A Have 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 had been efficient, how they labored, and what elements had been really helpful.

In brief, sure, there are positively some elements that may assist 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-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 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 concept – I simply let it sort 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 record 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 have 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 improve VO2max, and so forth)
  3. Scale back fatigue (so we are able to exercise more durable for longer)

I’ll notice that on this context, a pre-workout complement isn’t the identical as fueling in your exercise (i.e carbohydrates and glycogen). That’s fully totally different topic and drastically is determined by your purpose race distance. Nonetheless, we do have loads of articles on the topic right here.

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

With that mentioned, let’s check out a number 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 movement so your muscle tissues look larger. Nonetheless, once I was doing my preliminary analysis I seen that lots of the results might 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% improve within the charge of oxidative ATP manufacturing throughout train,
  • A 20% improve within the charge of phosphocreatine restoration after train

This research has been backed up by quite a few different research, concluding that blood movement 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 capability to extend energy. It’s why lifters take it; however, what about operating enhancements?

Nicely, creatine works by serving to improve 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.

Nicely, a 2003 research within the Worldwide Journal of Sport Diet demonstrated that creatine supplementation led to a 5% improve in lactate threshold throughout interval coaching.

These findings have been confirmed, primarily via a 2019 meta-analysis of current analysis on creatine and train efficiency and confirmed a 7.5% improve in efficiency in these taking creatine.

Creatine has additionally been proven to work together with the carbohydrates eating regimen to boost ranges of glycogen saved within the muscle cells, with a current research within the journal Worldwide Society of Sports activities Diet exhibiting a close to 20% improve in saved carbohydrates each earlier than and after a two-hour bout of coaching.


Caffeine is a mainstay with regards to 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 laborious.

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

Caffeine has additionally been proven to reinforce your capability 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 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 loosen up). Improved neuromuscular coordination permits your leg muscle tissues to fireplace quicker and extra forcefully, which suggests 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 quicker simply through the use of caffeine.

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

What about different elements

The science on train efficiency is at all times discovering new methods we are able to 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 final 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 in the event you’ve been placing in good coaching, you’re not more likely to see any enhance in efficiency.

We additionally need to remember the fact that abdomen sensitivity is a priority for runners, however not as a lot for different forms 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 may irritate your abdomen.

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

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

If you’re contemplating a pre-workout, how and when must you 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 put it aside for intense interval or VO2max classes. You might use it for shorter tempo and threshold classes as properly, however the efficiency advantages decline the longer your exercises.
  3. You can even use a pre-workout earlier than races 1-mile to 5k. You’ll be able to take it earlier than longer races, however once more the proof isn’t as sturdy.
  4. Look to take a pre-workout about 30 minutes earlier than your exercise or race. This provides time for the elements to get into your blood stream and start working.

When you’re serious about attempting 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 understand I hate) and comprises efficacious dosages. A number 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 attempt, 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 associate of RunnersConnect. The truth is, their pre-workout is how I came upon about them and why I needed to associate within the first place (I preferred their no hidden method strategy and concentrate on runners).

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

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