A Have a look at the Science

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

One factor I instantly seen 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 have been efficient, how they labored, and what components have been truly helpful.

Briefly, sure, there are undoubtedly some components that may show you how 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 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 components and dietary supplements a runner might 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 components record to see if it would truly be efficient.

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

Let’s breakdown the components and take a look at what the analysis says about how they can assist enhance your working 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 will exercise tougher 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 solely completely different topic and drastically is dependent upon your objective 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 concentrated on laborious velocity classes like monitor exercises, VO2max exercises, and so forth. Tempo classes and lengthy runs would have a unique set of efficiency necessities and one thing I’m researching as properly.

With that mentioned, let’s check out a few of 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 move so your muscle tissues look greater. 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 might discover direct enhancements to the cardio system. Seems, the enhancements might be vital.

A examine 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 price of oxidative ATP manufacturing throughout train,
  • A 20% improve within the price of phosphocreatine restoration after train

This examine has been backed up by quite a few different research, concluding that blood move 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 means to extend power. It’s why lifters take it; however, what about working enhancements?

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

My principle 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 truly assist your working.

Effectively, a 2003 examine 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 by way of 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 at the side of the carbohydrates eating regimen to boost ranges of glycogen saved within the muscle cells, with a latest examine 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 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 want to run laborious.

Even higher, caffeine reduces your notion of effort, which makes working 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 velocity 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 muscle tissues to contract and calm down). Improved neuromuscular coordination permits your leg muscle tissues to fireside sooner and extra forcefully, which implies 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 p.c.

This implies a 20-minute 5k runner would run 10-13 seconds sooner simply through the use of 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 at all times 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 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 in case you are an untrained runner, however when you’ve been placing in good coaching, you’re not more likely to see any enhance in efficiency.

We additionally need to needless to say abdomen sensitivity is a priority for runners, however not as a lot for different kinds of train, like biking or lifting.

Contemplate beta-alanine. Some research present that beta-alanine might 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 unwanted effects particular to runners.

That mentioned, I’m at all times 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 will apply to working.

If you’re contemplating a pre-workout, how and when must you take it?

  1. First, I don’t advocate that you simply 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 classes. You might use it for shorter tempo and threshold classes as properly, however the efficiency advantages decline the longer your exercises.
  3. You too can 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 components to get into your blood stream and start working.

For those who’re eager 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 components with no fillers or patented formulation (which I hate) and accommodates efficacious dosages. Loads of pre-workouts, particularly within the bodybuilding world, are crammed with junk to make the label look higher.

I gave Dash a “check 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 companion of RunnersConnect. Actually, their pre-workout is how I came upon about them and why I needed to companion within the first place (I preferred their no hidden method 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 components.

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