INTRODUCTION: As an endurance sport the cross-country skiing requires high VO2max, high oxidative enzyme activities and high anaerobic threshold [Millet et all, 2003]. A number of studies have investigated different factors and training methods relevant for cross-country skiing performance. To our knowledge, studies have investigated the effects of sport specific interval training on performance in cross-country skiers [Nilsson et all, 2004]. The aim of the study was evaluate the effect of high- intensity uphill interval training on some physiological parameters. METHOD: 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 participated Eight weeks training model has been done after the winter season during the preparation period. While basic trainings are loaded for preparation to winter at the same time with the purpose for preparation to roller skiing uphill races additional to all these trainings 3 days in a week. All-out roller ski exercise has been applied on the 2 km distance uphill track where the height difference is 144 mt. The training consists of 2x2 km and 10 min rest. Before and after the eight week training session VO2max and anaerobic performances of all athletes were tested. Pre and post tests values statistically are checked via "Wilcoxon Test (2 related samples)". Also differences among the results of a pre and a post tests, analysed from the aspect of percentage changes. RESULTS: Averages and percentage differences have been presented on table 1. DISCUSSION & CONCLUSION: It has been determined that athlete have shown indications of development in VO2max, anaerobic power and capacity, and apart from these 2 km roller skiing performance, as a result of 8 weeks high intensity aerobic interval exercises. Our results indicate the only before and after training session in all subjects. Future research should include a control group for conclusive results. With reference to the training effects found in our study, we suggest that the skiers should integrate the roller ski aerobic high-intensity intervals uphill models in their training programs. --- The hosting University of Jyväskylä is planning to publish conference proceedings "Science and Nordic Skiing III".
