Abstract
CD2F1 mice were inoculated with C26 adenocarcinoma cells, followed by assessment of ex vivo muscular function. Muscles from tumor‐bearing mice had a significantly lower force output during a single maximal contraction and during repeated contractions than control muscles. The relative force output, however, did not differ when corrected for muscle mass. Thus, cachexia significantly reduces absolute skeletal muscle function, but muscle “quality” appears unaltered.
