Middle aged athletes in Japan were studied to evaluate changes in their hematological indices. Ninety-two male and twelve female athletes (average age, male: 53.3 years, female 43.8 years) were examined for blood characteristics at the world veterans championship athletic meeting. Sixty-five male and nine female marathon runners all showed elevation of creatine kinase (CK) and HDL-Cholesterol before competition (CK, male: 220.3IU/L, female: 135.3IU/L, HDL-Cholesterol, male: 80.7mg/dl, female: 83.5mg/dl). Twenty-three of twenty-five male marathon runners showed a significant increase of CK (580IU/L), LDH (626.4IU/L), WBC (10940.9/mm) and GOT (38.5IU/L) after the competition. In conclusion, it was shown that long distance training in middle aged athletes caused elevation of HDL-Cholesterol and CK.
