Ten male intercollegiate cross-country skiers were studied to identify factors influencing competitive performance and to estimate the efficiency of energy expenditure in skiing. The variables examined were maximum oxygen intake, as determined by both uphill treadmill running and by maximal level skiing, physical characteristics, strength and experience in cross-country skiing and racing. Multiple regression analysis showed that racing experience, cardiorespiratory fitness, and body fat percentage were significant factors in racing success. The net mechanical efficiency at this level of competition was estimated at 21.3%.
对10名男子大学越野滑雪运动员进行了研究，以确定影响比赛成绩的因素，并估算滑雪时的能量消耗效率。所考察的变量包括通过上坡跑步机跑步和最大强度平地滑雪测定的最大摄氧量、身体特征、越野滑雪和比赛的力量及经验。多元回归分析表明，比赛经验、心肺适能和体脂百分比是比赛成功的重要因素。在该比赛水平下的净机械效率估计为21.3%。
