Well, if I had to characterize it, I would agree that we could each find a DF that worked the best for us, but since we are adaptable, it would not be quite so critical as other things.german answer wrote:Some of us use low drags, some of us use high drags. Don´t you think it depends on your muscle structure and character, what is the ideal drag for each rower Paul?
For example:
What is your goal with the Erg? Moving Boats or Producing fast Ergometer times.
Our physiologies with vary somewhat, though once again, we are adaptable. We are also a single species (well, most of us) so will conform to a rather narrow band of performance parameters with regard to muscle contraction speed, desireable recovery ratio, energy production chemistry, etc... i.e. If you have been around a lot of Erg tests, it becomes relatively easy to spot the "fly and die" folks, and it doesn't have anything to do with how fast or slow the splits are as it is relative to their individual capacities. You or I might think of a 2:00 pace as a "walk in the park" but it could be someone elses "all out" effort.
We may also train a certain way, to make capitalizing on how the PM calculates pace work in our favor with modifications to technique that are Erg Specific. Like your "ultra high DF" training, which slows down the contraction speed by force, another might use Low DF training to increase quickness. It's like swinging a weighted baseball bat to make the real one feel lighter. The effect is temporary but real.
I've had some success with manipulating the DF so that similar handle speeds can be found for longer training sessions as what one would be doing at racing DF and Pace. This helps to create the same contraction speed of the muscles, but under less stress so that the sequencing can be ingrained at teh speed it needs to be. Pulling hard can come later, and is necessarily limitted to relatively short bouts of exercise that are not quite as good for the ingraining of habits. This sort of DF manipulation also allows the ratio to be ingrained, though that can be done by fixing the distance per stroke (DPS) at some value and leaving the DF stable. (For a given drive length [cm], if a constant DPS is maintained, the Ratio of the stroke is a constant.) That final bit is the underlying principle of the S10PS foundational Training that anyone who I coach adheres to. I'll let the results speak to the effectiveness of that training. Dennis and Roy are no secret.
What I look for overall, is not something that works for a very narrow segment of the rowing community (do it or die trying), but things that get desireable results across a large spectrum of individuals (slow steady progress to peak performance within individual capacity).
