Key result
During maximal exercise testing in pregnant women, percent of age-predicted maximal heart rate (88.0% vs ≥95%; P<0.001) and lactate (6.8 vs ≥8 mM; P=0.03) were significantly lower than standards.
Why the study?
Do standard secondary criteria for maximal aerobic capacity apply to pregnant women undergoing VO2max testing?
Population
25 pregnant women (mean age 30.0±3.6 years, gestation age 22.1±1.4 weeks, pre-pregnancy BMI 23.68±4.04 kg/m2)

Standard secondary criteria for determining maximal aerobic capacity, such as age-predicted maximal heart rate and lactate levels, may need to be adjusted lower for pregnant women.

Do standard secondary criteria for maximal aerobic capacity apply to pregnant women undergoing VO2max testing?

Hesse et al. (2018) conducted a cross-sectional in Pregnancy (n=25). Maximal cardiorespiratory fitness testing (Bruce protocol) vs. General population standards was evaluated on Secondary endpoint criteria during VO2max testing (RPE, percent of age-predicted HRmax, lactate, and RER). During maximal exercise testing in pregnant women, percent of age-predicted maximal heart rate (88.0% vs ≥95%; P<0.001) and lactate (6.8 vs ≥8 mM; P=0.03) were significantly lower than standards.
