Abstract
The purpose of this study was to determine alactic O2 debt and lactic O2 debt in long-distance runners, and to evaluate the relationship between the property of skeletal muscle fiber and O2 debt capacity. Biopsy samples were taken from M. vastus lateralis of 13 long-distance runners, and analyzed for muscle fiber composition, capillary supply and SDH activity. O2 debt capacity was measured on a treadmill running, and calculated for alactic O2 debt and lactic O2 debt. The results of this study suggested that capillary density was a factor to regulate lactic O2 debt and/or maximal O2 debt in long-distance runners. Verf.-Referat
