strength efficiency的意思|示意

Better efficiency, more strength and power, and greater training volume without additional breakdown — these are the ways in which cross-training directly boosts running fitness.

更有效，更有力量，更有能量，更高的训练量而没有伤痛——这些是交叉训练直接提高跑步能力的方面。

These are evident in the fish’s speed (up to 70kph) and extreme swimming efficiency, evolution having honed its body to reduce drag and thus conserve strength during transoceanic migrations.

明显的是鱼的速度（最多70kph ）和极端游泳效率，其身体结构的进化可以减少阻力，从而在海洋移动中保存了体力。

Additionally, it has advantages of higher contact strength, wearproof and efficiency in transmission.

同时具有接触强度高，耐磨损，传动效率高等优点。
