The Claim
Performing seated calf-raise exercises at short muscle lengths (70% 1RM, twice weekly) for 12 weeks produces negligible or statistically non-significant hypertrophy in the lateral and medial gastrocnemius muscles, with volume increases of only 1.7% and 0.6%, respectively.
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.
Doing seated calf raises while keeping your knees bent (short muscle length) twice a week for three months won't really build up your calf muscles. Research indicates this specific method only leads to tiny, unnoticeable muscle growth.
See the scientific wording
Seated calf-raise training performed at short muscle lengths results in negligible or statistically non-significant hypertrophy in the gastrocnemius muscles over a 12-week period. Despite training at 70% of one-repetition maximum for two sessions per week, the lateral and medial gastrocnemius showed only 1.7% and 0.6% volume increases, respectively, failing to reach statistical significance.
What the research says
1 studyStudy: Triceps surae muscle hypertrophy is greater after standing versus seated calf-raise training
The study confirms that doing calf raises while sitting barely builds muscle size in the main calf muscles over 12 weeks. Standing up while doing them is much better for growth.
