Achilles Tendon Function in Forefoot Running

The Achilles tendon function in forefoot running is to store energy and absorb impact. This is the problem plaguing many heel strike runners –high impact landings, which suggests that the Achilles tendon isn’t working as it should to help keep impact low.

Achilles Tendon – Heel Strike vs Forefoot Strike

More Impact in Heel Strike Running

The average vertical loading rate and instantaneous vertical loading rate kick-starts many overuse injuries in heel strike runners, and according to Napier et al., these impact variables are the main risk factor for most running-related injuries.

Why Forefoot Running is Better for Your Achilles

Forefoot running however, reduces, or eliminates these load variables whereby the reduction in loading is inferred by the Achilles tendon’s capacity to absorb impact at touchdown.

  • It may be possible that the Achilles tendon is better able to absorb the impact load from initial contact over a greater period of time in forefoot running than in heel strike running (Napier et al. 2014).

These findings may also hint at a reason why some forefoot running learners experience Achilles tendon pain –because their Achilles tendon is functioning in a new way. At the same time, Achilles tendon pain will eventually vanish as soon as the body has accepted the forefoot running technique.

Overall, Napier et al. found that changing from a heel strike to a forefoot strike running style had the greatest effect on lower extremity kinematics and mechanics for the better, suggesting that adopting a forefoot strike landing is the best way to lower your risk of sustaining nagging or debilitating injuries.

BSc Neurobiology; MSc Biomechanics candidate, ultra minimalist runner & founder of RunForefoot. I was a heel striker, always injured. I was inspired by the great Tirunesh Dibaba to try forefoot running. Now, I'm injury free. This is why I launched Run Forefoot, to advocate the health & performance benefits of forefoot running and to raise awareness on the dangers of heel striking, because the world needs to know.
