Summary
Determining the anaerobic threshold (AT) in athletes can be done using noninvasive ventilatory methods or field tests. These two methods showed a significant correlation for both runners and cyclists.
Area of Science:
- Sports Medicine
- Exercise Physiology
- Cardiovascular Physiology
Background:
- The anaerobic threshold (AT) is a critical physiological marker for endurance performance.
- Accurate and noninvasive methods for AT determination are essential for training prescription in athletes.
Purpose of the Study:
- To compare the validity of two noninvasive procedures for determining the anaerobic threshold (AT).
- To assess the correlation between ventilatory-based AT measurements and field test-derived AT values in endurance athletes.
Main Methods:
- Noninvasive AT determination using ventilatory methods on a treadmill (runners) and cycloergometer (cyclists).
- Comparison with AT values obtained from a field test.
- Study included 15 long-distance runners and 6 cyclists.
Main Results:
- A significant positive correlation was found between AT values obtained by ventilatory methods and the field test.
- This suggests that the field test is a reliable noninvasive method for assessing AT.
Conclusions:
- Noninvasive ventilatory methods and field tests provide comparable anaerobic threshold (AT) values in endurance athletes.
- Field testing offers a practical and valid alternative for AT assessment in runners and cyclists.
