Dear Mark: Should I Consume Caffeine Before My Workout?

By Mark Sisson
177 Comments

In today’s edition of Dear Mark, I cover a topic near and dear to many of your hearts: caffeine. But I don’t just cover caffeine; I explore whether caffeine truly does act as a diuretic, especially during exercise, and whether or not caffeine can actually be helpful to athletic performance. Should we all be downing mugs of joe or cups of tea before we hit the gym or head outdoors?

Let’s find out.

Dear Mark,

I’ve been told that drinking coffee prior to, or during workouts is a big no-no, because it’s a diuretic and will lead to dehydration, which is no good for performance (or health). But I love an iced coffee right before my workouts. I feel like it helps. It could just be placebo, but if it’s not hurting, I’m okay, right?

I wonder if you could give me the lowdown on what the literature says. Thanks!

Anon

First, let’s tackle the dehydration question. It has undoubtedly become “common knowledge” that coffee is a potent, perhaps the most potent, diuretic, that drinking it is like drinking negative water, and that if you’re stuck on a desert island you’d be better off drinking your own saliva than that steaming cup of joe from the Starbucks that inexplicably decided to set up shop on a desert island. Yeah, there are a lot of scary stories about coffee, but does it hold up to scrutiny?

No. A quick search on PubMed turns up a couple German-only studies with vociferously and unambiguously worded titles but no abstracts (“Coffee does not cause dehydration!” and “Coffee does not dehydrate. New studies of Germany’s favorite addiction: coffee.”), as well as some English ones with abstracts:

  • One from the University of Connecticut measured fluid, electrolyte, and renal indices of hydration over eleven days of caffeine consumption in human subjects. Doses of up to 6 mg caffeine per kilogram of body weight had no effect on body mass, urine osmolality (urine concentration), urine specific gravity (concentration of excreted materials in urine), urine color, urine volume, sodium excretion, potassium secretion, creatinine content, blood urea nitrogen (forms when protein breaks down), and serum levels of sodium and potassium, causing the researchers to conclude that caffeine does not cause dehydration.
  • Another compared hydration markers in patients who consumed either caffeinated beverages (coffee and cola), non-caffeinated beverages (coffee and other sodas), and/or water. The effect on hydration status was essentially uniform across all beverage categories, regardless of caffeine content.
  • And finally, a review from the American College of Sports Medicine found that not only does caffeine not reduce hydration nor induce electrolyte imbalances, it has no effect on heat tolerance during exercise.

I think that settles that. Caffeine does not dehydrate you or cause you to overheat. It’s “safe.” It’s not bad for the active athlete.

But is it actually good? Does it do anything except fail to dehydrate you?

Oh, yeah. Let’s dig into the literature to find out what it can do for your athletic performance.

Endurance Exercise

Most of exercise/caffeine literature centers on endurance training and performance. I remember back when I was running, the most oft-cited benefit to caffeine before a race or training was that it would increase the oxidation of fat, thus sparing muscle glycogen. That sounds nice and tidy, and it would be awesome if it were true, but the most recent evidence suggests that caffeine has little, if any, effect on fat or glycogen metabolism during endurance exercise. So what are we to make of the older evidence that does show a difference in fat oxidation after caffeine ingestion? Or the 1992 study that found caffeine reduced the tendency of muscle to burn glycogen early on during extended bouts of exercise, thus “sparing” it for later on?

It may be that caffeine simply makes exercise more tolerable, makes muscles work harder and better, and allows those exercising to do so harder. One study found that while pre-workout caffeine did not spare glycogen, it did boost the endorphin response to exercise. If endorphins are high, exercise is more tolerable, even enjoyable. If caffeine can increase the runner’s high, it’s also going to make exercise more effective and more self-perpetuating.

Whatever the case may be, the literature is pretty clear that caffeine improves endurance performance, perhaps by enhancing fuel partitioning or making exercise more tolerable and enjoyable.

