“…Since maximum heart rates were similar on the treadmill and cycle, O2 pulse was also higher during treadmill er gometry (p<0.01). These observations are consistent with previous data [14][15][16] and presumably reflect the usual exercise pat terns of our normal subjects. In addition, however, our results indicate that differ ences between VO2 on the treadmill and cycle ergometer increased as the individ ual subject's level of VO2 increased, i.e.…”

It has recently been reported that blood and muscle lactate increased exponentially during incremental exercise, casting some doubt upon the concept of ‘anaerobic threshold’. To gain further insight into this controversy, we examined the relationships between minute ventilation (V_E), time and oxygen uptake (VO₂) in normal subjects during incremental exercise. During exercise, the relationship of V_E to either time of exercise or to VO₂ appeared curvilinear; V_E was reliably described as an exponential function (y = ax^b + c) of both time of exercise (r² = 0.96) and VO₂ (r² = 0.92). We also compared variables from 30-second incremental tests with variables obtained from quasi-steady-state incremental tests using cycle and treadmill ergometry. With the exception of heart rate, variables measured at maximum exercise were similar during short-duration and quasi-steady-state incremental tests. These data support the ideas that: (1) there is no abrupt change in metabolism and oxygen availability during progressive exercise, and (2) results of rapid incremental and quasi-steady-state exercise tests are generally comparable in normal individuals.

“…[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.…”

The objective of the paper was to analyze cardiopulmonary data and functional capacity in healthy children who have undergone ergospirometry. A systematic meta-analysis review of ergospirometry in children was performed based on reports indexed in PubMed, Bireme, and Embase. End points were age, sex, body mass index, maturation evaluation, the type of ergometer used for ergospirometry, and cardiopulmonary related values (peak heart rate and peak oxygen consumption [VO 2 ]). Twenty articles were selected, which included 3,808 children, averaging 9.1years of age. A treadmill was used in 55% of the trials, and a cycle ergometer in the other 45% studies included in this analysis. The following statistically significant results were found: on subgroup analysis, peak VO 2 values in boys on the treadmill was 20% higher than peak VO 2 values in girls on the cycle ergometer; peak VO 2 values in boys on the treadmill were 18% greater than that for girls on the same ergometer. BMI was inversely correlated with peak VO 2 in the total analysis, and in female subjects on cycle ergometers. Peak heart rate during the ergospirometrical test was 5.6 BPM higher than the estimated 95% maximum heart rate. Most of the ergospirometrical parameters had not been reported in the original trials analyzed here. We conclude that peak VO 2 value for pre-pubertal children are circa 18% higher in boys vs. girls and overall higher in treadmill vs. cycle ergometers.

“…and disease have reported that the V O 2 at the anaerobic (AT) or ventilatory (T vent ) threshold is significantly higher when incremental exercise testing is performed on a treadmill than on a cycle ergometer [9,12,15,18,19,23,25,30,32,43]. These Relationship between exercise-induced decreases (Δ) in plasma bicarbonate (HCO 3 -) concentrations and increases in the ventilation above and beyond that needed to support any given increment in oxygen uptake (i.e., excess ventilation) during submaximal and maximal exercise on a cycle ergometer and treadmill.…”

In a randomized cross-over study of 15 healthy men aged 20–30 years, we compared physiological and perceptual responses during treadmill and cycle exercise test protocols matched for increments in work rate — the source of increased locomotor muscle metabolic and contractile demands. The rates of O2 consumption and CO2 production were higher at the peak of treadmill versus cycle testing (p ≤ 0.05). Nevertheless, work rate, minute ventilation, tidal volume (VT), breathing frequency (fR), inspiratory capacity (IC), inspiratory reserve volume (IRV), tidal esophageal (Pes,tidal) and transdiaphragmatic pressure swings (Pdi,tidal), peak expiratory gastric pressures (Pga,peak), the root mean square of the diaphragm electromyogram (EMGdi,rms) expressed as a percentage of maximum EMGdi,rms (EMGdi,rms%max), and dyspnea ratings were similar at the peak of treadmill versus cycle testing (p > 0.05). Ratings of leg discomfort were higher at the peak of cycle versus treadmill exercise (p ≤ 0.05), even though peak O2 consumption was lower during cycling. Oxygen consumption, CO2 production, minute ventilation, fR, Pes,tidal, Pdi,tidal and Pga,peak were higher (p ≤ 0.05), while VT, IC, IRV, EMGdi,rms%max, and ratings of dyspnea and leg discomfort were similar (p > 0.05) at all or most submaximal work rates during treadmill versus cycle exercise. Our findings highlight important differences (and similarities) in physiological and perceptual responses at maximal and submaximal work rates during incremental treadmill and cycle exercise testing protocols. The lack of effect of exercise test modality on peak work rate advocates for the use of this readily available parameter to optimize training intensity determination, regardless of exercise training mode.
