Progressive loading techniques

How to load healing and sensitive tissues progressively — isometrics, slow resistance, eccentrics, energy-storage loading and the pain-monitoring model.

Learning objectives

  • Sequence loading types from isometric to energy-storage
  • Use pain-monitoring to guide progression
  • Apply tendon-specific loading principles
  • Adjust load, range, speed and volume systematically

Before this lesson

Why this matters

Too little load leaves tissues weak; too much too soon flares symptoms. Progressive loading finds the productive middle.

Loading progression

StageExample (patellar tendon)Purpose
IsometricWall-sit or Spanish squat holds 5 × 45 sLoad with low irritability
Isotonic (slow heavy)Leg press, split squat 3–4 × 6–15, slowBuild strength and tendon capacity
Energy storageHops, jumps, boundingRestore spring-like function
Sport-specificCutting, landing, sprintingReturn to demands

Tendinopathy can be viewed as a continuum from reactive to degenerative stages, with load management central to treatment [cook2009].

Pain-monitoring model

In Achilles tendinopathy, patients who continued activity guided by a pain-monitoring model did as well as those who rested [silbernagel2007]. Principle: pain during exercise acceptable at a low level (e.g., ≤5/10 in that study), settling by the next morning, and not increasing week to week.

Variables to progress

Load → range → speed → volume → frequency → complexity. Change one at a time.

Common mistakes and misconceptions

Case study

A volleyball player with patellar tendon pain progresses from isometrics (week 1–2) to slow heavy split squats (weeks 3–8), then hops and jumps (weeks 9–12), returning to full training at week 14.

Key takeaways

  • Loading usually progresses from isometric → slow heavy (isotonic) → faster/energy-storage → sport-specific.
  • In Achilles tendinopathy, continuing activity guided by a pain-monitoring model was as effective as rest.
  • Tendinopathy is a continuum; load management is central.
  • Progress one variable at a time: load, range, speed, volume, frequency.