Anaerobic Exercise

The extent of research into the effects of caffeine on anaerobic performance – think sprints, weight lifting, and interval training – is limited, but useful literature exists. One review, from 2009, noted that while caffeine appears beneficial to speed endurance training (in the realm of 60 to 180 seconds) and high intensity interval training (HIIT), it has limited use in power sports. It may help lower body muscle endurance, but it appears to have a minimal effect on the upper body. The authors propose a number of mechanisms for caffeine’s action, including enhanced calcium transport and the old fat utilization/glycogen sparing thing, but the most promising idea is that caffeine simply stimulates the central nervous system enough to blunt adenosine receptors, increase pain tolerance, and dampen perceived exertion.

What about resistance training? In one study, caffeine ingestion boosted trained women’s 1RM in the bench press (PDF). In another, caffeine seemed to have no effect. A review from 2010 determined that short-term, acute ingestion of caffeine is beneficial in team-based and power sports, but mostly in individuals who did not routinely ingest caffeine. Six of eleven resistance training studies reviewed in the study showed benefits to caffeine ingestion, so the evidence remains fairly equivocal.

Thus, when you drink coffee before lifting heavy things or sprinting, your performance will not suffer – and it may even improve.

It may even be a simpler, less exciting explanation than anything overtly physiological: that the “benefits” of caffeine to physical performance may actually be a cessation of the negative effects of caffeine withdrawal. As Sweat Science points out in a recent post, before double-blind trials on the effect of caffeine on performance, participants must abstain from caffeine for a day or two. If they’re habitual caffeine fiends (as many people are), by the time they begin the study they’re already suffering withdrawals. Studies on cognitive performance and caffeine have found that when you account for the withdrawal effect, caffeine has little to no benefit to performance. Researchers have yet to examine the withdrawal effect in studies on athletic performance, but it appears a likely candidate for at least some of the reported benefit to caffeine consumption.

It’s also important not to lose sight of the fact that most of us are drinking coffee, not popping pure caffeine pills. Coffee contains tons of polyphenols, bioactive compounds that could have beneficial (or negative) effects on exercise performance. Most of the studies are looking at caffeine, so they have to isolate it. But if you’re drinking coffee, shouldn’t you look for studies that examine coffee? There’s a recent one that found ingesting coffee polyphenols increased fat oxidation (PDF). Of course, the caffeine, polyphenol, and other bioactive compound contents of coffee are not stable. Coffee is a food made up of hundreds of factors. It’s not just a source of caffeine. Based on soil conditions, climate, elevation, roast, and variety of bean, two cups of coffee can display remarkably different characteristics, and it’s likely that the effects of each on exercise performance will also differ.

Bottom line, though: if coffee makes you perform better, keep drinking it before, during, or after you workout. At least we can say for sure that it’s not dehydrating you.

How does coffee affect  your workouts? Better? Worse? No effect? Let me know in the comments!

Two problems with coffee:

1) It’s addictive. I don’t want to anything in my body, especially a stimulant, that creates its own need.

2) It negatively affects sleep and rest.

3) It’s probably inflammatory to your internal organs

I’ve switched to drinking herbal teas. A great way to get a wide variety of nutrients into your body. Coffee leaves may have nutritional value, but they are a mono nutrient if you consume the same plant every day.

Don’t have one. However, it was on a list of inflammatory foods. I eliminated these foods from my diet (gluten, sugar, corn mainly) and my liver enzymes dropped back to normal and my cholesterol dropped back to normal. So I just have my own experience to draw on. Maybe coffee wasn’t causing the inflammation, but I have enough reasons to stop anyway i.e. don’t like being addicted a stimulant. I have horrible withdrawal symptoms, mostly bad headaches.

2) Dig around for yourself but this is one of those oft cited myths. Its true initially, but once tolerance develops the effect on sleep doesn’t exist.

Chris – caffeine sensitivity can develop for some people, especially as they age. For other people, that doesn’t happen.

I am very caffeine sensitive – but I have a friend a few years older than me (63) who drinks large mugs of coffee at bedtime and sleeps like a baby. If I drink one 6 oz cup of regular coffee in the AM, it disrupts my sleep that night.

