Abstract/OtherAbstract:
Sandbakk, Ø, Welde, B, and Holmberg, H-C. Endurance training and sprint performance in elite junior cross-country skiers. J Strength Cond Res 24(x): 000-000, 2010-The purpose of the present study was to investigate the relationship between aerobic characteristics and sprint skiing performance, and the effects of high-intensity endurance training on sprint skiing performance and aerobic characteristics. Ten male and 5 female elite junior cross-country skiers performed an 8-week intervention training period. The intervention group (IG, n = 7) increased the volume of high-intensity endurance training performed in level terrain, whereas the control group (CG, n = 8) continued their baseline training. Before and after the intervention period, the skiers were tested for 1.5-km time-trial performance on roller skis outdoors in the skating technique. Maximal oxygen uptake (&OV0312;o2max) and oxygen uptake at the ventilatory threshold (&OV0312;o2VT) were measured during treadmill running. &OV0312;o2max and &OV0312;o2VT were closely related to sprint performance (r = ∼0.75, both p < 0.008). The IG improved sprint performance, &OV0312;o2max, and &OV0312;o2VT from pre to posttesting and improved sprint performance and &OV0312;o2VT when compared to the CG (all p < 0.01). This study shows a close relationship between aerobic power and sprint performance in cross-country skiing and highlights the positive effects of high-intensity endurance training in level terrain.
