Ski racers' change of speed depends on the terrain engrave, sliding conditions in different stretches of the track, as well as, ski racer's physical and technical preparedness, equipment and tactics during the competition [1, 2, 4]. The ski racers' competitive efficiency and distance gaining tactics depends on the organism adaptation to physical load in different energetic supply zones [3]. The main factors of ski racers' physical working capacity during the competition are as follows: functional capacity of cardiovascular and respiratory systems and production efficiency of mechanical energy in muscles [3]. Physical, technical and psychic preparedness of higt mastery skiers are nearly of the same level and that's why during competition the win is frequently determined by the right chosen distance surmount tactics. The aim of the research - is to analyze the tactics of women ski racers during a skiing competition in Salt Lake City Olympic Winter Games. The meta-analysis and comparative analysis of official skiing competition documents - minutes have been done. According to data, presented in official documents, we have determined the following indices of ski racers competitive activity that characterize it: differences (in per cents) between women ski racers results reaching the first distance part and reaching the second distance part during a competition of 15 km and 30 km distance; mean speed in the whole distance; mean speed of women ski racers in separate parts of the distance we have determined according to ski racers results, fixed in checkpoints; top class women ski racers taken places in separate parts of a distance. The tactics of women ski racers during a skiing competitions reaching 10 km in classical style, 15 km in free style and 30 km in classical style have been analyzed. Totally we have analyzed 149 variants of distance reach tactics. We have calculated arithmetic mean ( ), standard divergence (±SD). Results B. Skari (Norway) the champion of 10 km ski race in classical style was the fastest in the following track stretches: from 5.8 km to 8.7 km - 6.99 m/s and 8.7 km -10 km - 6.67 m/s and in the first part of the track from the start to 2 km her sliding speed was 5.36 m/s (5th place) and from 2.5 km to 5.8 km - 5.49 m/s (2-3 places). Silver medal winner O. Danilova (Russia) in the first part of the distance slid faster than all others ski racers: from the start to 2 km her sliding speed was 5.57 m/s and from 2 km to 5.8 km - 5.5 m/s, but in the second part of the distance she slid a little slower than the bronze medal winner. During 15 km ski race in free style (mass start) only eight ski racers women, who took 1-7 places and 33, 35, 36 places from 1-55, reached second part of a distance faster than the first one and sliding speed of all the rest ski racers in the second part of a distance was lower. Mean sliding speed ( ±SD) of ski racers from fist tenth was highest in the following distance stretches: 1.9 km - 7.5 km - 6.35±0.31 m/s and 11.6 - 15 km - 6.28±0.17 m/s and the lowest speed was from the start to 1.9 km - 5.52±0.05 m/s and from 7.5 to 11-6 km - 6.21±0.04 m/s. During 30 km ski race in classical style 17 ski racers women from 43 reached the second part of a distance (15 km) faster than the first one. Mean sliding speed ( ) of ski racers from fist tenth in separate distance stretches changed as follows: from the start to 7.2 km - 4.99±0.29 m/s, from 7.2 km - 15 km - 5.81±0.12 m/s; 15 km -20.5 km -5.01±0.14 m/s and 20.5 km -30 km -5.52±0.09 m/s (table 1).
