How to make running safer is easier than you think. The best solution to all your running-related problems is forefoot running. Why does running foot strike matter so much though?

Foot strike in running determines impact  –the magnitude of the ground reaction force– a force confirmed as one of the underlying causes of most running injuries. Therefore, the fundamental ingredient for injury prevention in running is to reduce this force by landing on your forefoot while you run.

4 Reasons Forefoot Running is Safer than Heel Striking

4 Reasons Why Forefoot Running is Safer Than Heel Striking

Forefoot running is safer than heel striking because it significantly reduces the vertical ground reaction force impact peak (also known as the heel strike transient). This impact peak is a variable of the ground reaction force that occurs only if the first part of the foot to strike the ground is the heel (i.e. heel strike) during running.

A study by Gruber et al., took it one step further and compared the impact shock frequency components and attenuation in heel strike and forefoot running, and unsurprisingly, found that forefoot running was safer than heel strike running on many levels:

1. Less Peak Positive Tibial Acceleration

Forefoot running reduces tibial acceleration by reducing heel vertical velocity, stride length, knee extension at touchdown and leg angle [1, 2], suggesting that forefoot running may prevent shin splints and shin fractures.

2. Less High & Low Peak Power Frequency Range of the Tibia

Forefoot running reduces the high peak power frequency range on the tibia thereby lowering the vertical ground reaction force and rapid deceleration of the foot and leg following initial ground contact [2-4]. Kinematically, this is how forefoot running reduces the braking effect that is produced in heel strike running.

3. Better Joint Geometry Characteristics

Is Forefoot Running Safer?
Better joint geometry of the ankle-foot complex in forefoot running reduced loading on the tibia

Joint geometry at touchdown can create conditions that affect impact during running.

In forefoot running, the foot-ankle complex is plantarflexed, allowing a safer, more cushy foot-ground collision which in turn, reduces peak tibial acceleration magnitude [2].

Also, ankle plantarflexion at touchdown in forefoot running allows for better ankle compliance which may help lower tibial deceleration rates after ground contact.

4. Less Shock for Body to Absorb

Forefoot running is associated with less shock attenuation frequency because as mentioned above, foot-ground collision is lighter [5-7]. Therefore, the body is exposed to less shock in forefoot running which spares the body of investing extra energy into shock attenuation.

The Take Home Message

Heel strike running harbors impact parameters linked to most running injuries that are classified as repetitive stress injuries.

Over time, the high impact nature of heel strike running exceeds the capacity and resiliency of tissues and mechanisms of the body responsible for attenuating shock.

And, it is unlikely that cushioned running shoes absorb impact because not only do they encourage heel strike, but running injury rates remain steadily high.

Forefoot Running is Better than Heel Striking Running
In the realm of statistics, runners who are forefoot strikers have fewer injuries than those who heel strike. To enhance the resiliency on the body’s shock attenuation mechanisms, the simple solution is to change footfall pattern to that of a forefoot running style.
