Advanced strengthening

The advanced strengthening stage — heavy, specific and unilateral loading to restore full strength and robustness before power work.

Learning objectives

  • Describe the goals of the advanced strengthening stage
  • Select and dose appropriate exercises
  • Apply criteria to progress
  • Coordinate with the clinical team

Before this lesson

Why this matters

Many re-injuries occur because strength deficits persist when athletes return. Advanced strengthening closes the gap.

Goals

  • Restore strength to ≥90% of the uninjured side (limb symmetry) and to sport demands
  • Tolerate heavy and eccentric loading
  • Restore rate of force development

Methods

  • Heavy compound and unilateral lifts (split squats, RDLs, step-ups)
  • Eccentric emphasis (e.g., Nordic hamstring exercise, which roughly halves hamstring injury rates in prevention programmes [vandyk2019])
  • Isometrics at long lengths and sport-relevant angles
  • Faster concentric intent

Dosage: 3–5 × 3–8 at RIR 1–3, 2–3 times/week.

Progression criteria

Strength LSI approaching 90%, no pain with heavy loading, good movement quality under fatigue [ardern2016].

Common mistakes and misconceptions

Case study

A footballer recovering from a knee injury moves through this stage over 3–4 weeks, progressing load weekly based on next-day symptoms and strength testing, before advancing to the next stage with the physiotherapist’s agreement.

  • Exercise selection and dosage follow normal training principles, adapted to tissue tolerance.
  • Progress on criteria rather than time alone.
  • Communicate with the clinical team throughout.
