Key result
Calculating mean arterial pressure using a heart rate-compensated equation yielded consistently greater values than the standard equation during exercise (p<0.01).
Why the study?
Does a heart rate-compensated equation provide a different estimate of mean arterial pressure during exercise compared to the standard equation in exercising subjects?
Population
8 subjects exercising on a cycle ergometer to elicit heart rates between 100-190 beats/min

Standard MAP may underestimate during exercise; leaves open whether heart rate compensation improves accuracy before clinical or research adoption.

Does a heart rate-compensated equation provide a different estimate of mean arterial pressure during exercise compared to the standard equation in exercising subjects?
p-value: p=<0.01
The standard MAP equation underestimates mean arterial pressure during exercise because it fails to account for the increased systolic-to-diastolic period ratio at higher heart rates.
Rogers et al. (2000) reported an observational. Heart rate-compensated MAP equation (Method B) vs. Standard MAP equation (Method A) was evaluated on Mean arterial pressure (MAP) during exercise (p=<0.01). Calculating mean arterial pressure using a heart rate-compensated equation yielded consistently greater values than the standard equation during exercise (p<0.01).
