The purpose of this study was to evaluate the relationship between mitochondrial Ca2+ concentration and the respiratory control index (RCI; state III/state IV) in isolated mitochondria before and after exhaustive exercise at 75% of maximal O2 consumption. Muscle biopsies of 100-150 mg from 12 moderately trained men were sampled at rest, immediately after exercise, and 30 or 60 min after exercise. The mitochondrial Ca2+ content after exhaustive exercise was significantly higher than the… CONTINUE READING
