout, especially in the last third, workload will usually have to be reduced to keep you at a steady target heart rate.
HRC Ultra Overview HEART RATE CONTROL As mentioned in the Constant HRC section, as you tire in the last third of your workout, your heart rate has a tendency to rise, which Constant HRC addresses by reducing workload. However, exercisers who are really serious and in very good condition always let their heart rates rise during the last third of their workouts, usually to very high levels. The HRC Ultra workouts are designed to simulate this kind of high-intensity workout.
HRC Ultra Workout HEART RATE CONTROL HRC ULTRA WORKOUT Unlike Constant and Interval HRC, you don't pick a target heart rate, but you must enter your age correctly. For the first fifth of your workout time, HRC Ultra tries to increase your heart rate to 70% of your maximum heart rate (HRmax) within three to four minutes. In the middle three-fifths of your workout, HRC Ultra increases your heart rate to 88% HRmax within three to four minutes, then held there.
Interval HRC Ultra Workout HEART RATE CONTROL Interval HRC Ultra works similarly to Interval HRC, but the work target heart rates gradually increase through your workout. The first work segment target is 88% HRmax, and the last work segment target is 97% HRmax. HEART RATE CONTROL The rest segment target is 65%. Note that workload usually has to be greatly decreased to allow you to reach this low a heart rate within a desirable time.
Cruise Control HEART RATE CONTROL CRUISE This is the simplest way to enter Constant HRC training. While CONTROL in manual or any program you can enter Constant HRC by simply pressing the Heart Rate Control 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.
Important Points About HRC HEART RATE CONTROL The heart rate monitor transmitter strap should be worn according to the guidelines in Chapter 2. If the transmitter strap is adjusted or moved while exercising, heart rate monitoring may be temporarily affected. HEART RATE CONTROL If communication is lost for 30 seconds, the bike will exit the HRC workout into a manual workout.

Setting Up a Calorie Goal Workout CALORIE GOAL WORKOUT SETTING UP A CALORIE GOAL WORKOUT Calorie Goal lets you pick a total number of calories and workout time, then calculates a steady-state exercise at a work level (Cruising Watts) so that you reach your target total calories at the end of a 2.5-minute cooldown. There is a 2.5minute warmup prior to Cruising Watts. Calorie Goal is especially useful if you exercise to help with weight loss or weight control.

Introduction and How to Test Yourself FITNESS TEST The Z8 Bike fitness test is an improved implementation of the YMCA protocol fitness test, as described in the ACSM Guidelines, Chapter 4. (See Bibliography.) The bike must monitor your heart rate accurately throughout, so you should use a wireless transmitter strap instead of the contact heart rate pads (see Chapter 2). It works best with the external power option.
Proper Preparation and Behavior FITNESS TEST FITNESS TEST You should: Stay as relaxed as possible during the test, breathing smoothly and regularly. Be dressed in comfortable workout clothes and riding in a room with comfortable air temperature and humidity. You should not: Eat within three hours prior to testing, but you should not be hungry, either. Consume caffeine within three hours prior. Smoke within three hours prior. Exercise vigorously within 24 hours prior.
How the Test Works FITNESS TEST The test consists of four three-minute stages. Stage one is a warmup stage. Stages two, three, and four are at everincreasing workloads, with your heart rate measured during the second and third minute of each stage. (If the two heart rate samples in a given stage are separated by more than six bpm, that stage is extended for an additional minute.
How to Use Your Results FITNESS TEST FITNESS TEST The best way to use the results of a fitness test is to track your progress in an exercise program. Test yourself about every two weeks, under closely similar conditions. You can also use the results of a fitness test to find how you compare with an average population. Find your score in the chart below in the proper column for your age group. (Data is from ASCM Guidelines, from 1994 research from the Institute for Aerobics Research in Dallas, Texas.
Test Specific Issues FITNESS TEST Note that the absolute accuracy of this test is approximately + /- 15% compared to a laboratory maximal test. (See Swain and Leutholtz, Metabolic Calculations, page 63). The results on the Z8 Bike should be somewhat better since it uses an improved maximum heart rate formula (see Appendix A). The repeatability accuracy, from test to test with the same test subject, should be much better, probably within +/- 7%.

