The double-edged sword of caffeine

[01dragonslayer]

We all know caffeine, a naturally occurring stimulant found in coffee, tea, energy drinks, and various supplements, has long been present in the routines of athletes and fitness enthusiasts. Its ability to enhance alertness, focus, physical performance and even help shed fat due to its thermogenic effect is well-documented. However, there’s a flip side to this seemingly innocent habit – caffeine addiction.

Caffeine is renowned for its stimulating effects on the central nervous system. When consumed in moderate amounts, it can lead to increased endurance, heightened alertness, and improved concentration. These benefits have made it a popular choice among the general population but especially to athletes looking for that extra edge during training or competition.

However, as with most substances, moderation is key. Regular and excessive consumption of caffeine will first lead to tolerance, dependence, and eventually, addiction. Athletes and enthusiasts, driven by the pursuit of better performance, can quickly find themselves trapped at any stage of this cycle. Here are some of the signs that you may have been taking too much caffeine:

Tolerance build-up​

As the body becomes accustomed to caffeine, larger doses are needed to achieve the same stimulating effects. This can lead to an escalating consumption pattern, making the user dependent and increasing the risk of addiction;

Withdrawal symptoms​

If daily caffeine intake is reduced by any means, whether you had a busy day, are traveling or just forgot to buy coffee and ran out of it, withdrawal symptoms show up. These may include headaches, irritability, fatigue, and difficulty concentrating. For athletes, these symptoms can interfere with training and performance;

Disrupted sleep patterns​

Excessive caffeine can disrupt sleep quality and quantity. While it may provide a temporary energy boost, it can lead to long-term sleep disturbances, ultimately undermining an athlete’s health, recovery and overall performance.



The irony lies in the fact that while caffeine initially boosts performance, that fades after some time and starts a process called caffeine crash, when the best course of action is probably just to give the body some rest, but if the person can’t do it at the moment, he will just resort to ingesting more caffeine to keep himself functioning, and that can lead to detrimental effects. Addiction can create a cycle where athletes rely on caffeine to meet performance demands, ultimately compromising their long-term health and well-being.

Recognizing and addressing caffeine addiction is a crucial step towards reclaiming optimal health and performance. Here are some basic strategies you can try to free yourself from this addiction if that’s your case:

Gradual reduction​

Rather than abruptly quitting caffeine, a gradual reduction of intake is recommended. This helps mitigate withdrawal symptoms and allows the body enough time to readjust to lower levels of the substance;

Hydration and nutrition​

Prioritize proper hydration and balanced nutrition to naturally boost energy levels. A proper diet and adequate water intake can help offset the perceived need for caffeine;

Establish healthy sleep patterns​

Prioritize quality sleep as a necessary part of your training regimen. Adequate rest and recovery are fundamental to higher levels of performance. At this point, we’re all also well-aware of the detrimental effects that poor sleep has on one’s health;

Consider professional help​

For people struggling with caffeine addiction, seeking help from a healthcare professional or a nutritionist can be a good option. They can provide individualized strategies and support to help get off of caffeine dependence.



All in all, while caffeine without a doubt offers real performance benefits, it’s very important to approach its consumption with caution and moderation, always keeping in mind that caffeine is a potent substance and its use should not be neglected. Recognizing the signs of addiction and taking proactive steps towards recovery is a testament to a fitness enthusiast’s commitment to long-term success, both on and off the gym. As with other aspects in the world of bodybuilding and physical training, high performance lies in the link between both physical and mental well-being.

I have to question two of these claims. Do you really need increased amounts of caffeine to achieve the same athletic response? The answer seems to be NO.

• Your body does build tolerance to caffeine's general effects (alertness, jitters, etc.). This has nothing to do with performance.
• research suggests the performance-enhancing effects for exercise remain relatively stable even with regular use
• Most studies show habitual caffeine users still get ergogenic benefits from pre-workout doses

While some studies found lesser benefits among regular caffeine users, others suggest habitual consumption does not affect the exercise response.

For decades, I always have a double espresso 45 minutes before I walk in the gym. Get the same results I always have. They key to using caffeine is not to act like a drug addict and just drink caffeine for the buzz it gives you.

Primary Mechanism​

The main mechanism is caffeine's binding to adenosine receptors in the brain, which can directly increase skeletal muscle contractility. This blocks adenosine receptors and prevents the inhibition that adenosine causes on the central nervous system, producing CNS stimulation that facilitates the recruitment of muscle fibers during maximal and submaximal muscle contractions.

Performance Effects
Research shows convincing evidence that caffeine improves one-repetition maximum, isometric and isokinetic strength, plus muscular endurance, velocity, and power in different resistance exercises, loads, and set protocols.
Specifically:

• Movement velocity and power: Meta-analysis shows caffeine significantly enhances both mean velocity and mean power output during resistance exercises, with small effect sizes of 0.42 and 0.21 respectively
• Maximal strength: Studies in women habituated to caffeine showed 3 mg/kg and 6 mg/kg doses both increased 1RM bench press performance compared to placebo, with a dose-response effect between the two caffeine doses.

Lower doses around 2-3 mg/kg appear comparably effective to higher doses like 6 mg/kg, with minimal effective doses around 1.5 mg/kg. A typical cup of coffee contains 80-100 mg of caffeine, which likely falls in that effective range for most people regardless of body weight.

As far as addiction goes, addiction of caffeine has yet to be observed in humans. The American Psychiatric Association recognises caffeine withdrawal as a psychiatric condition, but caffeine use disorder does not currently qualify as a formal diagnosis. This is not the same as addiction in a clinical sense. Addiction involves compulsive use despite harm, which caffeine typically doesn't cause. Having symptoms like headache, fatigue, and difficulty concentrating does not mean you are addicted. Consistent use for performance is a strategic choice, not compulsive behavior. Again, it is a difference in being a drug addict or someone who is useing the benefits of caring for performance purposes.

The only individuals needing medical supervision may be warranted for individuals with underlying anxiety disorders, depression, or other mental health conditions who may experience more severe withdrawal symptoms, people taking medications that interact with caffeine, pregnant women, or individuals with cardiovascular conditions.

I see kids in classes where I teach with Monster caffeine drinks in their hands 24/7. That amount of caffeine in the body is definitely not so healthy.

Cardiovascular effects:

• Fast heartbeat and muscle tremors can occur from excessive intake.
• Elevated blood pressure is a risk factor for heart attack and stroke because it may damage arteries over time, restricting blood flow to the heart and brain.
• Very high doses can cause irregular heartbeat (a-fib) and even death.

Energy drinks (containing 304-320 mg caffeine plus other ingredients) caused QT prolongation of 6-7 milliseconds compared to placebo, and increased systolic blood pressure by about 5 mm Hg. Yet I see some drink these like they are water.

Interesting stats.....a study analyzing 223 million emergency department visits from 2017 to 2023 found that the rate of visits due to caffeine overdose or adverse effects more than doubled among middle school-aged kids (from 3.1 to 6.5 per 100,000 visits) and increased for teens aged 15-18 (from 7.4 to 13.6 per 100,000 visits) during that period.

Absolutely,, moderation is the key!
