Objective of the study was to test and analyze the kick double pole skate skiing biomechanics versus the technical and tactical fitness rates for the cross-country and biathlon.
Methods and structure of the study. We video-captured the competitive performance of the sample on ascends for further analyses to compute and analyze the movement biomechanics rates.
Results and conclusion. The cross-country skiing and biathlon groups was tested with the highest speeds in the starting lap, followed by its fall in laps 2-3 in biathlon, and growths in the final lap in the cross-country skiing group due to the increased striding frequency and stride length. The stride length in laps 1 and 3 showed significant intergroup differences. The knee joint extension rate in lap 1 was higher in the biathlon group (2.09 versus 1.76 rad/ s) and in the final lap in the cross-country skiing group (2.16 versus 1.97 rad/ s). The study data give grounds to recommend the skiing speed being increased using more balanced strength management scenarios to economize the movement biomechanics at the early competitive stages.

Keywords: biathlon, cross-country skiing, kinematic characteristics.
