When people did strength training with their muscles stretched out, their muscle fibers got longer—and the more they got longer, the quicker they got tired. This matches exactly what the claim said.

Gold Standard Evidence Needed

According to GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this specific claim, ordered from strongest to weakest evidence.

Similar Assertions

When people train with their muscles bunched up, the more their muscle fibers angle upward, the longer they can keep pushing hard before getting tired.

Doing 8 weeks of strength training with your muscle either stretched or bunched up doesn’t make you much better at resisting fatigue — the improvement is very small and not clearly real.

Doing strength exercises with your muscle stretched out for 8 weeks can make the muscle fibers longer, but doing them with your muscle bunched up doesn’t change their length.

After doing leg exercises with your knee bent all the way back, your muscles are weaker not just at that angle—but even more so when you try to use them with your knee only slightly bent, as if your muscle fibers got stretched out and lost their normal power.

Some studies say full-range lifting makes muscle fibers longer, but the tools used to measure this might be inaccurate, so we can’t be sure it’s really happening.
