    FREECLIMBER 4400/4600 PT/CL CONSOLE THE FITNESS TEST PROGRAMS Understanding Submaximal Exercise Testing Before using the StairMaster 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 34 FREECLIMBER 4400/4600 PT/CL CONSOLE 150, external factors no longer influence heart rate, and a linear relationship exists. As the heart rate rises above 150, the heart-rate/oxygen uptake rela- tionship 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 exercis- ing to the point of volitional fatigue (i.e., exhaustion) during a graded exercise test.
  • Page 35: Pretest Screening

    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 heart rate response to the warmup.
  • Page 36 110 to 150 beats/min range to predict VO 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 minutes of each stage.
