Competitive athletes frequently use altitude training (AT) to improve sea-level performance. ATbecame interesting for sport scientists and athletes since Olympic Games in Mexico City in 1968. Exercise ataltitude may increase the training stimulus and enlarge the effects of endurance training. The first notedadaptation induced by staying at altitude is an increase in red blood cell mass that improves aerobic power andsea-level performance. Currently, there are several types of AT modalities: traditional ‘live high-train high’,contemporary ‘live high-train low’, intermittent hypoxic exposure during rest, live low-train high andintermittent hypoxic exposure during continuous session. Despite several substantial differences between thesemethods of hypoxic all of them have the same goal: to stimulate an improvement in athletic performance at sealevel. A proper distinction must be made between altitude acclimatization during preparation for competitions ataltitude and AT and acclimatization for improvement of the sea-level performances. Former scientific researchesidentified two longer phases of enhanced work capacity after AT. First phase of enhanced work capacityoccurring between days 3-7 and 12-13, while the best results are achieved during 18 and 20 days after AT.Second phase of enhanced work capacity is reported between days 36 and 48 after AT. The further developmentof practical knowledge in area of AT should predominantly include recommendations about application ofdifferent AT methods in training periodization in different sports. Improvement of the work capacity andduration of enhanced work capacity at the sea level after AT stimuli are the main questions opened for futurescientific researches. |
