The Science Behind Pre-Workout

Whether you are an aspiring athlete or a gym enthusiast, the consumption of pre-

workout in the athletic community has become more popular than ever. Globally, people

consume pre-workout to enhance workouts or physical performance. However, these people

often don't know what they are ingesting into their bodies. The main components of pre-

workouts are caffeine, L-arginine, B-alanine, and creatine. These components in short allow for

increased muscle strength, enhanced blood flow within muscles, and an increase in nerve

signal function. 

Each pre-workout varies from product to product. However, the ingredients stated above

are what are most commonly found in consumer pre-workouts. Caffeine plays a role in pre-

workout by producing adrenaline and noradrenaline by blocking specific receptors in your brain.

Additionally, caffeine blocks phosphodiesterase. Phosphodiesterase plays an important role in

aerobic respiration as it functions to degrade cyclic adenosine monophosphate (cAM). As cAM

levels rise due to this inhibition adrenaline levels rise which fuel consumers through their

workouts. Moreover, caffeine also functions to limit muscle fatigue and soreness during

workout. 

L-arginine functions in pre-workouts as a precursor of nitric oxide. In short, this

ingredient allows blood vessels to relax and to dilate. This is beneficial to consumers since it

supports muscle gain and enhanced blood flow. Additionally, beta-alanine is a cool ingredient in

pre-workouts because it enables you to have increased muscle energy and endurance. It does

this by acting as a precursor to carnosine. This enables the muscles to contract longer which

delays muscle fatigue. 

Like most drugs, over consumption can lead to health related issues. If pre-workout is

consumed at a rate that is not recommended there could be serious health implications. A

primary issue that often appears is caffeine dependence. Taking caffeine at an increased rate

can lead to increased blood pressure, anxiety, and disturbed sleep patterns. Therefore,

consumers need to be cautious as side effects may arise.

    Hello Matthew! I think this topic is really important. I personally know a lot of people who use pre-workout, but I have been too scared to try it. I appreciate you going into such detail about different ingredients, and possible risks. I definitely agree that moderation is the key for most things in life. Overconsumption of pre-workout is a danger that all users should be aware of. Great explanation!

    Hi Matthew,
    Thank you for laying out the main ingredients of preworkout and each of their effects. I know lots of people who use this but I'm sure many of them don't know what they are putting in their bodies. Are there different types of preworkout that are more or less potentially dangerous than others? What is a red flag ingredient for preworkout?

      Hello Sean, I hope all is well! thank you for your comment on my post. To answer your first question, yes, there are different types of pre-workouts that vary in their ingredients. For example, there are non-stimulant pre-workouts that do not have caffeine in them. These pre-workouts are generally safer because of the lessened risk of developing a dependency on the product. To answer your second question, the largest red flag ingredient is caffeine. Although consumers love the jittery feeling it might bring, taking an excessive amount can lead to insomnia, headaches and even heart palpations.

    Hi Matthew,
    This was a super interesting read because I was considering taking suppplements to enhance my workouts. I was nervous about the negatives that come along with it. I also don't know alot about what is in them and what effects they will have on my body. This was a great explanation on the positives they have on working out.

    Hi Matt,
    I never knew about the other ingredients in preworkout besides caffeine. Those other effects are interesting. I would like to know more before I take preworkout but I also do not plan on taking it because of caffeine dependence. I enjoy the benefits of not depending on caffeine and do not want to get hooked. I am curious - do you take preworkout?

      Hey Calvin, I hope all is well. thank you for commenting on my blog post. Yes, I do take pre-workout weekly. There are many different brands and types of consumer pre-workout. I regularly take non-stimulant pre-workout which is one without caffeine. I do this to avoid becoming caffeine dependent. Additionally, this pre-workout contains all the other ingredients listed above which aid in performance. If you would like to know more about the product Id be happy to give you some insight.

    Hi Matthew! I have used pre-workout in the past before heading to the gym, and reading more about this was awesome as I never really did any research before consuming it. This blog was very informative and I like that I am now aware of how this works in the body and the ingredients it possesses. Like you said, overconsumption can lead to negative effects, as seen with almost every drug. I wonder if there are certain pre-workouts or ingredients in certain pre-workouts one should avoid.

