Abstract:This study assesses the impact of three volumetric gas flow measurement methods—turbine (fT); pneumotachograph (fP), and Venturi (fV)—on predictive accuracy and precision of expired gas analysis indirect calorimetry (EGAIC) across varying exercise intensities. Six males (Age: 38 ± 8 year; Height: 178.8 ± 4.2 cm; : 42 ± 2.8 mL O2 kg−1 min−1) and 14 females (Age = 44.6 ± 9.6 year; Height = 164.6 ± 6.9 cm; = 45 ± 8.6 mL O2 kg−1 min−1) were recruited. Participants completed physical exertion on a stationary cycle… Show more
