This study is aimed at analysing the variability of oxygen parameters in subsequent annual training cycles at championship training level in mountain running. The study employed the following indirect methods: the Astrand Test, Conconi Running Test, and also a direct method (Bruce Test). Research material is a young, talented 28-year-old athletic mountain runner. Research results were obtained within 4–5 years period, which were as follows: VO 2max 83–90ml/kg/min – increased on average to 2–3 ml/kg/min per year, HR max 172–177 beats/min, PPA 158–169 beats/min. The case study was carried out within the framework of longitudinal research and was used to collect data for the formulation of a specific exercise profile in a new, dynamic sports discipline. The research aims to serve as an example of a novel method of conducting training microcycles to the cyclic lifting aerobic capacity athletes.
