A Have a look at the Science



In 2015 I began to experiment extra with energy and weight coaching.

One factor I instantly observed as I grew to become extra ingrained in weight lifting tradition is the recognition of pre-workout dietary supplements.

As my analytical thoughts often does, I began researching if these dietary supplements had been efficient, how they labored, and what elements had been really helpful.

Briefly, sure, there are positively some elements that may enable you enhance efficiency and exercise with extra depth and with better focus (extra on that later).

The humorous factor is, as a runner I by no means thought of a “pre-workout” complement.

I might need a cup of espresso and a few toast earlier than heading out for a exercise, however taking one thing particular to assist enhance my exercise efficiency by no means occurred to me.

That’s when the thought began to kindle behind my thoughts about what elements and dietary supplements a runner may use earlier than exercises to assist enhance efficiency.

I didn’t do something with the thought – I simply let it form of mull behind my thoughts.

Then a number of months in the past I stumbled upon a “pre-workout designed for runners” by 6am Run.

After all, this sparked my intrigue and I began digging into the elements record to see if it’d really be efficient.

So, what does a pre-workout for runners appear to be?

Let’s breakdown the elements and take a look at what the analysis says about how they can assist enhance your operating and exercise efficiency.

Ideally, we’d desire a pre-workout complement for runners to assist us…

  1. Enhance maximal energy output (permitting us to run extra powerfully with much less effort).
  2. Enhance cardio effectivity (serving to us enhance VO2max, and so on)
  3. Scale back fatigue (so we are able to exercise tougher for longer)

I’ll be aware that on this context, a pre-workout complement isn’t the identical as fueling in your exercise (i.e carbohydrates and glycogen). That’s totally totally different topic and vastly depends upon your purpose race distance. Nonetheless, we do have plenty of articles on the topic right here.

Likewise, the kind of pre-workout I’m recommending on this article is targeted on arduous pace periods like observe exercises, VO2max exercises, and so on. Tempo periods and lengthy runs would have a distinct set of efficiency necessities and one thing I’m researching as effectively.

With that mentioned, let’s check out among the elements that may assist enhance exercise efficiency.

L-Citrulline Malate

That is maybe the ingredient I used to be most to see in a pre-workout.

In bodybuilding dietary supplements, L-Citrulline Malate is used to enhance blood circulate so your muscle tissue look greater. Nonetheless, after I was doing my preliminary analysis I observed that most of the results may translate to cardio efficiency (plasma focus, improved vascular operate, and so on).

So, I dug into the analysis a bit extra to see if we may discover direct enhancements to the cardio system. Seems, the enhancements could be vital.

A examine by Bendahan, and so on al within the British Journal of Sports activities Drugs discovered that…

  • Citrulline malate ingestion resulted in a major discount within the sensation of fatigue
  • A 34% enhance within the price of oxidative ATP manufacturing throughout train,
  • A 20% enhance within the price of phosphocreatine restoration after train

This examine has been backed up by quite a few different research, concluding that blood circulate enhancement is the mechanism by which citrulline mallate is ready to enhance cardio efficiency.


That is one other ingredient I used to be actually to see in a runner’s pre-workout.

Pre-workout is broadly recognized for its means to extend energy. It’s why lifters take it; however, what about operating enhancements?

Properly, creatine works by serving to enhance the shop of phosphocreatine, which is the primary constructing block of ATP, the “financial institution of power” we use for explosive muscle contractions.

My principle had been that will increase in ATP storage would additionally result in elevated operating effectivity for top depth dash exercises. So as soon as once more I dug into the analysis to see if creatine can really assist your operating.

Properly, a 2003 examine within the Worldwide Journal of Sport Vitamin demonstrated that creatine supplementation led to a 5% enhance in lactate threshold throughout interval coaching.

These findings have been confirmed, primarily by way of a 2019 meta-analysis of present analysis on creatine and train efficiency and confirmed a 7.5% enhance in efficiency in these taking creatine.

