The Claim
Internal foot rotation during plantar flexion exercises increases electromyographic activation of the lateral head of the gastrocnemius muscle compared to neutral or external foot positioning in physically active young men, suggesting a targeted approach for asymmetric calf muscle development.
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 inward while doing calf raises targets the outer part of your calf muscle more than keeping them straight or turned out. This means you can use this specific foot position to deliberately work one side of your calf if you want to build it unevenly.
See the scientific wording
Performing plantar flexion exercises with feet positioned inwards is associated with greater electromyographic activation of the lateral head of the gastrocnemius muscle compared to feet positioned outwards or forwards in physically active young men, demonstrating that internal foot rotation preferentially recruits the outer calf muscle compartment during this movement, offering a practical method for asymmetric calf development.
What the research says
1 studyPointing your toes inward while doing calf raises specifically targets the outer part of your calf muscle more than pointing them straight or outward. This means you can use this technique to work one side of your calf more than the other if needed.
