Response of ventilatory and lactate thresholds to continuous and interval training

Summary
Both continuous and interval training improve lactate threshold (LT) equally. However, interval training is more effective at increasing ventilatory threshold (VT) during incremental exercise.
Area of Science:
- Exercise Physiology
- Sports Science
Background:
- Lactate threshold (LT) and ventilatory threshold (VT) are key indicators of exercise performance.
- Understanding how different training modalities affect these thresholds is crucial for optimizing training programs.
Purpose of the Study:
- To compare the effects of continuous training and interval training on changes in LT and VT.
- To evaluate the impact of varying intensities and durations of exercise on physiological adaptations.
Main Methods:
- Seventeen males participated in an 8-week training program involving cycle ergometry.
- Three groups underwent different training protocols: low-intensity continuous, high-intensity continuous, and high-intensity interval training.
- LT and VT were assessed using incremental exercise tests before and after training.
Main Results:
- All training groups showed significant increases in maximal oxygen consumption (VO2max).
- LT increased significantly and to a similar extent across all training groups.
- Interval training resulted in a significantly greater increase in VT compared to continuous training.
Conclusions:
- Continuous and interval training are equally effective in enhancing LT.
- High-intensity interval training is superior to continuous training for improving VT.
- Training intensity and modality play a significant role in specific physiological adaptations.
