Abstract [en]

Introduction A high maximal oxygen uptake (VO2max) is of importance for success in elite male competitive distance cross-country skiing (Carlsson et al. 2012). However, it is still debatable how VO2max should be expressed to best indicate skiing performance. Therefore, the purpose of this study was to establish the optimal body mass exponent for VO2max to indicate performance in elite-standard male cross-country skiers. Methods Twenty-four elite-standard male cross-country skiers completed an incremental treadmill roller skiing test in diagonal stride technique determining VO2max. Performance data was compiled from a 15-km classic technique race. To predict performance a log-transformation of power-function model: Race speed = β0 • VO2max^β1 • m^β2 was used, where β0 to β2 are constants, and m is body mass. Statistical analyses used R version 2.13.2 (R Development Core Team, New Zeeland) and alpha was 0.05. Results Participants’ VO2max was 5.39 ± 0.57 l/min (mean ± s) and m was 75.5 ± 6.3 kg. Mean race speed was 5.83 ± 0.41 m/s. The model that best predicted performance was: Race speed = 8.829 • VO2max^0.663 • m^-0.355 = 8.829 • (VO2max • m^–0.535 )^0.663, that explains 69.2% of the variance in race speed for the 15-km classic technique race (P < 0.001). For the VO2max-to-mass ratio within the model, the 95% confidence interval (CI) for the body-mass exponent ranged from -0.947 to -0.122. Discussion The optimal body mass exponent for VO2max to indicate performance in elite-standard male cross-country skiers was -0.535. Moreover, the CI for the body-mass exponent does not support the use of simple ratio-standard scaling and absolute expression of VO2max as indicators of 15 km classic ski racing performance in elite-standard men skiers.
