The Claim

After the walk-run transition, the tibialis anterior muscle exhibits reduced activity and reduced mean power frequency, indicating a shift toward slower motor unit recruitment.

Source: Why do we transition from walking to running? Energy cost and lower leg muscle activity before and after gait transition under body weight support

How it works
1 study reviewed
In plain English

During the transition from walking to running, the tibialis anterior muscle becomes less active and its electrical signals shift to slower firing patterns.

See the scientific wording

The tibialis anterior muscle exhibits reduced activity and mean power frequency after the walk-run transition, suggesting a shift toward slower motor unit recruitment that may help reduce fatigue during running, despite its minor role in propulsion.

Why this might work

When walking gets too fast, the shin muscle works harder and uses fast-tiring fibers. When the body switches to running, the way the leg moves reduces the strain on this muscle, so it stops using the fast-tiring fibers and starts using slower, more fatigue-resistant fibers instead. This keeps the muscle from getting tired too quickly during running.

  1. Study: Why do we transition from walking to running? Energy cost and lower leg muscle activity before and after gait transition under body weight support

    When people switch from walking to running, their shin muscle (tibialis anterior) slows down its firing pattern, using more tiredness-resistant fibers — likely to save energy and avoid getting sore too soon, even though it doesn’t help much with pushing forward.
