USE OF GRADUAL ACCLIMATIZATION IN СROSS-COUNTRY SKIERS IN MIDDLE ALTITUDE CONDITIONS

Abstract

Aim. The paper aims to improve cross-country ski training in middle altitude conditions by means of gradual acclimatization. Materials and methods. Seven cross-country skiers aged from 16 to 19 years with the athletic experience of at least 4 years and regular participation in local and nationwide competitions participated in the study. The study took place between June 2017 and April 2018. The following methods were used: literature review, pedagogical observations, pedagogical experiment, heart rate monitoring, performance testing, qualitative content analysis, and mathematical data processing. Results. The model of a summer training mesocycle was proposed consisting of nine micro cycles (first trial, second trial, first basic, second basic, recreative, first dynamic, second dynamic, third dynamic, and recreative). The amount of technical, strength, speed-strength, and general cyclic work in minutes was calculated with respect to each micro cycle. The preliminary training plan was developed. Conclusion. The use of middle altitude training sessions as a part of a year-long training program enhances functional performance and improves athletic results. The proposed recommendations will allow to optimize middle altitude training and, thus, to improve functional capabilities of athletes.
