摘要：Paulucio D, Nogueira F, Velasques B, Ribeiro P, Pompeu F. Dayto-Day Variation of Cardiopulmonary Variables Obtained During an Incremental Cycling Test to Volitional Exhaustion. JEPonline 2015; 18(3):81-90. The purpose of this study was to analyze the reliability of measurements of oxygen consumption (VO2), carbon dioxide production (VCO2) and expired ventilation (VE) by the Vista MiniCPX® Vacumed® system. The protocol consisted of two identical, continuous efforts on an electromagnetically braked training ergometer. Sixteen trained male cyclists (32 ± 6 yrs, 69.5 ± 6.1 kg) participated in the study. There was no significant difference (P>0.05) between test and retest measurements on the device at different intensities. Measurements of test and retest of each respiratory variable were significantly correlated, with r2 = 0.95, 0.90, and 0.95 and intraclass correlation coefficient 0.98, 0.96, and 0.98 VO2, VCO2, and VE, respectively. The Vista Mini-CPX®, Vacumed® system can be considered a reliable tool to measure and assess the cardiorespiratory performance of subjects in a laboratory or research setting.
