All skiers performed a 2 × 2-kin all-out uphill intervals with roller-skis, 3 times a week, in addition to their traditional training program. Measurements included VO2max (maximal oxygen uptake), anaerobic power, and also for 2-km roller ski. 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-kin roller ski performance were significantly higher during all post-test trials in all groups (P 〈 0.005). With reference to the training effects found in our study, we suggest that the skiers should integrate the roller ski aerobic high-intensity interval uphill models in their training programs for improving performance.展开更多
