I think you missed that stated I do a few warmup sets for all of my main lifts and that I lift heavy (5 rep max, sometimes 3rm and 1rm depending on lift and day). However, I believe most people do too many warmup sets which limits their working set and slows progress and gains. Doing 3-4 working sets in reasonable increments is just fine. I know people that do 20 total sets per "body part", only 3-5 of them that are working sets (because that's what the bodybuilding magazine reported <today's Mr. Universe candidate) said they lift).

The running thing seems less likely to be true though. I wouldn't put my bed in a field, sleep 8 hours, hop out and go full out on a sprint, but I'm not going to do 20 minutes of stretching or ride a bike before doing a few sets of sprints.

Long distance warm ups seem even less likely to be needed than Sprints.

And, for what it's worth, I've done "max effort" deadlifts without warming up once or twice. Mostly to show off, but I had lifted those weights before (that day in one case, a couple days back in the other), and didn't have any issues. I could have been hurt, I guess, so my 'anecdata' is no evidence, but even so, not warming up isn't a guarantee of injury either.
