Why Coffee Increases Your Heart Rate


Leave the archive and display this page in the standard design: Caffeine - one of the reasons for a high pulse? (high pulser inside)



Hello!

My question is already in the headline, so briefly about me: I smoke and drink, I bike and run.
After my resting heart rate has been around 60 for the whole season and my loving heart can beat up to 4 times a second (max heart rate: 240) I am a little worried. My blood pressure is relatively normal at 140/80. I'm just under 1.80 and currently weigh less than 70kg. During my last examination, various "inner values" such as cholesterol etc. were also completely normal. However, I do not know where my anaerobic threshold is or I have not yet had a professional sports medical examination because the cost / benefit factor speaks against it.
I only notice a sharp drop in performance when it is extremely hot (then my cooling does not cope) and when I run out of juice (nona!). But lately I've been a little bit reluctant to feel my limits, because once I'm over 220, I almost never get it down! At this point, my temples literally pulsate and I don't feel particularly fit (rather just before my heartbeat).
Of course I know that I am not doing my body any good by consuming cigarettes, coffee, beer and wine, but I will not stop as long as I have the feeling that I am "missing" something. I am also working on this psychological attitude (brainwashing) ...
Being "high-powered" is seen as a kind of biometric property of the body and therefore as unchangeable. I am so cheeky and doubt all medical knowledge, although I have no basis for it ... rather, I imagine that my arteries (and other "lines") are somewhat contaminated by various poisons - and a higher pulse quasi "wants" to make up for the undersupply.
My theory is supported by completely independent studies (i.e. completely taken out of context!) On the effects of these substances ... such as: caffeine!

@ ANNEX: on wikipedia the text for this picture is:
Caffeine has a significant impact on spiders, which is reflected in their web architecture. Above the web of a sober spider, below that of one under the influence of caffeine
Actually, I don't want to be a "caffeine spider" because I like to catch pretty butterflies with my web ...: love:
I would be very grateful for suggestions of any kind, of course you can flam me, but then I'll smoke one to cope with it, so show mercy ... please! : wink:

I only know that from my Pa! When the n'RB drinks before driving, the pulse rises so extremely: f: .... I really don't have the "syntom" .... but I also know that coffin has a little performance-enhancing effect: devil:: sm :
: wink:

For a while i drank way too much coffee, and with minimal exertion i got mega-palpitations and had the feeling my heart is racing: Q: but now that i drink coffee by the liter every day, it's okay again! ;) So caffeine can have a negative effect if you overdo it over a longer period of time.

oh ... k!
Actually, I know the solution to my problem: stop poisoning!

I will be hardworking for a whole winter (otherwise I tend to practice idleness in winter) and hang up my brainwashing to dry in spring.

I drink a lot of coffee, I'm a little: rofl: overweight, but despite 4-6 cups a day I have a blood pressure of 115: 65 and a resting heart rate of 48, try to leave out the Tschik, then the coffee tastes like coffee too , even if my daddy says something else, after all, he has 2 stents and i ned, and I've smoked homemade rolls for almost 25 years: p

I usually drink a Red Bull or two before competitions, but generally no coffee.
I don't really notice differences in the pulse, with you it might have other causes ...: rolleyes:

I can still vaguely remember a pathophysiology and biochemistry lecture where it was claimed that caffeine (in non-toxic doses) has no direct effect on the pulse unless you have a heart condition. In the long term, however, it has an effect on blood pressure. A possible increase in the heart rate can, however, come about through the diuretic (dehydrating) effect (indirect influence), hence the recommendation to drink more when enjoying coffee or caffeine.

But I have to look it up in the biochemistry book ...: you:

So, I've now looked it up in the textbook:

Caffeine (in each case in non-toxic quantities!) Acts on the adrenal cortex and promotes the production or release of cortisol and adrenaline. Both are hormones which are also released during escape behavior. They slightly increase muscle tone and act on the waking center of the brain. A short-term increase in blood pressure and pulse is therefore caused by adrenaline & Co., not by the caffeine itself (which doesn't really matter).

What is important for athletes, however, is that the caffeine-triggered hormone release significantly lowers the blood glucose level and can lead to hypoglycemia, which in turn has an effect on performance.

As for the high pulse, I think there are many cyclists who can tolerate a high pulse rate.
At least you should quit smoking, you will not miss anything, believe me.
As for the alcohol: As long as you don't get fat every weekend (or not), I don't think the alcohol does that much, at least during normal training.
Before competitions, however, I would refrain from it.
Drinking for pleasure is certainly allowed.

since i'm also a high-powered pulser - and used to be not averse to alcohol, i know your feeling pretty well:

After a long break with "above average" alcohol consumption in the meantime, my pump was running at full speed, and on longer trips (3-4 hours) I had to watch my pulse very much.

However, I noticed the following: I could, for example, drive longer in the range 180-195 on the ergo, but the watts are in no relation to the "normal" (a minus of about 30%) - what I mean by that: the output in watts stagnates and the heart rate rises, and with that comes the feeling of the kasperl. Consequences: headache, inner restlessness, when you breathe in deeply, you feel the chest bursting - up to 2 days later ...

so stay away from the alk, otherwise you don't need any training - because you won't miss anything, except that it changes you!

I am so cheeky and doubt all medical knowledge, although I have no basis for it ... rather I imagine that my arteries (and other "lines") are somewhat contaminated by various poisons - and a higher pulse quasi "wants" to make up for the undersupply.
I would probably not be able to change your mind significantly.

But the fact is:
the heart works well when it pumps a lot of blood, i.e. when the cardiac output is high. This depends on the frequency AND - at least as importantly - on the stroke volume.
Due to the flow rate of the blood, due to the vascular resistance and, of course, due to the anatomy and mechanics of the heart, pulse frequencies of - at the very latest - over 200 are undesirable, as the loss in volume can no longer be compensated for by the increase in frequency.

