How we run determines the amount of impact forces acting on our body.
Some factors impact this more than others. Cadence and footstrike are two of the biggest.
Cadence is a measure of how many steps taken per minute.
Footstrike the angle of the foot at ground contact: heel strike vs forefoot strike.
A 2019 research paper (here) looked at the change in loading rates between increasing running cadence vs transition from a heel strike to a forefoot strike.
The results showed the change to forefoot strike was vastly superior in reducing loading rates compared with increasing cadence.
Reduction in vertical average load rates:
Forefoot strike: 49.7%
Faster cadence: 16%
That's a 3x times the reduction in loading with a transition to forefoot strike.
Reduction in vertical instantaneous load roads
Forefoot strike: 41.7%
Faster cadence: none as the change was not statistically significant
So where does the PR1 fit into this?
The PR1 is designed to help runners develop a consistent forefoot strike, and we have the data to prove it.
The graph below shows the consistency in forefoot strike in a runner using the PR1s (green line) vs a runner without.
