Objective of the study was to assessment of the dynamics of relationships and its variability between heart rate variability indicators in young skiers during training loads.
Methods and structure of the study. Heart rate variability was assessed in 12 mass-class skiers aged 13,2±0,4 years using the MS FIT system (Medicalsoft, RF) before and after exercise in a sitting position. The training load was a cross-country run with an imitation of an uphill run alternating with running. Five series of 10 repetitions of an uphill run of 150 m with a slope of 7-9º were performed.
Results and conclusions. The relationships between the indices of cardiac muscle functioning are significantly modified by physical activity. Evaluation of the functional state of athletes and their level of performance using only quantitative data of the heart rate variability, without assessing the dynamics of the relationship, can lead to incorrect interpretation of the results obtained.

Keywords: heart rate variability, young skiers, training process, performance.
