Re: World Rowing Indoor Championships -2023, age groups

Taking the point that the numbers of older rowers will be fewer than those in their prime (assuming you define prime based on age that is!! :D ) however, it seems to me that there is little logical reason to exclude older rowers by lumping them together with their younger counter[parts, as i posted...

Full disclosure: I have a personal interest in this matter. I have trained hard, preparing to compete in 90 through 94 lightweight.
May I take the opportunity to tell you that this is an inspiration to see people of 90+ still actively rowing and competing. Thank you, you are an inspiration for me.

Re: World Rowing Indoor Championships -2023, age groups

But isn't there a huge power difference between a 70 year old and a 100 year old by definition? I can inmagine being pretty anoyed when a 99 year old sets a world record time, but loses the world championship to a guy almost 30 years younger. The 70 year old most likely win, given the physical degra...

Re: Max heart rate

I've always been cynical of that Maffetone assertion, as it's easy to increase HR, if only slightly, through different stimuli that aren't related to training harder. Surely if your HR increases through a stressful thought, that can't affect your blood lactate too, as it's not a result of training ...

Re: Investigating Race Starts

My understanding is that the PMx monitor underestimates the power of your first several strokes, because it uses some default parameters for drag. So in trying to optimize your performance, you are actually trying to do two things, which may be incompatible: maximize your actual energy output, and ...

Re: Max heart rate

Even on long distances? If the length of the piece is such that you are forced to row with a weak stroke and not simply drop the rating, what is the point of the long distance? Well, my point is that with a 20-22 SPM you can still overtrain, even with HR monitoring says you have no issue. Typically...

Re: Investigating Race Starts

100m programed on the monitor removes all the delays, the stopwatch doesn't appear to start until the end of the first drive, or at least you defiantly already moving before the stopwatch starts, there is no other way the PM5 can know you have started. Carl, For what I understand, it seems to depen...

Re: Max heart rate

When rowing, we train the stroke and control output by controlling the rating, so don't need any of the above: keep it below 23 and you are unlikely to overtrain. Even on long distances? My experience is that HR is a bad indicator for overtraining as I typically have issues with my knees not gettin...

Re: watts per stroke vs stroke rate for max efforts

I’m not a fine boat rower but rowed and coached in fixed seat traditional boats. You are certainly right with a crew. I used to do a little exercise of increasing rate with my crew until timing and technique went to pot. 36 SPM was about it for our level of ability, and even then after a few minute...

Re: What the SPI means ???

James, You beat me to it, those were my thoughts exactly: they are the Joules (Watts * Sec). An additional note, the PM5 actually records "strokeCalories" and reports them through the Bluetooth interface (for OpenRowingMonitor I had to find a way to calculate this metric, as we imitate a PM5's BT pr...

Re: ERGdata and Stairmaster HIIT

I've found the pace and distance comparable to within 5%-10% of the C2, while the Watts is more like 20% difference. That is kind of odd: the Power (in Watts) is equal to a constant (2.8 for C2) times the cube of the boat speed. So if you get the boat speed near to Concept2's, you should easily be ...

Re: What do you lube your chain with

Don't get me wrong, I think that people should follow the maintenance procedures as prescribed by Concept2. They did the math and see the returns/service requests, so they know from engineering and field data what is needed to keep a machine in good condition. My point is that a chain can take a lot...

Re: What do you lube your chain with

if well looked after they'll last for 10 to 20,000 miles, It quite depends on the use: if there is a consistent force below the treshold, chains can last decades. If a chain gets yanked with brute force, potentially even having torsion in the axis of the chain, it degrades quickly. As rowing machin...
