Polarized vs Pyramidal Training

Mathematical and physiological reference for the two dominant training-intensity distribution (TID) frameworks in endurance sport, polarized (≈80/0/20) and pyramidal (≈70/20/10). Documents the three-zone classification system anchored on the lactate thresholds, the time-in-zone vs session-goal accounting conventions, the empirical evidence base from controlled crossover trials and elite-cohort observational studies, and the periodization heuristics that govern when each distribution is metabolically appropriate.
