On trainability of aerobic work capacity for crosscountry skiers

基于假定越野滑雪这种实用运动形式的超负荷训练比一般的跑步或肌肉耐力训练对竞技表现更有效的假设，对一种特殊设计的轮滑进行了研究。5名越野滑雪运动员接受轮滑训练，拖拽牵引载荷，训练时间为3至6个月。得到以下结果：两组最大摄氧量均显著增加（33.5 ~ 49.1 ml/kg）。最小)和双杆拖拽牵引载荷的斜坡行走（47.9 ~ 52.5ml）。同样，在3公里固定上坡赛道上的滚轴滑雪测试，以及在600米固定平坦赛道上拖拽牵引载荷的测试中，也观察到明显的改善。因此，这种训练体系对于提高越野滑雪运动员的竞技水平更为实用和有效

Based on the assumption that the overload training in the form of the practical sport, crosscountry skiing in this study is more effective for the competitive performance than the general running or muscular endurance training, a specially designed roller skiing was investigated. Five crosscountry skiers were trained with roller skiing, dragging the tractive load, for 3 to 6 monthes. Following results were obtained. The maximal oxygen uptake was eminently increased with both tests of the treadmill runing (33.5 to 49.1 ml/kg. min) and the slope walking with double poling dragging tractive load (47.9 to 52.5ml). Similarly in the roller skiing test on the fixed uphill course with three kilometer of distance, and also in the test dragging the tractive load on the fixed flat course with 600 meters, the prominent improvement was observed. So, this training system was thought to be more practical and effective for the advance of the competitive performance in the crosscountry skiing
