For six weeks, participants performed a daily plantar flexor stretch, or calf stretch, of their dominant leg.

在六间里，参与者每天进行一次主腿足底屈肌拉伸或小腿拉伸。

But the good news is that we can heal most of the neck pain, and the plantar fasciitis, and the repetitive stress injuries, and the back pain that we suffer.

但好消息是我们可以疗大部分脖子痛、足底筋膜炎，反复应力性损伤和背痛。

The problem is, again, we tend to carry too much weight and we don't have the mechanics that allow those less-supportive shoes to not create things like heel spurs and plantar fasciitis.

问题又是，我们往往会承受过多， 且我们没有足够机制让那些支撑力较弱鞋子不会产生足跟骨刺和足底筋膜炎等问题。
