AI Model Performance & Prediction
Our machine learning models demonstrated distinct performance characteristics. The pyramidal model achieved a superior overall prediction accuracy (6.15 ± 1.12 min MAE) compared to the polarized model (7.28 ± 1.31 min MAE). This advantage was particularly pronounced for experienced runners, where pyramidal predictions showed 24.6% lower error rates, highlighting its effectiveness with advanced athletes. Feature importance analysis revealed that the pyramidal model primarily relied on training load (32.4%) and cardiovascular measures (28.5%), emphasizing aerobic development. In contrast, the polarized model showed a more balanced feature utilization, with notable emphasis on movement efficiency (22.6%) and biomechanical factors, indicating a different physiological emphasis.
The models exhibited population-specific strengths; pyramidal maintained consistent accuracy across experience levels, while polarized performed poorly for novice runners but excelled for elite athletes. This differential performance underscores the necessity for personalized training methodology selection based on individual athlete characteristics.
Optimizing Marathon Performance: Polarized vs. Pyramidal Training
Polarized training demonstrated superior marathon performance improvements (11.3 ± 3.2 min) compared to pyramidal training (8.7 ± 2.8 min), representing a 30% greater enhancement despite reduced training volume. This advantage was primarily observed in the latter half of the marathon, where polarized-trained athletes maintained pace beyond 30 km, while pyramidal counterparts experienced progressive deceleration.

Greater Marathon Performance Improvement with Polarized Training
Polarized training also resulted in more consistent pacing profiles (CV = 3.2% vs. 5.7%) and maintained 15–20% better heart rate recovery capacity throughout the marathon, particularly in later stages. This enhanced cardiac efficiency and better race management likely contributed to the sustained performance, facilitating oxygen delivery and lactate clearance during prolonged exercise. These findings emphasize the efficiency of polarized training in driving superior competitive outcomes.
Distinct Physiological Adaptations from Training Methods
Both training methodologies produced significant physiological adaptations, but with distinct patterns reflecting their intensity distributions. Polarized training led to superior VO2max improvements (+12.7% vs. +10.4%), indicating enhanced maximal aerobic capacity from high-intensity training. Conversely, pyramidal training showed greater lactate threshold velocity gains (+9.3 vs. +6.7 km/h), reflecting improved submaximal efficiency from extensive moderate-intensity volume.
| Physiological Parameter | Pyramidal Training (% Change) | Polarized Training (% Change) | Optimal Benefit |
|---|---|---|---|
| VO2max (ml/kg/min) | +10.4% | +12.7% | Polarized |
| vLT (km/h) | +9.3% | +6.7% | Pyramidal |
| Running economy at HI (%) | +4.3% | +6.9% | Polarized |
| Leg stiffness (%) | +4.7% | +8.2% | Polarized |
| Cardiac stroke volume (%) | +11.3% | +8.9% | Pyramidal |
Neuromuscular adaptations strongly favored polarized approaches, with nearly double the improvements in maximal sprint velocity and leg stiffness compared to pyramidal training. Pyramidal training produced greater cardiac stroke volume increases from volume-mediated cardiac remodeling. These findings demonstrate that intensity distribution directly influences specific physiological signatures, which in turn impact marathon performance capacity.
AI-Driven Personalized Training Prescription for Marathon Runners
Case Study: Implementing AI for Individualized Training
Our research revealed substantial heterogeneity in training methodology effectiveness, identifying four distinct responder profiles among marathon runners: polarized responders (31.5%), pyramidal responders (31.9%), dual responders (18.7%), and non-responders (17.9%). This underscores that no single training approach optimally serves all athletes, emphasizing the necessity for individualized prescription strategies.
Training experience emerged as the strongest predictor of methodology effectiveness (r=0.72, p<0.01), with novice athletes favoring pyramidal approaches and experienced athletes responding better to polarized training. Baseline VO2max also demonstrated predictive value, with higher fitness levels correlating with enhanced polarized training responses.
This AI-driven framework provides coaches and athletes with evidence-based tools for methodology selection, allowing for targeted training plans based on individual characteristics like experience level, age, baseline fitness, and running mechanics. This approach shifts from a one-size-fits-all model to a truly personalized, optimized training strategy, leading to significant performance gains and reduced training volume for the same or better outcomes.
