The Claim
Exercises that position biarticulate muscles at longer lengths (via joint angle manipulation) produce greater hypertrophy in those biarticulate muscle heads compared to exercises that place them at shorter lengths.
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 a muscle crosses two joints, stretching it at one joint makes it longer overall, which can make it grow more when you exercise it.

What the research says
2 studiesThis study found that when muscles are stretched more during exercise (like bending your knee more), they work harder — and working harder like this is how muscles grow bigger over time. So even though it didn’t measure muscle growth directly, it shows the right conditions for it.
