Abstract
The function of height preparations is adaptation of the body to hypoxia (acclimatization), reduced quantity of oxygen in the air, with the purpose of improvement of aerobic abilities of the athlete (by applying aerobic training i.e. combination of interval and continuous methods). By comparing the results of oxygen consumption and other values in the three events in kayak events (200, 500 and 1000m), it was concluded that height preparations have different influence on the said events. With the competitors specialized for 200m the effect of this type of preparation is significantly reduced, while with the athletes at 500m it is greater and it is the greatest with the competitors at 1000m.
