A comparison of practical assessment methods to determine treadmill, cycle and elliptical ergometer VO2peak
This investigation compared estimated and predicted peak oxygen consumption (VO 2peak ) and maximal heart rate (HR max ) among the treadmill, cycle ergometer and elliptical ergometer. Seventeen women (mean ± SE : 21.9 ± .3 yrs) exercised to exhaustion on all modalities. ACSM metabolic equations were...

Summary: | This investigation compared estimated and predicted peak oxygen consumption (VO
2peak
) and maximal heart rate (HR
max
) among the treadmill, cycle ergometer and elliptical ergometer. Seventeen women (mean ±
SE
: 21.9 ± .3 yrs) exercised to exhaustion on all modalities. ACSM metabolic equations were used to estimate VO
2peak
. Digital displays on the elliptical ergometer were used to estimate VO
2peak
. Two individual linear regression methods were used to predict VO
2peak
: 1) two steady state heart rate (HR) responses up to 85% of age-predicted HR
max
, and 2) multiple steady state/non-steady state HR responses up to 85% of age-predicted HR
max
. Estimated VO
2peak
for the treadmill (46.3 ± 1.3 ml · kg
−1
· min
−1
) and the elliptical ergometer (44.4 ± 1.0 ml · kg
−1
· min
−1
) did not differ. The cycle ergometer estimated VO
2peak
(36.5 ± 1.0 ml · kg
−1
· min
−1
) was lower (p < .001) than the estimated VO
2peak
values for the treadmill and elliptical ergometer. Elliptical ergometer VO
2peak
predicted from steady state (51.4 ± .8 ml · kg
−1
· min
−1
) and steady state/non-steady state (50.3 ± 2.0 ml · kg
−1
· min
−1
) models were higher than estimated elliptical ergometer VO
2peak
, p < .01. HR
max
and estimates of VO
2peak
were similar between the treadmill and elliptical ergometer, thus cross-modal exercise prescriptions may be generated. The use of digital display estimates of submaximal oxygen uptake for the elliptical ergometer may not be an accurate method for predicting VO
2peak
. Health-fitness professionals should use caution when utilizing submaximal elliptical ergometer digital display estimates to predict VO
2peak
