A Look at the Science


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

One factor I instantly observed as I turned 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 have been efficient, how they labored, and what components have been really helpful.

In brief, sure, there are undoubtedly some components 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 may need a cup of espresso and a few toast earlier than heading out for a exercise, however taking one thing particular to assist increase my exercise efficiency by no means occurred to me.

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

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

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

In fact, this sparked my intrigue and I began digging into the components listing to see if it'd really be efficient.

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

Let’s breakdown the components and take a look at what the analysis says about how they are able to 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 forth)
  3. Cut back fatigue (so we will exercise more durable for longer)

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

Likewise, the kind of pre-workout I'm recommending on this article is concentrated on onerous pace periods like monitor exercises, VO2max exercises, and so forth. Tempo periods and lengthy runs would have a unique set of efficiency necessities and one thing I'm researching as nicely.

With that stated, let’s check out among the components 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 stream so your muscular tissues look larger. Nonetheless, once I was doing my preliminary analysis I observed that lots of the results can also translate to cardio efficiency (plasma focus, improved vascular perform, and so forth).

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

A research by Bendahan, and so forth al within the British Journal of Sports activities Medication discovered that…

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

This research has been backed up by quite a few different research, concluding that blood stream 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 identified for its potential 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 principle constructing block of ATP, the “bank of energy” we use for explosive muscle contractions.

My idea 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 research 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 via 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 together with the carbohydrates weight loss program to boost ranges of glycogen saved within the muscle cells, with a current research within the journal Worldwide Society of Sports activities Vitamin displaying a close to 20% enhance in saved carbohydrates each earlier than and after a two-hour bout of coaching.


Caffeine is a mainstay on the subject 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 exhibits that caffeine boosts your psychological alertness, improves your temper, and boosts your need to run onerous.

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

Caffeine has additionally been proven to boost your potential to burn fats as a gasoline supply. Most researchers consider 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 vitality.

Caffeine additionally enhances response time and improves neuromuscular coordination (how briskly your mind can ship a sign to your muscular tissues to contract and loosen up). Improved neuromuscular coordination permits your leg muscular tissues to fireside sooner and extra forcefully, which implies you’ll be extra environment friendly.

Lastly, in search of direct efficiency enhancements, researchers in a 2008 research discovered that runners who used caffeine previous to their 5k race improved by 1.0 to 1.1 p.c.

This implies a 20-minute 5k runner would run 10-13 seconds sooner simply by utilizing caffeine.

The literature clearly exhibits that caffeine supplementation earlier than understanding can undoubtedly enhance efficiency.

What about different components

The science on train efficiency is all the time discovering new methods we will enhance efficiency.

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

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

Nonetheless, because the analysis continues to develop, we’re discovering that beetroot juice doesn't fairly reside as much as the hype. There seems to be some profit if you're an untrained runner, however for those who’ve been placing in good coaching, you’re not prone to see any increase 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.

Think about 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 negative effects particular to runners.

That stated, I'm all the time looking out for brand spanking new analysis and concepts and different sports activities/disciplines to see if there’s one thing we will 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 suggest that you simply use a pre-workout earlier than each run. It’s not wanted on simple 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 possibly can use it for shorter tempo and threshold periods as nicely, however the efficiency advantages decline the longer your exercises.

If you happen to’re taken with 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 targeted on runners.

I’ve discovered the Dash to make use of solely efficient components with no fillers or patented formulation (which you recognize I hate) and incorporates efficacious dosages. A whole lot of pre-workouts, particularly within the bodybuilding world, are crammed with junk to make the label look higher.

I gave Dash a “test run” and actually preferred the style and the increase it gave me earlier than my exercise.

If you wish to give it a attempt, use the code RC10 to avoid wasting 10%. Right here’s the hyperlink to the product.

In full disclosure, 6am Run is an official companion of RunnersConnect. Actually, their pre-workout is how I discovered about them and why I needed to companion within the first place (I preferred their no hidden components strategy and deal with 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 components.

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