A Take a look at the Science


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

One factor I instantly seen as I turned extra ingrained in weight lifting tradition is the recognition of pre-workout dietary supplements.

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

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

The humorous factor is, as a runner I by no means thought-about 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 increase 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 increase efficiency.

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

Then just a few 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 elements listing to see if it would 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 working and exercise efficiency.

Ideally, we’d need 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. Improve cardio effectivity (serving to us enhance VO2max, and so forth)
  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 on your exercise (i.e carbohydrates and glycogen). That’s fully totally different topic and tremendously will depend on your aim race distance. Nonetheless, we do have a variety of articles on the topic right here.

Likewise, the kind of pre-workout I’m recommending on this article is targeted on exhausting 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 effectively.

With that stated, let’s check out a few of 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 stream so your muscle tissues look larger. Nonetheless, once I was doing my preliminary analysis I seen that most of the results may additionally translate to cardio efficiency (plasma focus, improved vascular operate, 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 could be important.

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

  • Citrulline malate ingestion resulted in a big discount within the sensation of fatigue
  • A 34% enhance within the fee of oxidative ATP manufacturing throughout train,
  • A 20% enhance within the fee 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 skill to extend energy. It’s why lifters take it; however, what about working enhancements?

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

My idea had been that will increase in ATP storage would additionally result in elevated working 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 working.

Effectively, 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 by 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 side the carbohydrates eating regimen to boost ranges of glycogen saved within the muscle cells, with a latest 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 exhausting.

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

Caffeine has additionally been proven to boost your skill to burn fats as a gas 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 tissues to contract and chill out). Improved neuromuscular coordination permits your leg muscle tissues to fireplace sooner and extra forcefully, which implies you’ll be extra environment friendly.

Lastly, searching for 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 figuring out can undoubtedly 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 last 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 in case you are an untrained runner, however when you’ve been placing in good coaching, you’re not prone to see any increase in efficiency.

We additionally must take into account that abdomen sensitivity is a priority for runners, however not as a lot for different sorts 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 uncomfortable side effects particular to runners.

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

In case you are contemplating a pre-workout, how and when must you 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 would use it for shorter tempo and threshold periods as effectively, however the efficiency advantages decline the longer your exercises.
  3. You can too use a pre-workout earlier than races 1-mile to 5k. You may take it earlier than longer races, however once more the proof isn’t as robust.
  4. Look to take a pre-workout about 30 minutes earlier than your exercise or race. This offers time for the elements to get into your blood stream and start working.

When you’re desirous about attempting 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 elements with no fillers or patented formulation (which I hate) and comprises efficacious dosages. A whole lot of pre-workouts, particularly within the bodybuilding world, are stuffed with junk to make the label look higher.

I gave Dash a “take a look at run” and actually favored 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 associate of RunnersConnect. In truth, their pre-workout is how I discovered about them and why I wished to associate within the first place (I favored 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 a few of the analysis behind efficient elements.

Be at liberty to go away 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 might be efficient in a pre-workout.
