According to the NFLPA, their data found that players have a 28% higher rate of non-contact lower extremity injuries when playing on artificial turf, including a 32% higher rate of non-contact knee injuries on turf and a 69% higher rate of non-contact foot or ankle injuries on turf compared to grass.

As baseball player Dick Allen said, "If a cow can't eat it, I don't want to play on it".

I'd like more detail on timeframe of study as it relates to the more modern field turf vs the 70's version of green asphalt....are we talking all of that or just more recent on the more advanced versions?

I would imagine it is recent. Usually older data are joined in with more recent data for comparison.
