ABSTRACT:
In order to assess the possible occurrence of acute haemolysis with prolonged exertion, serum haptoglobin levels were determined from venous blood samples collected from eight male runners immediately preceding (PreRh), immediately following (PRH1), and 6 h following (PRH2) completion of a marathon road race. The subjects' mean age, percentage of body fat, and maximum oxygen uptake (VO2 max) were about 46 years, 12.1% and 54.9 ml kg-1 min-1, respectively. The mean race finish time for the subjects was about 3 hr. 35 min. The PreRh, PRH1 and PRH2 average was about 129, 97, and 86 mg dl-1 respectively. Significant differences of minus 32.5 mg dl-1 between PreRh versus PRH1 and minus 42.5 mg dl-1 between PreRh versus PRH2 were found. The data suggest the occurrence of an acute haemolysis with performance of the marathon road race.