    Hi Matthew! Great information on pre-workout ingredients and effects on the body. I think it shows how pre-workout is more about giving an individual energy to workout due to the caffeine and L-arginine in the powder. Of course it can motivate individuals but it does not necessary make them stronger. I also like how you added that consuming too much can be harmful to the body.

    Hi Matt, a very interesting post about pre-workouts. I exercise and work out avidly and have always speculated into trying pre-workout. I have always been hesitant on trying it since I am not fully aware of what I potentially can be putting into my body. In addition, I am not fully aware of the short and long term side effects of taking pre-workout. Your post does a good job of explaining the fundamental components of pre-workout and what they do, specifically: caffeine, L-arginine, B-alanine, and creatine. Overall, nice job!

      Hey Will, I hope you are doing well. Thank you for the comment on my blog post. I would recommend taking non-stimulant pre-workout if you are still hesitant on the short/long term effects of pre-workout. A non-stimulant pre-workout is one without caffeine. Hence, there is less of a risk of developing a dependency on the product.

    Hi Matt. Awesome work with this! I think it is super interesting to learn about pre-workout on a more molecular level because it is always good to know what we are putting into our bodies daily and the long term effects. For some reason I think of pre-workout in a much more dangerous sense compared to daily coffee consumption, but it really has similar amounts of caffeine! The dependency is definitely real! Awesome job.

Strain-Induced Jamming in a Spirostomum Ambiguum Cell

Spirostomum ambiguum are single-celled organisms that reside on sediment beds of brackish water habitats. These worm-like organisms range in size from 1 to 4 mm and feast on surrounding bacteria. However, there is more to meet the eye regarding this tiny aquatic organism. In a fraction of the time it takes to blink, Spirotomum ambiguum can shrink to more than half its original length. This contraction generates a gravitational force equivalent (g-force - a measure of acceleration) that is 10,000 times greater than that experienced by any other contracting cell. The energy produced is large enough to destroy the internal structures of a cell. However, this single-cell organism manages to dissipate this energy. Manu Prakash and Ray Chang of Stanford University noticed after imaging the insides of Spirostomum ambiguum cells before and after they had undergone a contraction event that their internal structures vacuoles (fluid-filled sacs) appear to entangle in the folds of a membrane-like ...

Did Corona Virus Feel Much Longer than it Actually Was? It May Have Also Changed Your Personality

 Everyone knows of those big historical events in which each person knows exactly where they were and what they were doing when they got the news. The release of the first iPhone, the announcement of the first African American president, and the national legalization of same-sex marriage are just to name a few. Endless monumental events help shape our society and give us a sense of community. Each is revolutionary in its own ways and vary per person, but some happen to make a more direct impact on all of us. Unfortunately, repeated time and time again these events are typically negative due to a trauma stress response. Coronavirus beginning 2020 is and will always be a unifying factor for every person who can recall the events. Its unique, sudden, and unpredictable nature makes it prominent in our government, healthcare, and local communities. What I’ve come to the realization of is that Coronavirus also had a drastic effect on our life order and even our personalities. In an artic...

Slimy Skincare: The Effects of Snail Mucin on Skin

If you’ve been on the right side of TikTok for a decent amount of time, you’ve definitely noticed an uptick in the popularity of snail mucin in skincare. The skincare industry never fails in shifting the goalposts for women all over the world. There is always some new fad or brand that is the “must-have” for the week and then vanishes into obscurity. Even worse, some of these fads can end up negatively impacting your skin. I definitely don’t need to remind anyone of the tragedy that was the St. Ives scrub (holy microtears). Usually, trends in beauty and skincare are driven by brands rather than particular ingredients or additives, which makes the popularity of snail mucin even more notable. Are the beauty influencers finally onto something, or is this yet another damaging trend that no one will remember in a month? A study done in May 2022 using hairless mice as a proxy for human skin showed that snail mucin does in fact lessen the effects of aging. In this study, exposure to UV rays w...