Actually, I think some people are sensitive to coffee’s effect on sleep. I used to drink coffee regularly, so I had built up a certain amount of tolerance. Nonetheless, if I drank some after a certain time (which got to be earlier and earlier), it definitely kept me awake. And it wasn’t in my head because there were times when I’d ask for decaf out and would be jittery and wakeful anyway, indicating the barrista likely forgot and made it regular. Since I was expecting decaf and no such effects, it couldn’t have been in my head! My mother was… Read more »

I only have about 1.5 cups of black every morning AFTER 40 oz of water. No sleep problems since I don’t have it after 7 am. drinking it all day is a dreadful idea for a multitude of reasons. Small amounts are good for you, although I bet all day dependency probably is inflammatory to some extent. And to echo many others here…yes, it gets things moving nicely. And delicious!

I agree big time on the first two points you’ve brought up. Anything you just ‘can’t live without’, regardless of its influence on internal health, can’t be good for overall well being (It might be aiding your training but what about your mood, behavior, stress levels etc.)? If our body becomes less sensitive to stimulants as exposure continues, it makes sense that drinking coffee on a regular basis would cause us to require more of the stuff to get that same ‘pick me up’.

Given the plethora of caffeine-based energy drinks available, I don’t see why a person would drink coffee before a workout, even if it is iced coffee, an energy drink can provide adequate caffeine while being easier on your stomach. I like coffee as much as anyone but I don’t understand how drinking it before engaging in intense physical activity is going to yield good results.

There are a lot of review sites online that discuss caffeine content, flavor etc. of the various energy drinks.

Personally I like Rock Star Low Carb, which contains substantially more caffeine than their Sugar Free drink.

Bruno

The only way that energy drinks would be considered Primal is if you could point out the Rock Star shrub or Monster plant where the ingredients came from.

Are you kidding me? With the amounts of sugar/sweeteners and sodium in those things?

Don’t get me wrong, prior to going Primal, I used to drink at least one of the big cans of Rock Star every day. They’re delicious, but they’re certainly not Primal in any sort of way.

Energy Drinks are the epitome of processed food/drink.

I’ve been weight training since 2002 and noticed early on that drinking a strong cup of coffee before workouts directly influenced my motivation. I have no proof that the caffeine made me lift heavier, but there is no doubt in my mind that the coffee boost made me more energetic and helped remove the “*sigh*.. here we go” kinda feeling when entering the gym =) (I know, skip some workouts now and then!)

I’ve been having a big cup of black coffee before my full body workouts at the gym for about a year now. YES, there’s definitely a difference. Even if there weren’t a physical performance benefit, concentration is most certainly better when there’s caffeine in the system. Nice to hear it doesn’t dehydrate, though!

For me, coffee + creatine monohydrate (micronized) + aggressive music = a very successful and satisfying workout every time 😀

You don’t have to give up coffee just because it affects someone else in a certain way, if it’s the caffeine that affects you, drink decaffeinated. If you don’t like the taste, great.… Read more »

As part of my dietary cleanup, I examined my daily, heavy (almost a pot) coffee habit. It may have been the low-carb, but I was noticing that the caffeine was doing more harm than good: blood-sugar like crashes, occasional mood disruption, and the expense/inconvenience of brewing. Couple that with the classic ‘I need my coffee’ addiction rationalization, and I decided to 86 it. I’ve felt much better having done so. I now drink tea (mostly green) when I need a body warmer.

Doug…coffee is more than a “caffienated drink”. Mark is not advocating anything other than coffee. Is it beneficial. How about cutting your diabetes Type 2 risk in half with 4 cups per day. How about..”if you are an alcoholic and you drink 1-2 cups of coffee a day you risk of cirrosis of the liver drops more than 20%. If you are an alcoholic and you drink 4-6 cups a day your risk of cirrosis drops over 80%.” Coffee is protective of the liver.

When it comes to hot drinks, anybody who cares about nutrition would strongly advise people to drink a variety of organic, fresh herbals teas.

i always wondered if the difference in studies on coffee were because some used arabica and some used robusto. the latter has a significantly higher caffeine content and probably different quantities of other phytochemicals as well.

i like to be able to use coffee as a stimulant, which becomes impossible when you’re addicted. therefore, decaf use for “everyday” and the high-octane stuff for times when i need a boost fit my style very nicely.

