My results are on your son’s web page.

But since there was no comment section, noting a couple things here –

1. I’ve been ill for the past week. I think that’s messed with my metabolism, heart rate, response to caffeine, etc. so the results may or may not be useful. [footnote: it has given me a jump start on the B7 challenge however]

2. As something of a coffee addict, I suspect I’ve developed a tolerance to caffeine. On the other hand, I’ve been ill for the past week (see #1) and my intake has been down, so I think I’m experiencing withdrawal. Not sure what the net effect is.

3. One of the readings seemed aberrational, but results is results. Unless that is, in fact, the anticipated effect of caffeine, I assume the protocol can deal with outlying data.

4. Will your son publish his results for us to see?

Regards,

I did the test but think I may do it again tomorrow since my data seems flawed compared to others. I got up, drove to work, sat still for 20 minutes to get my heart rate down and then started. While my HR went up in first 15 minutes, then it went down and actually went below starting HR for 45 and 60 minutes.

0 – 70
15 – 74
30 – 70
45 – 67
60 – 66

Does this mean my starting HR was off (very possible) , that I am a freak of nature (very likely) or that I crashed after the caffeine injection?

FC, should I record the results or do a do over?

What? No placebo for a control group?

I completed this today while I was in one of “those” conference calls. The results should be on your son’s site. I must say the worst was having to limit myself to just one cup of coffee between 8-9 this morning. Well and also sitting out the last 15 minutes while I really wanted to get up to go to the restroom.

Good luck to your son let us know when the data is posted.

0:00 – 52bpm
0:15 – 51bpm
0:30 – 52bpm
0:45 – 53bpm
1:00 – 51bpm

Parked my butt in the Lay-z-boy, rested for 15 minutes prior to starting the experiment, drank the sodas, read my Mountain Bikers Training Bible for an hour, recorded the final measurement, ran like heck to the bathroom to process said beverages. I risked kidney damage in order to keep the experiment as clean as possible. Your welcome!

Thanks for the sofa time!

I did this for you fatty (well, your son anyway). I think I drink too much caffeine as it barely had any effect on my HR and I actually felt more relaxed after the soda intake…

In bed rate: 41
pre – 61
0:00 – 65
0:15 – 61
0:30 – 55
0:45 – 56
1:00 – 53

Over entire time frame the HR monitor gave a max: 70, min: 51, excluding the 84 when I had to get up and unload the coffee.

I guess I need to drink more coffee.

All in the name of science right?

Scott R.- Good question. Can Mrs. Fatty’s, (no disrespect intended), jewelry be admired on-line anywhere?
