What are you using to do the data analysis for Fitbit? I can see graphs on the smartphone app and can see peak heart rate but I have not seen Average HR anywhere.

Web interface shows avg.  Don't really use the Android one.

When you end the workout on your watch. it will show you the time of the workout, peak, average, and calories burned.  Also if you go into the app ... at the main dashboard. Go to "weekly exercise" and it will show you your workouts and will show those three things. And if you go into one specifically, it also says average right there.  Maybe the app needs to be updated on your phone?  Hope that helps

So DS says racing Spec Miata is like "Motocross with a cage"  I would like to see him on a moto X track.  Now John D. says "Spec Miata racers are athletes" Oh boy...
and I thought I would take up a little old lady hobby of SM racing, now I find out I am a Moto X blasting panty dropping jock.   

 

Don't give yourself too much credit there Kevin.

I decided to play yesterday and put my heart rate monitor on. Using a polar h7 strap monitor.
Started the session as we pulled out for the pace lap.
25 min session
Avg: 124
Max: 146
36% fat burn
236 calories.

To be fair, this is the fittest I've even been in my life. Was excited to see the data overall.

Fun stuff

av8tor - since you called me out, again, an FYI - I raced Moto-X and Super X in the late 70's and 80's for about 10 years in South Africa, was the elder statesman of the Blue Stratos Kawasaki team that gave the world Greg Albertyn (World Motocross Champion in 1992, '93 and '94, AMA Champion '99), Colin Dugmore and Robbie Herring (Multiple UK Champion and manager of the UK Motocross Des Nations Team). Won 13 of 14 races in 1983 season.

 

Competed agains US riders Rex Staten, Larry Wosik and others who came to South Africa to compete. Also competed in Offroad endurance, enduros, hare scrambles etc. Competed in the legendary Roof of Africa 3-day event.

 

During my MX career I broke pretty much every major bone in my body, 9 major surgeries including 6 knee reconstructions, and spent a week in a coma that finally ended my 2-wheel racing. Apparently I was read my last rites by a priest while in the ICU with my mom standing over me ......

And on the subject of fit-bit while racing, my experience is that it totally over-counts movement. It uses a motion sensor to count steps and it gets way too many inputs when riding over gator strips. The heart rate might be more accurate, but I would completely discount the calorie burn numbers

[Danica Davison]

HAHAHA yeah Kevin get owned!

 

Danny - I noticed that too. I think the calories are still burning for sure...but my race that burned 800 calories I am sure was a bit over exaggerated.  I think it counted like 300 steps or so at Roebling. That shouldn't be contributing too much to the overall calorie burn but it definitely helps. I think it would be somewhere in the 200-400 calorie burn range for a 20-30 min race, depending on age, weight, temperature, and other variables.  Me being younger, I should burn more than an old fart and should have higher heart rates as well.

 

Your max heart rate that your body can physically handle is about 220bpm minus your age.  That would put mine at 195 and would put yours at 161 (you're 59 right?).  So naturally, I will burn more calories.

 

Xav - I am thinking about getting chest strap monitor.  I read those are more accurate, especially during exercise. Will look for a cheap one.  I notice yours are reading a little bit lower than mine.  Curious what your age is.

John - I have used my cycling Polar chest strap heart monitor in my car sporadically over the years, and logged heart rates typically between 110 - 140. I have seen peaks of 150 that I suspect are related to near-misses, but have not been able to find a way to extract a bpm vs time trace to overlay over video so I cannot say for sure.

 

In my high school days, as an cross-country and middle distance track athlete in South Africa (before my motocross and windsurfing exploits) I was tested at the Witwatersrand University Exercise center. Back then as a 16 year old I was able to briefly get anaerobic values in the 190-200 bpm, deep in lactic acid territory, and logged some some pretty serious VO2 max numbers that I don't recall. My resting heart-rate back then was 42 bpm but has since climbed to around 55 bpm at the age of 59. No matter what activity I do these days, I am unable to get anywhere close to my younger max bpm.

