  • This was a very interesting article!
  • Since I got serious with SP back in Oct, I seldom drink coffee in the morning and my BP has dropped considerably. It is not the weight loss because, a few years ago when I lost about 25lbs my BP stayed hi. I was working out seriously at the gym everyday and I asked my doc why my bp was still hi with all the exercise and wgt loss, she told me it was just my family hx, Now I know it was those 3-4 cups of coffee in the am and a few more during day all the way up to after dinner coffee.

    Funny as I was just about to take few sips of my chilled caramel low fat coffee. I decided not to, just because I was running late to my work out anyway. Then I come across this article, funny.
  • "Then they ingested caffeine tablets (equal to 2 cups of coffee) and repeated the same test to measure blood floor prior to and after exercise."

    This is a flawed experiment, with little practical application to the daily lives of Sparkers. The 2006 study was about drinking coffee. This new study is about caffeine tablets. Who takes caffeine tablets...ever? Caffeine is processed differently when consumed slowly and with fat or sugar.

    Can Spark People please get a scientist on staff to vet these articles before they are posted?
  • Good article. I don't drink coffee like I use to. I might have a cup on the weekend. Probably twice out the month.
    There's merit to this idea, but I have low blood pressure, and I think it's partly due to coffee that I don't have to medicate it - I tried meds for low blood pressure once, it wasn't a good trip (and my only trip, fortunately, never done any recreational drugs).

    I don't drink soda, only tea and coffee, I'm much fitter than I was, and I don't actually drink it right before any fairly high intensity activity. Most of my exercise comes from walking and yoga, so I'll stick to my coffee.
  • Ugh. Another study that contradicts other studies. I also saw a different study the other day that said that there's no link between caffeine and high blood pressure. Whatever.
  • This is an article that needs dating--the study needs to be cited/dated, and the article itself, too, should be. As a pp has pointed out, it seems the study is several years old.

    Not only that, but caffeine tablets aren't the same as drinking coffee--the mechanism for internal absorption, rate of absorption, and accompanying ingredients are all different. As a coffee drinker who has, on occasion, used more direct caffeine supplementation, I know there is a significant difference, not accounted for here.
  • I always drink my coffee AFTER my morning runs. This has nothing to do with my ability to breathe or bloodflow, however...The one time I did drink a cup of coffee before running (at least an hour before my run), my stomach was NOT happy. (I had also eaten breakfast with it.) So from now on, I run first, and coffee is my reward!!!!

    I checked the link to the other study, and it does appear to be the same one. Thing is, that study was from January of 2006. It may not seem like that long ago, but a lot changes in 6 years when it comes to nutrition and fitness research. I would like to see more recent studies, with more controlled variables, a wider range of subjects (maybe non-caffeine drinkers as well), and more subjects. While this info is intriguing, there should be follow-up studies done, imo.
  • I have heart arrhythmia when I drink caffeine. This article totally makes sense to me. If the caffeine is decreasing blood flow, the heart beats would get erratic. It's a hard sell in this day and age, though. Seems everyone is addicted to caffeine and PROUD of it.
  • Whoa, this is scary--I've been holding on to a bag of guarana seed powder to add to my pre-workout smoothies once I hit a fat-burning plateau. Glad I came across this first. o_O
  • This makes total sense. I'm a 35-year old who regularly drank Coca-Cola, coffee, etc. Recent heart palpitations and tests that revealed high blood pressure among other things caused me to rethink my caffeine addiction. I still drink black tea on occasion, but gave up the other stuff. I do notice a difference in blood flow...I have difficulty in the uptake of blood in one of my arteries. This has been a wakeup call to treat my body better, and I love not having the tension and headaches all the time. I still eat chocolate on occasion, usually dark chocolate, but so far black tea and chocolate seem to be OK. Thanks for the informative article.
    This is a very good article. My husband who had a quadruple bypass last year walks on a daily basis - lately he consumes two (16) oz cups of coffee prior to his walks. Although one of his bypassed vein failed in the right bottom of the heart , his heart muscle is strong. My point is that he has noticed the difference if he consumes coffee prior to a workout, he tends to be out of breathe. On the days that we juice prior to his walks his ability is swifter. Hmmmm
  • Just waiting for the next study that says people who drink coffee after live longer! It seems things go back and forth.

    I drink my coffee. I will continue to drink my coffee. One of my last races I had a few sips of coffee with my breakfast. The 5k race was at 8 am. I would have had a nasty headache if I just abstained but I didn't want to be running for the bathroom either so just a few sips did me right.

    So I read this and thought "How interesting." and am moving on with my day.
