Fatigue experienced by heart failure patients does not stem from reduced blood and oxygen being supplied to the muscles by the heart, as one might expect. Instead, Marks' previous research in muscles of mice with heart failure suggested the cause is calcium leak in muscle cells, which reduce the ability of a single muscle to contract repeatedly before losing force.
"We then had a hunch that the process that produces fatigue in heart failure patients also may be responsible for the fatigue felt by athletes after a marathon or extreme training," study first author Andrew Bellinger said in a prepared statement. "Our new paper shows that fatigue in both patients and athletes probably stems from the same leak."
