  • Caffiene before workout

    I haven't had caffiene in 2 months (Used to drink 2 pepsis a day). Today I had a headache and took 2 excedrine about 90 minutes before my workout. Then during my workout I broke my chest press, biceps curl, ab, and rear delt records. My chest press and biceps curl haven't increased much at all in 4 weeks.

    Is this due to the caffiene? Nothing else in my diet or workout has changed much in a month.

    If it is the caffiene, I'd like to take small amounts, like the amount in 1 or 2 excedrine before each torso/arm workout, but I don't need to be taking excedrine. I don't want to take xenadrine because I need to keep some body fat, and I don't want to speed up my already very high metabolism. Is there any supplement with caffiene that has a short time span in the body, like 2 hours, that's not in a diuretic like coffee/pepsi? Would 1 caffiene pill, or maybe 1/2 a pill 1 hour before my workout be a bad idea? Would my body become used to it and need it? Sorry about all the questions. Thanx for any help.

    Anyone have any ideas? Or use caffiene for their workouts?

      Lots of people, including myself, use caffiene as an energy supplement. I find it especially usefull on leg and back days when you can get lazy by the end. I know a lot of runners who take caffiene before long runs. Apparently it lowers the burn and makes you less sore the next day. In terms of dosage, I used to take pills but now I find drinking a big coffee to be just as effective, plus its cheaper.

        here is a couple of articel that may help. I seem to be able to lift more when I use an ECA. I borrowed these from FG

        Many epidemiological and intervention studies have examined the actions of caffeine on human health. The findings are equivocal. We cannot say for certain that caffeine is linked to any health conditions, however, there is emerging evidence of a link with impaired insulin action, hypertension and feelings of stress. With the proliferation of caffeine containing soft drinks and food products, all of which are easily accessed by children, more research is needed to explore the effects of caffeine on human health.

        Diabetes
        Two studies this year reported that caffeine affects insulin action (Kiejzers et al., Diabetes Care 2002; Thong et al Diabetes 2002). The findings are not completely new, but the degree to which the action of insulin was reduced was surprising. Impaired insulin action is the key step in the development of adult-onset diabetes. Impaired insulin means the pancreas is forced to secrete more insulin to have the same effect till at some point the pancreas starts to fail, leading to the death of insulin producing cells.

        In these studies the equivalent of five to six espresso coffees were given either as tablets or injections and the effectiveness of insulin fell by 15 to 50%. This is similar to the effect obesity has on insulin action (lowers insulin action by 40%). It is well known that exercise increases the effectiveness of insulin, but after the ingestion of caffeine, insulin action was impaired, even though the subjects had exercised for one hour (Thong et al., 2002). It is speculated that caffeine activates receptors (adenosine) in adipose tissue, increasing both the concentration of fatty acids in the blood (which in turn may impair insulin action) and blood pressure. Caffeine also increases the levels of the stress hormone adrenaline which may also impair the action of insulin.

        So should we avoid coffee, especially if we have a family history of diabetes? These studies (and no other studies) have proven that caffeine causes the development of diabetes. However, with the proliferation of caffeine containing soft drinks, more research is needed to explore the effects of caffeine on insulin action.

        Hypertension & Stress
        In another study (Lane et al., Psychosomatic Medicine 2002) 500mg of caffeine in the form of two tablets (equivalent to 4-6 cups of coffee) was given on a certain day of the week. Caffeine was found to cause a slight but signifcant increase in blood pressure and subjects reported feeling more stressed on the day they took caffeine; they also had greater levels of stress hormones. People with conditions that are aggravated by stress or who have high blood pressure need to be conscious of the amount of coffee they drink; alternatively they could switch to decaffeinated coffee.

        Heart disease
        Drinking 6 cups of unfiltered plunger coffee a day may increase the risk of heart disease (Grubben et al. AJCN 2000; 71: 480-4) because blood homocysteine and cholesterol levels increased by 10% and triglycerides by 36%. Sesquiterpenes in coffee is removed by filtering and is known to increase blood cholesterol levels. Caffeine may also lower blood levels of vitamin B6 which may explain the effect on homocysteine. However, coffee contains potentially cardio-protective flavonoids which have been shown to be antioxidants. Filtered coffee in moderation (2-3 cups per day) is probably OK.

