The Claim
Bent-leg calf raise exercises produce significantly greater increases in soleus muscle thickness compared to straight-leg calf raise exercises in young women performing exercises to muscular failure.
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.
When young women do calf raise exercises until they can't do any more, doing them with bent legs makes the calf muscle grow about twice as much as doing them with straight legs.
See the scientific wording
In young women performing calf raise exercises to muscular failure, bent-leg calf raises produce significantly greater increases in soleus (SOL) muscle thickness compared to straight-leg calf raises (+15.4% vs +7.7%, p<0.001)
What the research says
1 studyThe study tested exactly what the claim says - it compared bent-leg to straight-leg calf raises in young women doing exercises until their muscles gave out. The results showed bent-leg raises increased soleus muscle thickness by 15.4% while straight-leg raises only increased it by 7.7%, exactly matching the claim.
