Summary

Motor learning research consistently shows a contextual interference effect: practice arrangements that make training harder and messier produce better long-term retention and transfer to competition.

Blocked vs random

  • Blocked practice (50 crosscourt forehands) improves in-session performance quickly, then fades.
  • Random practice (rotating shot, target and depth) looks worse in session and retains far better.

How we structure a session

  • 15 min technical block with clear constraint.
  • 30 min randomised pattern play with scoring.
  • 20 min match-condition points with pressure rules.

Practical takeaway

If training feels comfortable and repetitive, it is probably not transferring. Add decisions.
