The purpose of this study is to analyze the differences in cardiorespiratory performance during the PACER test using the Classic Beep Method (CBM) in comparison with a technology designed to visually and aurally set the running pace, the PACETECH. Participants (n=10; age: 20.6±1.2 years) were assessed on the PACER test at two moments separated by one week. In the first moment they performed the test with the PACETECH, and in the second moment they performed the test with the CMB. The results showed that the average value of shuttles with PACETECH was 71.0±24.4 while with CMB it was 62.9±22.4. Regarding the estimation of the maximum oxygen uptake (VO2max), the mean value with PACETECH was 44.1±9.4 ml/kg/min while with CMB was 44.7±9.0. The differences between conditions were not significant in the estimation of VO2max (Z=-1.478; p=0.139; %Dif.= 1.2%), and between completed shuttles (Z=-1.602; p=0.109; %Dif.= -12.95). The lack of differences between conditions represents the potential of PACETECH as a complement to the beep signal in determining the running pace. This study should be replicated with samples of younger ages in order to prove the usefulness of PACETECH during the PACER test.
