The Claim
Partial-ROM repetitions in the dorsiflexed position during calf raises increase mean active force on the gastrocnemius by approximately 30% compared to full-ROM repetitions, resulting in a greater hypertrophic stimulus per repetition.
What the research says
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.
Performing calf raises with a partial range of motion in a dorsiflexed position produces about 30% more force in the gastrocnemius muscle per repetition than full-range movements, leading to a stronger stimulus for muscle growth.
See the scientific wording
The mechanical advantage of partial-ROM repetitions in the dorsiflexed position during calf raises may increase mean active force on the gastrocnemius by approximately 30% compared to full-ROM repetitions, potentially enhancing the hypertrophic stimulus per repetition.
When the ankle is bent upward and the calf muscle is shortened slightly during a partial repetition, the muscle fibers stretch under high tension. This stretches a protein inside the muscle called titin, which acts like a spring and sensor. When titin is pulled tight while the muscle is active, it triggers signals that tell the muscle to build more contractile units, making the muscle thicker over time.
What the research says
1 studyWhen people do calf raises and keep going with small movements after they can't do a full rep anymore, their calf muscles grow more per repetition—even if they do fewer total reps. This is because the position of the ankle makes the calf work harder in those small movements.
