Molmen et al. 2019, Block vs traditional periodisation review

Systematic review and meta-analysis. Block periodisation (BP) showed small but statistically significant favorable effects over traditional periodisation on VO2max (SMD 0.40) and Wmax (SMD 0.28), with moderate-to-large effects on endurance performance thresholds. Evidence is constrained by a small, heterogeneous literature and low methodological quality (mean PEDro score 3.7/10), so findings should be interpreted cautiously. BP is concluded to be an adequate alternative strategy with promising, if uncertain, advantages. Limited–Moderate.
