Determinants of cardiorespiratory fitness in amateur male cross-country skiers

Abstract

The aim of the study was to present the performance parameters, their assessment and their predictors in the group of amateur cross-country skiers at the beginning of the preparatory period. For this purpose, incremental exercise tests were carried out on the treadmill. Body composition measurement was performed using impedance analyzer. The main findings of the study were that the most correlated with VO2 relative (max) were percentages of body fat, running speed (maximum) (km/h), running speed (final) (km/h), ventilation (L/min) and physiological cost of running (ml/kg/km). The appointment of the predictors can be an effective tool to assess the efficiency of this group and prepare a proper training plan for them.
