      <dc:description>Background and Objectives: The prevalence of chronic diseases increases with age, and in&#xd;
octogenarian elderly, a cardiorespiratory test with gas analysis is more effective in determining the&#xd;
risk of mortality than applying the conventional risk factors. Materials and Methods: 25 untrained&#xd;
non-frail octogenarian subjects (four men) performed a submaximal test with gas analysis, which&#xd;
was stopped after the second ventilatory threshold (VT2) was reached. The variables analyzed were&#xd;
oxygen consumption at the first threshold (VO2 VT1); ventilatory class (VE/VCO2); oxygen uptake&#xd;
efficiency slope (OUES); cardiorespiratory optimal point (COP); oxygen pulse difference between&#xd;
VT2 and VT1 (diff. VO2/HR VT2-VT1). Results: the variables were classified categorically based&#xd;
on cut-off points present in the literature, where the variable with the highest percentage of altered&#xd;
cases was dif. VO2/HR VT2-VT1 at 48%; followed by VO2 VT1 at 40%, OUES at 36%, COP at&#xd;
32%, and VE/VCO2 at 24%. Chi-square analysis between the measured parameters defined that&#xd;
normal and altered variables were related to each other, except for the variable VE/VCO2 and OUES.&#xd;
Conclusions: it was found that the main altered variable was the oxygen pulse and the least altered&#xd;
variable was VCO2/VCO2; there was only a statistically significant difference in a pair of OUES vs.&#xd;
VE/VCO2 variables.</dc:description>
