There is a lack of evidence about the slow component of oxygen consumption (V.O2sc) 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 V.O2sc, 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 V.O2sc, VE VCO2−1 slope, and RPE (p > 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 (p = 0.003) and 20 min (p < 0.001). The two different exercise modalities showed similar V.O2sc and VE·VCO2−1 slope, even though the blood lactate concentrations were different.
尽管有氧舞蹈（AD）课程中氧气消耗的慢成分（V.O2sc）和通气效率（斜率VE·VCO2−1）在耐力运动中起着关键作用，但在空气消散平台（ADP）上进行有氧舞蹈课程时，关于它们的证据却很缺乏。本研究旨在通过比较两种运动模式来评估V.O2sc、通气效率和血乳酸浓度：在ADP上进行的AD课程与在第一通气阈值（VT1）的恒定负荷强度下进行的跑步机测试。在第一阶段，完成了递增式跑步机测试。在第2和第3阶段，参与者被随机分配到在ADP上进行的AD课程或在VT1强度下进行的跑步机恒定负荷测试，以确定他们的心肺反应。此外，还评估了他们的血乳酸水平和主观用力程度分级（RPE，CR-10）。在V.O2sc、VE VCO2−1斜率和RPE方面，恒定负荷跑步机测试和在ADP上进行的AD课程之间未发现显著差异（p>0.05）。在ADP上进行的AD课程中，在10分钟（p = 0.003）和20分钟（p < 0.001）时观察到的血乳酸浓度高于恒定负荷跑步机测试。尽管血乳酸浓度不同，但两种不同的运动方式显示出相似的V.O2sc和VE·VCO2−1斜率。
