I have been working on this for some time. I think it is pretty good now. It is a slideshow lasting about 30 minutes that details 3 areas of physiology that most rowers (most athletes, actually) pretty much ignore that hurts their performance because of these issues. The 3 areas are 1. Muscle efficiency. 2. Fuel delivery. 3. Muscle balance. 1 and 2 are "easily" corrected and should give most a 5-15% power boost if implemented. 3 not so much but that is where the big gains can be found I think. Enjoy. I look forward to an invigorating conversation.

Hi frank, firstly, kudos for inventing the powercrank.
I agree about playing about with the drag, I think a lot of people are not sure on it and are too afraid to play around.
Efficient stroke rate is probably something I think is raised more on the forum than most subjects I see, probably a work in progress for most for at least 2 years, if not longer before someone settles in to their own style.
While people may talk about efficient stroke rate what I have given is a way of actually measuring and determining efficient stroke rate and then transferring it to the water. None of this is easy but if someone is serious about this stuff it is probably worth the effort.
When I was competing it was all seat of the pants. There were no rowing ergometers. No bicycle power meters. It was all a guessing game. No longer does that need to be the case.
Thirdly balancing the engine, I personally think for this a tailor made weights programme suited to the individual is the answer.
But I was eagerly awaiting your solution and I thought "oh ok" at the spring usage for boats, nice way to get an extra advantage and nothing in the rules not to say you cant, as you say.
The device was intriguing, between 2.75 and 54 watts extra. I take it that you recommend using the device all the time?
I would assume so considering you recommend springs can prob be used on a boat within the rules, so that would indicate not just training but competition also?
Let me draw on my powercranks experience again. The cyclists who saw those big PowerCranks gains were those who used them all the time. Those who used them part time never got through the transition (transition was complete when PowerCranks were no harder than regular cranks, even on the long hard rides). I always felt you needed to train for the last 10% of the race, not the first 10%. Rowers may have it a little easier because their races last 7-8 minutes, not 5-6 hours.
I don't have.a clue what one can do. Well, I do have a clue, I just don't know what the full potential is.
The device made your shoulders fatigue after 3 to 4 mins, on a 210 drag I am not suprised lol
You misunderstood. What made my shoulders fatigue was the pushing the couple of pounds, not the 210 drag factor. I have been using 210 drag factor for a long time without issue.
I get the concept to use the device to highlight weak points in the body and the principle is a bit like a smith machine in a gym, a balanced weighted assistance effect.
If the device were to be used as a training aid then great I can see the principle, but would not recommend the usage of such a high drag for most people. You are doing tens to hundreds of reps and weak points will go pop on the average person. Lower drag needed there I feel.
I disagree. I, again, go back to my PowerCranks experience. A few years ago after I figured out the importance of this pedal speed stuff all it seemed to take is about a week or so at the new resistance before it would feel normal to the rider. We all like what we are used to. Cyclists experience those forces 80-90 times a minute for hours on end. Rowers should have no trouble adjusting to a slightly harder resistance 30 times a minute for shorter periods of time. Anyhow, what I am advocating is to simply do the testing and then try to adapt to something more efficient. I'll bet it would be easier than you fear.
I do rather get the idea that you are recommending it as a permanent thing, to used every time, hence the extra watts as mentioned above. I do feel that this will create new imbalances within the body as one will be too reliant on the extra weight just to get a better time, and some muscles will become untrained due to the assistance.
What muscles will become undertrained in your estimation. Oarsmen transitioning to pushing resistance have an advantage over cyclists transitioning to PowerCranks. You can add tiny weights slowly and only increase as it becomes easy. The cyclist suddenly had to lift the entire weight of the leg all at once. Most people's first ride lasted less than 5 minutes and they would have trouble getting off the bike. Lots of cyclists gave up on the PowerCranks because they were afraid they would lose fitness during the transition. This was never an issue for those who stayed with them.
Obviously it comes down to how one would want to use it, an extra 54 watts might give me 5 tenths on my 100m time or maybe 30 secs on my 5k time.
The faster you are the less an extra 5-10 watts gets you because shell resistance is not linear.
I think it is the age old argument of technology assisting athletes, lighter bikes, the power crank, spring loaded tracks and running shows, streamline swim suits etc.
Again, I disagree. This is not doping, simply utilizing our God given ability to analyze data and come up with a better way of doing things. If there is no prohibition to what one does then the medal goes to you if you are first across the line. I don't have a clue what the time potential really is. If you are rowing simply to get a good workout when what I suggest is a wast of time.
I think today for the blue riband event of a 25 mile cycle tt. The only recognised record attempt has to be done using 1970 bike technology, do correct me if I am wrong.
There comes a point when we rob our selves.
When it comes to cyclists it doesn't matter because if they train on PowerCranks and have a new ingrained pedaling pattern it doesn't matter if they are on 1970's bikes. When Greg LeMond first saw the PowerCranks he said to me "I worked for years to learn how to pedal this way now people can learn it in months." The winner usually has the best engine, the equipment hardly ever matters but the equipment gets an awful lot of credit (because that is where the money is). My suggestion does require an equipment modification but it is legal and available to all so the winner should still be the one with the best engine.
You congratulated me on PowerCranks. Have you had experience with them? Or, know someone who did?
My guess is the first person to do this will be some sculler who is just below the top tier who doesn't have to convince anyone but himself to give this a try. We will see.
