Summary
This study found that both critical velocity (CV) and mean velocity during 30 minutes of continuous effort (V30min) accurately estimate anaerobic threshold in stand-up paddle (SUP). V30min is recommended for prescribing SUP training intensities.
Area of Science:
- Sports Science
- Exercise Physiology
- Biophysics
Background:
- Determining anaerobic threshold (AT) is crucial for optimizing endurance training.
- Traditional AT assessment methods can be time-consuming and demanding.
- Stand-up paddle (SUP) requires specific protocols for physiological assessment.
Purpose of the Study:
- To validate alternative methods for estimating anaerobic threshold (AT) in stand-up paddle (SUP).
- To compare the validity of critical velocity (CV) and mean velocity during 30 minutes of continuous effort (V30min) against the onset of blood lactate accumulation (OBLA).
Main Methods:
- Eight athletes performed maximal efforts (400m, 500m, 800m) for CV calculation.
- Lactate levels were measured at 85%, 90%, and 100% of 500m maximal effort to determine OBLA.
- A 30-minute continuous effort was conducted to determine V30min.
Main Results:
- No significant differences were found between OBLA and the alternative methods (CV and V30min).
- Strong correlations were observed between OBLA and both CV (r=0.84) and V30min (r=0.94).
- V30min showed higher limits of agreement (±0.08 m·s-1) compared to CV (±0.23 m·s-1).
Conclusions:
- Both CV and V30min are valid methods for estimating OBLA in SUP athletes.
- The V30min method is recommended for prescribing training intensities in SUP due to its specificity and high agreement with OBLA.