That's why the maximum heart rate does not increase in athletes (it actually sinks slightly from 200-210 to about 195 due to the larger volume), but it "only" remains approximately at the same level into old age.


Why you reach 240 is unclear to me, I do not want to put any lay theories into the world. In any case, it's not necessarily something to be proud of, I'd rather have an (stress) EKG done.

since coffee (REALLY!) Junkie now my theses:


Coffee is not coffee
this> 35 sec. Eduscho_Durchrinnplöre is known to be unsound, in addition to too much caffeine, other harmful substances are also removed by the extraction of the bean for too long
Ergo, caffeine is not caffeine
logical .... 1 coffee there is 5 coffee there ...

Caffeine-triggered hormone release, the blood glucose level is greatly reduced
sounds very logical to me, and I think I've seen it before


Fact: if you have a good cup of coffee, it's like having schnapps. Who likes to drink pre-run ...

najo there are some ...

Cheers guys! : U:

Hello!
... I smoke and drink ...

... do not undergo a professional sports medical examination because the cost / benefit factor speaks against it.

What do you mean? If you mean the Eduscho filter coffee .. I think filter coffee is still the healthiest (at least in terms of cholesterol). Actually always drink filter coffee unsweetened with three drops of milk .. a total of about 4 cups a day and I can't imagine what would be unhealthy about it.

the healthiest coffee is the one you don't drink ...;)

Depending on the study ... sometimes healthy, sometimes fatal.

It's just like everything, the dose makes the poison ...

Filter coffee
Think about how long the hot water for filter coffee is in contact with the ground coffee, and how much coffee you have to use to make coffee that tastes great.
The longer the processing time, the more bitter substances / caffeine is dissolved ... along with other 1500 chem. Components.

Espresso / ristretto / cappuccino

Here 6-7g of ground coffee are used per cup. The lead time
of hot water is 20-25 sec.

Its caffeine content is lower than in other types of preparation (90-150 mg per cup versus 150-300 mg for filter coffee)


And actually the most important thing ...

what tastes better ... naaa ....: D

personally filter coffee;)

But it's like you say, either way it's a matter of dose. After all, you can also "poison" yourself with water.

personally filter coffee;)

you're still young, and still have a lot of time to develop good taste ...: devil:;)

All joking aside.

here some more information about coffee ... (http://kaffeeverband.de/pdf/kapitel10.pdf)

I essentially just copy it in there, it fits the topic perfectly

10.10. Is coffee healthy
For many people today, a fragrant, stimulating coffee is one of those little everyday joys that you don't want to do without. Coffee is one of the "luxury foods". Can a stimulant be healthy? As far as the connection between coffee and health is concerned, it can be said today: coffee is a pleasure without regrets!

Medicine and nutritional science state:
Caffeine, the most important active ingredient in coffee, is completely safe for healthy people in normal amounts.

l Coffee perks up tired people. After a cup of coffee we are more attentive, concentrated and vital than before.
l Coffee lifts the mood and promotes a good mood. Coffee is a "wake-up" - but that doesn't necessarily mean that it robs us of sleep. So some people wake up with two cups in the late afternoon, while others only make one cup drowsy.
l There is no addiction to coffee.
l The fact that coffee damages the heart and circulation is a prejudice that can be safely forgotten. Studies with thousands of test persons show:
Coffee and caffeine do not increase the risk of coronary artery disease, cardiac arrhythmias, and heart attacks.
l If you like to drink coffee, you don't have to worry about your holesterin mirror. The consumption of filtered coffee has no effect on the blood lipid values.
l Obviously, certain ingredients in coffee can protect against cancer. The chlorogenic acid in coffee seems to be a protective factor against colon and liver cancer. Other coffee components have an anti-mutagenic effect and protect healthy cells from being converted into cancer cells.
l Women who have a good supply of calcium and who always ensure that they have a sufficient supply of calcium do not have an increased risk of developing osteoporosis by drinking coffee within the usual limits.
l Coffee consumption neither increases the risk of spontaneous and premature births or a below-average birth weight, nor does it have a negative effect on fertility.
l In coffee drinkers, the caffeine content of breast milk increases slightly. If the amount of coffee remains within the normal range, the infant will not show any reaction. There is nothing to be said against normal coffee consumption during pregnancy and in the period afterwards.
l Coffee can be a real digestive aid. For many people, the morning cup of coffee acts as a real "pusher" for the intestines due to the stimulating effect of the caffeine and some roasted substances.
Coffee or espresso after a sumptuous meal will rain the
Stomach acid production and bile secretion and thus get the stomach and intestines on their toes.
l A few cups of coffee a day increases the calorie consumption of our body without supplying any calories. Obese people can take advantage of these properties of caffeine and coffee during a diet. It also helps maintain a lower weight after a successful diet. l Coffee can improve athletic performance. Caffeine activates fat burning in the body and in this way can help provide energy during athletic performance. In addition, the caffeine increases the blood level of certain hormones - the catecholamines, to which, for example, adrenaline belongs - and increases muscle tension and the ability of muscles to contract.

The assumption that caffeine is one of the causes of hyperactivity in children has been refuted. Basically, the effects of caffeine seem to be more beneficial for young people. In scientific tests, the caffeine improved performance and concentration in adolescents, they spoke more fluently and made fewer mistakes on tasks.

Last but not least: coffee can be an important contributor to
Represent nutrient supply. It contains quite a few
vital components and can make a significant contribution to meeting our requirements for minerals and trace elements such as iron, potassium, magnesium and manganese. Health risks for the consumer due to residues and pollutants in coffee must be excluded.
