Abstract

This study investigates heart rate (HR), in 11 young adults (22.4±3.21yr), at O2max, to ascertain whether measured maximal heart rate (HRmax), as determined by a plateau in HR (HRplat), can reliably confirm O2max. O2max and HRplat were determined, using the parameters of a O2 ≤50ml•min-1 and a ∆HR≤2b•min-1, respectively, over the final 60s of sampling. O2max was also independently determined using a verification phase protocol. A HRplat was achieved by 91% of participants (∆HR=1.3±1b•min-1) and critically the time at which HRmax was reached coincided with that at which O2max was achieved. Moreover RER and ΔRER criteria were reached significantly earlier (p<0.05) than O2max, whilst age-related heart rate maximums (HRage), were not achieved by many participants. The results suggest that a HRplat ≤2 b•min-1 is a more accurate method, within the group tested, to determine whether a ‘true’ O2max has been achieved, than other secondary criteria and potentially avoids the requirement for an additional verification phase.
