| Outline of Final Research Achievements |
We examined the onset mechanism of sports anemia in response to exercise induced hemolysis and iron deficiency and searched for effective nutrients for exercise induced hemolysis. We performed acute and chronic high intensity exercise tolerance tests of rats under various conditions and compared physiological and iron metabolic fluctuations. As a result, it was shown that exercise induced hemolysis model rats can be prepared. Because intake of uronic acid bonded xylooligosaccharide, which has been shown to be useful for prevention and improvement of iron deficiency anemia, has led to suppression of hemolysis inducing factors such as lactic acid production and muscle damage in exercise induced hemolytic model rats, we suggested that uronic acid bonded xylooligosaccharide is one of nutrient components contributing to the prevention of sports anemia.
