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 (VO₂max) and oxygen uptake at the ventilatory threshold (VO₂VT) were measured during treadmill running. VO₂max and VO₂VT were closely related to sprint performance (r = ~0.75, both p < 0.008). The IG improved sprint performance, VO₂max, and VO₂VT from pre to posttesting and improved sprint performance and VO₂VT 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.
本研究旨在探讨有氧能力与速度滑冰表现之间的关系,以及高强度耐力训练对速度滑冰表现和有氧能力的影响。10 名男性和 5 名女性精英青少年越野滑雪者进行了为期 8 周的干预训练。干预组(IG,n=7)增加了在平地进行高强度耐力训练的量,而对照组(CG,n=8)则继续进行基线训练。在干预前后,滑雪者在户外的滚轴上以滑冰技术进行 1.5 公里计时赛表现测试。在跑步机上进行测试时测量最大摄氧量(VO₂max)和通气阈下的摄氧量(VO₂VT)。VO₂max 和 VO₂VT 与冲刺表现密切相关(r = ~0.75,均 p < 0.008)。IG 从测试前到测试后提高了冲刺表现、VO₂max 和 VO₂VT,并且与 CG 相比,IG 提高了冲刺表现和 VO₂VT(均 p < 0.01)。本研究表明,在越野滑雪中,有氧能力与冲刺表现密切相关,并强调了在平地进行高强度耐力训练的积极影响。
