What are the best ways for runners to prevent iliotibial (IT) band syndrome?

Preventing Iliotibial Band Syndrome in Runners

Runners should prioritize hip strengthening exercises targeting the gluteal muscles combined with gait retraining to increase cadence by 5-10%, as weakness of lateral hip stabilizers is the primary causative factor in ITBS development. 1, 2

Core Prevention Strategy: Address Hip Weakness

Hip abductor strengthening is the cornerstone of ITBS prevention. Weakness or inhibition of the lateral gluteal muscles prevents proper pelvic stabilization during the running cycle and reduces eccentric control of femoral adduction. 1 When these muscles fail to fire properly throughout the support phase, compensatory patterns develop that create excessive soft tissue tightness and myofascial restrictions leading to ITB friction over the lateral femoral epicondyle. 1

Specific Strengthening Protocol

• Focus on eccentric hip strengthening exercises that emphasize triplanar motions and integrated movement patterns, particularly targeting hip abduction and external rotation. 1, 2
• Implement core and proximal strength training to optimize lower extremity biomechanics and prevent excessive hip adduction during running gait. 3
• Female runners require particular attention to hip strengthening, as excessive hip adduction during running gait is a predictor of lower extremity injuries. 3, 4

Gait Modification: Increase Cadence

Increasing step rate by 5-10% above preferred cadence reduces stride length and decreases the impingement zone stress at 30 degrees of knee flexion. 5 A runner who increased cadence from 168 to 176 steps/minute (5% increase) achieved complete pain resolution and improved running performance. 5

Gait Retraining Specifics

• Running gait analysis and retraining should address excessive stride length, strong heel strike, decreased knee flexion at initial contact, and excessive vertical displacement. 3, 4, 5
• Faster-paced running is less likely to aggravate ITBS than slower jogging, so initially recommend faster strides over slower pace. 1
• Reducing stride length or increasing cadence directly reduces tibial stress and decreases the zone of maximal ITB impingement. 3, 4

Training Modifications to Prevent ITBS

Avoid High-Risk Training Patterns

• Do not run repeatedly in the same direction on a track, as this creates asymmetric loading patterns. 1, 6
• Limit downhill running, which increases the time spent in the 30-degree knee flexion impingement zone. 1, 6
• Progress training volume using the 10% rule to avoid overwhelming tissue adaptation capacity. 3, 7
• Avoid sudden changes in distance, speed, terrain, surface, or footwear, as most ITBS cases occur after significant training modifications. 6

Surface and Terrain Considerations

• Start on level surfaces and limit hills during initial training phases. 3
• Avoid hard or uneven surfaces initially, though evidence regarding optimal running surface remains conflicting. 3, 4
• Vary terrain once adapted to base training rather than maintaining monotonous surface exposure. 3

Flexibility and Myofascial Work

Address muscle flexibility, particularly calf and hamstring tightness, as part of comprehensive prevention. 3, 7 Identifying and eliminating myofascial restrictions should precede strengthening programs. 1 However, ITB stretching alone shows limited effectiveness compared to hip strengthening—stretching-only protocols demonstrated minimal improvements in outcome measures. 2

Sex-Specific Considerations

Female runners experience higher tibial bone stresses across all running speeds and require more conservative training progression. 4, 8, 7 This applies to ITBS prevention as the biomechanical stress patterns that predispose to bone stress injuries also contribute to ITB friction syndrome. 4

Common Pitfalls to Avoid

• Do not rely solely on ITB stretching or external supports like taping without addressing underlying hip weakness—this approach shows poor outcomes. 4, 2
• Do not ignore biomechanical assessment of hip strength, running gait, and lower extremity alignment before symptoms develop. 3, 1
• Do not progress mileage beyond 20-40 miles per week without ensuring adequate hip strength, as most ITBS cases occur in runners at this volume. 6
• Do not overlook resistance training, which provides protective mechanisms by attenuating shock and reducing loads on lower extremity structures. 3

Evidence Quality Note

The hip strengthening approach is supported by both biomechanical studies demonstrating causation 1 and a randomized trial showing experimental hip strengthening consistently outperformed stretching-only and conventional exercise protocols. 2 Conservative management combining these elements produces 44% cure rates at 8 weeks and 91.7% at 6 months. 9
