Polar fitness test... changing my training?(10 posts)

Polar fitness test... changing my training?gnailuh
Feb 11, 2003 10:24 PM
I've been using my polar 610 for a year and a half now. I've only been able to complete the fitness test twice... I have pretty low resting heartrate and my heart beats skip a little (docs said it's all fine). Well, the fitness test always fails... last time I completed one was April of 2002. My index was 57... didn't have heartrate predict on. So I've always used the formula, at 28 yrs, it's 192. So I've always trained appropriately in those zones. However, I've never really hit mid or high 90% range... always thought I was not pushing too hard.

Well, I just was able to complete on today. Resting heartrate of 38-42 and a Vo2 max index of 62 with a predicted max of 178... is this trustworthy? If so, then I've been working and training at a MUCH higher zone!!! But I've felt ok at these zone... my so called 80-85% is now 86-91%, way above AT...

What do you think? Keep training at my old levels, just realize that it's no a high %... or scale back? If I thought my current aerobic rides are boring... what will I think now?
Trustworthy.....absolutly NO!K-Man

I have the S-510 and I know my max HR is between 203 and 205. When I first did the test it calculated my max at about 184 using the "test". Thought maybe my old HR monitor was off? Fist ride and I was easily in the mid 190's at points of my ride. Have reached a max of 201 at one point this year so I know my "actual" is correct and the Polar test is hogwash!
By the way I'm 38 if it matters at all.

Ditto. Same age, same max. (nm)shirt

I have had my VO2 max, max HR, and threshold tested at a physiology lab (on the bike testing, by a PhD).
My VO2 max as predicted by my 710 was off by a 0.3, so i would not say that the test for VO2 max is that bad. Having said that, the researcher said he had no idea how the function actually works and it may be that I just fit the algorithm well. In regards to max hr: Because you have reached a specific heart rate that does not mean it is what shoud be used as your max HR for training zones, exercise, etc. Your heart rate is dependent on a number of factors including amount of rest, hydration, etc. For instance, I have hit heart rates of 204 in the past 6 months, however, my max heart rate was tested as 187.
Also, for those who are interested in the calorie usage of the 710, it also matches up extrodinarily well to my actual calorie usage as measured. It is with in about 2% of actual usage.
doesn't make any sense ?K-Man

If you hit a Max HR of 204 that would be you max HR. Just because when you tested it was lower, why on earth would you now consider that your max HR.
MAXIMUM HR is just that the maximum HR you can hit. If you have seen it hit 204, I think logically that would be your max, not the lower rate.
Maybe I'm just stupid?

I believe that max hr is based on the ability of your heart to pump blood efficiently. Additionally, dehydration during exercise will artificially elevate your max hr. As for myself, I currently believe data obtained in a human performance research lab under controlled condition and as I obtained training zones based on lactic acid levels I am not overly concerned about my max. I was also curious of how I could have a hr so much higher then my max hr so I spoke with the PhD doing the research about this. He maintains that people will often see HR above their max hr and this is most often due to dehydration. However, I will be going back in for testing in march and will post the results and compair the results with each other and with the hr seen is races.

The Polar fit test is not an accurate determination of your VO2 max. If you don't have access to a lab or the money for a lab, are not a racer, and really have no burning desire to go find your VO2 max, I'd say take that number and chop 10 off it for a ballpark guess at VO2 Max.

It's easy to find your approximate Max HR if once again you don't have access to a lab or the money. If you've got health insurance, go get a stress test and tell them to put you on a hard protocol and have them tell you Max HR.

Other than that you can use this non-clinical method to get close. Get on an indoor bike, warm up for 10-15 minutes and then ramp yourself up with the resistance knob keeping a good 80/90 pedal cadence for the most part. The ramping process should take about 10 minutes total with you at 100% effort for at least a minute or so. Give it all you've got and go until you just can't go anymore. This will get you closer to an actual max HR than the 200-age thing.

Make your calculations from there.

35 here. Actual Max HR 193. VO2Max 59 kl/kg.

A Vo2 max of 178? Lance Armstrong's Vo2 Max is 80. Travis Brown's Vo2 is 72. Where are you geting these numbers?

Dude, I didn't type heartrate... Vo2max of 62 and max heartrate of 178... everyone else read it and knew what I was talking about... read between the lines man.
good indication, but not exactmorency

my polar says vo2max=58 - max heartrate=188
a conditiontest done by a doctor with exact readings showed a vo2max of 62 and a max heartrate of 194
