The Claim
Inter-set stretching during resistance training selectively enhances hypertrophy in type I (slow-twitch) muscle fibers compared to type II (fast-twitch) muscle fibers, potentially due to increased responsiveness of mechanosensitive signaling pathways in slow-twitch muscle populations.
What the research says
Not yet evaluated
We are still looking at what the research says.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Taking a brief stretch between sets of weightlifting might build slow-twitch muscles more than fast-twitch ones. This could happen because slow-twitch muscles are more sensitive to the physical stretching signals that tell them to grow.
See the scientific wording
Inter-set stretch may selectively enhance hypertrophy in type I (slow-twitch) muscle fibers compared to type II (fast-twitch) fibers, as observed in studies showing greater soleus muscle thickness increases than gastrocnemius increases following stretch-integrated resistance training. This fiber-type specificity suggests mechanosensitive pathways may be more responsive in slow-twitch muscle populations.
