A study of performance cross-country skiing movement

在2012财年，我们揭示了越野滑雪过程中最大努力的周期特征、运动学和动力学。因此，我们发现疲劳的影响改变了运动学和动力学。在2013财年，我们展示了越野滑雪者在跑步机轮滑上的心率和最大摄氧量。结果表明，轮滑运动的机械效率随跑步机负荷的增加而增加。

In fiscal year 2012, we revealed cycle characteristics, kinematics and kinetics of maximal effort during cross-country skiing. Therefore, we showed that kinematics and kinetics were changed with influence of fatigue.In fiscal year 2013, we showed heart rate and VO2max of cross-country skiers on treadmill roller-skiing. And, it was revealed that the mechanical efficiency of roller-skiing increased with the increase of the treadmill load.
