Critical-Speed Modeling Using Familiar Performance Tests Can Accurately Predict 1500-m Rowing-Ergometer Performance...

Area of Science:

• Sports Science
• Exercise Physiology
• Biomechanics

Background:

• Assessing maximal rowing performance is crucial for training optimization.
• Existing models may not fully capture the nuances of ergometer performance.
• A reliable predictive model can enhance training strategies for rowers.

Purpose of the Study:

• To evaluate the predictive accuracy of a linear critical-speed model for maximal rowing-ergometer performance.
• To determine if this model can reliably forecast 1500-m rowing capacity.
• To validate the model against actual performance data.

Main Methods:

• Twenty highly trained rowers (5 female) completed multiple ergometer time trials (TTs).
• A linear distance-time relationship from 2000-m and 500-m TTs was used to predict 1500-m performance.
• Time-to-exhaustion (TTE) trials at predicted intensity assessed model accuracy.

Main Results:

• The critical-speed model demonstrated high accuracy, predicting 1500-m performance within 0.4% difference.
• Rowers maintained 98.6% of target power output during TTE trials.
• The model showed a near-perfect association (R² = .99) with actual performance distances.

Conclusions:

• The linear critical-speed model provides an accurate method for predicting maximal rowing performance.
• This model facilitates focused 2000-m preparation while tracking 1500-m progression.
• It offers insights into how changes in 2000-m and 500-m TT times impact predicted 1500-m performance.