My bet is your highest bpm readings come when you radio to Tom, about those ESR cars and Jeffy Boy cars are so much faster then yours!

I did my first ice race over the winter and sawing at the wheel on the ice gave me an extremely exaggerated step count lol,  something like 22,000 steps when I did 5-7500 max.  I don't think the rumble strips matter but as I've seen you drive in the rain Danny and it looks like ice racing!

I agree.. I wear one as well and I get crazy amount of steps when in the car.. I am thinking the steps counted in the car are somewhere in the neighborhood of  3x what it should be.

[Steve Scheifler]

In rough numbers, someone weighing 180 lbs jogging at 5mph on level ground burns about 10 calories per minute. Someone burning several hundred calories in a 25 minute race must be behind the car pushing it.

Currently 38, turning 39.  My max heart HR is 192 (tested).

 

Here is a graph of the event.

 

[Danny Steyn]

My wife Kim and I are currently in Africa visiting my family on the safari parks we manage in Swaziland. Both of us were logging more than 18,000 steps on a 90 minute game drive, just sitting in a Land Rover, bouncing over the dirt roads. So I would discount ALL steps counted while driving using a fit-bit type motion counter.....

[Danica Davison]

It would make sense to figure out how many calories you burn per step. And then eliminate the calories burned from these "steps" in the car.  Thus, leaving you with calories burned from heart rate/metabolic rate/etc .

[CruzanTom]

Late to this thread but, yes, I use a Garmin Forerunner 225 to monitor workouts and heart rate. When racing my SM,  I regularly turn the GPS off and turn the HR tracking on. HR in race is similar, but not quite as high, as when running. For background, I am 61 but have a high MAX HR, ~190. A high MAX HR is simply genetics (like blue eyes) and does not indicate health status. The better judge is what is your % MAX HR while exercising or racing and comparing the two. Racing 30 minutes should elevate your HR similar to a 30 minute run/jog. 

 

Over the last few years, I find my HR getting lower during qualifying events. I assume it is more experience with the tracks, the car and less stress. In racing, I have found that my average HR started dropping off as I became more experienced. Then, my AVG HR began climbing during races - I realized that I am more often engaged in extremely close, intense racing. After some races, I get out of the car almost breathless. The concentration required for 45 minutes of door-to-door racing without mistakes certainly elevates my HR.

 

The better shape you are in, the easier your heart can maintain elevated HR without taxing your other bodily functions, e.g., concentration. That's why fitness is a part of motorsports. On the other hand, there are excellent racers who do not appear fit. My theory is that those drivers are skilled at relaxing while maintaining their high levels of concentration and focus. They have mental fitness, if you will.

 

I don't log steps while racing (GPS is off) but I do during the rest of the race day. I get many steps walking around the paddock, finding the toilet, looking for beer, pulling Davison out of the sand, etc.

 

Finally, my theory is one mile of running negates one beer. I try to run a mile for every beer I drank the day before. I don't have a race laps/beer equation developed yet but I am working on it! So far, its 10 laps/beer.    (AFTER the race).

You ... 45 min door to door racing without mistakes?  I call Bull Sh!t ! More like, fender to quarter panel, tire to tire, bumper to door, etc. I think THAT may be why your heart rate is spiking. 

 

And you have no idea how nervous I was sitting in the sand trap with you out there on track.  I thought for sure I was going to get wiped out on the next lap by you!

 

At least I didn't hit a car under the black flag.  How high was your heart rate for that?

Rubbing is racing! Unless you're in a SE30.

There was so much sand between you and the rest of the track that I would have needed a two-humped camel to get to you.

He had his back up lights on! That's my story!

I agree with this. There is a reason why most of these race car drivers at a pro level are in such good shape.  At the very least, it doesn't hurt to be in shape.  I am excited to try it out again this week at Daytona ... going to watch the heart rate rise in the bus stop ... and go back down to resting heart rate on the banking will I drink my tea
