It has been about 4 years since I read the studies covering this, so things may have changed a bit but here's the gist.
1) Consuming 6 grams of protein before a strength (not cardio) workout slightly assists in muscle building. Note that I stressed the words BEFORE, STRENGTH, and SLIGHTLY. The protein is digested into amino acids that can be taken up by the muslces after the strength workout (at least that's how the studies explained it). Consuming more than 6 grams produced NO additional benefit. 6 grams is a very small amount BTW.
1) It was never about consuming protein after a strength workout, it was consuming protein with carbs after a workout. Supposedly, consuming protein and carbs stimulates insulin and that stimulates greater glycogen uptake. But 5 studies I read 4 years ago said there was no benefit.
So here's the bottom line. Consuming protein (plus carbs) after a strength workout showed no additional benefit to eating it at any other time, though there's no harm in it, as long is it is part of a normal healthy diet. However, consuming 6 grams of protein before a workout results in marginal benefits.
Honestly, just eat your protein whenever it is most convenient to you, but make sure it is part of a healthy balanced diet.
Lastly, please remember that a recreational exerciser ought to consume no more than .75 grams of protein per pound of body weight.
