Episode notes
Footstrike Distribution And Load Shifts
- About 80–85% of runners rearfoot strike; very few are natural forefoot strikers.
- Switching from rearfoot to forefoot shifts large loads to the Achilles/plantarflexors and can dramatically raise their cumulative load.
Cushioning, Strike, And Load Redistribution
- Less shoe cushioning often leads runners to adopt flatter (mid/forefoot) strikes and shorter ground contact times.
- Remember this reduces impulse overall but concentrates more load on plantarflexors and calf musculature.
Key Factors In Patellofemoral Pain
- Patellofemoral pain (under the kneecap) is common and recurs often, especially in females.
- Quadriceps weakness and excessive knee collapse (dynamic valgus) are key biomechanical risk factors.
