Racepak just released their version of this. They are using it with drag racers to see their "calm" during staging. https://www.racepak.com/collections/...nt=26300190339

There is a lot to learn here. If anyone is interested in a system, let me know.

It's interesting data but I'm not sure how I would apply it to improve my driving. I've got a monitor for running and cycling but haven't gotten around to trying it at the track. A lot of factors influence heart rate (sleep, caffeine, time of day, etc). Heart rate zones vary significantly from person to person and there are a lot of discrepancies. You typically do a specific test at various stages during training to establish a baseline and measure changes. Modern cycling training plans have gone away from heart rate and now rely primarily on power meters because it is more consistent.

I haven't really dug in either. I have one of those logging systems and I have stints where my heart rate is 20bpm higher than in other stints, on the same day, running the same lap times, same car and same outside temps.

ProCoach

Agreed. I spend time with Hunter Allen, a Porsche racer and author of "Racing and Training with a Power Meter" and this is just another data point.

You're right when you are trying to target fixing an exact fitness level with heart rate. Here, we are looking for enviromental triggers and seeing what they are, how the driver reacts, and how to improve that response. Heart rates will increase with stress level, so what causes that stress? Just like we monitor driver inputs to the car because the drivers memory often doesn' match the reality of what happened, many times the driver doesn't know what causes the stress.

I've worked with drivers who where very stressed about starts. With the HR monitor, we where able to figure out what was causing the stress and work to improve their comfort and ultimately performance. Same with someone who had trouble when in traffic with a blocking driver. Knowing what got them excited, something which didn't come out in the debrief but was easy to see in the data, allowed us to work on their race strategy, tactics, and skills.

Of course it is, just like TPS, steering position, brake pressure, etc. But it's the first and one of the easiest ways to "engineer" the driver. We spend so much effort in getting the cars right, but don't monitor the driver who is the biggest influence in what happens on track. I'm surprised you don't agree. I thought I heard something like that in your Watkins Glen track walk with Ross?

I've been fascinated by biotelemetry to analyze and improve my driving recently and have been using a Wahoo Tickr X paired with my Garmin Virb Ultra connected via ANT+ when karting. It's amazing to see and analyze the data overlaid on the video afterwards. I'm still experimenting with it a bit and plan to use the same setup when I hit the track in my Cayman in a few weeks.

The built-in (optional) Porsche Track precision app in the newer cars in combination with iPhone and apple watch provides hearth rate overlays on your data and video.

Very cool. Porsche is on top of their data game. The 919 has more sensors and data channels than you can imagine.

RacePak is such a challenge to use, though...

Matt Romanowski

I posted the Racepak article as another source of how people are using the heart rate monitors. The Wireless Motorsports unit and others will work with any system. They are even included in the AiM CAN profiles for CAN 2. The profiles for MoTeC systems are also available and work very well.

ProCoach

As they do via wireless and Bluetooth in the HD2...

Matt Romanowski

The Wireless Motorsports unit (and Racepak) use Ant+, not Bluetooth. I'm not sure what you mean by wireless (or are you referring to the system?), but the wrist band and Wireless Motorsports unit don't use wifi. In fact, all of the systems out that I know of you Ant+ devices as it's the medical standard.

I don't know if the HD2 has a protocol for it, but Wireless Motorsports doesn't have a specific file for it (see https://wirelessmotorsport.com/pages...emetry-release). If you have one that you want to share, let me know and I'm sure I can get them to post it on their website.

I was reading about some NASCAR rule changes and one of them was to allow drivers to wear heart rate monitors on their arm. They won't allow them to log the data, which is consistent with the rest of their data rules, but it's a sign that more and more race categories are finding value in this data.

Here is a link to the rules change, including some of the safety measures. http://www.nascar.com/en_us/news-med...book-memo.html

Matt,

Here is a quick clip from the monitor we put in the clubsport. Just watch the video and see my heart rate jump when there was a near miss. It takes a little bit for it to drop back down.

The overlay is pretty clean inside of the smart cam
