Current rowing technique is believed faster and safer.
Do you (or anyone here) have any clue as to what that belief is based upon?
For the faster part -- that's easy. Olympic athletes use the fastest technique. They all left the old style and went to the new technique. They would only have changed the technique they used/knew/coached if the new approach was faster. Given racing, a side by side technique compare gives obvious results.
Thanks. The does seem sort of obvious (unless the rowers got bigger and stronger). Anyhow, I only know what I was taught back in the days of iron ships and wooden men (or was it the other way around?). What about current technique makes it faster?
I did read a study on safely based on the load applied to the spine a few years ago that exactly answers your question, but now I can't find it. The claim was that the spine was in a biomechanically superior position to handle the force of the leg drive in the current technique than in the old one. I did trip across these while looking for that study.
This discusses the implications of shoulders first "the rower swings hard with the upper body, diverting more stroke force through the upper body and increasing rib cage pressure."

In my physician days I sub specialized in treating chronic pain. Regardless of position, when rowing all of the stroke force must go through the upper body. Not sure how the rib cage pressure gets increased except in sweep oarsmen that do a lot of twisting before the catch. That being said, I don't remember any rib cage pressure (nor do I feel any now on the ergometer). Further, I don't remember a single soul getting injured on the water. running and weight room is another thing. but, that was back in the day when we were lucky to get an hour on the water in during the week and two on the weekends. Anyhow, those injuries sound more like overuse injuries than specific stress from technique injuries to me. That is a coaching problem if that is the case.
Regarding technique, this is about all I could see they said on it regarding reducing injuries: "Teach athletes how to achieve stroke length with lumbopelvic rotation, rather than flexion and extension of the lumbar and thoracic spine. Some spinal flexion is natural and desirable to effectively distribute load across the vertebrae, but the majority of the power of the drive and reach on the recovery should come from pelvic rotation." The problem is the thoracic spine has almost zero mobility. And, it seems to me pelvic rotation would be hard to do when you are sitting on your butt. Does anyone know of a video describing what is meant here? A lot of what they describe here for technique sounds like what we were doing in the '60's (that is 1960, not 1860 for those who are wondering) so I still don't understand how technique has changed.
"Rowing injuries are primarily overuse related."
This is an interesting paper to me although I am not sure what to make of it. I think it would be of more interest if their subjects had been active competitive rowers rather than "sporty" people who had a familiarity with rowing. Then, we might know if these thoracic curvature changes meant anything other than poor adaption to the stress. Most of the loads in the thoracic spine are taken by the ligaments.
