There is a lack of evidence about the slow component of oxygen consumption (<inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><mover><mi mathvariant="normal">V</mi><mo>.</mo></mover><msub><mi mathvariant="normal">O</mi><mrow><mn>2</mn><mi>sc</mi></mrow></msub></mrow></semantics></math></inline-formula>) and ventilatory efficiency (slope VE·VCO₂⁻¹) during an aerobic dance (AD) session on an air dissipation platform (ADP) despite the key role played in endurance exercises. This research was designed to assess <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><mover><mi mathvariant="normal">V</mi><mo>.</mo></mover><msub><mi mathvariant="normal">O</mi><mrow><mn>2</mn><mi>sc</mi></mrow></msub></mrow></semantics></math></inline-formula>, ventilatory efficiency, and blood lactate concentration by comparing two exercise modes: AD session on an ADP versus treadmill test at a constant-load intensity of the first ventilatory threshold (VT1). In the first session, an incremental treadmill test was completed. In sessions 2 and 3, the participants were randomly assigned to the AD session on an ADP or to a treadmill constant-load test at VT1 intensity to determine their cardioventilatory responses. In addition, their blood lactate levels and ratings of perceived exertion (RPE, CR-10) were evaluated. No significant differences were found between the constant-load treadmill test and AD session on an ADP with respect to <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><mover><mi mathvariant="normal">V</mi><mo>.</mo></mover><msub><mi mathvariant="normal">O</mi><mrow><mn>2</mn><mi>sc</mi></mrow></msub></mrow></semantics></math></inline-formula>, VE VCO₂⁻¹ slope, and RPE (<i>p</i> > 0.05). Higher blood lactate concentrations were observed in an AD session on an ADP than in a constant-load treadmill test at 10 min (<i>p</i> = 0.003) and 20 min (<i>p</i> < 0.001). The two different exercise modalities showed similar <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><mover><mi mathvariant="normal">V</mi><mo>.</mo></mover><msub><mi mathvariant="normal">O</mi><mrow><mn>2</mn><mi>sc</mi></mrow></msub></mrow></semantics></math></inline-formula> and VE·VCO₂⁻¹ slope, even though the blood lactate concentrations were different.
