Artificially induced altitudes aerobic and anaerobic performance differences on double-poling ergometer in elite young cross-country skiers

Original language description

Among the key factors for cross-country skier training are high altitude training and strength in double-polling, because has recently been used not only for long-distance races but also for World cup. This study aimed to identify the effects of artificially induced high altitude on acute performance changes during aerobic (AE) and anaerobic (ANE) threshold exercises. Sport-specific tests simulating double-poling cross-country skiing were performed. Methods: Eleven (8 ? and 3 ?) highly trained cross-country skiers (age 19?2.81, BMI 21.9?2.1) performed a stress test to determine individual AE and ANE levels and AE and ANE intensity tests at low (500 m ASL) and artificially induced high (2000 m ASL) altitudes. The altitude was simulated using the hypoxic generator HYP-100?. For double-poling, the ergometer SkiErg ? was used in the standing position. Heart rate (HR) and lactate concentration (LC) in the capillary blood were monitored. Results: For the AE and ANE loads, the average HR values at an artificially induced high altitude were 3?5% higher than those at a low altitude. The differences were significant, both statistically (p&lt;0.05) and substantively. The average LC values were neither statistically significant (p&gt;0.05) nor substantively significant. Conclusions: Not-adapted youth elite cross-country skiers have higher HR at artificially induced high altitudes (2000 m ASL) during the test on SkiErg ? compare to the same load in lowland (500 m ASL). The absence of alterations in the average LC confirms that it is more appropriate to monitor the HR for altitude acute effect assessment and employ LC only for verification. For the management of endurance sports training at high altitude our research confirmed that exercise must respect the principles of acclimatization processes.