        Sport
        Coffee has been shown to release fat from fat cells and hence have a possible benefit in a weight control diet. Marathon runners will drink a cup of coffee before a race to prevent hitting the wall. The theory behind this is that glycogen, or sugars, are the primary source of energy in the muscles, whereas fat is used as a ‘back-up’ fuel. Once glycogen supplies are exhausted (after 2 hours of vigorous activity) fat comes more into play, but this is not as easily accessible. Caffeine before a race may release fat into the blood stream quicker and help ‘save’ glycogen so this does not run out suddenly, leaving a feeling of ‘hitting a wall’ (Vinson & Dabbagh; Nut Research 1998; 18 (6): 1067-75).

        Caffeine content of tea and coffee
        Green tea has as much caffeine as black tea. A typical eight-ounce cup of tea prepared from one tea bag brewed for three to five minutes contains 40 milligrams of caffeine, compared with 100 milligrams in a cup of brewed coffee. The caffeine content of tea can range from 20 to 90 milligrams a cup, depending on the blend of tea leaves, method of preparation and length of brewing time, whereas a cup of coffee may contain from 60 to 180 milligrams of caffeine. Decaffeinated tea, like decaffeinated coffee, has about 4 milligrams of caffeine per cup. Instant teas and prepared iced teas, which can be purchased with or without caffeine, may be too highly processed to contain phytochemicals.

        In conclusion, coffee in moderation (2-3 cups per day) is probably not an issue for most adults.

        Caffeine has been used by endurance athletes for years as a way to stay alert and improve endurance. It is one of the best-researched nutritional supplements, and the overwhelming scientific evidence suggests that, in moderation, it has no adverse health effects.

        Raises epinephrine levels
        Increases alertness
        Delays fatigue
        May slightly spare muscle glycogen
        Does not promote body fat loss
        Tips and Cautions

        3-6 mg/kg of caffeine one hour prior to exercise improves overall endurance
        Side effects include nausea, muscle tremor, palpitations and headache
        Potentiates ephedrine side-effects (should not be taken together)
        Acts as a diuretic, so adequate fluid intake is crucial
        Caffeine use is fairly common among athletes at all levels of competition. Keep in mind that caffeine is on the IAOC banned substance list, so athletes in international competition would be wise to moderate its use.

          Ok, that answers the question of whether to use it or not. Thanx for the shitload of info. very useful.

          One more question. What's a good way to get a moderate amount of caffiene (not too much), before a workout? I was thinking 1/2 of a caffiene pill. But I figure there could be a better way. Oh, and I don't drink coffee.

            I would brew some green tea. There is lots of benifits of drinking it. If not ,1/2 or a whole pill will work fine.

              green tea only has about 40 milligrams of caffiene in it. in my opinion, thats enough to get a slight buzz but i dont think it would effect your physical performance enough to be worthwhile, except for its other benifits. you can get pills at most drug stores called wake-ups. theyre supposed to be study-aids but they could be used for energy aswell. they contain 100 milligrams of caffiene each.

                Hmm, I guess I'll try 1/2 a pill, see if that's good enough. I know that the 2 excedrine was good enough. And those shouldn't have too much caffiene. I'll report my findings, thanx for the help guys.

                EDIT:

                Caffiene content:
                Excedrine 65mg (per tablet, 2 tablets recommended dosage)
                Coffee 135mg (average, per cup, brewed, -40mg for instant)
                Caffiene pills (varys per brand) 100-200mg per tablet.
                Green Tea 30mg
                Ginseng Tea 100mg

                for more info, here's a link: http://www.cspinet.org/new/cafchart.htm

                I got some good lifts with 130mg, but was a little shakey, I'm going to try 100mg next.
