Before leaving the StairMaster manufacturing facility in Tulsa, Oklahoma, your StairMaster ® Momentum cycle ergometer was thoroughly inspected and tested to ensure proper operation. The major parts of the StairMaster Momentum 3400 CE and 3800 RC are shown in Figures 1 and 2. Console Seat...
INTRODUCTION Figure 2: Major Parts, 3800 RC Throughout this manual, all references to the left or right side and to the front or back are made as if you were on the machine, ready to exercise. For example, the drive chain is located on the right side of the machine. The dimensions of the machine are listed in Table 1.
INSTALLATION INSTRUCTIONS Assemble your machine before use. Machines shipped outside the United States need to be uncrated before they can be assembled; refer to the “Uncrating Instructions” included with your machine for the details. Remove all shipping material and the battery charger from the machine.
BASIC OPERATING INSTRUCTIONS ADJUSTMENTS ® You should check two adjustments before using your StairMaster Momentum systems cycle ergometer: the seat and the pedal foot strap length. Seat Height Adjustment on the Momentum 3400 CE Sit on the seat. Put both feet onto the pedals and into the foot straps. Pedal slowly and then stop when one leg is extended and your foot is as close to the floor as possible.
BASIC OPERATING INSTRUCTIONS Foot strap Adjustment To ensure your feet are properly secured to the pedals, you need to check the position of the foot straps. Position your foot so that the ball of your foot is over the pedal spindle. The pedal foot straps should be tight enough to secure your feet to the pedals but not so tight so as to cut off the circulation.
BASIC OPERATING INSTRUCTIONS BASIC INSTRUCTIONS FOR FIRST-TIME USERS Warm up with light calisthenics and easy stretching exercises for at least five minutes before beginning your exercise program. WARNING IF AT ANY TIME DURING YOUR WORKOUT YOU FEEL CHEST PAIN, EXPERIENCE SEVERE MUSCULAR DISCOMFORT, FEEL FAINT, OR ARE SHORT OF BREATH, STOP EXERCISING IMMEDIATELY.
BASIC OPERATING INSTRUCTIONS Select an intensity level that allows you to stay at a comfortable pace. Harder is not always better. Exercise at a level that is consistent with your fitness level. Rest Periods You can stop and rest as many times as necessary for up to one minute for each rest period during all programs.
GENERAL EXERCISE GUIDELINES SETTING A GOAL The first step to a successful exercise program is to set realistic goals and objectives. Are you wanting an exercise program that is geared to build muscle, maintain muscle tone, or lose weight? In order to ensure that you fully receive all the benefits of a sound exercise program, you need to first identify the existence (if any) of risk factors that may influence the design of your exercise program.
-Maintenance Stage - 6 months plus; moderate to high intensity; moderate to high duration. *Note: Some of the material contained in this section is adapted from The StairMaster ® Fitness Handbook 2nd Ed. , James A Peterson, and Cedric X. Bryant (editors), Sagamore Publishing, 1995.
HEART RATE MONITORING HEART RATE INPUT ® Contact heart rate and telemetry (e.g., Polar ) heart rate signal detection is available. The default heart rate input option is "BOTH LOCKED." If a telemetry signal is detected first, contact heart rate signals are inhibited from being detected throughout the rest of the workout session and vice-versa.
HEART RATE MONITORING There are four options to handle heart rate input signals. Press the [SELECT] key to scroll through the options until you find the one option that suits your needs. Press the [ENTER] key to select that option. “...
Heart rate monitoring is not possible. TELEMETRY HEART RATE ® ® The StairMaster Momentum features telemetry (Polar ) heart rate monitoring. The system consists of the receiver, located on the stepper, and a transmitter belt (purchased separately) worn across your chest. The monitoring function is activated as soon as you strap on the chest belt and step within range of the receiver in the machine.
Do not use abrasives or chemicals such as steel wool or alcohol for cleaning, as they can damage the electrodes permanently. You can order replacement belts from StairMaster, Polar Electro, Inc., or your local fitness store: StairMaster 800-331-3578 P/N 64000 Polar Electro, Inc.
CONTACT HEART RATE CONTACT HEART RATE ® The StairMaster Momentum features a digitized contact heart rate monitoring system. Through the use of stainless steel sensors built into the upper handles and sophisticated software, heart rate can be checked at any time during a workout.
MOMENTUM SYSTEMS CONSOLE ® The StairMaster Momentum systems console is divided into seven sections: the display window, the workout options, the numeric keypad, the entertainment keypad, the workout statistics, the stop key, and the intensity level keys (see Figure 5).
Page 26
MOMENTUM SYSTEMS CONSOLE NUMERIC KEYPAD The numeric keypad is located on the right side of the console. Before the exercise program begins, the numbers are used to enter data in response to the console prompts. • Enter - Confirms workout selections and stores the informa- tion used by the console to calculate workout statistics.
MOMENTUM SYSTEMS CONSOLE Workout Statistics During the exercise program, the Stats keys are used to track workout statistics which are then shown in the display window.

The Fat Burner Program The Fat Burner program is a 60-interval workout designed for people just starting a weight control program. The relative intensity level is indicated on the profile and any changes in the intensity level will continue for the remainder of the program.
MOMENTUM SYSTEMS CONSOLE during an EXERCISE interval. The intensity level shown during an EXERCISE interval is indicative of your current speed. However, the current speed during a REST interval is equal to a scaled percentage of the displayed intensity level. Note that the program profile does not change at any time during the workout session.
MOMENTUM SYSTEMS CONSOLE THE FITNESS TEST PROGRAMS Understanding Submaximal Exercise Testing ® Before using the StairMaster Momentum for submaximal exercise testing, it should be noted that all submaximal fitness tests make several assumptions: • That a steady-state heart rate is obtained for each exercise workload.
Page 32
MOMENTUM SYSTEMS CONSOLE no longer influence heart rate, and a linear relationship exists. As the heart rate rises above 150, the heart-rate/oxygen uptake relationship becomes curvilinear. The third assumption involves maximal heart rate. Maximal heart rate is the greatest heart rate that can be measured when an individual is exercising to the point of volitional fatigue (i.e., exhaustion) during a graded exercise test.
The StairMaster Submaximal Fit Test The StairMaster branching protocol is a series of 3-minute stages of continuous exercise at increasing intensity. The first stage is a warmup at approximately 4 METs. The intensity of the remaining stages is based on the...
115 to 150 beats/min range to predict VO 2max The test typically lasts from 9 to 15 minutes. In the StairMaster protocol, each work rate is performed for 3 minutes, with heart rates recorded during the final 4 seconds of the 2 and 3 minutes of each stage.
Turning on the StairMaster Fitness Test The StairMaster fitness test may be taken using either a chest strap (telemetry), or by using the specialized contact heart rate grips. 1.
