INTRODUCTION: Sprint races, which have become more widespread since the 1990s, lead skiers to specialize in different branches [1]. Studies conducted in recent years state that in this type of race, during which anaerobic performance and strength are important, athletes should have different features anthropometrically, physically and physiologically [2].The aim of this study is to examine the relationship between sprint exercises performed at different distances using the roller ski training model and anaerobic performance. METHOD: Ten volunteer male skiers ages 19.3±2.5, with heights of 173.3±6.2 and weights of 67±8.4 participated in the study. The measurements in the study were performed in a laboratory and on a tartan track using the V2 skating technique. The roller ski used was Pro-Ski C2 (Sterners, Nyhammar, Sweden). The applied anaerobic strength test of the leg muscles was a Wingate 30-second cycle ergometer test. Spearman rank correlation test was performed for statistical analysis. The value of p<0.05 was accepted for statistical significance. DISCUSSION: A difference between the distance of the exercise and the parameters applied in the study was determined. While a significant positive correlation was observed between 200 m roller ski exercise and peak power, a significant positive correlation was found between 800 m exercise and average power. Many studies began to be performed with regard to the increase in the speed factor since the day sprint races began. These studies focus on topics such as equipment technology, wax, technique, strategy and predominantly training physiology [1, 3, 4].In light of the literature and our results, it may be advised that improving the training of the anaerobic average power should be applied for cross-country ski sprinters. CONCLUSION: As a consequence, while the positive correlation value between the exercise performed in short distance (200 m) and the peak power is high, this study demonstrated that as the distance increased (800 m), average power value became more important.
