I've taken to drinking a can or two of Relentless before and during matches....

    It's probably not the best thing but I find that it perks me up and keeps me going.....intensity is good for my tennis!

    However, I appreciate its probably not a good thing with all the sugar and whatever other stimulants it contains. If I play an evening match, its harder to get a good nights sleep afterwards and I feel a bit out of sorts / tired the next day.

    Does anyone have idea if there are any health risks associated with this?

    Sugar and caffeine, that's the majority of it. Your body can't burn off all the caffeine and due to this you don't get quality REM sleep, leaving you feeling the way you do then next day.

    Your blood sugar also spikes when you drink these, and your body naturally releases insulin to combat the blood sugar spike. After insulin brings your blood sugar back down, it is usually lower than what it was before the spike. This again is why you feel the way you do.

    Have you tried some low sugar or no-sugar alternatives like 5-Hour Energy or 6 Hour Power? These work best on an empty stomach (or a moderate amount of food with no competing proteins). I will often ingest only 1 oz (1/2 bottle) about 10-15 minutes before an good/thorough warmup. Seems to work best if I perform 10-20 minutes of cardio prior to tennis.

    Do not drink 5 Hour Energy or any of those energy drinks.

    What you're doing is that you are dehydrating your body and those ingredients in those drinks bring more havoc than caffeine. It's worse than coffee.

    You all have been warned.

    ^ Not True. Where did you dig up this misinformation?

    1 oz of 5-hour Energy or 6 Hour Power has only 35-40 mg of caffeine. Do not lump these no-sugar energy shots in with other types of energy drinks. Note that, at worst, caffeine is a very mild diuretic. Some sources indicate that it is not really a diuretic at all. People who drink a lot of coffee have to pee because they drink a lot of coffee/liquid. There is nothing else in the energy shot drinks that I suggested that would dehydrate the body. How much water do you think you are going to lose from drinking 1 to 2 ounces of an energy shot drink?

    If anything, coffee is worse than the shots the I've suggested. There are hundreds (if not thousands) of constituents in coffee. Some, other than caffeine, are known stimulants. Some of the ingredients in coffee are known rodent carcinogens. It is not really known if any are in large enough quantities to pose a serious health threat to moderate coffee drinkers. Jitters and some other other effects of coffee might very be due to ingredients other than caffeine. While I have experienced the jitters and some heart rate effects from 1/2 cup of coffee, I have never had these experiences with 1/2 to a full serving of 5-hour Energy or 6 Hour Power.

    Note: I am not a fan of most energy drink products at all.

    There was a thread all about this, but I can't find it.

    Alright, I'm not disagreeing about coffee, but I can't agree with 5 Hour Energy.
    Since I don't have sufficient data to defend my statement, I can't say anything else except it would be a tragedy if someone died on the court during the summer by drinking coffee or any form of energy drink. :-|

    ^^ no, the evidence on coffee is that it seems to be pretty good for you. A very large meta-analysis of data on coffee drinking was published last year (possibly in JAMA, don't remember for certain which journal) and showed that longevity increased with each cup of coffee per day one drank, up to 5 cups per day. Above 6 cups a day the data got a little less clear. So with coffee the more the merrier.
    Personally, though it seems coffee is a healthy beverage per the data, I wouldn't have it, or any other caffeine beverage, before playing tennis. Both caffeine and exercise can raise your blood pressure (though the effect is small if you drink caffeine daily), and if you happen to take NSAIDs (which also tend to raise BP) when you play, it could lead to a perfect storm of factors raising your blood pressure.

    Your heart rate increases substantially after consuming these beverages. This, when combined with physical activity (i.e. tennis), can lead to heart rate spikes and eventually a heart attack.

    It seems that I was mistaken about the caffeine content of 6 Hour Power and 5-Hour Energy. The former contains ~62 mg of caffeine/oz while the latter contains 75-80 mg/oz (regular formulation, not Extra Strength).

    http://www.energyfiend.com/caffeine-content/6-hour-power
    http://www.forbes.com/sites/clareoconnor/2012/02/08/whats-in-a-bottle-of-5-hour-energy

    There is a significant difference between the caffeine content of a single oz (as I suggested) of 6 Hour Hour Power, a can of Relentless, and a tall or grande Starbucks coffee drink. A (16.9 oz) can of Relentless contains 160 mg of caffeine compared to the moderate amount in the 1 oz energy shots that I suggested.

    To put this in perspective, a 16 oz brewed decaf Starbucks coffee contains 25 mg of caffeine. A Starbucks Grande Coffee (16 oz) contains a whopping 330 mg of caffeine.

    http://en.wikipedia.org/wiki/Relentless_(drink)
    http://www.cspinet.org/new/cafchart.htm

    As I mentioned previously coffee contain numerous chemicals (more than 1000?) other than caffeine. Some of these are known rodent carcinogens but may not be present in large enough quantities to pose serious health risks for moderate/normal consumption levels. Coffee contains chemical agent(s), not caffeine, which stimulates the production of cortisone and adrenaline. Coffee also contains MAO inhibitors, β-carbolines and harmala alkaloids, that may contribute to its stimulating (psychoactive) effects.