One use of Happy Workout is to allow easier IN/OUT demonstration of the bike to serious riders.
chapter fourteen Creating an Exercise Plan In This Chapter: The F.I.T. Concept Defined Utilizing the F.I.T. Concept Beginning Your F.I.T.
The F.I.T. Concept Defined DESIGNING AN EXERCISE PROGRAM WHAT IS THE F.I.T. CONCEPT? 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.
More F.I.T. Concept Overview DESIGNING AN EXERCISE PROGRAM regular exercise. Never exceed your target heart rate zone. Increase the workload on the bike to raise your heart rate to the level recommended by your doctor. 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.
Utilizing the F.I.T. Concept DESIGNING AN EXERCISE PROGRAM USING THE F.I.T. CONCEPT YOUR FITNESS PROGRAM DETERMINING YOUR NEEDS The F.I.T. concept is 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 Z8 Bike. Using the bike regularly may increase the ability of your heart and lungs to supply oxygen and nutrients to exercising muscles over an extended period of time.
Beginning Your F.I.T. Program 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 Appendix A reflect averages.
Your F.I.T. Program Continued 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 exercising smoothly. Cool-Down: Slow and Relaxed Exercise Cooling down relaxes your muscles and gradually lowers your heart rate.
Establishing and Maintaining Fitness DESIGNING AN EXERCISE PROGRAM 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. ESTABLISHING AEROBIC FITNESS 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.
Weight Management DESIGNING AN EXERCISE PROGRAM MANAGING WEIGHT 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.
A Sports Training Program DESIGNING AN EXERCISE PROGRAM 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. DESIGNING AN EXERCISE PROGRAM Warning: these strategies are intended for average healthy adults.

appendix a Appendix A Maximum Heart Rate and Target Heart Rate Z8 Bike Owner’s Guide 143
Appendix A TARGET HEART RATE CHART APPENDIX A Z8 Bike Owner’s Guide 145
Appendix A Remember to check with your physician before beginning any exercise program. She can help determine an appropriate target heart rate. Medications often affect heart rate. CHECK WITH YOUR PHYSICIAN Robert Robergs, editor of the prestigious Journal of Exercise Physiology, conducted a study in 2002 of the maximal heart rate equation 220 - age. He found this equation "has no scientific merit for use in exercise physiology and related fields.
appendix b Appendix B Maximal Oxygen Uptake and METs Z8 Bike Owner’s Guide 149
Appendix B VO2MAX Maximal oxygen uptake, or VO2max, is considered the best single measurement of cardiovascular fitness. It represents the peak rate of your body's oxygen consumption capability, which is important because this is one of the two biggest factors in endurance performance. (The other big endurance factor is the lactate threshold, which is the exercise level at which blood lactate begins to accumulate above resting levels.
Appendix B METs are defined as the ratio of the current body energy expenditure rate compared with basal metabolic rate (BMR): METs = (VO2 rate of current state) / 3.5 APPENDIX B where 3.5 represents BMR. VO2 (oxygen uptake) and 3.5 are in units of ml/kg/minute of oxygen consumed by the body. This oxygen consumption rate corresponds to about 72 calories per hour for a 150-pound person.
appendix c Appendix C Details on How the Z8 Bike Controls Your Exercise Intensity Z8 Bike Owner’s Guide 155
Appendix C As you ride the Z8 Bike, your exercise intensity is best POWER AND measured as the amount of power received by the bike from CONSTANT your pedaling. This power is usually expressed in watts. The TORQUE watts measurement is calculated from your pedaling speed (called cadence) multiplied by the amount of resistance on the pedals (called torque). (See Feynman, Lectures on Physics, 1971.
APPENDIX C Appendix C Constant torque is used in a modified way in Bike Mode. In addition to constant resistance for a given "gear," additional torque is applied to simulate wind and road resistance, as well as to compensate for different body weights. Personal Power was initially designed to vary workload at a 1:1 ratio with body weight, just like a METs-based exercise prescription.
appendix d Appendix D American College of Sports Medicine Position Stand on Exercise and Fitness Z8 Bike Owner’s Guide 161
Appendix D INTRODUCTION In 1998, the American College of Sports Medicine completed their most important position stand, titled, "The recommended quantity and quality of exercise for developing and maintaining cardiorespiratory and muscular fitness in healthy adults." The ACSM is recognized as the premier authority in this area, so this document describes the current consensus among exercise physiologists and coaches. The following is a summary of the document.
Appendix D APPENDIX D Training should be three to five days per week at between 55% and 90% maximum heart rate. Deconditioned individuals should stay between 55% and 64%. Total duration of training should be between 20 and 60 minutes, with the time varying inversely with intensity. High-intensity, short duration exercise is generally only recommended when training for non-athletic competition.
