How much human reaction in reaction time?

[GTX JOHN]

On my practice tree I need .320 roll out.

I guess that means I am around ...... .180

Of Course................I am OLD!

Human reaction time, of course, varies from person to person and tends to drop off in both speed and consistency with age. Significant age related reaction time loss tends to happen in the mid-sixties, though that does not seem to be the case with Jim Boudreau .

Human reaction to visual stimulus (bulb) averages around .180. It's faster in response to touch (.155) and sound (.140). It's considered impossible for the human to react faster than .100. in modern track and field, it's considered a foul if someone moves faster than .100 from the gun.

I expect it's fair to estimate the human contribution to the overall reaction time (car plus driver) to be about .200.

How to improve it, well, is another story.

Thanks Bruce, very useful information.

I believe I attended one of your seminars at PRI a few years back. That, too, was very informative.

Maybe 20 years ago, weren't there special sunglasses being marketed that would improve your response time to certain color frequencies?

I've found that there are certain hi vis yellow glasses that do affect how you see certain colors.

You can zero-out the rollout on your practice tree, to test pure human reaction time. I would do that at times, just messing around. My human reaction time (over ten years ago, when I used to race) was in the .175-.180 range. This should give you a close figure. Things vary, of course. But it should be pretty ballpark.

The best glasses are sold by Enchroma and they are not cheap.
They are made mostly for people suffering color blindness. For those that do not have color blindness, you can still use them and it will enhance the colors.

Enchroma has an eye test in their website that will test your eyes for color blindness.

Your other option would be sunglasses with Polarized lenses that have an UltraViolet light absorption coating.

Another area that many don't address is their state of mind and health during the race.

Throughout the years, I have followed what successful drivers do to win and nobody is born with the gifts to win. I have learned it is dedication, state of mind and your health.

Many years ago, in the mid-80's, I recall reading an article about many of the things Jackie Stewart did to prepare himself to win a race. As many can recall, Jackie Stewart is dyslexic, which is considered a disability.

One of the examples was his diet. He didn't consume any alcohol, fats, sugars or carbs at least two weeks prior to the race. His diet was baked fish, legumes, fruits, vegetables, freshly squeezed juice and lots of seaweed. He also abstained eating such things during the event too, until the race was over.

He also had his own way to prepare when he got in the race car; he practiced mind imagery. He would sit in the car prior to starting the car, close his eyes and imagine his body inflating like a balloon. Then he would release all the air out and feel himself relaxed. Taking in to account all the championships he won, it appears it worked for him.

I have found that human reaction should be classified as "individual human reaction". I think when you find your comfortable spot on the third yellow the practice will tighten your reaction range. Then the winning comes from building your car around that.

Think that is the easiest, fastest, best way rather than attempting to change the driver!
