Abstract des Autors

Recent research into the relative contributions of the three energy systems to high intensity exercise suggests that the contribution made by the aerobic energy system has, in the past, been underestimated. However, current coaching literature still takes little note of this research, with its obvious importance for training methodology. The traditional view has been based on faulty methods of research. The latest research uses the more accurate Accumulated Oxygen Deficit method, which takes into account individual efficiency relationships in calculating the relative aerobic and anaerobic energy system contribution. Using this method, the authors conducted a treadmill experiment with small groups of sprinter and middle distance runners, simulating high intensity runs over 400, 800 and 1500 metres. The resulting data indicated that, over all these race distances, the role played by the aerobic energy system is more important than that which has long been accepted. Verf.-Referat
