Abstract [en]

In modern sprint cross-country skiing, strength and maximal speed are major determinants of performance. The aims of this study were to ascertain the anthropometric characteristics of world-class sprint skiers and to evaluate whether a specific bodycomposition and/or body dimension characterizes a successful sprint skier. Our hypothesis was that body height and leanbody mass are related to peak speed in double poling and diagonal stride. Fourteen male national and international elite skiers performed two peak speed tests in double poling and diagonal stride roller skiing on a treadmill and were analysed using dual-energy X-ray absorptiometry to determine body composition and body dimensions. Relative pole length was positively correlated with both techniques (double poling: only variable that was part of the multiple regression model for both double poling and diagonal stride peak speed. Body height was not correlated with any technique, whereas lean trunk mass (r¼0.77, P50.01; diagonal stride: r¼0.60, P50.05) and was ther¼0.75, P50.01), body mass index (r¼0.66, Ppeak speed. Total lean mass (absolute:arms (both conclusion, skiers should aim to achieve a body composition with a high percentage of lean mass and low fat mass.

A focus on trunk mass through increased muscle mass appears to be important, especially for double poling. The use of longer poles (percent body height) seems to be advantageous for both double poling and diagonal stride peak speed, whereas body dimensions do not appear to be a predictive factor.
