从能量平衡的角度剖析新旧冰刀之间存在的差异,膝关节做功的不同是造成新冰刀输出功率大于旧冰刀的主要原因。在训练中要重视膝关节做功能力的训练,充分发挥新冰刀的优势。
From the perspective of energy balance, the differences between old and new skates are analyzed. The difference of knee joint work is the main reason that the new skates output power is greater than that of the old skates. In the training should pay attention to knee function training, give full play to the advantages of the new skates.
