Key result
A heart rate plateau (≤2 b•min−1) was achieved by 91% of participants and coincided with VO2max, suggesting it is a more accurate method to confirm true VO2max than other secondary criteria.
Why the study?
Does a heart rate plateau (∆HR≤2b•min−1) reliably confirm maximal oxygen uptake (V̇O2max) compared to other secondary criteria in young adults?
Population
11 young adults (mean age 22.4±3.21 years)
Comparison
Measurement of heart rate plateau, defined as… vs Other secondary criteria including respiratory…

Should not yet change VO2max verification protocols in young adults; leaves open prospective validation of heart rate plateau superiority.

Does a heart rate plateau (∆HR≤2b•min−1) reliably confirm maximal oxygen uptake (V̇O2max) compared to other secondary criteria in young adults?
A heart rate plateau of ≤2 beats/min over the final 60 seconds of exercise is a more accurate method to confirm true V̇O2max than other secondary criteria, potentially avoiding the need for an additional verification phase.
Keiller et al. (2018) reported an observational. Heart rate plateau (HRplat) vs. Other secondary criteria (RER, ΔRER, HRage) was evaluated on Achievement of HRplat coinciding with VO2max. A heart rate plateau (≤2 b•min−1) was achieved by 91% of participants and coincided with VO2max, suggesting it is a more accurate method to confirm true VO2max than other secondary criteria.