As others here have said, caffeinated coffee makes me pee more – decaf does not. As the cited studies used isolated caffeine, maybe the diuretic effect is a combination of caffeine and some other substance in coffee. At any rate, I don’t find the diuretic effect to be more than mild and adequate water intake maintains hydration. I don’t drink coffee because – as some, but not all people find – I have become more sensitive to caffeine as a stimulant as I age. Going primal only made that sensitivity more marked.

Here’s a way out. Start mixing in decaf coffee with your regular coffee. Do it as slowly as you like, depending on your addiction level. Gradually increase the decaf until is is all decaf. Whole Foods sells a chicory based coffee substitute. Start drinking decaf one day, then chicory the next. Gradually shift to all chicory. Then start drinking a cup of herbal tea a day. Slowly shift from the chicory drink to all herbal teas.

You know, if you do decide to go decaf, there are lots of gourmet decafs available. Swiss water method. No solvents. Organic. Sustainable. Flavored. Micro roast. Whole bean.

Caffeine makes everything more tolerable and enjoyable.

My theory is that people feel like they are becoming dehydrated because the caffeine acts as a vasoconstrictor. This can produce much the same symptoms (like headaches) in people who are more sensitive to it.

“Goddess of Addiction” and I LOVE HER!!

You know that famous logo on Starbucks cups. I call her the “Goddess of Addiction” and I LOVE HER!!

With this Paleo lifestyle of mine, black americanos are my only vice.

How black americanos can be a comfort food, I don’t know, but they are.

Thanks for the research!!

I second Andreas. Drinking an espresso (with heavy cream) before workouts improves my lifting. No idea wether it’s placebo effect or not, it doesn’t really matter to me 🙂

I wasn’t a big coffee drinker, pre primal(up to 2008)

Since 2010 I’ve had 5-6 cups of strong, black french press. (It helped me keep going up to my first food at about at about mid day.)

My TC, 2007 pre primal, approx 220.
TC Nov 2011 ….530 !!

Stopped all coffee. TC now 220 again.

YES! I just read about that effect – with unfiltered coffee. I don’t use a paper filter but a permanent filter. It doesn’t filter the coffee the same as a paper filter. Can leave some grounds like boiled coffee. So that may be why I’ve recently had mysterious elevations in my TC, LDL, and triglycerides – it does all three. Whole ‘nuther reason for me to stop coffee.

After three years of table tennis training, the only think that helps my endurance in a long session of multi-ball/footwork drills is a cup of coffee about two hours ahead of time. No foods, smoothies, supplements helped me. I would be pooped and have to take breaks so I could catch my breath. No more.

I love coffee, but haven’t noticed much of a difference surrounding my workouts other than being more awake if I was a little groggy before coffee. I did notice being more energized after drinking more than usual before a long day hike (this could have been the fresh air and sun light though).

I saw something about coffee increasing stress hormone somewhere (specifically Cortisol). I was hoping it would be mentioned in this post, does anyone know if there is any truth to an increase in stress hormone release from caffeine? specifically coffee?

Yes, I’m shocked no one mentioned cortisol!! Coffee increases Cortisol which is why I drink mostly Green Tea (it does not). Cortisol is related to stress/aging and fat retention. I do LOVE espresso with a little coconut milk and the kick it gives my workouts but I limit it b/c of Cortisol and how it amps up my hyperhydrosis. The only Crotisol studies I’ve seem were from Dr. Pericone. Not sure on his credibility…

What is missing here is a longitudinal analysis. It is one thing to do a study of a bunch of young healthy coffee drinkers and see what it does to their workouts. It is a whole other matter to see what a 3 cup a day habit does to your adrenals over a 20 year timeframe. And where does this fit into the acidity/alkalinity environment and inflammation? In the end it is always a matter of choice. I don’t think Grok downed a cup a Joe before heading out to snag dinner. But if the point of your workout is… Read more »

Can anyone debunk the study that is mentioned here?? http://www.livestrong.com/article/461860-reduced-blood-flow-to-the-heart-during-exercise/
and in a few other websites.. i know it’s regarding caffeine and not coffee specifically, but it would apply to coffee drinkers and im surprised mark didnt address it. it basically says caffeine before a workout reduces blood flow to the heart.

