Technique-Driven Injury Prevention

Technique-Driven Injury Prevention

1. Technique = Load Management

Strength determines how much force you can produce.
Technique determines how much force your tissues must absorb.

Most injuries happen not because the move is “too hard,” but because:

  • force direction (vector) is wrong
  • joints aren’t stacked properly
  • stabilizers are bypassed
  • hips drift too far out
  • wrist collapses
  • elbows flare
  • shoulders lose scapular support

Technique mistakes multiply local load.

2. Force Direction (Vector Control): The Heart of Injury Prevention

Climbing is applied physics:
Force must be directed along a line where joints are mechanically strong.

Correct vector

Force direction aligns with joint stacking (bones in a line).

Incorrect vector

Off-axis pull → shear load (sideways stress) on pulleys, wrist, elbow.

Examples:

  • pulling downward on slopers → skin shear + wrist collapse
  • pulling sideways on crimp → PIP/DIP torsion
  • shoulder internally rotated during sidepull → impingement
  • bicep curling instead of pulling → elbow overload

Technique = controlling vectors under varying body positions.

3. Joint Stacking: The Most Underrated Injury-Prevention Skill

Joint stacking = aligning joints so force travels through bone, not soft tissue.

Poor stacking forces tendons, pulleys, and ligaments to absorb more load.

Safe stacking examples:

The best climbers don’t “muscle through” moves — they stack joints.

4. Wrist Mechanics: Small Angles, Huge Consequences

The wrist is a mobility joint forced into stability during climbing.

Worst offender:

Wrist collapse (ulnar deviation)
→ increases finger load 30–50%
→ increases pulley stress
→ reduces friction on slopers
→ increases risk of both A2 overload and wrist tendonitis

Fix:

  • pull with wrist neutral
  • rotate hips to find better force angle
  • avoid overgripping under fatigue
  • keep elbow aligned under wrist

This instantly protects fingers.

5. Elbow Mechanics: Avoid the “Climber’s Flare”

Flared elbows = poor lever efficiency + huge strain on:

  • flexor tendons
  • medial epicondyle (golfer’s elbow)
  • rotator cuff
  • biceps tendon

Why it overloads

Elbows are hinge joints (flexion/extension), not rotation joints.
Flaring creates sideways torque → overload.

Fix:

  • elbow tracks toward midline
  • rotate hips instead of elbow
  • pull with lat engagement, not biceps
  • avoid full lock-offs in poor vectors

Elbow health is mostly technique-driven.

6. Shoulder Mechanics: Scapula First, Arm Second

Shoulders fail (impingement, strains, instability) when scapula position is lost.

Key principles:

  • scapular retraction (shoulder blade moving inward)
  • scapular depression (shoulder blade down)
  • upward rotation (arm raising safely)

Common dangerous errors:

  • catching a swing with internally rotated shoulders
  • compressions with rounded upper back
  • arm pulling before scapula engages
  • twisting under load without hip rotation

Scapula is the root of shoulder safety.

7. Hip Mechanics: Center of Mass Controls Upper Body Load

Hips determine:

  • center of mass (CoM)
  • handhold force direction
  • how much you load fingers
  • foot efficiency
  • shoulder torque

If hips drift away:

  • finger force ↑
  • elbow torque ↑
  • shoulder instability ↑
  • joint stacking fails

Good climbers lead with hips → safe vectors → low tissue load.

8. Footwork: The Hidden Injury-Prevention System

Precise footwork reduces upper-body load massively.

Common errors:

  • slipping feet → violent arm catch
  • overstepping → knee torque
  • twisting at knee instead of hip
  • loading small feet before hip is engaged

High-level climbers protect joints with foot placement.

9. Movement Efficiency Under Fatigue

Most injuries happen when technique collapses because stabilizers fatigue.

When tired, climbers:

  • overgrip
  • collapse wrist
  • twist knees
  • flare elbows
  • catch sloppily
  • lose scapular control

Solution:

  • reduce intensity before technique fails
  • more rest between attempts
  • technique-conscious warm-up
  • avoid dynamic moves when fatigued

Load management = technique management.

10. Technique-Driven Prevention Routine (5–7 min)

1. Wrist alignment trials

Pull lightly on a hold → adjust to neutral position.

2. Scapular activation

shrugs → depression → retraction → rotation.

3. Hip rotation mini-drills

internal/external rotation under light load.

4. Foot placement precision

three slow high steps each side.

5. Controlled deadpoint

focus on catching with stacked joints, not flared elbows.

This primes movement mechanics for injury-safe climbing.

When to Seek Help

  • persistent technique collapse early in session
  • inability to maintain neutral wrist
  • sharp elbow pain with flares
  • shoulder clicking + weakness
  • repeated knee pain in rotation moves
