Theoretical justification technology of special endurance development in training process of 400 meters runners

In the article justification technology of athletes’ special endurance development specializing in run on 400 meters is given and will be more effective in training process which is based on the accounting of staging and sequence of physiological mechanisms improvement and functional properties defining it at the differentiated selection of training influences according to these regularities, and purposefully to combine the main training loads and additional resources of ergogenic influence.
