The Influence of Exercise on Daily Rhythm of Serum Homocysteine in Horses

抄録

The aim of this study was to determine the daily rhythms in blood serum of homocysteine in horses. With this aim ten thoroughbred horses, five athletic (trained for 1 h, 6 days a week) and five sedentary, were used. Blood samples were collected, on each subject every 4 h for two days, by means of jugular vein. On each individual sample, it has been assessed the serum concentration of homocysteine. The results obtained during the experimental period indicated the existence of a daily rhythm of serum homocysteine in sedentary and athlete horses, and demonstrated that in horses physical exercise influences the daily rhythm of serum homocysteine.
