Training theory and taper: validation in triathlon athletes

Area of Science:

• Exercise Physiology
• Sports Science
• Training Theory

Background:

• Optimizing athletic performance requires effective training and tapering strategies.
• Tapering, the reduction of training load before competition, is crucial for peaking.
• Various taper profiles exist, but their relative effectiveness in enhancing physical performance is debated.

Purpose of the Study:

• To predict the effectiveness of different taper formats in optimizing physical performance.
• To compare step reduction versus exponential decay tapers, and fast versus slow exponential decay tapers.
• To validate simulation predictions with experimental data from triathlon athletes.

Main Methods:

• A systems model simulated four taper profiles: step reduction, fast exponential decay, and slow exponential decay.
• Performance was predicted (p(t)) following a standardized 28-day training period.
• Field trials with triathlon athletes experimentally tested the simulated taper profiles.

Main Results:

• Simulations indicated exponential decay tapers were superior to step reduction tapers.
• Fast exponential decay tapers outperformed slow exponential decay tapers in simulations.
• Experimental results showed exponential decay tapers significantly improved cycle ergometry performance compared to step reduction tapers.

Conclusions:

• Exponential decay tapers are more effective for enhancing athletic performance than step reduction tapers.
• Faster exponential decay tapers lead to greater performance improvements than slower ones.
• The study validates the use of simulated training theories to predict optimal tapering strategies.
