• Caffeine Pre Workout

    Caffeine

    Can’t sleep because you had too much caffeine. Can’t function without caffeine because you didn’t get enough sleep.

    Caffeine is the most widely used drug in the world and in the world of health and fitness, it’s something we’re obsessed with.

    Research by The British Coffee Association has discovered that:

    • In the UK, we drink approximately 55 million cups of coffee per day. (Research by The British Coffee Association)
    • Gimoka has found that people in UK drink 70 million cups of coffee per day, compared to 165 million cups of tea. Average British male coffee drinker drinks 13 cups per week, while average British female coffee drinker drinks 11.

    What does caffeine do?

    Caffeine is addictive, ask any coffee lover, but what does it actually do? Caffeine is a central nervous system stimulant best known for it’s effect on tiredness, making you feel more focused and alert. For a coffee virgin, the increase in caffeine may give them the jitters, but after time a tolerance is developed.

    Once caffeine hits your bloodstream (about 45-60 minutes after ingestion) it does more than just wake you up, blood pressure, pulse rate and stomach acid production are increased, fat stores are broken down and fatty acids are released into the bloodstream, but just like with the jitters, after a time a tolerance is developed and a regular user will experience little effect. It’s caffeine’s ability to break down fat which is particularly important in athletic performance which we’ll explore later on.

    How long does caffeine take to kick in?

    It takes 45-60 minutes for caffeine to reach it’s highest levels in the blood stream, however you will notice the effects of caffeine after just 10 minutes. The half-life for caffeine is 4-6 hours which explains why there’s no coffee after 4 to preserve a good night's sleep.

    What is pre workout?

    Pre workout does for me what spinach does for popeye. It’s the miracle juice that takes you from zero to hero. It’s the little voice in your ear that says “you can do this” and forces you to attempt one-more-rep. Pre workout are drinks or tablets designed for you to take prior to a training session, pumped full of ingredients to pump up your performance, the key one being, caffeine. Why? As well as getting you more alert, motivated and focused on your workout, caffeine has the ability to increase pain tolerance during exercise, meaning you can lift more before fatiguing.

    Caffeine's effect on pain has been explored in more than just the workout world, with common pain relief tablets such as paracetamol and ibuprofen now containing caffeine, which is thought to make the pain relief more effective.

    Is coffee the best pre workout ever?

    The most popular effects of any pre workout are alertness, increased focus, minimal fatigue, boosted strength and fat loss. The average cost of a pre workout will set you back about £30, which we’d presume is the cost for all these special ingredients no-one can pronounce, right? However caffeine can have all of these effects at a fraction of the cost.

    Research by the International Journal of Sports Nutrition and Exercise Metabolism found that exercisers who had 4.5 mg of caffeine per kilogram of body weight burned more calories! During an hour-long cardio session they had an increased energy expenditure of 15% for up to 3 hours compared to those who only received a placebo.

    The average coffee has anything from 100mg-200mg of caffeine. The additional calorie burn happens due to the extra energy costs of ventilation.

    Caffeine gives you the energy to work harder and therefore burn more calories in order to recover.

    The average pre workout has approximately 150 - 300 mg of caffeine.

    Benefits of caffeine

    A recent document published on the caffeine informer found that caffeine can potentially create effects such as:

    • Increased memory. A study by Johns Hopkins University showed that a 200mg caffeine pill helped boost memory consolidation.
    • Caffeine combined with carbohydrates helps replenish muscle glycogen concentrations faster after exercise.
    • Caffeine helps keep you alert while driving during periods of sleep restriction.
    • Caffeine can stimulate hair growth on balding men and women, however the amount of caffeine needed for this effect is the equivalent of about 60 cups of coffee.
    • Caffeine relieves post-workout muscle pain by up to 48%.
    • Caffeine helps improve memory.
    • Caffeine increases stamina during exercise.
    • People who consume caffeine have a lower risk of suicide.
    • Caffeine improves reaction times
    • Caffeine may help those trying to lose weight: Research out of Germany showed that weight loss study participants who drank 2-4 cups of caffeinated coffee a day were more likely to be successful at keeping the weight off than those who did not consume caffeine.

  • Can Caffeine enhance your training?

    I am going to write this article, but, first, coffee.

    Many of us start our days with caffeine, we throw back the duvet, plod down the stairs, flick a switch on the kettle and wait for its first beautiful brew before we can even think about functioning like a regular human being. Whether it’s tea, coffee or energy drinks most of us will have a caffeine craving that takes us from the walking dead to walking into work.

