This study sets up to investigate the importance of physiological traits in relation to metabolism in the development of speed endurance among runners at middle-distances. It aims at determining the level of physiological traits which are associated with metabolism among runners; in addition of developing the required physical attributes especially speed endurance. Accordingly, the researchers have administered two main physiological tests: The River index test and the Shannon flash back heart curve test to a sample of 15 runners from the athletics games club of Blida (Algeria). Their age range varies between 17 and 18 years.
