The Claim
In young adults, a 2-week period of limb disuse followed by 8 weeks of resistance training is associated with changes in skeletal muscle angiogenesis-related protein markers, including increased levels of vascular endothelial growth factor (VEGF), VEGF receptor-2 (VEGFR2), thrombospondin-1 (TSP-1), TIMP1, and pan eNOS, indicating a dynamic angiogenic response during muscle atrophy and recovery, independent of prior resistance training history.
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 adults stop using a limb for 2 weeks and then do 8 weeks of strength training, their muscles show signs of rebuilding blood vessels—even if they’ve never trained before.

What the research says
1 studyThe study looked at how leg muscle blood vessel markers change after 2 weeks of not using the leg and then 8 weeks of weight training. It found that these markers increased during recovery, just like the claim says, whether or not people had trained before.
