  • Page 9: Introduction

    INTRODUCTION OVERVIEW The Monark 839 Electronic Ergometer is a complex structure of mechanical equipment under the control of an elaborate computer system. The computer provides a fine element of control which was not possible to obtain using strictly mechanical devices.

    INITIAL OPERATION Although all 839 ergometers are 100% calibrated at the factory, the user may wish to verify this by performing the mechanical calibration of the pendulum weight. See section “Mechanical Reference, Cali- bration of Pendelum Weight”.

  • Page 12: Testing With The 839 Ergometer

    TESTING WITH THE 839 ERGOMETER PERFORMANCE VALIDATION The 839 is a mechanically weighted and braked ergometer, making performance validation a simple pro- cedure. The work performed on the ergometer is the product of the weight lifted times the numbers of revolutions (factored).

  • Page 13: General

    CALIBRATION ELECTRONICS Calibration is necessary to match the mechanics of the ergometer to the electronics of the computer. The following steps are required to recalibrate the electronics to the pendulum scale. 1. Check at the bottom of the flywheel that the brake belt is loose. If not move the pendulum up to 3 kp and hold it for a few seconds.

  • Page 14: Preparation For Testing

    PREPARATION FOR TESTING The versatility of the 839 Electronic Ergometer enable it to be utilised in a variety of testing environments. The precision and reproducibility of measurements made with the ergometer in conjunction with the ease of testing, allow it to be employed in clinical exercise stress facilities, corporate fitness programs and health clubs.

  • Page 15: Subject Supervision

    HEART RATE: ELECTRODE-BELT AND EAR PLETHYSMOGRAPH The subject’s heart rate can be monitored by chest belt telemetry system or by an ear clip which measures heart rate by light transmission through the ear. Only the system with chest belt electrodes is standard equipment.

  • Page 16: Reviewing Results

    The subject may also show difficulty in regulating the speed of the ergometer. The power will be properly regulated regardless of the speed, assuming that the protocol work type is not force and that the speed is maintained above the pedal low setting (default is 30 RPM). In addition , some subjects may become sensitive to the display on the handheld remote controller.

The computer controller for the 839 Ergometer can preform different protocols in addition to strict manual operation. Four protocols have been preset and 2 are partly preset . Several preprogrammed protocols measure oxygen consumption at steady state: the Astrand, using a single workload, the YMCA, using multiple branching workloads (“YMCAs Way to Physical Fitness”...

  • Page 22 ASTRAND PROTOCOL The Astrand protocol is designed to determine maximal oxygen consumption by exercising the subject at a submaximal workload and measuring the steady state heart rate. The workload, in conjunction with the result- ant heart rate, is compared to the predicted relationship, adjusted for age and sex and a maximal oxygen con- sumption is computed.

  • Page 25 YMCA PROTOCOL - “Y´S WAY TO PHYSICAL FITNESS” The YMCA protocol is based on the “Y´s Way to Physical Fitness” bicycle test. The design is a submaximal test, using branching multiple workloads in which the next workload is determined by the steady state heart rate elicited by the previous level.
  • Page 26 BRUCE PROTOCOL Bicycle ergometers measure total oxygen consumption relatively independent of body weight. Since the sub- ject’s body weight is supported by the saddle, the total work performed is a function of only the resistive force and the pedal speed. At the same power setting, all subjects will have approximately the same oxygen con- sumption.
  • Page 27 NAUGHTON PROTOCOL The standard Naughton Protocol (reference 5) is a two minute incremental test. The test is extremely similar to the Bruce protocol with two simple exceptions: the stages are two minutes in duration instead of three and the incremental V02 between stages is linear (3.5 ml/kg/min). The stages represent discrete oxygen consumption levels generally referred to as “METS”.

    MANUAL USE Begin to put in personal data like sex, weight, age and max. heart rate. Workload - Force setting The workload can be set in Newtons(N) or kp. Power is in this mode depending on the pedal rpm. Workload can be increased or decreased with keys 7/4, 8/4 and 9/5.
  • Page 29 Workload - HR related. The Heart Rate program is designed to adjust the workload in an attempt to maintain a desired heart rate. This is achieved by increasing the workload from zero, at the start, using incremental steps. How fast the power is adjusted is depending on howfar away the actual heart rate is from the desired heart rate.

  • Page 30: Work Test

    WORK TEST INCREMENTAL PROTOCOL The incremental protocol consists of a series of workloads which are constantly increasing with time. Under control of the incremental, the ergometer exercises the subject to a maximum workload. The rate at which the workload rises is presetable. The type of work: power or force may also be preset as desired.
