Ask a bunch of pro rasslin' historians, and you'll get a different answer from each of them... some claiming pro wrestling was never legitimate competition. Some will say that only world championship matches were "shoots" (no pretermined outcome), while typical matches had a winner selected in advance, like today's WWE.
From what I've read about guys like Farmer Burns and his protege, Frank Gotch (Iowa native, world champ 1908-1913), I've come to the conclusion that most of their matches would've been legit... but I'm not sure.
The oldest known pro wrestling film in existance is the 1920 Madison Square Garden title bout between Joe Stecher of Nebraska and Earl Caddock of Iowa (Gotch's protege; Gotch died in 1917). The 20-minute segment I've seen of the two-hour match looks "real" to me -- in fact, other than the uniforms (full-length tights, no shirts) and the roped-off ring, it looks like a modern amateur wrestling match. No costumes, no off-the-top-rope theatrics.
In the 1920s is when pro matches became more theatrical, with aerial moves, whipping opponents into the ropes, that sort of thing. Wrestlers were cast in roles as good guys/bad guys, playing off ethnic stereotypes. Costumes started to make an appearance. Women's wrestling was also launched about this time, as were tag teams. Time-limits started about this time, too. (Until then, pro matches might go on for 2 or more hours... one went on for 8 hours!)
One reason why pro rasslin became more theatrical in the 1920s: Competition from other sports. Football was really becoming popular. Boxing was huge, with guys like Dempsey and Tunney. Baseball was also finding a national audience with superstars like Babe Ruth.
It was in the early 1900s that organized amatuer wrestling started to take off, as a counterpoint. Eastern colleges like Columbia and Penn State launched their programs 100 years ago. U of Iowa's first program was 1911; Oklahoma State was circa 1917, when Ed Gallagher arrived on campus.
Back in the early days of HS and college wrestling, there were similarities to pro wrestling. The uniforms were pretty much the same -- trunks and/or tights, often without shirts... many schools wrestled in rings... and some submission/punishing holds were allowed. In the 1930s and 40s, the rules were changed to ban dangerous aspects like the double-wrist lock and the full-height bodyslam. During World War II, rings were banned. In the mid 1960s, the NCAA required wrestlers to wear shirts.
