Abstract in brief

The study found that in vivo muscle specific tension increased by 17% after resistance training, but this did not affect overall muscle power output when considering muscle volume, suggesting other factors are involved.
Changes in muscle fiber type, specifically in myosin heavy chain isoforms, did not relate to the increase in specific tension, nor did changes in single-fiber properties like maximal shortening velocity or peak power.
The findings support the idea that enhanced lateral force transmission between fibers may be responsible for increased specific tension after resistance training, rather than changes in fiber composition or myofilament packing.]
