The Claim
In young adults, eight weeks of resistance training following two weeks of limb disuse leads to an increase in capillary number within type II muscle fibers and an increase in fiber cross-sectional area, with capillary number rising from baseline to post-training and fiber size increasing by 25% from mid-point to post-training and by 20% from baseline to post-training.
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 young adults stop using a limb for two weeks and then do eight weeks of strength training, their muscle fibers get bigger and gain more blood supply.

Eight weeks of resistance training following 2 weeks of limb disuse increases type II muscle fiber capillary number and cross-sectional area in young adults, with capillary number rising from baseline to post-training and fiber size increasing by 25% from mid-point to post-training and 20% from baseline to post-training.
What the research says
1 studyThe study found that after two weeks of not using a limb and then doing eight weeks of strength training, people grew more blood vessels and bigger muscle fibers, just like the claim says.
