The Claim
In previously untrained young men, 10 weeks of resistance training is associated with proportional expansion of myofibril area relative to fiber cross-sectional area increases in both type I and type II muscle fibers, indicating conventional hypertrophy rather than sarcoplasmic hypertrophy or myofibril packing as the primary adaptation mechanism.
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 guys who haven't lifted weights before do strength training for 10 weeks, their muscle fibers grow in a way that makes them stronger, not just bigger with extra fluid. It's like building real muscle instead of just puffing it up.

What the research says
1 studyThe study shows that when untrained young men did 10 weeks of weight training, their muscle fibers grew mainly by adding more contractile parts, not just fluid, which matches the claim.
