The lactate threshold (LT) and ventilatory threshold (VT) were found to differ significantly at various exercise intensities during a cycle ergometer ramp test. These findings highlight distinct physiological markers during incremental exercise.

Area of Science:

  • Exercise Physiology
  • Sports Science
  • Cardiorespiratory Fitness

Background:

  • The ventilatory threshold (VT) and lactate threshold (LT) are key indicators of exercise intensity.
  • Understanding their relationship during incremental exercise is crucial for performance assessment.

Purpose of the Study:

  • To investigate the relationship between lactate threshold (LT) and ventilatory threshold (VT).
  • To compare LT and VT during a ramp protocol in cycle ergometry.

Main Methods:

  • Thirty-nine trained male subjects underwent maximal exercise testing on a cycle ergometer.
  • A ramp protocol with 25 W.min-1 increments was used.
  • Both VT (via gas analysis) and LT (via lactate measurement) were determined and compared.

Main Results:

  • Significant differences (p < 0.05) were observed between VT and LT.
  • These differences were evident when expressed as heart rate (bpm), work rate (W), or VO2 (ml.kg-1.min-1).

Conclusions:

  • Lactate threshold and ventilatory threshold occur at distinct exercise intensities.
  • This dissociation is apparent during ramp protocol exercise on a cycle ergometer.
