Re: Troubleshooting a model D sensor cable?

Yes, I understand that it doesn't sample fast enough. But if there is anything going on at the time the sample is taken by the DMM, it will sample something , sometimes - unless of course the sample is taken over a time interval, and "something" oscillates around 0 during that interval. Anyway, I cu...

Re: Troubleshooting a model D sensor cable?

No, I don't have an oscilloscope.

But I assume that the DMM would at least start showing an unsteady signal between ground and tip when the flywheel is spinning? It doesn't. It shows constantly infinite resistance.

Troubleshooting a model D sensor cable?

My PM5 reported a problem with the sensor cable. I want to fix it myself, so I searched the forums and found some recommendations of measuring the resistance between the connectors on the plug. Apparently 650 ohm is a normal value. So I pulled the plug (haha) and discovered that it has 3, not two co...

Re: Doing something wrong, or impatient?

1) 3'/2'/1' @ 16/18/20 02:49 02:43 02:38 That is a quite weak stroke. Approx. 4.4 wattminutes per stroke. With your history, I would have expected twice of that. To hold a 1:50 pace, you would need 60 of those strokes per minute. That is is not feasible. So if you want more speed, you need a strong...

Re: Is COVID-19 affecting your training program?

Same in Denmark. I am a member of a rowing club and a kayaking club. Both were closed down yesterday. We are allowed to go and get our gear, but we are not allowed to use the training facilities or any other facilities. I have even heard that some other clubs have closed down so hard that members ar...

Re: Apple Watch Calories vs. PM5 Calories

The armchair metabolism of 88 kcal per hour is remarkably close to 100W (88*4.2*1000/3600 = 103 J/sec), often taken as the default base metabolic rate. Pure coincidence. It is a function of the body weight I have entered in Garmin Connect. You can call it insignificant, but it still adds up to arou...

Re: Apple Watch Calories vs. PM5 Calories

300 kCal/h to allow for work done not on the handle. ...and to allow for being alive... This has come as a surprise to me, but apparently it is kind of a convention among exercise trackers to include our basal metabolic rate (BMR) in the calorie estimate of an activity. If I start an exercise activ...

Re: Feedback on SPM and Drag Factor

And to fall into a rhythm and adjust it from time to time could have the same effect of pausing in the recovery. No. My recommendation was to adjust the rate by generally slowing the recovery a bit down or speeding the recovery a bit up. If this leads to pauses in the recovery, someone is clearly n...

Re: Apple Watch Calories vs. PM5 Calories

The conclusion is that more than 80% of the observed weight loss is due to water leaving the body either by breathing or sweating. As far as I can see, that was actually the premise, which jamesg used in his calculation. If the body's efficiency is 20-25%, this means that 75-80% of the combusted en...

Re: Feedback on SPM and Drag Factor

Probably very obvious: Rate 20 means every 3e second one stroke. If you focus on PM-monitor that means, start a stroke at *:00, *:57, *:54, *:51, *:48, *:45, *:42 etc. I am not so sure that this is a good strategy. It will be very tempting to pause somewhere in the recovery and wait for the right t...

Today where I dropped as low as 19 SPM: https://log.concept2.com/profile/932893/log/42632913 Managed to keep roughly the same pace/watts, but yeah, it was quite a lot more jerky and not smooth, hehe. More practice to do! There is one more thing, you could work on: A more consistent stroke. Strangel...

Re: Feedback on SPM and Drag Factor

Or is it "where" i rest? Should I rest at the front, back, or move forward slower? 🤔 You shouldn't rest. You should be in constant movement during the recovery. I prefer to do the start and the end of the recovery as a rather fast motion and slow down a lot in the middle of the recovery. It makes e...

Re: Feedback on SPM and Drag Factor

For example, if my SPM should be lower, will a higher drag factor help that to feel more natural? Probably the opposite. When you increase the drag factor, the flywheel will spin down more between strokes. When you lower your stroke rate, the flywheel will also spin down more between strokes. So if...

Re: New Concept2 rower PM5 won't turn off

the ErgData app was also automatically added to my personal phone. I checked the Bluetooth setting and it was indeed connected to the PM5. This sounds a bit strange. The problem with the persistent Bluetooth connection keeping the PM5 on after a row is well-known, but it usually only occurs after a...

Re: Footstraps slipping

..and to add to the excellent advice already given: If it is a technique problem, you should do some sessions strapless. This will force you to stop your backwards motion by pulling the handle, not by pulling the footstraps. The force you put into the footstraps is not measured in any way by the C2 ...
