Compression clothing?

Compression clothing has shown an increase in venous return, which helps to remove lactic acid from the muscles post exercise, thus facilitating the recovery process, which alongside stretching, post exercise nutrition and adequate hydration, may offer some people results. I'm not sure I personally agree with the whole "fatigue reduction" statement though....

Evidence?

"helps remove lactic acid"

Lactic acid is actually a fuel, not a caustic waste product. Muscles make it deliberately, producing it from glucose, and they burn it to obtain energy. The reason trained athletes can perform so hard and so long is because their intense training causes their muscles to adapt so they more readily and efficiently absorb lactic acid.