    I am well aware that both caffeine and coffee is considered to possess a number of health benefits -- at least with moderate or normal consumption levels. The same can be said of red wine and other substances. As with anything, an over-consumption of coffee can very well be unhealthy.

    While I have experienced negative effects with very moderate amounts of coffee (less than 1/2 cup) while playing sports, I have never felt had this problems with 1-2 oz of an energy shot drink. I have measured my BP on numerous occasions with the latter and have not seen any significant increases. I have seen some slight increases in heart rate, but nothing that would remotely cause me concern.

    He probably didn't.

    I drink 1/2 a 5 hour energy if I have an AM match..I do it sometimes if I just feel sluggish when I wake up. There is no need if you feel awake and pretty sharp when you get up, because then the 5 hour energy will most likely be overkill.

    I think having to have full cans of powerful energy drinks and/or coffee just to play tennis is a sign of poor sleep or poor fitness.

    Olympic athletes ad marathoners use caffeine as a supplement and most of them are in pretty good shape.I spent a bit of time messing around with my pre match and during match nutrition and the best that I found was the 2X caffeine Gu. One before the match and another if the match goes longer than 2 hours. That combined with lots of water kept me pretty good on energy.

    Yes, but he says he is drinking a can or two before a match. That is a ton of caffeine for a sport in which you need to have a settled mind to really play within yourself.

    It is a ton of caffeine in general, and most likely way too much. A sign of poor sleep habits.

    Ah yea that does sound like a lot. The Gu has 38 mg of caffeine which is far less than a cup of coffee. Although I drink coffee pretty consistently too.

    I have a semi sarcastic question for coffee drinkers..Why do people drink coffee in the morning after sleeping 7-8 hours? I would think a person should be at the peak of his alertness in the morning..I can understand the afternoon coffee or if not enough sleep..But i think the morning coffee is just an addiction

    I drink coffee and scotch.

    Personally I think a shot of scotch before a match is more beneficial than coffee.

    I've started drinking about 3/4 of can during the hour before a match to get me ready for the start, and a 2nd can during the 2nd set, or towards the start of a 2nd match if its a two match / day tourney. I have a bottle of orange cordial mix with a small amount of salt for hydration.

    I've done a good impression of a psycho on court on one occasion previously when I had a double expresso beforehand and then a couple of tins of this stuff over the next 3 hours. It's not something I'd encourage, but I find that I actually play better when I'm psyched and fired up. :mrgreen:

    Yeah, I know quite a few runners who do that along. Exactly how much they take, I don't know.

    There's actually a massive industry out there of all sorts of additional sitmulants and supplements that people seem to take. It's not something I'd want to get involved in - caffeine and sugar is enough for me provided its in safe/acceptable amounts. The only risks I can think of is potentially diabetes and elevated heart rates / blood pressure if drunk excessively, but I think you'd have to be taking massive amounts rather than a couple of cans(?). Some of these other supplements are quite controversial:

    Found this table of drinks and caffeine content:

    http://www.energyfiend.com/the-caffeine-database

    Assuming its accurate, Relentless doesn't seem too bad? Equivalent to 3-4 strong(ish) cups of coffee?

    2 cans = 320mg caffeine

    one cup brewed coffee = 108mg caffeine

    one cup instant coffee = 58mg caffeine

    express = 77mg caffeine

    If I have a morning match, I drink coffee. I just can't drink scotch that early.

    However, if I have an afternoon or evening match, I'll drink a good shot of whisky beforehand. It definitely loosens me up.

    Not sure if you are serious about this. However, a small/half shot of scotch might very well be beneficial for your match play. Many athletes find that 1/2 glass of wine or 1/3 to 1/2 beer will relax the mind and facilitate a peak performance. A full serving of alcohol is not recommended. This much alcohol will start to dull the senses -- slow down RT/reflexes and impair judgement. More is not better.

    I would hardly characterize it as irrelevant data. It is a valid perspective. For those with high blood pressure (hypertension) or those who are pre-hypertensive, this should probably be a concern.

    I have measured my own blood pressure before & after tennis/exercise when I have ingested 1-2 oz of an energy shot drink. I have not detected any issues in my own case. Also, I do not believe that the energy shot is elevating my heart rate to dangerous levels. In the past, I have regularly performed aerobic exercise where I kept my heart up to 80-85% of my calculated max for extended periods of time. However, with the combination of the energy shot + tennis, I do not believe that I am getting my heart rate close to that range for any more than a few seconds at a time.

    I only take half..but still I am on the fence about it. Some days I have played a lot better and others I was too spazzy like Mikeler described.

    Evening tennis I take nothing.

