Following a single bout of resistance exercise, activated satellite cells (MyoD+) are located significantly closer to capillaries than quiescent satellite cells (MyoD-) in young men, suggesting that proximity to capillaries facilitates SC activation.

Resistance exercise triggers satellite cells to activate, and these activated cells tend to be closer to blood vessels, which likely helps deliver the nutrients and signals they need to repair muscle. This highlights the importance of resistance training for maintaining muscle health, especially as we age.
