The purpose of the work was to characterize the 4-year preparation cycle for the Winter Olympic Games in Pyongyang (2018), the leading Polish speed skater M.W. Longitudinal tests included assessment of aerobic and anaerobic exercise capacity determined in laboratory tests, respectively in the graded bicycle ergometer test and in the Wingate test performed with the lower extremity. The longitudinal data from exercise tests obtained in the analyzed 4-year period of preparation for the Olympic Games clearly indicate a significant improvement in the skater's exercise capacity. In the examined period of 2015-2018, the athlete obtained an increase in VO2max value by 6.5% to the level of 55.8 ml/kg/min. The nature of the observed changes in selected exercise indicators corresponded to the assumptions and implementation of training plans. The examined athlete was very well prepared for qualifying starts in October-November 2017 and she won three Olympic qualifications at distances 500, 1000 and 1500 m. During the Olympic Games, the Polish representative started the competition with starts at distances 1500 (20th place) and 500 m (28th place). At the leading distance of 1000 m, the competitor started at her level, reaching 12th place thus fulfilling the pre-start assumptions.
