The Claim

Training the gastrocnemius muscle at longer muscle lengths via initial partials may enhance muscle hypertrophy compared to training at shorter muscle lengths via past-failure partials, potentially due to greater mechanical tension on the ascending limb of the force-length curve.

Supports is higher

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

Cause and effect
1 study reviewed
In plain English

Doing calf exercises with a deeper stretch at the start might help your calf muscles grow bigger than doing them with a shorter stretch, because the stretched position could put more tension on the muscle.

What the research says

1 study

  1. Study: Resistance Training Beyond Momentary Failure: The Effects of Past‐Failure Partials Versus Initial Partials on Calf Muscle Hypertrophy Among a Resistance‐Trained Cohort

    This study found that doing calf raises starting from a stretched position (initial partials) might help your calf muscles grow a little more than doing them after you're already tired (past-failure partials), even though the difference wasn't huge. It suggests stretching your muscle at the start might be better for building muscle.
