Silva Oliveira, Boppre & Fonseca 2024, Training intensity distribution meta-analysis

17 studies, 437 participants: POL was superior to other distributions for VO2peak (SMD 0.24; 95% CI 0.01, 0.48; p = 0.040), though the effect was limited to interventions shorter than 12 weeks and highly trained athletes. No evidence of superiority for time-trial, time to exhaustion, or speed at threshold. Strong.
