Block Periodisation: Issurin's Sequential Model

Key takeaways

• Three blocks: Accumulation → Transmutation → Realisation
• Best for advanced athletes peaking for events
• Residual effects guide block length
• Concurrent training is not the same as block periodisation

Definition

Block Periodisation, formalised by Vladimir Issurin, sequences three short, focused training blocks: Accumulation (high volume, base qualities), Transmutation (sport-specific intensity) and Realisation (peaking and tapering).

Why blocks beat traditional models for advanced athletes

Concurrent training in one block dilutes adaptation. Sequencing focused blocks lets each quality develop fully while exploiting the residual training effects from prior blocks.

Residual training effects (Issurin): aerobic ≈ 30 days, max strength ≈ 30 days, anaerobic glycolytic ≈ 18 days, speed ≈ 5 days. Plan blocks so the residual lasts long enough to support the next block.
