Differences in the ventilatory thresholds in treadmill according to training status in 971 males and 301 females: a cross-sectional study

To analyze the influence of training status on the percentage of maximum oxygen consumption, heart rate and velocity (%VO , %HR and %V ) at which ventilatory threshold 1 and ventilatory threshold 2 occur (VT1 and VT2, respectively), in males and females separately considering age, during a ramp incremental treadmill test. 791 males (36.8 ± 9.9 years) and 301 females (33.9 ± 11.0 years) performed a ramp incremental exercise test until fatigue where VT1 and VT2 were determined. Participants were classified as low, medium or high training status combining the oxygen consumption at VT1, VT2 and VO by clustering analysis. VO is poorly correlated with the %VO , %HR and %V at which VT1 and VT2 occur (r
