The Claim

Altering the horizontal foot position (foot progression angle) during plantarflexion changes the relative activation between the medial and lateral gastrocnemius muscles, which subsequently alters the kinematic behavior and elongation profiles of the respective Achilles tendon subtendons through a neuromuscular-mechanical coupling pathway.

Source: External rotation of the foot position during plantarflexion increases non-uniform motions of the Achilles tendon.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

How it works
1 study reviewed
In plain English

How you point your feet when pushing off the ground changes how your calf muscles work together and affects how your Achilles tendon stretches. This shows that your foot angle directly influences the connection between your muscles and tendons.

See the scientific wording

The horizontal position of the foot during plantarflexion is associated with altered relative activation patterns between the medial and lateral gastrocnemius muscles, which in turn corresponds to distinct kinematic behaviors and elongation profiles across the respective subtendons of the Achilles tendon, highlighting a neuromuscular-mechanical coupling pathway influenced by foot progression angle.

What the research says

1 study
  1. Study: External rotation of the foot position during plantarflexion increases non-uniform motions of the Achilles tendon.

    Changing the angle of your foot while pushing down alters how your calf muscles fire and causes different parts of your Achilles tendon to stretch and move in unique ways.
