Health benefits of Autocrossing

At the last GGLC autocross Alex and I decided to try out a little experiment to see how your heart rate changes during the race. We used a Polar S720i to record his heart rate, an iPhone for video and a DL1 data logger to record G-force and speed readings. I used some simple PHP magic to sync the two data files together and used the Chasecam Dashware system to create this finished video.

You can see the speed, heart rate (BPM), longitudinal G (acceleration + braking) and lateral G in the dashboard on the top of the video. His average heart rate was in the low nineties while on the grid and rises to to 101 just before the start of the run. As the run progresses you can see it quickly rise all the way to 145 bpm by the end of the 45 second run. Just as interesting is the way his heart rate falls as soon as the run ends and drops to the low 130s just 10 seconds after the run. So now if anyone asks you why you autocross just say its for the health benefits 😉

Unfortunately the video quality is not as perfect and the heart rate only updates every 5 seconds but all in all it was a successful test of the system. I have already ordered a Polar RS800CX (1 sec resolution) and I plan to run this same setup for the duration of the Lemons race at Buttonwillow next month. So stay tuned for the health benefits of endurance racing 😀

The usual drill. Club members only can sign up in the first week, then it opens up to everyone. Limited car count and at least 12 runs for everyone with lunch being brought on site. Coaches available for pretty much every session to help out if needed / wanted.

Running in the points series is not required, you can simply treat this as a excuse to take your car out for a *spin*.

It will be club members only for the first week. Non-members after that. Same format as we ran last year- mid 60’s max on the driver count and 10 or more runs for the day.

Silicon Valley Auto Group (Lotus of Los Gatos) is back as our sponsor. They will be providing their usual bag of goodies over the course of the season.

May 16, June 27, July 18, Aug. 30, Sept. 19 and Oct 17 will be points events for club members. Same classes and format as last year. We’ll score the best 4 of 6 events.

This season, we’ve got “official” numbers decals. If you’re interested in picking up a set, please visit Chuforia Graffix.

A Few Details:
Make sure your profile is up to date on motorsportreg. The club will be picking up a software package to handle the bulk of the scoring duties. In particular we’ll need to have your car details correct.

Assistance: putting on a autocross, is very much a volunteer effort. There are a couple of area, that we’d like a pool of helpers to cover. Two or three to get the equipment set up. Four or five to help set up the course. We will need you to be on site 7:15- 7:30, to get started.

Thanks and see you at the autocross,

Larry and Alex
