Eccentric Heel Drop

The #1 Achilles-health insurance for jumpers — eccentric heel drops (Alfredson Protocol) are the gold standard for Achilles rehab; the eccentric load stimulates tendon repair. Rise on two legs, then lower slowly on one leg (3-4s); return up on two.

Eccentric Heel Drop 4-step technique breakdown: setup, execution, peak extension, and recovery for vertical jump training

Coaching cues

  • 1.Rise with two legs — lower with one (or both controlled)
  • 2.Eccentric phase 3-4s
  • 3.Straight knee targets gastrocnemius; bent knee targets soleus
  • 4.Mild discomfort OK (VAS<4/10); sharp pain means stop

Detailed training method

[Steps]1. Rise onto the toes with both feet→2. Shift weight to one leg→3. Lower slowly over 3-4s→4. Return up with both feet→5. 15 straight-knee + 15 bent-knee = 1 set [Common Errors]✗ Lowering too fast→3-4s eccentric ✗ Straight knee only→do both ✗ Sharp pain→stop; the tendon isn't ready [Progressions]Two legs→one leg→loaded→step edge→loaded single-leg [Jump-Specific]The gold standard for Achilles rehab (Alfredson Protocol); eccentric loading promotes ordered tendon collagen; the #1 Achilles-health insurance for jumpers
