In running, some factors can modify physiological responses in exercises performed at maximal and supramaximal (at and above the intensity corresponding to maximal oxygen uptake - VO2max). Therefore, the objective of this study was to analyze the main factors related to these physiological responses and their implications to performance. Among the important factors for the performance at these conditions, is the VO2 kinetics, since a faster adjustment can contribute for the increase of tolerance to exercise. Some factors associated to the running economy (RE) can influence the middle distance performance, however the mechanisms are still not elucidated. The muscle fibers recruitment can contribute for the optimization of the energy expenditure and the delay in the onset of fatigue. Moreover, the choice of the strategy of distribution of the intensity during the exercise seems also have important implications on the performance, being this specific to the duration of the race. In general, the specific training for each running event can induce to important improvement on the VO2max, the speed corresponding to VO2max (vVO2max), muscle activation, anaerobic capacity and, consequently, on the performance. The training in hypoxic conditions seems to generate improvement of performance of middle distance athletes, mainly when associated with the strategy of Living high, training low, that allows important adaptations to exercise and the maintenance of the training ...
