مستخلص: Background: The percentages of heart rate (%HRR) or oxygen uptake (%V̇O 2 R) reserve are used interchangeably for prescribing aerobic exercise intensity due to their assumed 1:1 relationship, although its validity is debated. This study aimed to assess if %HRR and %V̇O 2 R show a 1:1 relationship during steady-state exercise (SSE) and if exercise intensity and duration affect their relationship.
Methods: Eight physically active males (age 22.6 ± 1.2 years) were enrolled. Pre-exercise and maximal HR and V̇O 2 were assessed on the first day. In the following 4 days, different SSEs were performed (running) combining the following randomly assigned durations and intensities: 15 min, 45 min, 60% HRR, 80% HRR. Post-exercise maximal HR and V̇O 2 were assessed after each SSE. Using pre-exercise and post-exercise maximal values, the average HR and V̇O 2 of the last 5 min of each SSE were converted into percentages of the reserves (%RES), which were computed in a 3-way RM-ANOVA ( α  = 0.05) to assess if they were affected by the prescription parameter (HRR or V̇O 2 R), exercise intensity (60% or 80% HRR), and duration (15 or 45 min).
Results: The %RES values were not affected by the prescription parameter ( p  = 0.056) or its interactions with intensity ( p  = 0.319) or duration and intensity ( p  = 0.117), while parameter and duration interaction was significant ( p  = 0.009). %HRRs and %V̇O 2 Rs did not differ in the 15-min SSEs (mean difference [MD] = 0.7 percentage points, p  = 0.717), whereas %HRR was higher than %V̇O 2 R in the 45-min SSEs (MD = 6.7 percentage points, p  = 0.009).
Conclusion: SSE duration affects the %HRR-%V̇O 2 R relationship, with %HRRs higher than %V̇O 2 Rs in SSEs of longer duration.
