The study was designed to explore the heart contractive functionality in the speed endurance building process in the differently skilled racing skiers' training system. The heart contractive functionality was tested using tetrapolar chest rheograms during the test practices dominated by the speed and speed endurance building ones. The tests showed that the progress pace of the movement speed building component decreased and the speed endurance increased with the growing athletic fitness rates. Variations of the heart rates and stroke volumes tested in the racing skiers' muscular training process were less expressed versus the prior study data. This progress was due to a variety of speed-building practices included in the training process to train the skiers for competitive ski sprints. The heart contractive functionality profiling studies in the context of the speed- and speed-endurance-building practices will be given a high priority in the junior athletes’ selection and training system design initiatives.

Keywords: speed qualities, racing skiers, heart rate, stroke volume, heart contractive functionality, muscular training.