    Coffee for Caffeine

    What is Caffeine?

    We know it's in our much-loved teas and coffees and that if we don’t have it, things are going to get ugly, but their is far more to caffeine than just that. Caffeine is the most widely used drug in the world. An alkaloid compound, it is a central nervous system stimulant and part of the methylxanthine class, which are naturally occurring substances. It’s most recognisable ability is to block the actions of adenosine. What this means to you and I, is it prevents drowsiness and stops us from grabbing any shut eye. Appearing at its purest in the form of white crystals caffeine can also be found naturally in many forms including coffee beans, tea leaves, yoko bark, kola nuts and guarana seeds. Interestingly guarana is often an ingredient found in weight loss tablets.

    What happens when Caffeine enters the body?

    Caffeine is absorbed quickly through the stomach and intestine and typically is at its peak in our bloodstream 15- 45 minutes after ingestion. In humans it’s effect can last anywhere from 4 to 6 hours on average, which is why we’re taught “no coffee before bed”. We’ve already mentioned the alertness which comes as a direct side effect of caffeine, so let's look at its other effects. Ever been caught needing the loo after a coffee? Caffeine is a diuretic, so it’s going to make your trips to the bathroom more frequent, but drinking more of it won’t actually quench your thirst. Caffeine also increases heart rate, blood pressure and stomach acid production, which can help break down fatty stores and release fatty acids into the bloodstream. However the body is quick to adapt its tolerance to caffeine, and these bodily changes will only take their full effect on new users. This is why you’ll find regular users desensitise to its effects and drink what seems to be gallons before they get even an inkling of a caffeine kick. The ‘kick’ itself comes from an extra release of dopamine, our pleasure transmitter, alongside an increase of adrenaline, which gives us the rush. There’s my excuse for being cranky without coffee; blame the lack of dopamine.

    What can Caffeine do for training?

    Now we’ve established it’s main effects in the body, how can we use that for training? Any form of stimulant to enhance training is controversial, legal or otherwise. Is caffeine worth it? When we are training, be it an endurance run or a session in the gym, our bodies are constantly sourcing the energy to give the exercise our all. This energy comes in the form of Glycogen, your body's stored form of carbohydrate. Caffeine slows down the speed at which we use up all our glycogen stores, by promoting the use of fat as fuel. Fat is far more abundant than glycogen and what caffeine does is mobilize the body's fat stores to encourage working muscles to save glycogen and use fat as an alternative. The result: More energy to train and enhanced endurance.

    It’s effect on cognitive behaviour can also help our training, caffeine’s ability to prevent mental fatigue can help bring more focus and intention to the training session or event, giving the user that ‘tunnel vision’ enabling them to push harder for an extra rep or a faster mile.

    Another reason we tend to give up with our run or workout is pain. If it hurts, naturally your body is going to want to stop. Caffeine prior to training can help to dull our perception of pain, making us able to work harder for longer. It’s not to say the exercise is getting easier or any less painful, it’s just we become less aware of it. This is why you will often find painkillers contain doses of caffeine, to help alleviate pain.

    With all these benefits, it's no wonder caffeine is the most common supplement used by gym-goers, bodybuilders and many athletes, who believe that caffeine gives them the edge they need to compete.

    Coffee for Caffeine

    Are there any side-effects from using caffeine as workout fuel?

    Whilst so far you’ve probably fallen madly in love with your caffeine, more so with every paragraph, every relationship has its flaws. Firstly, there’s the dehydration, because caffeine causes your body to flush out more water it's important to drink more fluid to replace whats lost in order to avoid muscle cramps and headaches. Ironically caffeine can be both the cause and the cure for this.

    Up next there’s the vicious cycle of sleep deprivation. You’ve had no sleep. You’re tired. You need caffeine to wake up. That caffeine keeps you awake at night and so the cycle continues. Although, once a tolerance is built up this phase can pass, or simply limit drinking to the morning to ensure you can still get your beauty sleep.

    Too much of anything can be bad for you, but with caffeine the symptoms can be severe and an overdose can lead to caffeine ‘intoxication’. Symptoms include jitters, diarrhea and digestive issues, breathing difficulties, headaches, sweating, fever, increased thirst, increased urination, an irregular heartbeat or palpitations and even hallucinations.

    So it’s clear caffeine can be a cruel mistress. But is this enough for you to break up? Probably not. Whilst caffeine does have its problems, when used in moderation its positives outweigh its drawbacks.

    As for me, I don’t have a problem with Caffeine. I have a problem without it. In fact, I’m off to make a coffee now.
