Satellite cell content
upin humans1
Blood-flow-restricted exercise increases satellite cell content in humans (healthy controls, BFRE-trained versus untrained vastus lateralis) (1.53 ± 0.30-fold difference).
“In controls, satellite cell content and MuRF1 transcript expression were significantly higher (1.53 ± 0.30- and 1.34 ± 0.31-fold difference, respectively)”
