Superficial veins drain blood into deep veins, which rely on the skeletal muscle pump to move blood forward.

浅表静脉回流至深静脉系统是通过骨骼肌的肌肉泵作用完成的。

Other explanations include things like the hypertrophy range increasing muscle pump, improving mind-muscle connection, increasing time under tension, and among many others.

其他解释包括增厚范围增加肌肉泵，改善精神肌肉连接，增加紧张状态下的时间，等等。

Stasis can also happen during long periods of inactivity of the skeletal muscle pump like bed rest or long flights and car rides, or even during pregnancy when a growing baby compresses nearby veins.

血流瘀滞也可以发生在骨骼肌的肌肉泵长时间不做功的情况下，比如长时间卧床、航程、车程，甚至在孕妇中，胎儿挤压到周围的静脉也可导致这种情况。
