Pm3 And Totals

[old] denisrricard · Post by **[old] denisrricard** » August 9th, 2004, 8:18 pm

Hello, I've experienced with a few training sets and I like to be able to divide a training session into different segments (or intervals). The only thing is that at the end of the training I'd like to be able to write the total calories burn, total km, including those in the resting phases, etc. When the training stops only the last segment is displayed, and the only place I found *some* of the info I want is on the logcard, except that it's not all there. There are average calories/hr, but no number of calories, no total meters that include resting periods, etc. Am I missing something here? Where can I find that info? Thanks, Denis

On the menu, press "logicard" then "List by Date" and you should get the total meters of your intervals. If you go down to the bottom of the list of intervals, you should see an "r" followed by a number. This is the number of meters that you rowed during the rest period. If you press the "change units" button, the summary will show you the total number of calories you burned during the intervals I don't know how you obtain the number of calories burned during the rest periods. Cheers, Paul Flack

I don't need the calories burned during rest, but the data shows "average calories per hour", not calories total for the interval. There is a difference between your average cal/hr and the actual number burned. Same thing for watts, I'm not sure what to do with that. Thanks for the distance at rest, I'll look for it at the bottom of the list like you said. I just find it strange that these types of totals don't appear anywhere. It's very useful and I'd sure like not to have to add them manually when I have this nice monitor who should be able to provide the info. D.

I just went back and checked and you were right, it is cal/hr at the top of the screen with the "totals" rather than a total calories burned. You will have to multiply the total time by the average cal/hr to get the value that you want. I am not sure you should really be looking at the total calories burned. That number is a guess and not a true readout number. It is derived from a formula that goes something like this: (watts during workout) x (conversion factor to calories) + 300 calories per hour = total calories burned per hour The 300 calories is an estimate of what you burn when you are not exercising. It is supposed to be for normal breathing, digestion, etc. This value has been diputed greatly since it varies by metabolism, age, weight, etc. If you are looking for the incremental calories burned by doing a workout versus watching TV, the total calories will also give you an invalid value. The value only takes into account what you put into the chain and doesn't account for a higher metabolic rate in the hours following exercise. Cheers, Paul Flack

Well I understand it's not a real value of calories burned, but it's a consistent measure to compare workouts from one another. I may be wrong but I take it (the abritrary measure of calories) as a number I can use to compare the work I did today to the one I did yesterday or last week. Since I often vary effort, time, distance, etc. between intervals, and often effort within a single interval, I'd rather have a cumulative number of calories. That way I could, for example, be able to say that I did a 600 calories workout today while yesterday I had done only 500 cal. Those two workouts could have the exact same cal/hr average, but different time and/or effort. In any case, I think it's fun to have a final display with the results of your workout as I like to keep a (pretty detailed) log. We also have a threadmill which my wife uses a lot (she likes walking while I prefer rowing) and she's envious of the fact I can program detailed workout intervals with various parameters, but at the end if I want the totals she has (automatically) on her threadmill I'll need to use a single interval, which is a shame considering how advanced the PM3 is compared to the threadmill monitor. Anyways, thanks for your answers Paul Denis.

Hi Paul and all: I think some clarification is due regarding the below quote by Paul: [QUOTE] "The 300 calories is an estimate of what you burn when you are not exercising. It is supposed to be for normal breathing, digestion, etc. This value has been diputed greatly since it varies by metabolism, age, weight, etc." The 300 kC/hour has always been our best approximation for keeping alive and awake and going through the rowing motion at a reasonable stroke rate on an erg with the flywheel removed. This was arrived at from internal experiments and observations, data from Fritz Hagerman and studies done at Ball State. We never meant to suggest that one can consume 7200 kC a day by just sitting still, and we certainly apologize if there was any miscommunication on our part. Please note the use of "approximation" and "estimate" above, as calories consumed by an individual for doing a given amount of work will vary from person to person, as Paul notes. I have e-mailed Dr. Dudhia regarding this and would expect a revision to his information at some time. Best regards.....C2Jonw

Denis, If you want to keep a running log of the effort that you put in every day, Kilowatt-hours would be better than Calories as reported by the PM3. If you sat on your duff for an hour pulling the chain only hard enough to keep the monitor active, you would get a readout of 301 calories burned at the end of your lazy workout. Kilowatt-hours is a measurement of energy put into the chain over a period of time. It is also the same measurement as your electric meter. Divide the time of your workout by 60 to get the units in hours. Multiply by your average watts listed in the summary portion of the workout. Then divide again by 1000 to get into Kilowatts. When you figure out how much effort you need to row in order to make a Kilowatt hour, you will start turning off all appliances and lights around the house! Cheers, Paul Flack

Ok thanks Paul, I'll do that. Oh and thanks for the "physics of rowing" link c2bill, quite interesting.

Denis, If you care to see all of that 'physics of rowing' information applied in a piece of software, check out <a href='http://www.ps-sport.net' target='_blank'>ErgMonitor</a>. You can download it and use it for 30 days for free. - Mike Niezgoda P.S. It keeps track of all kinds of stats on both work segments and rest segments.
