The energy costs of skiing with the diagonal stride technique was investigated in 15 members of the men's and women's national cross-country ski teams and in 5 recreational skiers. Oxygen uptake was measured directly by means of a portable bag-method for each subject during level skiing at 3 different skiing speeds. The oxygen cost of double poling vs. diagonal stride techniques was also measured in 3 subjects during level skiing. Although a strong linear relationship was found between VO2 and speed of skiing (r = 0.868, p less than 0.001), there was considerable variation even among elite competitors. The VO2-skiing speed relationship was parallel to that obtained for running, but the O2 cost of skiing was found to be 10--12 ml/kg in excess of that predicted for level running at the same speed. On flat terrain, the O2 cost of the double poling technique as used in fast skiing was found to be higher than that for diagonal striding.
研究人员对15名男女国家越野滑雪队队员和5名休闲滑雪者采用对角滑步技术滑雪时的能量消耗进行了调查。在3种不同滑雪速度的平地上滑行时，通过便携式气囊法直接测量了每位受试者的摄氧量。还对3名受试者在平地上滑行时双杖滑雪与对角滑步技术的氧气消耗进行了测量。尽管发现摄氧量（VO2）与滑雪速度之间存在很强的线性关系（r = 0.868，p < 0.001），但即使在精英选手中也存在相当大的差异。VO2与滑雪速度的关系与跑步时的关系平行，但发现滑雪的氧气消耗比以相同速度在平地上跑步预测的氧气消耗高出10 - 12毫升/千克。在平坦地形上，快速滑雪时使用的双杖技术的氧气消耗高于对角滑步技术。
