Impact of training and competitions in alpine skiing on the anaerobic capacity of adolescent athletes.

The physiological requirements for practicing alpine skiing are both aerobic and anaerobic power, as well as muscle strength and a complex of motor abilities. Alpine skiing competitions consist of four separate disciplines: downhill -- duration of 2-3 minutes at a speed of over 90 km / h; super giant slalom - shorter than the downhill -- 1-2 minutes; giant slalom - is held on very steep terrain with a duration of 60 to 90 seconds; slalom - includes very fast turns on steep terrain, consists of two attempts lasting 45-60 seconds for attempt. The purpose of this study is to track the changes of anaerobic capacity of adolescent alpine skiers during competition season using the Wingate test and the Sargent test. As a result of the study, several major conclusions could be drawn: - As a result of the training and competitions during the period between the two tests, the participants in the study increased their average power (p = 0.02); - there were significant correlations between muscle mass and maximum power ( December - 0.93 ***, April - 0.84 **), average power (December - 0.90 **, April - 0.87 **) and relative power (m December - 0.73 *, April - 0.62 *; *** - p <0.001; ** - p <0.03; * - p <0.05; ns - p> 0.05); - moderate correlations were found between the maximum and average power of the Wingate test and the ranking on the national level of the subjects; - the fatigue index of the athletes increased on the second measurement, probably as a result of the busy training and competition program. The research shows that training and competitions in alpine skiing disciplines allow the development of anaerobic capacity of athletes, which are extremely important for better performance during a race.