Creatine has additionally been proven to work along with the carbohydrates food regimen to lift ranges of glycogen saved within the muscle cells, with a latest examine within the journal Worldwide Society of Sports activities Vitamin exhibiting a close to 20% enhance in saved carbohydrates each earlier than and after a two-hour bout of coaching.


Caffeine is a mainstay in terms of pre-workout dietary supplements, and it’s no shock given the overwhelming analysis and science-backed enhancements.

Simply as your morning cup of espresso helps you get mentally able to face the day, analysis reveals that caffeine boosts your psychological alertness, improves your temper, and boosts your want to run arduous.

Even higher, caffeine reduces your notion of effort, which makes operating quick really feel simpler.

Caffeine has additionally been proven to boost your means to burn fats as a gasoline supply. Most researchers imagine this occurs as a result of caffeine will increase the variety of fatty acids within the blood stream, which will increase the pace at which your physique can covert fats to usable power.

Caffeine additionally enhances response time and improves neuromuscular coordination (how briskly your mind can ship a sign to your muscle tissue to contract and loosen up). Improved neuromuscular coordination permits your leg muscle tissue to fireplace quicker and extra forcefully, which suggests you’ll be extra environment friendly.

Lastly, searching for direct efficiency enhancements, researchers in a 2008 examine discovered that runners who used caffeine previous to their 5k race improved by 1.0 to 1.1 %.

This implies a 20-minute 5k runner would run 10-13 seconds quicker simply through the use of caffeine.

The literature clearly reveals that caffeine supplementation earlier than figuring out can positively enhance efficiency.

What about different elements

The science on train efficiency is all the time discovering new methods we are able to enhance efficiency.

Whereas there have been different dietary supplements which have proven promise, analysis is commonly inconclusive.

For instance, beet root juice is commonly hailed as the final word endurance runner’s complement.

Nonetheless, because the analysis continues to develop, we’re discovering that beetroot juice doesn’t fairly dwell as much as the hype. There seems to be some profit if you’re an untrained runner, however in case you’ve been placing in good coaching, you’re not more likely to see any enhance in efficiency.

We additionally must understand that abdomen sensitivity is a priority for runners, however not as a lot for different varieties of train, like biking or lifting.

Contemplate beta-alanine. Some research present that beta-alanine may enhance VO2max. Nonetheless, ingesting beta-alanine produces an itching feeling in your pores and skin (paresthesia) and might irritate your abdomen.

Thus, the potential advantages of a complement like beta-alanine don’t match up with the potential uncomfortable side effects particular to runners.

That mentioned, I’m all the time looking out for brand new analysis and concepts and taking a look at different sports activities/disciplines to see if there’s one thing we are able to apply to operating.

In case you are contemplating a pre-workout, how and when do you have to take it?

  1. First, I don’t advocate that you just use a pre-workout earlier than each run. It’s not wanted on straightforward days and the efficiency advantages don’t translate to lengthy runs.
  2. My recommendation is to reserve it for intense interval or VO2max periods. You might use it for shorter tempo and threshold periods as effectively, however the efficiency advantages decline the longer your exercises.

When you’re inquisitive about making an attempt a pre-workout, I like to recommend Dash from 6am Run. They’re one of many few, if solely, pre-workouts particularly centered on runners.

I’ve discovered the Dash to make use of solely efficient elements with no fillers or patented formulation (which you realize I hate) and accommodates efficacious dosages. Loads of pre-workouts, particularly within the bodybuilding world, are full of junk to make the label look higher.

I gave Dash a “take a look at run” and actually preferred the style and the enhance it gave me earlier than my exercise.

If you wish to give it a strive, use the code RC10 to save lots of 10%. Right here’s the hyperlink to the product.

In full disclosure, 6am Run is an official accomplice of RunnersConnect. In truth, their pre-workout is how I came upon about them and why I wished to accomplice within the first place (I preferred their no hidden components method and give attention to runners).

Regardless, I hope you loved delving into the potential for pre-workout dietary supplements and a take a look at among the analysis behind efficient elements.

Be at liberty to depart a remark or get in contact if there’s a complement you wished us to take a look at or are curious to know if it could be efficient in a pre-workout.
