Steady state exercise is widely used for psychophysiological studies in which a constant heart rate at a predetermined level is desired. We have developed a microcomputer servo‐controlled bicycle ergometer system that can be used for administering steady state exercise. Fourteen healthy male subjects, with a wide range of fitness levels (measured by Vo2max) were exercised to either a fixed workload (130 watts) or a predetermined heart rate level (servo‐heart rate) of 122 bpm (i.e., 65% of maximum calculated heart rate for the sample). Servo‐heart rate was implemented using a feedback loop that automatically adjusted workload to compensate for immediate variations in heart rate, resulting in a more consistent heart rate. Heart rate varied from the predetermined value by 17 bpm during fixed workload but only 3 bpm during servo‐heart rate (p |

Heart rate varied from the predetermined value by 17 bpm during fixed workload but only 3 bpm during servo‐heart rate (p<.05). Therefore, by using the microcomputer servo‐controlled bicycle ergometer, heart rate was maintained at a predetermined level regardless of the subject's fitness level. 2max and workload during servo‐heart rate were significantly correlated (r= .85, p<.05). Therefore, the workload necessary to maintain heart rate at a constant level may provide an approximate index of aerobic fitness level.</description><identifier>ISSN: 0048-5772</identifier><identifier>EISSN: 1469-8986</identifier><identifier>EISSN: 1540-5958</identifier><identifier>DOI: 10.1111/j.1469-8986.1989.tb03157.x</identifier><identifier>PMID: 2727222</identifier><identifier>CODEN: PSPHAF</identifier><language>eng</language><publisher>Oxford, UK: Blackwell Publishing Ltd</publisher><subject>Adult ; Bicycle ergometer ; Biological and medical sciences ; Exercise ; Exercise Test - instrumentation ; Fundamental and applied biological sciences.
