The Claim
Externally rotated foot positioning during heel-raise exercises produces significantly higher electromyographic activation in the medial gastrocnemius relative to the lateral gastrocnemius during both concentric and eccentric muscle contractions, demonstrating that foot pronation mechanics directly dictate calf muscle recruitment patterns in resistance training.
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.
Turning your feet outward while doing calf raises makes the inner part of your calf muscle work harder than the outer part. This shows that how you position your feet changes exactly which calf muscles get targeted during the exercise.
See the scientific wording
Performing heel-raise exercises with an externally rotated foot position elicits significantly greater electromyographic activation in the medial gastrocnemius compared to the lateral gastrocnemius during both the concentric and eccentric phases of the movement, indicating that altering foot pronation mechanics directly influences specific calf muscle recruitment patterns during resistance training protocols and provides objective evidence for exercise selection.
What the research says
1 studyThe study confirms that turning your feet outward while doing calf raises specifically targets the inner calf muscle more than the outer one during both lifting and lowering phases. This gives clear proof that changing foot angle changes which calf muscles work hardest.
