Abstract
There is a lack of evidence about the slow component of oxygen consumption ( . VO2sc ) and ventilatory ef ciency (slope VE VCO 2 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 . VO2sc , ventilatory ef ciency, and blood lactate concentration by comparing two exercise modes: AD session on an ADP versus treadmill test at a constant-load intensity of the rst ventilatory threshold (VT1). In the rst 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 signi cant differences were found between the constant-load treadmill test and AD session on an ADP with respect to . VO2sc , VE VCO 2 1slope, 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 . VO2sc and VE VCO 2 1slope, even though the blood lactate concentrations were different.
