Building Muscle: Cells on the Move
Read on to learn exactly how fitness classes leave you with more muscle or better tone.

upper-body muscles might have hindered early humans who had to chase
their prey across the plains, but it could help those who often had to
climb trees to adjust their satellite dishes. That’s why the body builds
muscle according mostly to use: do enough curls, and the biceps expand.
As anyone who has experienced post-workout soreness could intuit, those
curls are actually a form of controlled damage, making thousands of
miniscule tears to the muscle tissue that beckon autoimmune cells to
show up alongside testosterone and other hormones. The white blood cells
help switch on satellite cells, which are similar to stem cells. Before
they’re activated, satellite cells aren’t doing much—instead, they lie
dormant around muscle fibers until they’re called into action to repair
torn tissue.
This isn’t the only kind of cellular transformation
at work in growing muscles. Long muscle cells, which contain several
nuclei, can also begin to change type after a workout. Certain kinds of
muscle fibers are equipped to handle brief bursts of effort but will
quickly become tired if asked to do more intense work. These are the
first to disappear as someone starts an exercise routine, as they’re
converted into fibers with more endurance. This principle is so dramatic
that a sports scientist can generally tell whether someone is a
professional athlete or a professional mattress model by examining a
minute sample of muscle tissue.
