The Apple Watch 4 has FDA approval for its EKG monitoring. It also collects HRV data, but I haven't seen any guidance from Apple on how to interpret the HRV data. PubMed search indicates that a lot of research has been done on HRV.

Yes I know about Apple. I think it is FDA clearance and not approval.

All of this reminds me of another small world story... when I was at Cantimer and we were searching for investment, we considered strategics. For example a range of companies in the hydration business. One company we discussed was Camelbak. If I recall correctly, they had a decent slice of their business in DOD in addition to the consumer space. We thought there might be interesting synergies.

When I studied them I quickly discovered that there CEO was a college classmate. When we got on the phone, we had a fun trip down memory lane. We had both lived on the top floor of Hitchcock Hall... top of the **** was its nickname.

And right around that time, Gatorade's SSI was experimenting in NASCAR with a special hydration system-- I think they ran it in early 2008. And the head guy at SSI was an ex-college wrestler, fully aware of the hydration measurement challenge in wrestling.

I had a chance to monitor my heart rate (HR) at the track this past weekend. Ambient temp was 85-95 F over the pavement, and it felt hotter than that when it was sunny.

My normal resting HR when indoors is in the 50s. Outdoors in the heat, my resting HR went up to 70-100, which is more increase than I expected. Sitting in the grid waiting to go on track, my HR went up to the 100-120 range, maybe partly or largely due to adrenaline. On track, within minutes, my HR climbed up to about 170+, and stayed there for most of the track sessions.

So my conclusion is that, despite not feeling like I'm exerting myself much on track, my HR gets as high as any other strenuous activity, including trail running uphill.

It will be interesting to see how the numbers compare during a track event in cooler weather.

Cool (ha!) results. For most people in motorsports, there is no question it's strenuous activity. We were at Indy this weekend and it was 90s in the paddock with track temps over 120F. In the car was around 130F! That is very tough on the driver.

Interesting stuff. Thanks for sharing. Any way to monitor your blood pressure with this?

I haven't seen a wearable blood pressure device. If there is one that transmits Bluetooth, Bluetooth LE, or ANT+, we could add it. Do you know of any?

i'll check w/ my wife (cardiologist). I assume there are spikes in the BP during racing/driving but don't know how long that is sustained and what the regression looks like. Curious for health reason.

This one seems to fit the bill.

None that I've seen or can even recall even referenced. We've done heart rate, breathing rate, blood oxygen, eye tracking, glucose, and a couple more things, but never blood pressure.
