The article presents the correlation dynamics between indicators of arm speed strength abilities (explosive arm power, speed strength endurance) and sports results of elite cross-country female skiers at various distances of races for the final year of Olympic training. The analysis involved the results of 18 elite female athletes specializing in various types of competitive activities, aged 20 to 27 years. Functional surveys of arm speed strength abilities were conducted in the laboratory of cyclic Olympic sports of the All-Russian Scientific Research Institute of Physical Culture &amp; Sport (Moscow). The test program included the maximum muscle load on a ski ergometer Concept-2 (SkiErg), simulating the work of the hands with competitive intensity in several modes (pushing with maximum power and 5 minutes of work in competitive mode). The obtained indicators of explosive arm power and speed strength endurance were subjected to a correlation analysis with the results at the goal-setting starts of the sports season 2017-2018. The research results allowed to establish the most informative indicators and the differential significance of arm speed strength abilities in ensuring the effectiveness of performance at various distances of ski races.
