A Comparison of Practical Assessment Methods to Determine Treadmill, Cycle, and Elliptical Ergometer JOURNAL/jscr/04.03/00124278-201005000-00024/OV0312_8/v/2021-02-09T093711Z/r/image-png O2peak

Abstract

This investigation compared estimated and predicted peak oxygen consumption (VO2peak) and maximal heart rate (HRmax) 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 VO2peak. Digital displays on the elliptical ergometer were used to estimate VO2peak. Two individual linear regression methods were used to predict VO2peak: 1) two steady state heart rate (HR) responses up to 85% of age-predicted HRmax, and 2) multiple steady state/non-steady state HR responses up to 85% of age-predicted HRmax. Estimated VO2peak 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 VO2peak (36.5 ± 1.0 ml · kg−1 · min−1) was lower (p < .001) than the estimated VO2peak values for the treadmill and elliptical ergometer. Elliptical ergometer VO2peak 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 VO2peak, p < .01. HRmax and estimates of VO2peak 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 VO2peak. Health-fitness professionals should use caution when utilizing submaximal elliptical ergometer digital display estimates to predict VO2peak.

Comparison of V̇o 2peak and Achievement of V̇o 2peak Criteria in Three Modes of Exercise in Female Triathletes

“…The finding that treadmill testing elicited the highest VO 2 peak is supported by others (11, 17,22). McArdle, Katch and Pechar (23) reported that the treadmill elicits a VO 2 peak 6% to 11% higher than for cycling while we observed a 13% difference between the two modes.…”

“…However, the extent that these criteria are achieved in studies is often not reported (2,5,13). Furthermore, the criteria used vary from lab to lab (22). Also, the use of HR peak is common yet many subjects do not achieve this criterion.…”

“…The following criteria were used to determine achievement of a VO 2 peak: relative plateauing of VO 2 (< 2.1ml·kg -1 ·min -1 decrease) despite an increase in workload (5,22,34); HR within 10 bpm of age estimated heart rate max (220-age) (5); blood lactate ≥ 8mmol/L (29, 34);RER > 1.1 (13,20,34); oxygen saturation ≤ 95% (25); and RPE > 17 (2,5,6). VO 2 and RER were analyzed using a flow and gas calibrated ParvoMedicsTrueOne 2400 metabolic cart (Sandy, Utah).…”

“…Effect size was calculated for each variable where a significant difference was found. The same sample size of 12 was based on previous studies comparing VO 2 peak in different modes of exercise that reported significant differences (16,22,23) and thus we judged power to be adequate. Furthermore, numerous findings here were statistically significant substantiating adequate power.…”

A meta-analysis of cardiopulmonary exercise testing in pre-pubertal healthy children produces new information

“…[56][57][58][59][60] Reports also point out that a cycle ergometer test may require an average of 10 additional minutes to achieve maximal effort than tests on treadmills, 61 because (i) subjects on the cycle ergometer have an inability to keep up with their performance; [61][62][63] (ii) a greater activation of MedicalExpress (Sao Paulo, online) 2016 February;3(1):M160102 Cardiopulmonary exercise testing in healthy children Tavares AC large amounts of muscle mass occurs during a treadmill test; 58,59,61 (iii) more discomfort in the thigh muscles occurs during the cycle ergometer test; (iv) less intensity of effort and protocol duration to maximize aerobic energy transfer is achieved on the cycle ergometer. 57,59,61 The 18-20% differences on peak VO 2 values found in this analysis were similar to the 22% difference reported elsewhere; 61 however, smaller differences have also been reported: 7%, 61 8%, 24,64 or 12% higher on a treadmill.…”
