The purpose of this study was to investigate the 8-week of roller-ski aerobic high-intensity interval training on aerobic and anaerobic power in cross-country skiers. 10 male [age, 18,28±2,1 years; height, 171,26±4,12 cm; weight, 61,39±6,28 kg] and 8 female [age, 16,05±0.3 years; height, 158,3±6,47 cm; weight, 49,34±0.7 kg] junior cross-country skiers completed the study. All skiers performed 2x2-km all-out uphill intervals with roller-skis, 3 times a week, in addition to their traditional training program. Measurements included VO2max, anaerobic power, and also for 2-km time-trial performance. All values were listed as pre-to post-test mean [±SD], significant level, and percentage changes [%]. Pre-to post-testing changes in VO2max, anaerobic power, and also 2-km time-trial performance were significantly higher during all post-test trials in all groups [p<0.005]. As a result, we suggest that the skiers should integrate the roller-ski aerobic high-intensity interval uphill models in their training programs for improving performance.

Roller-Ski有氧高强度间歇训练可提高越野滑雪者的最大摄氧量和无氧能力

这项研究的目的是调查为期8周的越野滑雪者有氧和无氧能力的轮滑有氧高强度间歇训练。10男性[年龄，18,28±2.1岁；高度，171,26±4.12厘米; 体重61,39±6,28 kg]和8位女性[年龄，16,05±0.3岁；高度，158,3±6.47厘米; 体重49.34±0.7公斤]初级越野滑雪者完成了这项研究。除传统的训练计划外，所有滑雪者每周都要进行3次2x2公里的全速上山训练，并使用旱冰鞋。测量包括最大摄氧量（VO2max），无氧功率以及2 km的时间试验性能。所有值均列为测试前至测试后的平均值[±SD]，显着性水平和百分比变化[％]。测试前至测试后VO2max，无氧能力，并且在所有组的所有测试后试验中，2 km的时间试验性能均显着更高[p <0.005]。因此，我们建议滑雪者将轮滑有氧运动高强度间歇上坡模型纳入他们的训练计划中，以提高性能。
