The Claim
Performing loaded static stretches between resistance training sets increases soleus muscle hypertrophy and strength relative to passive rest periods.
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.
If you swap out your usual rest breaks between weightlifting sets for stretches that include light weights, this claim says it will help your calf muscle grow bigger and get stronger. It suggests that active stretching beats just sitting still when trying to build calf size and power.

Incorporating loaded static stretches between resistance training sets enhances soleus hypertrophy and strength compared to passive rest periods.
What the research says
2 studiesStudy: Loaded inter-set stretch may selectively enhance muscular adaptations of the plantar flexors
Adding a brief stretch between weightlifting sets helped grow the soleus calf muscle and slightly improved strength compared to just resting. This suggests that stretching between sets is a useful technique for building calf size and power.
Study: Loaded inter-set stretch may selectively enhance muscular adaptations of the plantar flexors
Adding a brief stretch between exercise sets helped grow the calf's deeper muscle and made it stronger compared to just resting.