I drink coffee before, during and after CrossFit workouts and can attest without a doubt that it absolutely improves performance, especially at 5:30 in the morning. Coffee rocks!

I dig a coffee, never been addicted, never had withdrawal when I’ve drunk it regularly. I did try chucking it once before I went Primalish because I was having such bad gut issues. (And by that I mean, the shits, all the time.) But now that I’ve kicked the grains habit, coffee doesn’t affect me other than the really good poop thing. It never really occurred to me to have a coffee before a morning workout, but now that that’s out there as okay, I might just do that, because I usually have to wait for the uh, morning poop… Read more »

My experience seems to indicate that reaction to caffeine is a uniquely individual experience. A long time ago, I finally figured out that most of my bouts with insomnia could be attributed to having consumed too much caffeine in one form or another after 3 PM. To this day, if I’m at a party or just don’t think about it and have too much chocolate or a cup of tea after about 3 PM, sure enough, I find myself too wired to sleep that night. But I know lots of people who drink coffee before going to bed with no… Read more »

I typically drink a cup of coffee about an hour or so before I workout. To combat dry mouth sensation, try chewing gum during your workout.

I’m a HUGE advocate for pre-workout coffee.
It works just as well as any pre-workout supplement on the market.
Always a controversial subject of course, but it’s great to have the hard data.
Nice one.

I used to drink the mega-hyped pre workout stims like n.o explode, jack3d, n.o shotgun (don’t judge me, sucker for marketing). They did the job, gave me energy to hit the gym and hit it hard. But now I just mix a cup of black coffee in my pre workout shake. Does the job. And better on the wallet.

Carry on.

I take advantage of the perks of caffeine before/during races (Olympic/Half IM Triathlons). I definitely believe that caffeine helps tremendously during endurance races. I usually take gels with a caffeine supplement throughout the race. I feels like it gives me a boost of speed and my pain threshold seems to reduce. For everyday training, however, I tend to avoid drinking coffee before intense workouts (TTs on the bike/running intervals). The elevated heart rate becomes more uncomfortable and too stressful due to the caffeine during interval sessions. I can handle the stress on race day but not for everyday training. I… Read more »

Coffee and caffeine are NOT synonymous! I’ve found that decaf coffee has the same “moving” effect on my gut as caffeinated and perks me up about the same too. Add to that, I could (but no longer do!) drink a 20oz non-diet Mountain Dew right before bed and have no problems getting to or staying asleep. But coffee, even decaf in larger quantities, much after lunch, and I’ll be up for hours. These days my coffee is at most either two cups during the morning at work (one teaspoon of raw sugar and a dollop of whole milk) or else… Read more »

I find that if I drink a cup or two of delicious coffee AND a couple full glasses of water, wait an hour before running and let some of that water make it back out, then my workout doesn’t end up with dry mouth or having to pee. I think you just have to find what amount of water and coffee works for you, and you CAN’T have just drank two cups in a half hour and then go. You have to pee first at least once. Coffee makes my workouts five times easier.

I don’t drink coffee very often because it actually makes me sleepy, with the exception of a frappe like 2 hours before bedtime. Then I’m super hyper. I’m sure it’s got something to do with the high amounts of sugar. Plus, I don’t really like the smell of it, especially the first thing in the morning.

Hmm…that’s strange. I absolutely love the taste of coffee and drink a cup of black coffee on my rest days, but whenever I consume any sort of caffeine on a workout day I perform horribly. Before I went primal, any form of caffeine – soda, energy drinks, coffee – would make me less coordinated when I played sports. That being said, the sports I did (badminton and martial arts) all required lots of precise movements, so maybe that was why caffeine had a negative effect. Too much arousal isn’t good for mentally difficult/complex activities, or at least that’s what my… Read more »

Read the latest online edition of life extension magazine…they have a fantastic article of the great benefits of multiple cups of coffee a day….I myself am hardcore…I will put 2 tsps of instant coffee directly in my mouth and chase it with water…too lazy to heat the water and clean the cup….works for me…lol

my pre-workout prep involves a tablespoon of almond butter and a small piece of bittersweet chocolate. the caffeine from the chocolate is just enough of a spark to keep things rolling.
