Page 10 HEART RA TE MONITORING HEART RA TE INPUT The 7000 PT console uses telemetry (e.g., Polar ® ) heart rate signal detection. Ensure that your console is set up for telemetry signal detection only . There is a short “ lock out ” period at the beginning of each workout session during which the console first detects a signal and then validat[...]

Page 11 HEART RA TE MONITORING “TELEMETRY ONL Y“ - locks out contact heart rate signals and will only detect telemetry signals. Set your console to this default. “BOTH HR OFF“ - turns off the ability to detect any signal at all. Used in rare situations where there is excessive interference with the heart rate signals. This option turns off [...]

Page 20 The Fitness T est Programs Understanding Submaximal Exercise T esting Before using the StairMaster FreeClimber 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. • That a linear relationship exists betwee[...]

Page 21 150, external factors no longer influence heart rate, and a linear relationship ex- ists. 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 [...]
