Abstract: The general behavior of cardiorespiratory responses during incremental exercise are well established. However, these responses can be influenced by factors such as age, gender, physical performance, genetic factors and others. The purpose of this study was to verify the peak oxygen uptake (%Oi peak), the peak workload and the venn'latory anaerobic threshold (AT) in two groups of brazilian sedentary men: Gl (n=15) x=2lyr and 02 (n=10) 55=53 yr. Dynamic exercise tests were applied in a cicloergometer (Quinton, in sitting position) using a continuous protocol up to physical exhaustion, with direct measuremment of the VOi (MMCSensormedics). The results (medians) for the groups were: 02 peak (ml/Kg/min)= 38(G1) and 27.3(02) (p<0.05); WL peak(Watts)= 212(01) and 163(02) (p<0.05); AT(%VO2 peak)= 64%(G1) and 67.2%(G2). These results have shown that during incremental exercises most of the studied parameters were higher in the younger group, with the exception of AT (%O2 peak) which showed differences not statiscally significant.