    I was actually serious about the scotch..at least for an evening match..AM would be a little hardcore for me.

    drinking energy drinks is not good for you period. what makes you think it would be ok to do for playing tennis. Cafenine isnt really great for your tennis either. I've read about former pros swearing by not taking caf before matches.

    I believe that this data is misleading. Several other sources have the caffeine content of the standard 5-Hour Energy at quite a bit less than this. The content for the Extra Strength version of this product is ~ 200 mg.

    http://www.forbes.com/sites/clareoconnor/2012/02/08/whats-in-a-bottle-of-5-hour-energy

    Note that Power Player and I were talking about 1/2 bottle (1 serving) of the standard version of 5-Hour Energy. Altho' many ppl will ingest the whole bottle at 1 sitting, this is really 2 servings, not one. A single serving of the standard version, as I recommended, provides 75-80 mg of caffeine according to other sources. Note that 6 Hour Power (which owns the original formulation of 5-Hour Energy) is a bit less with ~62 mg/oz.

    No, it says "157 mg of caffeine in the regular 5-Hour, and 206 mg in its Extra Strength counterpart.". This is the content for 2 servings.

    Apparently, you did not read past the 2nd paragraph.

    Wikipedia says, "An October 2010 analysis by ConsumerLab.com found the caffeine content of a full bottle of 5-Hour Energy is 207 mg.[7] (It is not clear whether the "Original" or "Extra Strength" product was tested.)"

    Yeah, ABC News did an exclusive on a West Virginia town and their "culture". The residents were oddly addicted to Mountain Dew and most of their teeth were rotten. The local dentist cleaned their teeth for free.... :)

    After filming, the residents went home and opened a bottle of Mountain Dew. :roll:

    From your OWN link:-

    5-hour Energy 1.9 fl. oz. 208

    You keep on saying you think data is misleading (Why? Have you done your own laboratory tests?) but then you just selectively choose data to support your argument. It's tiresome propaganda.

    All you have to do is post all the data from and all the sources and take an average of them if you really must but you're not even prepared to do that.

    It's almost as if you're trying to convince yourself that the drink you drink has low caffeine when the reality is anything but low.

    Tennis is a sport that demands concentration and steady nerves.

    Some can benefit from a little caffeine early in the day or after a long work day - too much and you are jittery and lose focus.



    Tennis players should also be aware that caffeine has a diuretic effect, so be sure to hydrate during practice/play with water or a non-caffeinated sports drink.


    Tennis players should know that caffeine interferes with heat regulation, so overheating is more common on hot days with caffeine.

    Relentless has 160 mg of caffeine in a 16 ounce can.

    By comparison:
    "Acording to The American Beverage Asscoiation

    Coffee, 8oz drip 104-192 mg [depending on the brand]"
    - http://coffeefaq.com/site/how-much-caffeine

    From the USTA Recovery in Tennis booklet:

    "Caffeine

    Caffeine is a naturally occurring stimulant
    that can be found in coffee, tea, caffeinated
    soda, and chocolate in dosages typically
    between 30-200mg of caffeine. A large
    strong coffee could have more than 200mg
    of caffeine. Although caffeine has been
    studied extensively in many sports, showing
    a multitude of physical improvements in
    strength, power, speed and endurance, the
    data is limited in tennis players. The few
    studies that have been conducted have not
    shown positive performance improvements in
    tennis players.
    Recent research on caffeine
    and dehydration show limited evidence
    of caffeine having a negative response
    to thermoregulation or hydration status

    in dosages between 300-400mg per day.
    However, caffeine is not a supplement that is
    recommended for tennis play or competition,
    but under appropriate guidance, may have
    some positive effects for off-court training
    for adult players.
    Large dosages (>500mg per
    day) need to be discouraged, as this could

    There does not seem to be a huge excess of calories in a can of Relentless:

    for me the bottom line is, occasionally an iced coffee or energy drink will help me a bit, even appear to make me play better, and give me a pick me up when i need it... but it's not reliable at all so OCCASIONAL is the key word.. other times it will make me slightly nauseated.

    it's hard to generalize about the caffeine content of coffee. depends on the roast, cup size, bean, etc. a grande regular coffee at starbucks is 330 mg (someone maybe already posted this), more than any energy drink i believe... i believe NOS is the strongest energy drink at 260 mg.

    new harvest organic french roast is sublime, highly recommended

    I think just focusing on caffeine content is a mistake as well. There are other stims in energy drinks that can crank you up in addition to that.

    They are starting to find that Ginkgo biloba could cause cancer so be wary of that.

    The best time for me to take a 5 hour energy is before I go out at night with my friends. That extra B12 really helps me prevent a hangover it seems like (as long as I dont overdo it of course).

    I tried 5 Hour Energy once.

    There was a bit of an initial boost but then I felt terrible very quickly. Have never been tempted to try it again since, the experience was that terrible.

    Eat right, workout, get decent sleep. No tiny bottle can compete with that.

    For me, the best time to drink that utter crap is never.

    Since it seems we're being sensitive around here: not as cool as your post count.
