    2. Identifying Parts & Adjustment Mechanisms Figure 1. Side View of BioStep 2 The BioStep 2 includes the following parts and adjustment mechanisms: 1. Display Panel 2. Seat Front-to-Back Release Handle (yellow) 3. Indexed Track 4. Seat Rotation Handle (blue) 5.

  • Page 6: Making Adjustments

    3. Making Adjustments With the BioStep 2, you can make the adjustments described below for easy access and correct positioning. Rotating the Seat (See Figure 3.) The seat can be rotated 90° in either direction. To rotate the seat, follow the steps below.

    Figure 5. Adjusting the BioStep 2 Arm Lengths Once you familiarize yourself with these adjustments, follow the steps below to assist users in getting on and off the BioStep 2, and to size the BioStep 2 so users can exercise comfortably.

  • Page 8: Easy-Size Instructions

    Easy-size Instructions 1. Place feet on the Footplates. 2. Adjust the seat distance. Lift the yellow handle and slide the seat forward along the track. The seat is positioned correctly when the user's knees are flexed slightly. NOTE: The knees should not be locked. 3.

  • Page 9: Operating The Biostep 2

    Use the BioStep 2 out-of-doors only in self-powered mode. When powered at work rates of at least 30 watts and 50 rpm, the BioStep 2 operates at low voltage (6 volts). 8. When exercising legs only and hands will not be on handgrips, it is recommended that armrests be in the up and away position and/or handgrips compressed into arms all the way.

  • Page 10: Powering Up The Biostep 2

    As long as the user pedals at a rate of at least 30 watts or 50 rpm, the battery continues to charge automatically. To power up the BioStep 2, simply begin pedaling or moving the arm cranks, or both. The Display Panel lights to indicate that the BioStep 2 is on.

  • Page 11: Exploring The Display Panel

    The BioStep 2 features 20 resistance settings numbered from one to 20. As the resistance level is raised from 1, the default, the effort that must be expended to pedal the BioStep 2 is increased. To change the resistance level, follow the steps below.

  • Page 12: Scrolling Through The Fitness Measurements

    Scrolling Through the Fitness Measurements During the exercise session, the BioStep 2 captures data in real-time for the following eight fitness measurements: WATTS→RPM→CALORIES→METS→STEPS→HEART RATE→DISTANCE STEPS keeps track of the number of elliptical rotations the BioStep 2 makes when the pedals or the arm cranks are moved. (See Section 6 for an explanation of METs, CALORIES, and WATTS.)

  • Page 13: Configuring The Biostep 2

    NOTE: DO NOT CHANGE THIS SETTING. Constant Resistance Control is the correct mode of operation for the BioStep 2. This mode is the perfect choice for heart rate and pulmonary rehabilitation, as well as general aerobic conditioning, because the resistance level remains constant regardless of pedaling speed.

  • Page 14: Monitoring The Heart Rate

    5. Monitoring the Heart Rate With the BioStep 2, clinicians can easily monitor a user's heart rate during exercising. Whether the user uses the Support Handgrips with Contact Heart Rate Monitoring located on either side of the seat (see Figure 1) or with their own provided Polar Telemetry Chest Strap, the heart rate is transmitted to the Display Panel and displays in real-time in the upper window when the HEART RATE LED lights.
  • Page 15 For example, for a heart-healthy, 30-year-old, the Maximum Heart Rate would be: 220 - 30 = 190 beats per minute CAUTION: When the BioStep 2 is prescribed for therapeutic purposes, maximum heart rate, as well as other fitness measurements, should be defined by a physician to reduce the risk of injury to the patient.

  • Page 16: Explaining Mets, Calories And Watts

    6. Explaining METS, Calories and Watts When you exercise, your body burns fat and releases energy or power. METs (Metabolic Equivalents), Exercise Calories, and Watts are terms that measure the amount of energy or power that is released. What are METs (Metabolic Equivalents)? METs, or metabolic equivalents, measure the rate of energy expended by estimating the amount of oxygen used by the body.

  • Page 17: What Are Exercise Calories

    Basal Metabolic Rate (BMR), to perform the activity. Because measurement of actual exercise intensity requires oxygen uptake monitoring equipment, Biodex can only estimate exercise intensity using standard formulas for different types of activity. Thus, Exercise Calories are also an estimate.

  • Page 18: Relationship Of Calories Burned To Oxygen Consumption And Mets

    NOTE: In a study designed to examine the test-retest reliability and concurrent criterion validity of VO2 max on the BioStep 2 in community-dwelling older adults, results provided preliminary evidence of reliable and valid estimates of oxygen consumption by the BioStep 2 when compared with the criterion standard of direct VO2 max measurement in the sample.

  • Page 19: Installation

    A minimum of two feet of free space along the sides of the BioStep 2 and at least six inches of free space at the front and rear of the BioStep 2 are recommended.
