PM5 and ErgData Question

Post by EddieO » November 28th, 2015, 11:22 am

Just received my SkiErg and heart rate belt 2 days ago … impressive exercise machine. Just some basic personal stats before my question: I'm 66 years old, 6'-0" tall, and 170 lbs. For now, I have the damper set to 3.

Question: I'm trying to understand all the numbers being spit out on the PM5 and the ErgData iPhone app. Is there a chart available that explains the "correlation" of how all these numbers relate to one another? At this point, I'm striving for good form, but I also believe these numbers can help an individual use the SkiErg more efficiently … bottom line, I don't know how to interpret them "collectively" in the full scheme of things. I thank you in advance for your time. Eddie

This might explain a little better what I'm trying to figure out …
Those of you that use the information from either source, was wondering if you wouldn't mind posting your favorite combination of data that you're looking at and why. Thanks.

Eddie -

I'll take a whack at your question.

There are many selections of display and units, plus games and administrative functions. These you can explore just by poking buttons or the instructions at
http://www.concept2.com/service/monitors/pm5/how-to-use

Which display and units you find useful depends much on what you are trying to achieve with the Erg.

I'm just in it for some aerobic exercise, helped along by a group affiliation

I am not interested in strength training or competition at any level likely to blow out my aorta. That said:

You will likely find the output per stroke (usually the largest number on the board) to be the most useful. Combined with strokes per minute (upper right corner) you will get an idea of how energetically you are working. Close your eyes and drift into a sustainable rhythm. Look and note the stroke output and rate.

Later you can use the output per stroke number to see how a change in your stroke trajectory may be more/less efficient.

Typically I put up a fixed time or distance (either a "standard" or a custom one previously memorized) and do the run. Depending on units and display selected, something (such as time run and projected finish time) indicates how far along you are.

Split time or distance I do not pay much attention to. Likely useful for competition racers.

FWIW, I've had the SkiErg about six months. I've had a Model B rower for 30 years with close to 20 million meters (after I started keeping track) before having to change to a stand-up machine. I've never set foot (or butt) in a rowing shell; in South Texas there is scant prospect for actual cross-country skiing. Regrettably C2 segregates row and ski meters for the million meter certificates.

Shu, very helpful post … much appreciated.
You mentioned "output per stroke" twice. Exactly what Data Type are you referring to when you say "output per stroke" … Ave Force, Peak Force, Drive Length, Drive Time, Drive Speed, etc?

Thanks, again.
Eddie

Depending on units selected for display it will be
..time to go 500 meters (if every stroke were the same as this)
..watts
..calories per hour
which are "power" terms, energy/time.

If you are really into the mechanics of it,
