Description

The purpose of this study was to investigate the reliability of the new evaluation method for exercise work by controlling pedaling torque to a constant heart rate level during exercise. Ten healthy subjects with no history of bone and joint injury volunteered to this study. They underwent two trials, 18 minutes each, at 50 cadences per minute in the new method. HR, mechanical work, oxygen consumption (VO₂), systolic blood pressure (SBP), and ratings of perceived exertion (RPE) were measured during the exercise. The coefficient of variation (CV) was calculated as an index of HR regulation. Reliability for each variable was assessed by calculating intra-class correlation coefficients (ICC). The average for HR during exercise was nearly equal to the target HR, and the CV was from 1.7% to 1.9%. A good test-retest reliability was obtained in mechanical work, VO₂, SBP and RPE, showing ICC values of 0.95-0.97, 0.96-0.99, 0.97, 0.94, respectively (p < 0.01). In conclusion, this evaluation method for exercise work is reliable and valuable and can be clinically applicable in terms of frequent assessment without any volitional fatigue.
