• The purpose of this study was to analyze the reliability of measurements of oxygen consumption (V[O.sub.2]), carbon dioxide production (VC[O.sub.2]) and expired ventilation ([V.sub.E]) by the Vista MiniCPX[R] Vacumed[R] system. The protocol consisted of two identical, continuous efforts on an electromagnetically braked training ergometer. Sixteen trained male cyclists (32 [+ or -] 6 yrs, 69.5 [+ or -] 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 [r.sup.2] = 0.95, 0.90, and 0.95 and intraclass correlation coefficient 0.98, 0.96, and 0.98 V[O.sub.2], VC[O.sub.2], and [V.sub.E], respectively. The Vista Mini-CPX[R], Vacumed[R] system can be considered a reliable tool to measure and assess the cardiorespiratory performance of subjects in a laboratory or research setting.
